8 Tips for becoming a coin collector

Do you intend to start a coin collection but have no idea where to start? The following list of tips will help you in your endeavor. We gathered the most important guidelines and recommendations from experts that any novice can apply to become an excellent coin collector.

Know your lingo

Besides being a fascinating pastime, coin collecting comes with its language. So, if you intend to join the world of coin collectors, you may start by learning a few terms. For instance, circulation coins are coins that have been used in commercial transactions over the years.

Commemorative coins, on the other hand, belong to a category of coins that are minted to celebrate an event, an outstanding personality, or an institution. They are also called numismatic coins. As you can quickly glean from the information offered here, they are never used for commercial purposes.

You should also learn about uncirculated coins, minting, face value, along with other terms that will make you the necessary introduction to the world of coin collecting.

 

Find a reputable dealer

You cannot start your collection without coins. That means that you need to be aware of the implications of purchasing coins from shady sources. Always count on a reputable coin dealer, as, otherwise, your collection might end up containing nothing but worthless pieces, or coins for which you cannot prove the provenience and therefore value.

There are many advantages associated with working with an honest coin dealer. For starters, he or she can offer invaluable information on what coins you should purchase. You can also get a correct appraisal of the coins you get, in case you receive them or you already have them from other sources. Last, but not least, a coin dealer can help you sell your collection for the right price, should you decide to do that at some point.

Invest a little in equipment

To learn about coins, you need to scrutinize them. While the naked eye can only do this much, to observe details that are too minuscule to see without extra help, you need something more. Some people prefer a microscope for coins, so think whether such an investment is justified, in case you’re not yet convinced that you want to get busy with coin collecting in your spare time.

You should have latex or cotton gloves for manipulating the coins since, while they are made of metal and resistant to wear and tear, they can get scratched and damaged, especially their surface. Find a place where you can store your coins, and place your case of coins somewhere away from any damage, be it excessive humidity, or anything else.

Or get the right magnifying glass

You might not have heard so far about the existence of a particular magnifying glass for coins, but such items do exist, and they have specific characteristics that you must bear in mind. Experts recommend getting a model with at least 7x magnification so that you can see all the details without any problem.

Others believe that a magnification of 2x or 3x is enough for a beginner. In case your eyesight is not the best, you should opt for a model with a higher magnification just so that you don’t have to squint and force your eyes when you’re examining your prized collection of coins.

Learn to be organized

Even if you don’t care about investing in equipment, and a magnifying glass for reading is enough for examining the coins in your collection, you should learn how to be organized. Cardboard folders are an easy choice if you want to keep your coins in the same place, and away from harm of any kind.

An idea that experts insist on is to label all the coins and write the specs underneath each coin. This way, you will be able to group different coins, and you will not have to worry about getting them mixed up.

This operation, however, requires a bit of time, and you might also have to educate yourself on the importance and value of each coin in your collection.

Never think as an investor

Coin collecting can be a productive pastime and not only a hobby, but that happens only if you have the proper mindset. If you get into coin collecting just for the sake of making a buck, you have just started on the wrong foot. Investors are guided, in their endeavors, by the need to make a profit. Their goal is to buy low and sell high.

Coins, even when they are collectibles, do not change their value overnight. Collectors, not investors, are those who make a good profit from selling their coins or even entire collections, due to a primary consideration.

They take care of their collections, and thus, they increase their value. A fair return on investment happens years or even decades from purchasing a particular coin.

Always buy coins that look great

Coins, to maintain their value, need to be in as close as mint condition as possible. An old and rare coin might have some minor signs of damage and still maintain its high value, but, as is the case with most coins, they don’t belong to such a narrow category.

So, if you want a rule of thumb for your coin collecting ambitions, you should always invest in good looking coins. Inspect them, if need be, to ensure that they are in good condition.

Never try to remove scratches and signs of damage

Do you know what can be even worse than buying damaged coins? The right answer is: trying to eliminate the signs of damage by polishing the coins or using other methods. Even the least trained coin dealer and collector can tell you that it is a complete no-no to try to recondition damaged coins.

Pay heed to the advice offered just earlier and invest only in pieces that are worth the price. Only in this way, you will be able to populate your collection with valuable pieces that you can later resell.

Have you thought about taking up a new hobby? Do you find coin collecting fascinating, but so far you haven’t thought about it as a way to spend your time in an exciting manner? Maybe the only thing in your way is the simple fact that you don’t know enough things about it. We are here to help you by offering you a list of rules of coin collecting that any beginner should know so that you can avoid bad deals.

Make reasonable purchases from the get-go

Many people feel tempted to believe that they only need one lucky deal and they can get rich. But many professional coin collectors can make such dreams shatter just by examining the coins brought to their attention in this manner with a magnifying glass.

First things first, if you are looking to become a coin collector, you need to learn about coins. Do not throw thousands of dollars on a single item – unless you’re a millionaire and don’t care about losses – and don’t bet on lucky hunches.

There are no such things when it comes to the arduous and exciting hobby of collecting coins. There is, however, a lot of knowledge involved. Also, while you learn, purchase coins that are priced reasonably. They will make the basis of your collection. It is a great starting point.

 

Learn how to store and handle your coins properly

You might think that since coins are made of metal, nothing can damage them unless you pick a sledgehammer and you start trying to make them flat. However, despite this widespread misconception, coins need proper storage conditions. Environment conditions and other factors can damage their surface.

If the design on a face of a coin becomes difficult to see or there are scratches and other signs of damage, the value of that coin decreases. That is why this rule is essential for those who are mere novices.

Don’t attempt to clean your coins! Any coin that undergoes a cleaning process is considered damaged by professionals and, therefore, you end up with nothing but a piece of metal in your hands. When you handle your coins, make sure that you wear latex or cotton gloves. Try to pick the coins only by the edge. Such measures are essential for keeping the value of your coins intact.

Have patience

A coin collection will not be as extensive as you want it to be overnight. This is one of the best pieces of advice someone who is just starting out can receive. Start with an idea. What sort of coins do you want to collect? How would you like to keep your collections organized?

Be aware of situations when you might feel tempted to throw some money just for the sake of completing a collection in the making. Avoid such mistakes. If a deal sounds too good to be true, then that means it is.

Hunt down the pieces that are not yet part of your collection. But always make your purchases from reputable sources, and ask for any certifications and guarantees that may be available.

 

Consider investing in good equipment

Some coin collectors prefer a magnifying glass for coins as the only piece of equipment they need for examining the pieces in their collection. However, the same people tend to have a pretty well-trained eye, and that means that they need only this type of visual enhancement to notice the tiniest details on the coins they collect.

Such a tool is indispensable for beginners, too. It is not expensive, and you can use it while you learn about different coins. However, if you want to examine a new coin that comes to your attention correctly, you might find that a microscope for coins is a better tool for this purpose. Some models are not that expensive, and while they might cost a bit more than a piece of glass that magnifies details, they are still a good deal.

 

Get to know people in the coin collecting world

Coin collecting might not sound like the type of hobby that requires someone to perform a lot of networking, but the truth is, getting to know the right people is essential for being successful in this type of activity.

Where can you find such people? One idea would be to join a coin collecting club. Here you will most likely find other people like you that might have information to share. It doesn’t hurt to attend coin auctions and other related events, as there you will be able to find out about rare coins, their value, and other details that you might not be able to get anywhere else.

Coins are a long-term investment

Coin collecting is not the type of hobby you should expect to yield results from within a short time. A coin you buy today will not change its value overnight. Unless you’re fortunate and you stumble upon an incredible deal, or you find your great-grandfather’s old collection, it is not possible to make a fortune by buying coins today and selling them tomorrow.

Think of your coin collection as a long-term investment. Everyone who is serious about this hobby knows this simple truth well. That is why your chances of finding incredible deals are close to naught. People passionate about numismatics are connoisseurs, and they won’t give up on a valuable coin.

 

Aim for high value

Do not think of your coin collection in terms of quantity. That is a rookie mistake and one that professional collectors never make. A vast collection of one dollar coins is nothing compared to a handful of coins that are valued at thousands of dollars, if not more.

When you make a purchase, search for high-value coins. Get the best price you can. The more valuable coins you have in your collection, the more value your collection as a whole will have. Such a simple rule should put you on the right path of collecting pieces that will bring an extraordinary satisfaction to the collector.

The microscope is an invention without which we wouldn’t be here today. Not only it helped us discover just how incredibly fascinating the microcosmos can be, but it also allowed us to live longer, more exciting and healthier lives. It allowed us to detect the tiny microorganisms that cause disease in humans and it taught us how to get rid of them.

So this begs the next question. Who invented the microscope and why? And the answer we crave is not as simple as we’d like because its origins are disputed between several names in our history. The earliest prototype, if we can even call it that, dates back to the Ancient Roman era, where the Romans used a particular type of glass that magnified objects when you looked through it.

But that was a rudimentary innovation, and it was an accidental discovery that didn’t have any purpose behind it. But then history took another turn when Salvino D’Armate, an Italian scientist created the world’s first eyeglass. But this smart device could only magnify about 5x to 10x and was mostly used to observe larger things such as insects, flowers, and fleas.

The Netherlands and its geniuses

Then something unusual started to happen in the 1590’s, when two Dutch citizens, Zacharias Jansen, and his equally creative father began using lenses in a new way that wasn’t previously experimented with. What they did was that they put a few lenses in an elongated tube, and realized that this organization was about to change the world.

They have realized that the tiny thing at the end of their tube seemed somehow much larger than in real life, much more than a single lens could enlarge something by itself. They didn’t comprehend at that time what would be the implications of this discovery, but it didn’t stop them, and it didn’t curb their enthusiasm in any way.

Although the images obtained with this exciting machine were somehow blurry, they were still enough to impress the public with, since both of them were spectacle men. Unfortunately, none of their microscopes have survived to the modern day, and we only know about them indirectly through a description found in the archives of the Dutch royalty.

Knowing all of this information, we still can’t say the Jansen family invented the microscope since their tools were just overly complicated magnifying glasses. What we call today a microscope is a compound microscope, which is a tool that features two or more lenses, interconnected via a hollow cylinder. The top piece is called an eyepiece or the ocular, and the bottom one is the objective lens.

 

The first pioneer

Most people attribute the invention of the modern microscope to another Dutch person called Anton van Leeuwenhoek, who was a 17th-century scientist who pioneered microscopy. He was the first out of his peers to create and to successfully use a real microscope. His lenses were renowned because they were highly polished and far more superior than the ones of his contemporaries.

His microscope could magnify up to 270x, and it was capable of viewing objects smaller than one-millionth of a meter. Since he was a scientist, he didn’t just make the microscope, but he used it too. Under his polished lenses, he  analyzed bacteria, yeast, and even droplets of water. He described all of them and received many praises from the Royal Society of England, but also a few letters of disbelief, since what he talked about seemed so outlandish.

Now or never

Of course, the Dutchman’s innovative work soon begun to get the attention of scientists all over the world, especially since he was translated into English by Robert Hooke, who published Micrographia in 1665, which is believed to be the first study regarding microscopy.

Hooke is another genius, who took this subject to a whole new level by reinvigorating microscopy and by taking biology into the future.

Modern compound microscopes are indispensable from all laboratories today. And not only that, but they have also have reached into the mainstream, and now anyone who has an interest in science and the intricacy of the world owns one.

A good microscope for students will let you see the mind-blowing detail of any ordinary object, and it will make you a much richer person because you get to be one of the few lucky ones who know that there is more to life than what meets the eye.

