The level of miniaturization of modern electronics is high. That is why it becomes necessary to use special tools designed to simplify work with small details. An example of such tools is a microscope that allows you to solder yourself. Find out how easy it is to make it yourself in this article.
Materials and tools needed
Many experts tend to argue that in order to independently make such a microscope, it is better to use a USB device, since it allows you to provide the necessary focal length. However, in order to implement such a project, some preparatory work is required, which simplifies the process of assembling the device.
At the same time, the most primitive and inexpensive network camera can be used as the basis for soldering such a microscope. For example, it can be an A4Tech network camera. The only requirement for this is the presence of a working pixel array.
And also, before starting the assembly of the product, it is necessary to purchase elements that provide the necessary level of efficiency with such a device. We are talking here about important backlight elements for working with such a product, which can be taken from any old disassembled mechanism.
In addition, it is necessary to prepare in advance a massive object that will serve as a support. For example, it can be a frame of a laboratory hardness tester, which can be purchased at any nearby scrap collection point.
You will also need to prepare a “hand” on which such a camera will be mounted. For this purpose, a piece of rectangular pipe made of a material such as aluminum is perfect. You can not do without a corner bracket, which simplifies the task of quickly turning the camera.
How to do it yourself?
Here are the instructions for doing:
- Disassemble the webcam as you won’t need the housing.
- If the microphone is detached, it is recommended to remove it. The cable going to the board through the back cover of the case must be disconnected and then soldered again. Another option is to completely break the existing shell.
- The plate located near the lens is equipped with an LED. It may interfere if a microscope is used. For this reason, you need to desolder it and then check the available camera performance. This will ensure that you don’t accidentally desolder the excess.
- After that, it is necessary to unscrew the standard camera lens. A similar design can be replaced with a lens from a larger camera. But first, it is recommended to find out at what specific distance from the used matrix it is better to install it. To cope with this task will help to carry out practical tests with a completely closed opening.
- It is recommended to install the lens on the frame of any hardness tester or on the tube. After installation, you need to turn on the camera to check its operation. During testing, it is recommended to record parameters such as the distance between the working chamber and the lens used and the minimum distance between the object under study and the lens.
- Having found out the optimal distance, you can start working on the body of such a microscope. It is convenient to print it on a printer. For printing, you can pre-make a support intended for the artboard. Well, when such a bracket has a mounting hole.
- Also, it is recommended to print the part as a small diffuser. It is also desirable to make guides designed for adjustment.
Finally, from a pre-prepared rectangular pipe, you need to make a hand.
It is recommended that the legs of the rack be made in such a way that the mat intended for welding is placed between them.
Thus, a microscope designed for welding parts can be easily and quickly made independently if