Microscopes are optical instruments used in a variety of domains. They are currently employed in medical sciences, lab work, veterinary medicine, as well as a plethora of other activities and fields. Some people use them for crafting handmade jewelry while others utilize such devices for looking at coins.

No microscope is identical with the next, and that’s why not all can be used for repairing electronics or PCB inspection. There are many articles out there that might showcase good microscopes for electronics repair, but the fact of the matter is that your needs should come first when scouring the market for such a model.

Why’s that? The problem with such microscopes is that few of them do a good job in settings that involve something other than vertical inspection. So, if you are looking at components from above, you can definitely use any type of such microscopes. However, if you want to look at any components at an angle, you might find it difficult to track the right model.

In fact, from the research that we have undertaken, it looks like most repair technicians are dissatisfied with the models they’ve tried in the past.

 

Don’t underestimate the power of USB microscopes and borescopes

One of the first mentions that we do have to make is that, as you might have figured out from the headline, not all microscopes are the same. Besides, your specific requirements need to be taken into account. What if we told you that you could do the same with a quality borescope as you would with a quality microscope?

Obviously, there are certain limitations you need to consider if you want to try out your borescope or, as some people call it, endoscope game. There are many models outfitted with multiple types of cameras, and so the magnification power differs largely from one unit to the next. But some of these gadgets are really good at what they’re supposed to do. And some higher end ones even come with their own display.

While a USB microscope cannot be compared to a stereo one when it comes to the quality of the optical components, for instance, it can still be a handy helper in some situations. Moreover, you ought to consider the fact that most USB microscopes actually have higher magnification powers compared to dissecting microscopes. Let’s face it; under some circumstances, you just want to know what’s that you’re seeing. You don’t need the quality of the image to be extremely high.

How to use a stereo microscope to repair an electronic board or any other electronic component

Most standard stereo microscopes are equipped with a boom arm that’s linked to a boom stand. With some models, you have the opportunity to use a knob to customize the position of the arm depending on your application. You can either move the arm from left to right or lower or raise it. This freedom of movement is particularly handy and believe it or not, you’re going to use it many times.

Adjusting the focus on a dissecting microscope is very easy, and that’s because you can move the arm lower or higher to make sure that you get it in the right position. Some models come with extra lens eyepieces with variable magnification powers.

While they do tend to cost a pretty penny when compared to their USB counterparts, dissecting microscopes are far better for electronics repair. Trinocular models will enable you to connect a high-quality camera so that you can see everything on the display of your computer or laptop. For this kind of unit, you don’t even have to focus on a feature like customizable interpupillary distance.

It stands to reason that the camera software can differ largely from one model to the next. With some products, you have the freedom to freeze the image, take a shot, and then move on to other components of the electronic board so as to check for other damages that you have to repair. This particular feature comes in handy when you have to prepare a scientific paper or when you film videos or tutorials for your students.

One of the things that most people fail to understand when it comes to stereo microscopes is why they have such a limited magnification power. The fact of the matter is that electronic boards or other electronic components aren’t as small as bacteria, cells, or tissue samples.

In most cases, you’ll find that the optical components boasted by a quality dissecting microscope are actually better compared to those with which a compound unit has been equipped. Furthermore, such a product will enable repair technicians to do their job properly by allowing them to move the arm in accordance with their momentary needs. Needless to say, this feature doesn’t show up in most compound alternatives.

Understanding the difference between a dissecting and a stereo microscope

On most websites and other online resources, you’ll find that both dissecting and stereo microscopes are treated like the same optical instrument. The fact is that they do tend to differ. There isn’t an exact distinction between these two, as even a dissecting alternative enables the user to benefit from certain freedom of movement.

However, when it comes to the design, a dissecting unit will likely resemble a compound one, which basically means that you won’t have a boom arm whose position you can modify. In addition to that, a dissecting microscope usually comes with too much magnification, which renders it useless for some electronics repair situations.

The point that we are trying to make is that it is a better idea to get a stereo microscope if repairing electronics is the purpose you want to use it for. A magnification of 0.5 to 3x is perfect, but just make sure that the unit is fitted with a ring light with variable controls.

While helping your child getting involved in all sorts of educational and sports activities is nice, you should never neglect his or her curiosity. If you want to expand the universe of your precious little one and show a new world, then there’s no better option other than getting one of the quality and safe microscopes for 7-year-olds available for sale.

Doing so will give your kid plenty of benefits in all sorts of areas that you might not have even thought of. Here are a few ways in which your child might benefit from a microscope.

Exploring a new world

One of the things you should never do is oversimplify things for your kids. You’d be surprised to find out that they’d actually love to know a lot more about the world that you would have thought. Children are like little sponges when it comes to absorbing information about the world, and offering them a microscope is a great way to allow them to learn a lot about microscopic wonders.

Even if biology classes weren’t your thing in school, your kid will benefit immensely from getting a scientific instrument able to unravel a hidden world filled with all sorts of interesting and captivating details. Your kid will learn to use the microscope with some assistance, and you can also choose to get some pre-made slides with various plant and animal species.

 

Learning more about living things

Especially with so many things going on in the world, from climate change to the shrinking of national parks to the extinction of species, now is a great time to teach your child about the importance of life. He or she can observe numerous species, from exotic ones to small creatures living in your backyard.

You’d be surprised to see how fast children catch up and learn. Besides having obvious educational advantages, a microscope can also provide your kid with loads of fun, especially when there are so many things to look at through the magnifying glass.

Getting involved in a wonderful after school activity

In addition to discovering more about the microscopic world that is hidden from our naked eyes, getting a microscope will provide your 7-year-old kid with a productive and entertaining after school activity.

In this modern world that’s dominated by iPhones, computers, and television, it can be a true blessing to get your child to go outside to collect samples and then spend quality time in the company of his little newfound little friends. This would be in contrast to having him stuck in front of a computer for hours on end.

A microscope might actually help your child with school work as he could participate in a science project and bring his own contributions. This would surely stimulate creativity, boost confidence, as well as possibly improve overall attitude towards education.

 

Developing cognitive and motor skills

A microscope is surely not the easiest devices to learn on, especially when the child is young. However, these optical devices come with numerous benefits in terms of improving both cognitive and motor skills.

Your kid will have to learn to operate all those little dials, knobs, and buttons so he might get quite good at handling them. Of course, you can always help when things get complicated, and you can also go for a simpler microscope in the first place.

Another advantage to getting a microscope for your boy or girl is that he or she will also benefit from mental exercises by trying to identify species seen through the eyepieces, putting information together, looking at characteristics and comparing these with those of other species.

You may not realize it yet, but all of these fun ‘exercises’ could help immensely with educating your child and creating a path for a more certain future.

 

Studying to be a scientist

In the world of Silicon Valley companies, everyone wants to be an IT specialist. However, there are few who choose the path of a scientist. This can be a highly rewarding choice, especially given the hefty salaries scientists from top institutes receive.

According to plenty of studies, it can also be rewarding in terms of satisfaction with the job and with life in general. This is because it appears people with higher academic studies and accomplishments tend to be happier.

A microscope might just tip the balance of curiosity and help your child decide on a future career in life sciences. Many of us, grown-ups, regret not having made a choice earlier in our lives, and there’s a great advantage in providing your kid with the means to figure out what he or she would like to do when growing up.

Getting an easy-to-use device

If all the above may sound serious and complicated, you might be glad to learn that you can find plenty of microscope models that are quite easy to use, not to mention extremely fun. You probably shouldn’t actually think of a plastic toy microscope since it would add little to no real value.

Yet there are some instruments that are easy to set-up as well as use. Your child can learn to twist all those dials in no time. There are quite a few beginner microscope sets out there, ranging from the down-right simple to the more complex variants that should still be manageable even by a 7-year-old.

 

Enjoying a versatile device

One of the best things about microscopes nowadays is that they come with plenty of eyepieces, zoom options, lighting systems, adjustments, accessories, etc. What this means for you is that you have a wide range of options at your disposal so that you can make the right choice for your child.

You can get a normal glass microscope that comes with extra safety features, or a smaller and lighter plastic variant that you could upgrade later on, as your kid learns more.

There are also quite a few USB microscope cameras out there that could enable an easy connection to a laptop or computer so that your kid can record and review slides and experiments. This in addition to getting a much clearer view in the first place if you plug the microscope camera into a large screen.

Where can you find such people? One idea would be to join a coin collecting club. Here you will most likely find other people like you that might have information to share. It doesn’t hurt to attend coin auctions and other related events, as there you will be able to find out about rare coins, their value, and other details that you might not be able to get anywhere else.

Coins are a long-term investment

Coin collecting is not the type of hobby you should expect to yield results from within a short time. A coin you buy today will not change its value overnight. Unless you’re fortunate and you stumble upon an incredible deal, or you find your great-grandfather’s old collection, it is not possible to make a fortune by buying coins today and selling them tomorrow.

Think of your coin collection as a long-term investment. Everyone who is serious about this hobby knows this simple truth well. That is why your chances of finding incredible deals are close to naught. People passionate about numismatics are connoisseurs, and they won’t give up on a valuable coin.

 

Aim for high value

Do not think of your coin collection in terms of quantity. That is a rookie mistake and one that professional collectors never make. A vast collection of one dollar coins is nothing compared to a handful of coins that are valued at thousands of dollars, if not more.

When you make a purchase, search for high-value coins. Get the best price you can. The more valuable coins you have in your collection, the more value your collection as a whole will have. Such a simple rule should put you on the right path of collecting pieces that will bring an extraordinary satisfaction to the collector.

The microscope is an invention without which we wouldn’t be here today. Not only it helped us discover just how incredibly fascinating the microcosmos can be, but it also allowed us to live longer, more exciting and healthier lives. It allowed us to detect the tiny microorganisms that cause disease in humans and it taught us how to get rid of them.

So this begs the next question. Who invented the microscope and why? And the answer we crave is not as simple as we’d like because its origins are disputed between several names in our history. The earliest prototype, if we can even call it that, dates back to the Ancient Roman era, where the Romans used a particular type of glass that magnified objects when you looked through it.

But that was a rudimentary innovation, and it was an accidental discovery that didn’t have any purpose behind it. But then history took another turn when Salvino D’Armate, an Italian scientist created the world’s first eyeglass. But this smart device could only magnify about 5x to 10x and was mostly used to observe larger things such as insects, flowers, and fleas.

The Netherlands and its geniuses

Then something unusual started to happen in the 1590’s, when two Dutch citizens, Zacharias Jansen, and his equally creative father began using lenses in a new way that wasn’t previously experimented with. What they did was that they put a few lenses in an elongated tube, and realized that this organization was about to change the world.

They have realized that the tiny thing at the end of their tube seemed somehow much larger than in real life, much more than a single lens could enlarge something by itself. They didn’t comprehend at that time what would be the implications of this discovery, but it didn’t stop them, and it didn’t curb their enthusiasm in any way.

Although the images obtained with this exciting machine were somehow blurry, they were still enough to impress the public with, since both of them were spectacle men. Unfortunately, none of their microscopes have survived to the modern day, and we only know about them indirectly through a description found in the archives of the Dutch royalty.

Knowing all of this information, we still can’t say the Jansen family invented the microscope since their tools were just overly complicated magnifying glasses. What we call today a microscope is a compound microscope, which is a tool that features two or more lenses, interconnected via a hollow cylinder. The top piece is called an eyepiece or the ocular, and the bottom one is the objective lens.

 

The first pioneer

Most people attribute the invention of the modern microscope to another Dutch person called Anton van Leeuwenhoek, who was a 17th-century scientist who pioneered microscopy. He was the first out of his peers to create and to successfully use a real microscope. His lenses were renowned because they were highly polished and far more superior than the ones of his contemporaries.

His microscope could magnify up to 270x, and it was capable of viewing objects smaller than one-millionth of a meter. Since he was a scientist, he didn’t just make the microscope, but he used it too. Under his polished lenses, he  analyzed bacteria, yeast, and even droplets of water. He described all of them and received many praises from the Royal Society of England, but also a few letters of disbelief, since what he talked about seemed so outlandish.

Now or never

Of course, the Dutchman’s innovative work soon begun to get the attention of scientists all over the world, especially since he was translated into English by Robert Hooke, who published Micrographia in 1665, which is believed to be the first study regarding microscopy.

Hooke is another genius, who took this subject to a whole new level by reinvigorating microscopy and by taking biology into the future.

Modern compound microscopes are indispensable from all laboratories today. And not only that, but they have also have reached into the mainstream, and now anyone who has an interest in science and the intricacy of the world owns one.

A good microscope for students will let you see the mind-blowing detail of any ordinary object, and it will make you a much richer person because you get to be one of the few lucky ones who know that there is more to life than what meets the eye.

Microscopes are optical instruments used in a variety of domains. They are currently employed in medical sciences, lab work, veterinary medicine, as well as a plethora of other activities and fields. Some people use them for crafting handmade jewelry while others utilize such devices for looking at coins.

No microscope is identical with the next, and that’s why not all can be used for repairing electronics or PCB inspection. There are many articles out there that might showcase good microscopes for electronics repair, but the fact of the matter is that your needs should come first when scouring the market for such a model.

Why’s that? The problem with such microscopes is that few of them do a good job in settings that involve something other than vertical inspection. So, if you are looking at components from above, you can definitely use any type of such microscopes. However, if you want to look at any components at an angle, you might find it difficult to track the right model.

In fact, from the research that we have undertaken, it looks like most repair technicians are dissatisfied with the models they’ve tried in the past.

 

Don’t underestimate the power of USB microscopes and borescopes

One of the first mentions that we do have to make is that, as you might have figured out from the headline, not all microscopes are the same. Besides, your specific requirements need to be taken into account. What if we told you that you could do the same with a quality borescope as you would with a quality microscope?

Obviously, there are certain limitations you need to consider if you want to try out your borescope or, as some people call it, endoscope game. There are many models outfitted with multiple types of cameras, and so the magnification power differs largely from one unit to the next. But some of these gadgets are really good at what they’re supposed to do. And some higher end ones even come with their own display.

While a USB microscope cannot be compared to a stereo one when it comes to the quality of the optical components, for instance, it can still be a handy helper in some situations. Moreover, you ought to consider the fact that most USB microscopes actually have higher magnification powers compared to dissecting microscopes. Let’s face it; under some circumstances, you just want to know what’s that you’re seeing. You don’t need the quality of the image to be extremely high.

How to use a stereo microscope to repair an electronic board or any other electronic component

Most standard stereo microscopes are equipped with a boom arm that’s linked to a boom stand. With some models, you have the opportunity to use a knob to customize the position of the arm depending on your application. You can either move the arm from left to right or lower or raise it. This freedom of movement is particularly handy and believe it or not, you’re going to use it many times.

Adjusting the focus on a dissecting microscope is very easy, and that’s because you can move the arm lower or higher to make sure that you get it in the right position. Some models come with extra lens eyepieces with variable magnification powers.

While they do tend to cost a pretty penny when compared to their USB counterparts, dissecting microscopes are far better for electronics repair. Trinocular models will enable you to connect a high-quality camera so that you can see everything on the display of your computer or laptop. For this kind of unit, you don’t even have to focus on a feature like customizable interpupillary distance.

It stands to reason that the camera software can differ largely from one model to the next. With some products, you have the freedom to freeze the image, take a shot, and then move on to other components of the electronic board so as to check for other damages that you have to repair. This particular feature comes in handy when you have to prepare a scientific paper or when you film videos or tutorials for your students.

One of the things that most people fail to understand when it comes to stereo microscopes is why they have such a limited magnification power. The fact of the matter is that electronic boards or other electronic components aren’t as small as bacteria, cells, or tissue samples.

In most cases, you’ll find that the optical components boasted by a quality dissecting microscope are actually better compared to those with which a compound unit has been equipped. Furthermore, such a product will enable repair technicians to do their job properly by allowing them to move the arm in accordance with their momentary needs. Needless to say, this feature doesn’t show up in most compound alternatives.

Understanding the difference between a dissecting and a stereo microscope

On most websites and other online resources, you’ll find that both dissecting and stereo microscopes are treated like the same optical instrument. The fact is that they do tend to differ. There isn’t an exact distinction between these two, as even a dissecting alternative enables the user to benefit from certain freedom of movement.

However, when it comes to the design, a dissecting unit will likely resemble a compound one, which basically means that you won’t have a boom arm whose position you can modify. In addition to that, a dissecting microscope usually comes with too much magnification, which renders it useless for some electronics repair situations.

The point that we are trying to make is that it is a better idea to get a stereo microscope if repairing electronics is the purpose you want to use it for. A magnification of 0.5 to 3x is perfect, but just make sure that the unit is fitted with a ring light with variable controls.

While helping your child getting involved in all sorts of educational and sports activities is nice, you should never neglect his or her curiosity. If you want to expand the universe of your precious little one and show a new world, then there’s no better option other than getting one of the quality and safe microscopes for 7-year-olds available for sale.

Doing so will give your kid plenty of benefits in all sorts of areas that you might not have even thought of. Here are a few ways in which your child might benefit from a microscope.

Exploring a new world

One of the things you should never do is oversimplify things for your kids. You’d be surprised to find out that they’d actually love to know a lot more about the world that you would have thought. Children are like little sponges when it comes to absorbing information about the world, and offering them a microscope is a great way to allow them to learn a lot about microscopic wonders.

Even if biology classes weren’t your thing in school, your kid will benefit immensely from getting a scientific instrument able to unravel a hidden world filled with all sorts of interesting and captivating details. Your kid will learn to use the microscope with some assistance, and you can also choose to get some pre-made slides with various plant and animal species.

 

Learning more about living things

Especially with so many things going on in the world, from climate change to the shrinking of national parks to the extinction of species, now is a great time to teach your child about the importance of life. He or she can observe numerous species, from exotic ones to small creatures living in your backyard.

You’d be surprised to see how fast children catch up and learn. Besides having obvious educational advantages, a microscope can also provide your kid with loads of fun, especially when there are so many things to look at through the magnifying glass.

Getting involved in a wonderful after school activity

In addition to discovering more about the microscopic world that is hidden from our naked eyes, getting a microscope will provide your 7-year-old kid with a productive and entertaining after school activity.

In this modern world that’s dominated by iPhones, computers, and television, it can be a true blessing to get your child to go outside to collect samples and then spend quality time in the company of his little newfound little friends. This would be in contrast to having him stuck in front of a computer for hours on end.

A microscope might actually help your child with school work as he could participate in a science project and bring his own contributions. This would surely stimulate creativity, boost confidence, as well as possibly improve overall attitude towards education.

 

Developing cognitive and motor skills

A microscope is surely not the easiest devices to learn on, especially when the child is young. However, these optical devices come with numerous benefits in terms of improving both cognitive and motor skills.

Your kid will have to learn to operate all those little dials, knobs, and buttons so he might get quite good at handling them. Of course, you can always help when things get complicated, and you can also go for a simpler microscope in the first place.

Another advantage to getting a microscope for your boy or girl is that he or she will also benefit from mental exercises by trying to identify species seen through the eyepieces, putting information together, looking at characteristics and comparing these with those of other species.

You may not realize it yet, but all of these fun ‘exercises’ could help immensely with educating your child and creating a path for a more certain future.

 

Studying to be a scientist

In the world of Silicon Valley companies, everyone wants to be an IT specialist. However, there are few who choose the path of a scientist. This can be a highly rewarding choice, especially given the hefty salaries scientists from top institutes receive.

According to plenty of studies, it can also be rewarding in terms of satisfaction with the job and with life in general. This is because it appears people with higher academic studies and accomplishments tend to be happier.

A microscope might just tip the balance of curiosity and help your child decide on a future career in life sciences. Many of us, grown-ups, regret not having made a choice earlier in our lives, and there’s a great advantage in providing your kid with the means to figure out what he or she would like to do when growing up.

Getting an easy-to-use device

If all the above may sound serious and complicated, you might be glad to learn that you can find plenty of microscope models that are quite easy to use, not to mention extremely fun. You probably shouldn’t actually think of a plastic toy microscope since it would add little to no real value.

Yet there are some instruments that are easy to set-up as well as use. Your child can learn to twist all those dials in no time. There are quite a few beginner microscope sets out there, ranging from the down-right simple to the more complex variants that should still be manageable even by a 7-year-old.

 

Enjoying a versatile device

One of the best things about microscopes nowadays is that they come with plenty of eyepieces, zoom options, lighting systems, adjustments, accessories, etc. What this means for you is that you have a wide range of options at your disposal so that you can make the right choice for your child.

You can get a normal glass microscope that comes with extra safety features, or a smaller and lighter plastic variant that you could upgrade later on, as your kid learns more.

There are also quite a few USB microscope cameras out there that could enable an easy connection to a laptop or computer so that your kid can record and review slides and experiments. This in addition to getting a much clearer view in the first place if you plug the microscope camera into a large screen.

Who invented the microscope

Do you intend to start a coin collection but have no idea where to start? The following list of tips will help you in your endeavor. We gathered the most important guidelines and recommendations from experts that any novice can apply to become an excellent coin collector.

Know your lingo

Besides being a fascinating pastime, coin collecting comes with its language. So, if you intend to join the world of coin collectors, you may start by learning a few terms. For instance, circulation coins are coins that have been used in commercial transactions over the years.

Commemorative coins, on the other hand, belong to a category of coins that are minted to celebrate an event, an outstanding personality, or an institution. They are also called numismatic coins. As you can quickly glean from the information offered here, they are never used for commercial purposes.

You should also learn about uncirculated coins, minting, face value, along with other terms that will make you the necessary introduction to the world of coin collecting.

 

Find a reputable dealer

You cannot start your collection without coins. That means that you need to be aware of the implications of purchasing coins from shady sources. Always count on a reputable coin dealer, as, otherwise, your collection might end up containing nothing but worthless pieces, or coins for which you cannot prove the provenience and therefore value.

There are many advantages associated with working with an honest coin dealer. For starters, he or she can offer invaluable information on what coins you should purchase. You can also get a correct appraisal of the coins you get, in case you receive them or you already have them from other sources. Last, but not least, a coin dealer can help you sell your collection for the right price, should you decide to do that at some point.

Invest a little in equipment

To learn about coins, you need to scrutinize them. While the naked eye can only do this much, to observe details that are too minuscule to see without extra help, you need something more. Some people prefer a microscope for coins, so think whether such an investment is justified, in case you’re not yet convinced that you want to get busy with coin collecting in your spare time.

You should have latex or cotton gloves for manipulating the coins since, while they are made of metal and resistant to wear and tear, they can get scratched and damaged, especially their surface. Find a place where you can store your coins, and place your case of coins somewhere away from any damage, be it excessive humidity, or anything else.

Or get the right magnifying glass

You might not have heard so far about the existence of a particular magnifying glass for coins, but such items do exist, and they have specific characteristics that you must bear in mind. Experts recommend getting a model with at least 7x magnification so that you can see all the details without any problem.

Others believe that a magnification of 2x or 3x is enough for a beginner. In case your eyesight is not the best, you should opt for a model with a higher magnification just so that you don’t have to squint and force your eyes when you’re examining your prized collection of coins.

Learn to be organized

Even if you don’t care about investing in equipment, and a magnifying glass for reading is enough for examining the coins in your collection, you should learn how to be organized. Cardboard folders are an easy choice if you want to keep your coins in the same place, and away from harm of any kind.

An idea that experts insist on is to label all the coins and write the specs underneath each coin. This way, you will be able to group different coins, and you will not have to worry about getting them mixed up.

This operation, however, requires a bit of time, and you might also have to educate yourself on the importance and value of each coin in your collection.

Never think as an investor

Coin collecting can be a productive pastime and not only a hobby, but that happens only if you have the proper mindset. If you get into coin collecting just for the sake of making a buck, you have just started on the wrong foot. Investors are guided, in their endeavors, by the need to make a profit. Their goal is to buy low and sell high.

Coins, even when they are collectibles, do not change their value overnight. Collectors, not investors, are those who make a good profit from selling their coins or even entire collections, due to a primary consideration.

They take care of their collections, and thus, they increase their value. A fair return on investment happens years or even decades from purchasing a particular coin.

Always buy coins that look great

Coins, to maintain their value, need to be in as close as mint condition as possible. An old and rare coin might have some minor signs of damage and still maintain its high value, but, as is the case with most coins, they don’t belong to such a narrow category.

So, if you want a rule of thumb for your coin collecting ambitions, you should always invest in good looking coins. Inspect them, if need be, to ensure that they are in good condition.

Never try to remove scratches and signs of damage

Do you know what can be even worse than buying damaged coins? The right answer is: trying to eliminate the signs of damage by polishing the coins or using other methods. Even the least trained coin dealer and collector can tell you that it is a complete no-no to try to recondition damaged coins.

Pay heed to the advice offered just earlier and invest only in pieces that are worth the price. Only in this way, you will be able to populate your collection with valuable pieces that you can later resell.

Have you thought about taking up a new hobby? Do you find coin collecting fascinating, but so far you haven’t thought about it as a way to spend your time in an exciting manner? Maybe the only thing in your way is the simple fact that you don’t know enough things about it. We are here to help you by offering you a list of rules of coin collecting that any beginner should know so that you can avoid bad deals.

Make reasonable purchases from the get-go

Many people feel tempted to believe that they only need one lucky deal and they can get rich. But many professional coin collectors can make such dreams shatter just by examining the coins brought to their attention in this manner with a magnifying glass.

First things first, if you are looking to become a coin collector, you need to learn about coins. Do not throw thousands of dollars on a single item – unless you’re a millionaire and don’t care about losses – and don’t bet on lucky hunches.

There are no such things when it comes to the arduous and exciting hobby of collecting coins. There is, however, a lot of knowledge involved. Also, while you learn, purchase coins that are priced reasonably. They will make the basis of your collection. It is a great starting point.

 

Learn how to store and handle your coins properly

You might think that since coins are made of metal, nothing can damage them unless you pick a sledgehammer and you start trying to make them flat. However, despite this widespread misconception, coins need proper storage conditions. Environment conditions and other factors can damage their surface.

If the design on a face of a coin becomes difficult to see or there are scratches and other signs of damage, the value of that coin decreases. That is why this rule is essential for those who are mere novices.

Don’t attempt to clean your coins! Any coin that undergoes a cleaning process is considered damaged by professionals and, therefore, you end up with nothing but a piece of metal in your hands. When you handle your coins, make sure that you wear latex or cotton gloves. Try to pick the coins only by the edge. Such measures are essential for keeping the value of your coins intact.

Have patience

A coin collection will not be as extensive as you want it to be overnight. This is one of the best pieces of advice someone who is just starting out can receive. Start with an idea. What sort of coins do you want to collect? How would you like to keep your collections organized?

Be aware of situations when you might feel tempted to throw some money just for the sake of completing a collection in the making. Avoid such mistakes. If a deal sounds too good to be true, then that means it is.

Hunt down the pieces that are not yet part of your collection. But always make your purchases from reputable sources, and ask for any certifications and guarantees that may be available.

 

Consider investing in good equipment

Some coin collectors prefer a magnifying glass for coins as the only piece of equipment they need for examining the pieces in their collection. However, the same people tend to have a pretty well-trained eye, and that means that they need only this type of visual enhancement to notice the tiniest details on the coins they collect.

Such a tool is indispensable for beginners, too. It is not expensive, and you can use it while you learn about different coins. However, if you want to examine a new coin that comes to your attention correctly, you might find that a microscope for coins is a better tool for this purpose. Some models are not that expensive, and while they might cost a bit more than a piece of glass that magnifies details, they are still a good deal.

 

Get to know people in the coin collecting world

Coin collecting might not sound like the type of hobby that requires someone to perform a lot of networking, but the truth is, getting to know the right people is essential for being successful in this type of activity.

Where can you find such people? One idea would be to join a coin collecting club. Here you will most likely find other people like you that might have information to share. It doesn’t hurt to attend coin auctions and other related events, as there you will be able to find out about rare coins, their value, and other details that you might not be able to get anywhere else.

Coins are a long-term investment

Coin collecting is not the type of hobby you should expect to yield results from within a short time. A coin you buy today will not change its value overnight. Unless you’re fortunate and you stumble upon an incredible deal, or you find your great-grandfather’s old collection, it is not possible to make a fortune by buying coins today and selling them tomorrow.

While they do tend to cost a pretty penny when compared to their USB counterparts, dissecting microscopes are far better for electronics repair. Trinocular models will enable you to connect a high-quality camera so that you can see everything on the display of your computer or laptop. For this kind of unit, you don’t even have to focus on a feature like customizable interpupillary distance.

It stands to reason that the camera software can differ largely from one model to the next. With some products, you have the freedom to freeze the image, take a shot, and then move on to other components of the electronic board so as to check for other damages that you have to repair. This particular feature comes in handy when you have to prepare a scientific paper or when you film videos or tutorials for your students.

One of the things that most people fail to understand when it comes to stereo microscopes is why they have such a limited magnification power. The fact of the matter is that electronic boards or other electronic components aren’t as small as bacteria, cells, or tissue samples.

In most cases, you’ll find that the optical components boasted by a quality dissecting microscope are actually better compared to those with which a compound unit has been equipped. Furthermore, such a product will enable repair technicians to do their job properly by allowing them to move the arm in accordance with their momentary needs. Needless to say, this feature doesn’t show up in most compound alternatives.

Understanding the difference between a dissecting and a stereo microscope

On most websites and other online resources, you’ll find that both dissecting and stereo microscopes are treated like the same optical instrument. The fact is that they do tend to differ. There isn’t an exact distinction between these two, as even a dissecting alternative enables the user to benefit from certain freedom of movement.

However, when it comes to the design, a dissecting unit will likely resemble a compound one, which basically means that you won’t have a boom arm whose position you can modify. In addition to that, a dissecting microscope usually comes with too much magnification, which renders it useless for some electronics repair situations.

The point that we are trying to make is that it is a better idea to get a stereo microscope if repairing electronics is the purpose you want to use it for. A magnification of 0.5 to 3x is perfect, but just make sure that the unit is fitted with a ring light with variable controls.

While helping your child getting involved in all sorts of educational and sports activities is nice, you should never neglect his or her curiosity. If you want to expand the universe of your precious little one and show a new world, then there’s no better option other than getting one of the quality and safe microscopes for 7-year-olds available for sale.

Doing so will give your kid plenty of benefits in all sorts of areas that you might not have even thought of. Here are a few ways in which your child might benefit from a microscope.

Exploring a new world

One of the things you should never do is oversimplify things for your kids. You’d be surprised to find out that they’d actually love to know a lot more about the world that you would have thought. Children are like little sponges when it comes to absorbing information about the world, and offering them a microscope is a great way to allow them to learn a lot about microscopic wonders.

Even if biology classes weren’t your thing in school, your kid will benefit immensely from getting a scientific instrument able to unravel a hidden world filled with all sorts of interesting and captivating details. Your kid will learn to use the microscope with some assistance, and you can also choose to get some pre-made slides with various plant and animal species.

 

Learning more about living things

Especially with so many things going on in the world, from climate change to the shrinking of national parks to the extinction of species, now is a great time to teach your child about the importance of life. He or she can observe numerous species, from exotic ones to small creatures living in your backyard.

You’d be surprised to see how fast children catch up and learn. Besides having obvious educational advantages, a microscope can also provide your kid with loads of fun, especially when there are so many things to look at through the magnifying glass.

Getting involved in a wonderful after school activity

In addition to discovering more about the microscopic world that is hidden from our naked eyes, getting a microscope will provide your 7-year-old kid with a productive and entertaining after school activity.

In this modern world that’s dominated by iPhones, computers, and television, it can be a true blessing to get your child to go outside to collect samples and then spend quality time in the company of his little newfound little friends. This would be in contrast to having him stuck in front of a computer for hours on end.

A microscope might actually help your child with school work as he could participate in a science project and bring his own contributions. This would surely stimulate creativity, boost confidence, as well as possibly improve overall attitude towards education.

 

Developing cognitive and motor skills

A microscope is surely not the easiest devices to learn on, especially when the child is young. However, these optical devices come with numerous benefits in terms of improving both cognitive and motor skills.

Your kid will have to learn to operate all those little dials, knobs, and buttons so he might get quite good at handling them. Of course, you can always help when things get complicated, and you can also go for a simpler microscope in the first place.

Another advantage to getting a microscope for your boy or girl is that he or she will also benefit from mental exercises by trying to identify species seen through the eyepieces, putting information together, looking at characteristics and comparing these with those of other species.

You may not realize it yet, but all of these fun ‘exercises’ could help immensely with educating your child and creating a path for a more certain future.

 

Studying to be a scientist

In the world of Silicon Valley companies, everyone wants to be an IT specialist. However, there are few who choose the path of a scientist. This can be a highly rewarding choice, especially given the hefty salaries scientists from top institutes receive.

According to plenty of studies, it can also be rewarding in terms of satisfaction with the job and with life in general. This is because it appears people with higher academic studies and accomplishments tend to be happier.

A microscope might just tip the balance of curiosity and help your child decide on a future career in life sciences. Many of us, grown-ups, regret not having made a choice earlier in our lives, and there’s a great advantage in providing your kid with the means to figure out what he or she would like to do when growing up.

Getting an easy-to-use device

If all the above may sound serious and complicated, you might be glad to learn that you can find plenty of microscope models that are quite easy to use, not to mention extremely fun. You probably shouldn’t actually think of a plastic toy microscope since it would add little to no real value.

Yet there are some instruments that are easy to set-up as well as use. Your child can learn to twist all those dials in no time. There are quite a few beginner microscope sets out there, ranging from the down-right simple to the more complex variants that should still be manageable even by a 7-year-old.

 

Enjoying a versatile device

One of the best things about microscopes nowadays is that they come with plenty of eyepieces, zoom options, lighting systems, adjustments, accessories, etc. What this means for you is that you have a wide range of options at your disposal so that you can make the right choice for your child.

You can get a normal glass microscope that comes with extra safety features, or a smaller and lighter plastic variant that you could upgrade later on, as your kid learns more.

There are also quite a few USB microscope cameras out there that could enable an easy connection to a laptop or computer so that your kid can record and review slides and experiments. This in addition to getting a much clearer view in the first place if you plug the microscope camera into a large screen.

How to use a microscope for electronics repair

Do you intend to start a coin collection but have no idea where to start? The following list of tips will help you in your endeavor. We gathered the most important guidelines and recommendations from experts that any novice can apply to become an excellent coin collector.

Know your lingo

Besides being a fascinating pastime, coin collecting comes with its language. So, if you intend to join the world of coin collectors, you may start by learning a few terms. For instance, circulation coins are coins that have been used in commercial transactions over the years.

Commemorative coins, on the other hand, belong to a category of coins that are minted to celebrate an event, an outstanding personality, or an institution. They are also called numismatic coins. As you can quickly glean from the information offered here, they are never used for commercial purposes.

You should also learn about uncirculated coins, minting, face value, along with other terms that will make you the necessary introduction to the world of coin collecting.

 

Find a reputable dealer

You cannot start your collection without coins. That means that you need to be aware of the implications of purchasing coins from shady sources. Always count on a reputable coin dealer, as, otherwise, your collection might end up containing nothing but worthless pieces, or coins for which you cannot prove the provenience and therefore value.

There are many advantages associated with working with an honest coin dealer. For starters, he or she can offer invaluable information on what coins you should purchase. You can also get a correct appraisal of the coins you get, in case you receive them or you already have them from other sources. Last, but not least, a coin dealer can help you sell your collection for the right price, should you decide to do that at some point.

Invest a little in equipment

To learn about coins, you need to scrutinize them. While the naked eye can only do this much, to observe details that are too minuscule to see without extra help, you need something more. Some people prefer a microscope for coins, so think whether such an investment is justified, in case you’re not yet convinced that you want to get busy with coin collecting in your spare time.

You should have latex or cotton gloves for manipulating the coins since, while they are made of metal and resistant to wear and tear, they can get scratched and damaged, especially their surface. Find a place where you can store your coins, and place your case of coins somewhere away from any damage, be it excessive humidity, or anything else.

Or get the right magnifying glass

You might not have heard so far about the existence of a particular magnifying glass for coins, but such items do exist, and they have specific characteristics that you must bear in mind. Experts recommend getting a model with at least 7x magnification so that you can see all the details without any problem.

Others believe that a magnification of 2x or 3x is enough for a beginner. In case your eyesight is not the best, you should opt for a model with a higher magnification just so that you don’t have to squint and force your eyes when you’re examining your prized collection of coins.

Learn to be organized

Even if you don’t care about investing in equipment, and a magnifying glass for reading is enough for examining the coins in your collection, you should learn how to be organized. Cardboard folders are an easy choice if you want to keep your coins in the same place, and away from harm of any kind.

An idea that experts insist on is to label all the coins and write the specs underneath each coin. This way, you will be able to group different coins, and you will not have to worry about getting them mixed up.

This operation, however, requires a bit of time, and you might also have to educate yourself on the importance and value of each coin in your collection.

Never think as an investor

Coin collecting can be a productive pastime and not only a hobby, but that happens only if you have the proper mindset. If you get into coin collecting just for the sake of making a buck, you have just started on the wrong foot. Investors are guided, in their endeavors, by the need to make a profit. Their goal is to buy low and sell high.

Coins, even when they are collectibles, do not change their value overnight. Collectors, not investors, are those who make a good profit from selling their coins or even entire collections, due to a primary consideration.

They take care of their collections, and thus, they increase their value. A fair return on investment happens years or even decades from purchasing a particular coin.

Always buy coins that look great

Coins, to maintain their value, need to be in as close as mint condition as possible. An old and rare coin might have some minor signs of damage and still maintain its high value, but, as is the case with most coins, they don’t belong to such a narrow category.

So, if you want a rule of thumb for your coin collecting ambitions, you should always invest in good looking coins. Inspect them, if need be, to ensure that they are in good condition.

Never try to remove scratches and signs of damage

Do you know what can be even worse than buying damaged coins? The right answer is: trying to eliminate the signs of damage by polishing the coins or using other methods. Even the least trained coin dealer and collector can tell you that it is a complete no-no to try to recondition damaged coins.

Pay heed to the advice offered just earlier and invest only in pieces that are worth the price. Only in this way, you will be able to populate your collection with valuable pieces that you can later resell.

Have you thought about taking up a new hobby? Do you find coin collecting fascinating, but so far you haven’t thought about it as a way to spend your time in an exciting manner? Maybe the only thing in your way is the simple fact that you don’t know enough things about it. We are here to help you by offering you a list of rules of coin collecting that any beginner should know so that you can avoid bad deals.

Make reasonable purchases from the get-go

Many people feel tempted to believe that they only need one lucky deal and they can get rich. But many professional coin collectors can make such dreams shatter just by examining the coins brought to their attention in this manner with a magnifying glass.

First things first, if you are looking to become a coin collector, you need to learn about coins. Do not throw thousands of dollars on a single item – unless you’re a millionaire and don’t care about losses – and don’t bet on lucky hunches.

There are no such things when it comes to the arduous and exciting hobby of collecting coins. There is, however, a lot of knowledge involved. Also, while you learn, purchase coins that are priced reasonably. They will make the basis of your collection. It is a great starting point.

 

Learn how to store and handle your coins properly

You might think that since coins are made of metal, nothing can damage them unless you pick a sledgehammer and you start trying to make them flat. However, despite this widespread misconception, coins need proper storage conditions. Environment conditions and other factors can damage their surface.

If the design on a face of a coin becomes difficult to see or there are scratches and other signs of damage, the value of that coin decreases. That is why this rule is essential for those who are mere novices.

Don’t attempt to clean your coins! Any coin that undergoes a cleaning process is considered damaged by professionals and, therefore, you end up with nothing but a piece of metal in your hands. When you handle your coins, make sure that you wear latex or cotton gloves. Try to pick the coins only by the edge. Such measures are essential for keeping the value of your coins intact.

Have patience

A coin collection will not be as extensive as you want it to be overnight. This is one of the best pieces of advice someone who is just starting out can receive. Start with an idea. What sort of coins do you want to collect? How would you like to keep your collections organized?

Be aware of situations when you might feel tempted to throw some money just for the sake of completing a collection in the making. Avoid such mistakes. If a deal sounds too good to be true, then that means it is.

Hunt down the pieces that are not yet part of your collection. But always make your purchases from reputable sources, and ask for any certifications and guarantees that may be available.

 

Consider investing in good equipment

Some coin collectors prefer a magnifying glass for coins as the only piece of equipment they need for examining the pieces in their collection. However, the same people tend to have a pretty well-trained eye, and that means that they need only this type of visual enhancement to notice the tiniest details on the coins they collect.

Such a tool is indispensable for beginners, too. It is not expensive, and you can use it while you learn about different coins. However, if you want to examine a new coin that comes to your attention correctly, you might find that a microscope for coins is a better tool for this purpose. Some models are not that expensive, and while they might cost a bit more than a piece of glass that magnifies details, they are still a good deal.

 

Get to know people in the coin collecting world

Coin collecting might not sound like the type of hobby that requires someone to perform a lot of networking, but the truth is, getting to know the right people is essential for being successful in this type of activity.

Where can you find such people? One idea would be to join a coin collecting club. Here you will most likely find other people like you that might have information to share. It doesn’t hurt to attend coin auctions and other related events, as there you will be able to find out about rare coins, their value, and other details that you might not be able to get anywhere else.

Coins are a long-term investment

Coin collecting is not the type of hobby you should expect to yield results from within a short time. A coin you buy today will not change its value overnight. Unless you’re fortunate and you stumble upon an incredible deal, or you find your great-grandfather’s old collection, it is not possible to make a fortune by buying coins today and selling them tomorrow.

Think of your coin collection as a long-term investment. Everyone who is serious about this hobby knows this simple truth well. That is why your chances of finding incredible deals are close to naught. People passionate about numismatics are connoisseurs, and they won’t give up on a valuable coin.

 

Aim for high value

Do not think of your coin collection in terms of quantity. That is a rookie mistake and one that professional collectors never make. A vast collection of one dollar coins is nothing compared to a handful of coins that are valued at thousands of dollars, if not more.

When you make a purchase, search for high-value coins. Get the best price you can. The more valuable coins you have in your collection, the more value your collection as a whole will have. Such a simple rule should put you on the right path of collecting pieces that will bring an extraordinary satisfaction to the collector.

The microscope is an invention without which we wouldn’t be here today. Not only it helped us discover just how incredibly fascinating the microcosmos can be, but it also allowed us to live longer, more exciting and healthier lives. It allowed us to detect the tiny microorganisms that cause disease in humans and it taught us how to get rid of them.

So this begs the next question. Who invented the microscope and why? And the answer we crave is not as simple as we’d like because its origins are disputed between several names in our history. The earliest prototype, if we can even call it that, dates back to the Ancient Roman era, where the Romans used a particular type of glass that magnified objects when you looked through it.

But that was a rudimentary innovation, and it was an accidental discovery that didn’t have any purpose behind it. But then history took another turn when Salvino D’Armate, an Italian scientist created the world’s first eyeglass. But this smart device could only magnify about 5x to 10x and was mostly used to observe larger things such as insects, flowers, and fleas.

The Netherlands and its geniuses

Then something unusual started to happen in the 1590’s, when two Dutch citizens, Zacharias Jansen, and his equally creative father began using lenses in a new way that wasn’t previously experimented with. What they did was that they put a few lenses in an elongated tube, and realized that this organization was about to change the world.

They have realized that the tiny thing at the end of their tube seemed somehow much larger than in real life, much more than a single lens could enlarge something by itself. They didn’t comprehend at that time what would be the implications of this discovery, but it didn’t stop them, and it didn’t curb their enthusiasm in any way.

Although the images obtained with this exciting machine were somehow blurry, they were still enough to impress the public with, since both of them were spectacle men. Unfortunately, none of their microscopes have survived to the modern day, and we only know about them indirectly through a description found in the archives of the Dutch royalty.

Knowing all of this information, we still can’t say the Jansen family invented the microscope since their tools were just overly complicated magnifying glasses. What we call today a microscope is a compound microscope, which is a tool that features two or more lenses, interconnected via a hollow cylinder. The top piece is called an eyepiece or the ocular, and the bottom one is the objective lens.

 

The first pioneer

Most people attribute the invention of the modern microscope to another Dutch person called Anton van Leeuwenhoek, who was a 17th-century scientist who pioneered microscopy. He was the first out of his peers to create and to successfully use a real microscope. His lenses were renowned because they were highly polished and far more superior than the ones of his contemporaries.

His microscope could magnify up to 270x, and it was capable of viewing objects smaller than one-millionth of a meter. Since he was a scientist, he didn’t just make the microscope, but he used it too. Under his polished lenses, he  analyzed bacteria, yeast, and even droplets of water. He described all of them and received many praises from the Royal Society of England, but also a few letters of disbelief, since what he talked about seemed so outlandish.

Now or never

Of course, the Dutchman’s innovative work soon begun to get the attention of scientists all over the world, especially since he was translated into English by Robert Hooke, who published Micrographia in 1665, which is believed to be the first study regarding microscopy.

Hooke is another genius, who took this subject to a whole new level by reinvigorating microscopy and by taking biology into the future.

Modern compound microscopes are indispensable from all laboratories today. And not only that, but they have also have reached into the mainstream, and now anyone who has an interest in science and the intricacy of the world owns one.

A good microscope for students will let you see the mind-blowing detail of any ordinary object, and it will make you a much richer person because you get to be one of the few lucky ones who know that there is more to life than what meets the eye.

Microscopes are optical instruments used in a variety of domains. They are currently employed in medical sciences, lab work, veterinary medicine, as well as a plethora of other activities and fields. Some people use them for crafting handmade jewelry while others utilize such devices for looking at coins.

No microscope is identical with the next, and that’s why not all can be used for repairing electronics or PCB inspection. There are many articles out there that might showcase good microscopes for electronics repair, but the fact of the matter is that your needs should come first when scouring the market for such a model.

Why’s that? The problem with such microscopes is that few of them do a good job in settings that involve something other than vertical inspection. So, if you are looking at components from above, you can definitely use any type of such microscopes. However, if you want to look at any components at an angle, you might find it difficult to track the right model.

In fact, from the research that we have undertaken, it looks like most repair technicians are dissatisfied with the models they’ve tried in the past.

 

Don’t underestimate the power of USB microscopes and borescopes

One of the first mentions that we do have to make is that, as you might have figured out from the headline, not all microscopes are the same. Besides, your specific requirements need to be taken into account. What if we told you that you could do the same with a quality borescope as you would with a quality microscope?

Obviously, there are certain limitations you need to consider if you want to try out your borescope or, as some people call it, endoscope game. There are many models outfitted with multiple types of cameras, and so the magnification power differs largely from one unit to the next. But some of these gadgets are really good at what they’re supposed to do. And some higher end ones even come with their own display.

While a USB microscope cannot be compared to a stereo one when it comes to the quality of the optical components, for instance, it can still be a handy helper in some situations. Moreover, you ought to consider the fact that most USB microscopes actually have higher magnification powers compared to dissecting microscopes. Let’s face it; under some circumstances, you just want to know what’s that you’re seeing. You don’t need the quality of the image to be extremely high.

How to use a stereo microscope to repair an electronic board or any other electronic component

Most standard stereo microscopes are equipped with a boom arm that’s linked to a boom stand. With some models, you have the opportunity to use a knob to customize the position of the arm depending on your application. You can either move the arm from left to right or lower or raise it. This freedom of movement is particularly handy and believe it or not, you’re going to use it many times.

Adjusting the focus on a dissecting microscope is very easy, and that’s because you can move the arm lower or higher to make sure that you get it in the right position. Some models come with extra lens eyepieces with variable magnification powers.

While they do tend to cost a pretty penny when compared to their USB counterparts, dissecting microscopes are far better for electronics repair. Trinocular models will enable you to connect a high-quality camera so that you can see everything on the display of your computer or laptop. For this kind of unit, you don’t even have to focus on a feature like customizable interpupillary distance.

It stands to reason that the camera software can differ largely from one model to the next. With some products, you have the freedom to freeze the image, take a shot, and then move on to other components of the electronic board so as to check for other damages that you have to repair. This particular feature comes in handy when you have to prepare a scientific paper or when you film videos or tutorials for your students.

One of the things that most people fail to understand when it comes to stereo microscopes is why they have such a limited magnification power. The fact of the matter is that electronic boards or other electronic components aren’t as small as bacteria, cells, or tissue samples.

In most cases, you’ll find that the optical components boasted by a quality dissecting microscope are actually better compared to those with which a compound unit has been equipped. Furthermore, such a product will enable repair technicians to do their job properly by allowing them to move the arm in accordance with their momentary needs. Needless to say, this feature doesn’t show up in most compound alternatives.

You should also learn about uncirculated coins, minting, face value, along with other terms that will make you the necessary introduction to the world of coin collecting.

 

Find a reputable dealer

You cannot start your collection without coins. That means that you need to be aware of the implications of purchasing coins from shady sources. Always count on a reputable coin dealer, as, otherwise, your collection might end up containing nothing but worthless pieces, or coins for which you cannot prove the provenience and therefore value.

There are many advantages associated with working with an honest coin dealer. For starters, he or she can offer invaluable information on what coins you should purchase. You can also get a correct appraisal of the coins you get, in case you receive them or you already have them from other sources. Last, but not least, a coin dealer can help you sell your collection for the right price, should you decide to do that at some point.

Invest a little in equipment

To learn about coins, you need to scrutinize them. While the naked eye can only do this much, to observe details that are too minuscule to see without extra help, you need something more. Some people prefer a microscope for coins, so think whether such an investment is justified, in case you’re not yet convinced that you want to get busy with coin collecting in your spare time.

You should have latex or cotton gloves for manipulating the coins since, while they are made of metal and resistant to wear and tear, they can get scratched and damaged, especially their surface. Find a place where you can store your coins, and place your case of coins somewhere away from any damage, be it excessive humidity, or anything else.

Or get the right magnifying glass

You might not have heard so far about the existence of a particular magnifying glass for coins, but such items do exist, and they have specific characteristics that you must bear in mind. Experts recommend getting a model with at least 7x magnification so that you can see all the details without any problem.

Others believe that a magnification of 2x or 3x is enough for a beginner. In case your eyesight is not the best, you should opt for a model with a higher magnification just so that you don’t have to squint and force your eyes when you’re examining your prized collection of coins.

Learn to be organized

Even if you don’t care about investing in equipment, and a magnifying glass for reading is enough for examining the coins in your collection, you should learn how to be organized. Cardboard folders are an easy choice if you want to keep your coins in the same place, and away from harm of any kind.

An idea that experts insist on is to label all the coins and write the specs underneath each coin. This way, you will be able to group different coins, and you will not have to worry about getting them mixed up.

This operation, however, requires a bit of time, and you might also have to educate yourself on the importance and value of each coin in your collection.

Never think as an investor

Coin collecting can be a productive pastime and not only a hobby, but that happens only if you have the proper mindset. If you get into coin collecting just for the sake of making a buck, you have just started on the wrong foot. Investors are guided, in their endeavors, by the need to make a profit. Their goal is to buy low and sell high.

Coins, even when they are collectibles, do not change their value overnight. Collectors, not investors, are those who make a good profit from selling their coins or even entire collections, due to a primary consideration.

They take care of their collections, and thus, they increase their value. A fair return on investment happens years or even decades from purchasing a particular coin.

Always buy coins that look great

Coins, to maintain their value, need to be in as close as mint condition as possible. An old and rare coin might have some minor signs of damage and still maintain its high value, but, as is the case with most coins, they don’t belong to such a narrow category.

So, if you want a rule of thumb for your coin collecting ambitions, you should always invest in good looking coins. Inspect them, if need be, to ensure that they are in good condition.

Never try to remove scratches and signs of damage

Do you know what can be even worse than buying damaged coins? The right answer is: trying to eliminate the signs of damage by polishing the coins or using other methods. Even the least trained coin dealer and collector can tell you that it is a complete no-no to try to recondition damaged coins.

Pay heed to the advice offered just earlier and invest only in pieces that are worth the price. Only in this way, you will be able to populate your collection with valuable pieces that you can later resell.

Have you thought about taking up a new hobby? Do you find coin collecting fascinating, but so far you haven’t thought about it as a way to spend your time in an exciting manner? Maybe the only thing in your way is the simple fact that you don’t know enough things about it. We are here to help you by offering you a list of rules of coin collecting that any beginner should know so that you can avoid bad deals.

Make reasonable purchases from the get-go

Many people feel tempted to believe that they only need one lucky deal and they can get rich. But many professional coin collectors can make such dreams shatter just by examining the coins brought to their attention in this manner with a magnifying glass.

First things first, if you are looking to become a coin collector, you need to learn about coins. Do not throw thousands of dollars on a single item – unless you’re a millionaire and don’t care about losses – and don’t bet on lucky hunches.

There are no such things when it comes to the arduous and exciting hobby of collecting coins. There is, however, a lot of knowledge involved. Also, while you learn, purchase coins that are priced reasonably. They will make the basis of your collection. It is a great starting point.

 

Learn how to store and handle your coins properly

You might think that since coins are made of metal, nothing can damage them unless you pick a sledgehammer and you start trying to make them flat. However, despite this widespread misconception, coins need proper storage conditions. Environment conditions and other factors can damage their surface.

If the design on a face of a coin becomes difficult to see or there are scratches and other signs of damage, the value of that coin decreases. That is why this rule is essential for those who are mere novices.

Don’t attempt to clean your coins! Any coin that undergoes a cleaning process is considered damaged by professionals and, therefore, you end up with nothing but a piece of metal in your hands. When you handle your coins, make sure that you wear latex or cotton gloves. Try to pick the coins only by the edge. Such measures are essential for keeping the value of your coins intact.

Have patience

A coin collection will not be as extensive as you want it to be overnight. This is one of the best pieces of advice someone who is just starting out can receive. Start with an idea. What sort of coins do you want to collect? How would you like to keep your collections organized?

Be aware of situations when you might feel tempted to throw some money just for the sake of completing a collection in the making. Avoid such mistakes. If a deal sounds too good to be true, then that means it is.

Hunt down the pieces that are not yet part of your collection. But always make your purchases from reputable sources, and ask for any certifications and guarantees that may be available.

 

Consider investing in good equipment

Some coin collectors prefer a magnifying glass for coins as the only piece of equipment they need for examining the pieces in their collection. However, the same people tend to have a pretty well-trained eye, and that means that they need only this type of visual enhancement to notice the tiniest details on the coins they collect.

Such a tool is indispensable for beginners, too. It is not expensive, and you can use it while you learn about different coins. However, if you want to examine a new coin that comes to your attention correctly, you might find that a microscope for coins is a better tool for this purpose. Some models are not that expensive, and while they might cost a bit more than a piece of glass that magnifies details, they are still a good deal.

 

Get to know people in the coin collecting world

Coin collecting might not sound like the type of hobby that requires someone to perform a lot of networking, but the truth is, getting to know the right people is essential for being successful in this type of activity.

Where can you find such people? One idea would be to join a coin collecting club. Here you will most likely find other people like you that might have information to share. It doesn’t hurt to attend coin auctions and other related events, as there you will be able to find out about rare coins, their value, and other details that you might not be able to get anywhere else.

Coins are a long-term investment

Coin collecting is not the type of hobby you should expect to yield results from within a short time. A coin you buy today will not change its value overnight. Unless you’re fortunate and you stumble upon an incredible deal, or you find your great-grandfather’s old collection, it is not possible to make a fortune by buying coins today and selling them tomorrow.

Think of your coin collection as a long-term investment. Everyone who is serious about this hobby knows this simple truth well. That is why your chances of finding incredible deals are close to naught. People passionate about numismatics are connoisseurs, and they won’t give up on a valuable coin.

 

Aim for high value

Do not think of your coin collection in terms of quantity. That is a rookie mistake and one that professional collectors never make. A vast collection of one dollar coins is nothing compared to a handful of coins that are valued at thousands of dollars, if not more.

When you make a purchase, search for high-value coins. Get the best price you can. The more valuable coins you have in your collection, the more value your collection as a whole will have. Such a simple rule should put you on the right path of collecting pieces that will bring an extraordinary satisfaction to the collector.

The microscope is an invention without which we wouldn’t be here today. Not only it helped us discover just how incredibly fascinating the microcosmos can be, but it also allowed us to live longer, more exciting and healthier lives. It allowed us to detect the tiny microorganisms that cause disease in humans and it taught us how to get rid of them.

So this begs the next question. Who invented the microscope and why? And the answer we crave is not as simple as we’d like because its origins are disputed between several names in our history. The earliest prototype, if we can even call it that, dates back to the Ancient Roman era, where the Romans used a particular type of glass that magnified objects when you looked through it.

But that was a rudimentary innovation, and it was an accidental discovery that didn’t have any purpose behind it. But then history took another turn when Salvino D’Armate, an Italian scientist created the world’s first eyeglass. But this smart device could only magnify about 5x to 10x and was mostly used to observe larger things such as insects, flowers, and fleas.

The Netherlands and its geniuses

Then something unusual started to happen in the 1590’s, when two Dutch citizens, Zacharias Jansen, and his equally creative father began using lenses in a new way that wasn’t previously experimented with. What they did was that they put a few lenses in an elongated tube, and realized that this organization was about to change the world.

They have realized that the tiny thing at the end of their tube seemed somehow much larger than in real life, much more than a single lens could enlarge something by itself. They didn’t comprehend at that time what would be the implications of this discovery, but it didn’t stop them, and it didn’t curb their enthusiasm in any way.

Although the images obtained with this exciting machine were somehow blurry, they were still enough to impress the public with, since both of them were spectacle men. Unfortunately, none of their microscopes have survived to the modern day, and we only know about them indirectly through a description found in the archives of the Dutch royalty.

Knowing all of this information, we still can’t say the Jansen family invented the microscope since their tools were just overly complicated magnifying glasses. What we call today a microscope is a compound microscope, which is a tool that features two or more lenses, interconnected via a hollow cylinder. The top piece is called an eyepiece or the ocular, and the bottom one is the objective lens.

 

The first pioneer

Most people attribute the invention of the modern microscope to another Dutch person called Anton van Leeuwenhoek, who was a 17th-century scientist who pioneered microscopy. He was the first out of his peers to create and to successfully use a real microscope. His lenses were renowned because they were highly polished and far more superior than the ones of his contemporaries.

His microscope could magnify up to 270x, and it was capable of viewing objects smaller than one-millionth of a meter. Since he was a scientist, he didn’t just make the microscope, but he used it too. Under his polished lenses, he  analyzed bacteria, yeast, and even droplets of water. He described all of them and received many praises from the Royal Society of England, but also a few letters of disbelief, since what he talked about seemed so outlandish.

Now or never

Of course, the Dutchman’s innovative work soon begun to get the attention of scientists all over the world, especially since he was translated into English by Robert Hooke, who published Micrographia in 1665, which is believed to be the first study regarding microscopy.

Hooke is another genius, who took this subject to a whole new level by reinvigorating microscopy and by taking biology into the future.

Modern compound microscopes are indispensable from all laboratories today. And not only that, but they have also have reached into the mainstream, and now anyone who has an interest in science and the intricacy of the world owns one.

A good microscope for students will let you see the mind-blowing detail of any ordinary object, and it will make you a much richer person because you get to be one of the few lucky ones who know that there is more to life than what meets the eye.

Microscopes are optical instruments used in a variety of domains. They are currently employed in medical sciences, lab work, veterinary medicine, as well as a plethora of other activities and fields. Some people use them for crafting handmade jewelry while others utilize such devices for looking at coins.

No microscope is identical with the next, and that’s why not all can be used for repairing electronics or PCB inspection. There are many articles out there that might showcase good microscopes for electronics repair, but the fact of the matter is that your needs should come first when scouring the market for such a model.

Why’s that? The problem with such microscopes is that few of them do a good job in settings that involve something other than vertical inspection. So, if you are looking at components from above, you can definitely use any type of such microscopes. However, if you want to look at any components at an angle, you might find it difficult to track the right model.

In fact, from the research that we have undertaken, it looks like most repair technicians are dissatisfied with the models they’ve tried in the past.

 

Don’t underestimate the power of USB microscopes and borescopes

One of the first mentions that we do have to make is that, as you might have figured out from the headline, not all microscopes are the same. Besides, your specific requirements need to be taken into account. What if we told you that you could do the same with a quality borescope as you would with a quality microscope?

Obviously, there are certain limitations you need to consider if you want to try out your borescope or, as some people call it, endoscope game. There are many models outfitted with multiple types of cameras, and so the magnification power differs largely from one unit to the next. But some of these gadgets are really good at what they’re supposed to do. And some higher end ones even come with their own display.

While a USB microscope cannot be compared to a stereo one when it comes to the quality of the optical components, for instance, it can still be a handy helper in some situations. Moreover, you ought to consider the fact that most USB microscopes actually have higher magnification powers compared to dissecting microscopes. Let’s face it; under some circumstances, you just want to know what’s that you’re seeing. You don’t need the quality of the image to be extremely high.

How to use a stereo microscope to repair an electronic board or any other electronic component

Most standard stereo microscopes are equipped with a boom arm that’s linked to a boom stand. With some models, you have the opportunity to use a knob to customize the position of the arm depending on your application. You can either move the arm from left to right or lower or raise it. This freedom of movement is particularly handy and believe it or not, you’re going to use it many times.

Adjusting the focus on a dissecting microscope is very easy, and that’s because you can move the arm lower or higher to make sure that you get it in the right position. Some models come with extra lens eyepieces with variable magnification powers.

While they do tend to cost a pretty penny when compared to their USB counterparts, dissecting microscopes are far better for electronics repair. Trinocular models will enable you to connect a high-quality camera so that you can see everything on the display of your computer or laptop. For this kind of unit, you don’t even have to focus on a feature like customizable interpupillary distance.

It stands to reason that the camera software can differ largely from one model to the next. With some products, you have the freedom to freeze the image, take a shot, and then move on to other components of the electronic board so as to check for other damages that you have to repair. This particular feature comes in handy when you have to prepare a scientific paper or when you film videos or tutorials for your students.

One of the things that most people fail to understand when it comes to stereo microscopes is why they have such a limited magnification power. The fact of the matter is that electronic boards or other electronic components aren’t as small as bacteria, cells, or tissue samples.

In most cases, you’ll find that the optical components boasted by a quality dissecting microscope are actually better compared to those with which a compound unit has been equipped. Furthermore, such a product will enable repair technicians to do their job properly by allowing them to move the arm in accordance with their momentary needs. Needless to say, this feature doesn’t show up in most compound alternatives.

Understanding the difference between a dissecting and a stereo microscope

On most websites and other online resources, you’ll find that both dissecting and stereo microscopes are treated like the same optical instrument. The fact is that they do tend to differ. There isn’t an exact distinction between these two, as even a dissecting alternative enables the user to benefit from certain freedom of movement.

However, when it comes to the design, a dissecting unit will likely resemble a compound one, which basically means that you won’t have a boom arm whose position you can modify. In addition to that, a dissecting microscope usually comes with too much magnification, which renders it useless for some electronics repair situations.

The point that we are trying to make is that it is a better idea to get a stereo microscope if repairing electronics is the purpose you want to use it for. A magnification of 0.5 to 3x is perfect, but just make sure that the unit is fitted with a ring light with variable controls.

While helping your child getting involved in all sorts of educational and sports activities is nice, you should never neglect his or her curiosity. If you want to expand the universe of your precious little one and show a new world, then there’s no better option other than getting one of the quality and safe microscopes for 7-year-olds available for sale.

Doing so will give your kid plenty of benefits in all sorts of areas that you might not have even thought of. Here are a few ways in which your child might benefit from a microscope.

Exploring a new world

One of the things you should never do is oversimplify things for your kids. You’d be surprised to find out that they’d actually love to know a lot more about the world that you would have thought. Children are like little sponges when it comes to absorbing information about the world, and offering them a microscope is a great way to allow them to learn a lot about microscopic wonders.

Even if biology classes weren’t your thing in school, your kid will benefit immensely from getting a scientific instrument able to unravel a hidden world filled with all sorts of interesting and captivating details. Your kid will learn to use the microscope with some assistance, and you can also choose to get some pre-made slides with various plant and animal species.

 

Learning more about living things

Especially with so many things going on in the world, from climate change to the shrinking of national parks to the extinction of species, now is a great time to teach your child about the importance of life. He or she can observe numerous species, from exotic ones to small creatures living in your backyard.

You’d be surprised to see how fast children catch up and learn. Besides having obvious educational advantages, a microscope can also provide your kid with loads of fun, especially when there are so many things to look at through the magnifying glass.

Getting involved in a wonderful after school activity

In addition to discovering more about the microscopic world that is hidden from our naked eyes, getting a microscope will provide your 7-year-old kid with a productive and entertaining after school activity.

In this modern world that’s dominated by iPhones, computers, and television, it can be a true blessing to get your child to go outside to collect samples and then spend quality time in the company of his little newfound little friends. This would be in contrast to having him stuck in front of a computer for hours on end.

A microscope might actually help your child with school work as he could participate in a science project and bring his own contributions. This would surely stimulate creativity, boost confidence, as well as possibly improve overall attitude towards education.

 

Developing cognitive and motor skills

A microscope is surely not the easiest devices to learn on, especially when the child is young. However, these optical devices come with numerous benefits in terms of improving both cognitive and motor skills.

Your kid will have to learn to operate all those little dials, knobs, and buttons so he might get quite good at handling them. Of course, you can always help when things get complicated, and you can also go for a simpler microscope in the first place.

Another advantage to getting a microscope for your boy or girl is that he or she will also benefit from mental exercises by trying to identify species seen through the eyepieces, putting information together, looking at characteristics and comparing these with those of other species.

You may not realize it yet, but all of these fun ‘exercises’ could help immensely with educating your child and creating a path for a more certain future.

 

Studying to be a scientist

In the world of Silicon Valley companies, everyone wants to be an IT specialist. However, there are few who choose the path of a scientist. This can be a highly rewarding choice, especially given the hefty salaries scientists from top institutes receive.

According to plenty of studies, it can also be rewarding in terms of satisfaction with the job and with life in general. This is because it appears people with higher academic studies and accomplishments tend to be happier.

A microscope might just tip the balance of curiosity and help your child decide on a future career in life sciences. Many of us, grown-ups, regret not having made a choice earlier in our lives, and there’s a great advantage in providing your kid with the means to figure out what he or she would like to do when growing up.

Getting an easy-to-use device

If all the above may sound serious and complicated, you might be glad to learn that you can find plenty of microscope models that are quite easy to use, not to mention extremely fun. You probably shouldn’t actually think of a plastic toy microscope since it would add little to no real value.

Yet there are some instruments that are easy to set-up as well as use. Your child can learn to twist all those dials in no time. There are quite a few beginner microscope sets out there, ranging from the down-right simple to the more complex variants that should still be manageable even by a 7-year-old.

 

Enjoying a versatile device

One of the best things about microscopes nowadays is that they come with plenty of eyepieces, zoom options, lighting systems, adjustments, accessories, etc. What this means for you is that you have a wide range of options at your disposal so that you can make the right choice for your child.

You can get a normal glass microscope that comes with extra safety features, or a smaller and lighter plastic variant that you could upgrade later on, as your kid learns more.

There are also quite a few USB microscope cameras out there that could enable an easy connection to a laptop or computer so that your kid can record and review slides and experiments. This in addition to getting a much clearer view in the first place if you plug the microscope camera into a large screen.

Reasons to get a new digital microscope camera now and the benefits of doing so

Do you intend to start a coin collection but have no idea where to start? The following list of tips will help you in your endeavor. We gathered the most important guidelines and recommendations from experts that any novice can apply to become an excellent coin collector.

Know your lingo

Besides being a fascinating pastime, coin collecting comes with its language. So, if you intend to join the world of coin collectors, you may start by learning a few terms. For instance, circulation coins are coins that have been used in commercial transactions over the years.

Commemorative coins, on the other hand, belong to a category of coins that are minted to celebrate an event, an outstanding personality, or an institution. They are also called numismatic coins. As you can quickly glean from the information offered here, they are never used for commercial purposes.

You should also learn about uncirculated coins, minting, face value, along with other terms that will make you the necessary introduction to the world of coin collecting.

Unless you’re fortunate and you stumble upon an incredible deal, or you find your great-grandfather’s old collection, it is not possible to make a fortune by buying coins today and selling them tomorrow.

Think of your coin collection as a long-term investment. Everyone who is serious about this hobby knows this simple truth well. That is why your chances of finding incredible deals are close to naught. People passionate about numismatics are connoisseurs, and they won’t give up on a valuable coin.

 

Aim for high value

Do not think of your coin collection in terms of quantity. That is a rookie mistake and one that professional collectors never make. A vast collection of one dollar coins is nothing compared to a handful of coins that are valued at thousands of dollars, if not more.

When you make a purchase, search for high-value coins. Get the best price you can. The more valuable coins you have in your collection, the more value your collection as a whole will have. Such a simple rule should put you on the right path of collecting pieces that will bring an extraordinary satisfaction to the collector.

The microscope is an invention without which we wouldn’t be here today. Not only it helped us discover just how incredibly fascinating the microcosmos can be, but it also allowed us to live longer, more exciting and healthier lives. It allowed us to detect the tiny microorganisms that cause disease in humans and it taught us how to get rid of them.

So this begs the next question. Who invented the microscope and why? And the answer we crave is not as simple as we’d like because its origins are disputed between several names in our history. The earliest prototype, if we can even call it that, dates back to the Ancient Roman era, where the Romans used a particular type of glass that magnified objects when you looked through it.

But that was a rudimentary innovation, and it was an accidental discovery that didn’t have any purpose behind it. But then history took another turn when Salvino D’Armate, an Italian scientist created the world’s first eyeglass. But this smart device could only magnify about 5x to 10x and was mostly used to observe larger things such as insects, flowers, and fleas.

The Netherlands and its geniuses

Then something unusual started to happen in the 1590’s, when two Dutch citizens, Zacharias Jansen, and his equally creative father began using lenses in a new way that wasn’t previously experimented with. What they did was that they put a few lenses in an elongated tube, and realized that this organization was about to change the world.

They have realized that the tiny thing at the end of their tube seemed somehow much larger than in real life, much more than a single lens could enlarge something by itself. They didn’t comprehend at that time what would be the implications of this discovery, but it didn’t stop them, and it didn’t curb their enthusiasm in any way.

Although the images obtained with this exciting machine were somehow blurry, they were still enough to impress the public with, since both of them were spectacle men. Unfortunately, none of their microscopes have survived to the modern day, and we only know about them indirectly through a description found in the archives of the Dutch royalty.

Knowing all of this information, we still can’t say the Jansen family invented the microscope since their tools were just overly complicated magnifying glasses. What we call today a microscope is a compound microscope, which is a tool that features two or more lenses, interconnected via a hollow cylinder. The top piece is called an eyepiece or the ocular, and the bottom one is the objective lens.

 

The first pioneer

Most people attribute the invention of the modern microscope to another Dutch person called Anton van Leeuwenhoek, who was a 17th-century scientist who pioneered microscopy. He was the first out of his peers to create and to successfully use a real microscope. His lenses were renowned because they were highly polished and far more superior than the ones of his contemporaries.

His microscope could magnify up to 270x, and it was capable of viewing objects smaller than one-millionth of a meter. Since he was a scientist, he didn’t just make the microscope, but he used it too. Under his polished lenses, he  analyzed bacteria, yeast, and even droplets of water. He described all of them and received many praises from the Royal Society of England, but also a few letters of disbelief, since what he talked about seemed so outlandish.

Now or never

Of course, the Dutchman’s innovative work soon begun to get the attention of scientists all over the world, especially since he was translated into English by Robert Hooke, who published Micrographia in 1665, which is believed to be the first study regarding microscopy.

Hooke is another genius, who took this subject to a whole new level by reinvigorating microscopy and by taking biology into the future.

Modern compound microscopes are indispensable from all laboratories today. And not only that, but they have also have reached into the mainstream, and now anyone who has an interest in science and the intricacy of the world owns one.

A good microscope for students will let you see the mind-blowing detail of any ordinary object, and it will make you a much richer person because you get to be one of the few lucky ones who know that there is more to life than what meets the eye.

Microscopes are optical instruments used in a variety of domains. They are currently employed in medical sciences, lab work, veterinary medicine, as well as a plethora of other activities and fields. Some people use them for crafting handmade jewelry while others utilize such devices for looking at coins.

No microscope is identical with the next, and that’s why not all can be used for repairing electronics or PCB inspection. There are many articles out there that might showcase good microscopes for electronics repair, but the fact of the matter is that your needs should come first when scouring the market for such a model.

Why’s that? The problem with such microscopes is that few of them do a good job in settings that involve something other than vertical inspection. So, if you are looking at components from above, you can definitely use any type of such microscopes. However, if you want to look at any components at an angle, you might find it difficult to track the right model.

In fact, from the research that we have undertaken, it looks like most repair technicians are dissatisfied with the models they’ve tried in the past.

 

Don’t underestimate the power of USB microscopes and borescopes

One of the first mentions that we do have to make is that, as you might have figured out from the headline, not all microscopes are the same. Besides, your specific requirements need to be taken into account. What if we told you that you could do the same with a quality borescope as you would with a quality microscope?

Obviously, there are certain limitations you need to consider if you want to try out your borescope or, as some people call it, endoscope game. There are many models outfitted with multiple types of cameras, and so the magnification power differs largely from one unit to the next. But some of these gadgets are really good at what they’re supposed to do. And some higher end ones even come with their own display.

While a USB microscope cannot be compared to a stereo one when it comes to the quality of the optical components, for instance, it can still be a handy helper in some situations. Moreover, you ought to consider the fact that most USB microscopes actually have higher magnification powers compared to dissecting microscopes. Let’s face it; under some circumstances, you just want to know what’s that you’re seeing. You don’t need the quality of the image to be extremely high.

How to use a stereo microscope to repair an electronic board or any other electronic component

Most standard stereo microscopes are equipped with a boom arm that’s linked to a boom stand. With some models, you have the opportunity to use a knob to customize the position of the arm depending on your application. You can either move the arm from left to right or lower or raise it. This freedom of movement is particularly handy and believe it or not, you’re going to use it many times.

Adjusting the focus on a dissecting microscope is very easy, and that’s because you can move the arm lower or higher to make sure that you get it in the right position. Some models come with extra lens eyepieces with variable magnification powers.

While they do tend to cost a pretty penny when compared to their USB counterparts, dissecting microscopes are far better for electronics repair. Trinocular models will enable you to connect a high-quality camera so that you can see everything on the display of your computer or laptop. For this kind of unit, you don’t even have to focus on a feature like customizable interpupillary distance.

It stands to reason that the camera software can differ largely from one model to the next. With some products, you have the freedom to freeze the image, take a shot, and then move on to other components of the electronic board so as to check for other damages that you have to repair. This particular feature comes in handy when you have to prepare a scientific paper or when you film videos or tutorials for your students.

One of the things that most people fail to understand when it comes to stereo microscopes is why they have such a limited magnification power. The fact of the matter is that electronic boards or other electronic components aren’t as small as bacteria, cells, or tissue samples.

In most cases, you’ll find that the optical components boasted by a quality dissecting microscope are actually better compared to those with which a compound unit has been equipped. Furthermore, such a product will enable repair technicians to do their job properly by allowing them to move the arm in accordance with their momentary needs. Needless to say, this feature doesn’t show up in most compound alternatives.

Understanding the difference between a dissecting and a stereo microscope

On most websites and other online resources, you’ll find that both dissecting and stereo microscopes are treated like the same optical instrument. The fact is that they do tend to differ. There isn’t an exact distinction between these two, as even a dissecting alternative enables the user to benefit from certain freedom of movement.

However, when it comes to the design, a dissecting unit will likely resemble a compound one, which basically means that you won’t have a boom arm whose position you can modify. In addition to that, a dissecting microscope usually comes with too much magnification, which renders it useless for some electronics repair situations.

The point that we are trying to make is that it is a better idea to get a stereo microscope if repairing electronics is the purpose you want to use it for. A magnification of 0.5 to 3x is perfect, but just make sure that the unit is fitted with a ring light with variable controls.

He or she can observe numerous species, from exotic ones to small creatures living in your backyard.

You’d be surprised to see how fast children catch up and learn. Besides having obvious educational advantages, a microscope can also provide your kid with loads of fun, especially when there are so many things to look at through the magnifying glass.

Getting involved in a wonderful after school activity

In addition to discovering more about the microscopic world that is hidden from our naked eyes, getting a microscope will provide your 7-year-old kid with a productive and entertaining after school activity.

In this modern world that’s dominated by iPhones, computers, and television, it can be a true blessing to get your child to go outside to collect samples and then spend quality time in the company of his little newfound little friends. This would be in contrast to having him stuck in front of a computer for hours on end.

A microscope might actually help your child with school work as he could participate in a science project and bring his own contributions. This would surely stimulate creativity, boost confidence, as well as possibly improve overall attitude towards education.

 

Developing cognitive and motor skills

A microscope is surely not the easiest devices to learn on, especially when the child is young. However, these optical devices come with numerous benefits in terms of improving both cognitive and motor skills.

Your kid will have to learn to operate all those little dials, knobs, and buttons so he might get quite good at handling them. Of course, you can always help when things get complicated, and you can also go for a simpler microscope in the first place.

Another advantage to getting a microscope for your boy or girl is that he or she will also benefit from mental exercises by trying to identify species seen through the eyepieces, putting information together, looking at characteristics and comparing these with those of other species.

You may not realize it yet, but all of these fun ‘exercises’ could help immensely with educating your child and creating a path for a more certain future.

 

Studying to be a scientist

In the world of Silicon Valley companies, everyone wants to be an IT specialist. However, there are few who choose the path of a scientist. This can be a highly rewarding choice, especially given the hefty salaries scientists from top institutes receive.

According to plenty of studies, it can also be rewarding in terms of satisfaction with the job and with life in general. This is because it appears people with higher academic studies and accomplishments tend to be happier.

A microscope might just tip the balance of curiosity and help your child decide on a future career in life sciences. Many of us, grown-ups, regret not having made a choice earlier in our lives, and there’s a great advantage in providing your kid with the means to figure out what he or she would like to do when growing up.

Getting an easy-to-use device

If all the above may sound serious and complicated, you might be glad to learn that you can find plenty of microscope models that are quite easy to use, not to mention extremely fun. You probably shouldn’t actually think of a plastic toy microscope since it would add little to no real value.

Yet there are some instruments that are easy to set-up as well as use. Your child can learn to twist all those dials in no time. There are quite a few beginner microscope sets out there, ranging from the down-right simple to the more complex variants that should still be manageable even by a 7-year-old.

 

Enjoying a versatile device

One of the best things about microscopes nowadays is that they come with plenty of eyepieces, zoom options, lighting systems, adjustments, accessories, etc. What this means for you is that you have a wide range of options at your disposal so that you can make the right choice for your child.

You can get a normal glass microscope that comes with extra safety features, or a smaller and lighter plastic variant that you could upgrade later on, as your kid learns more.

There are also quite a few USB microscope cameras out there that could enable an easy connection to a laptop or computer so that your kid can record and review slides and experiments. This in addition to getting a much clearer view in the first place if you plug the microscope camera into a large screen.
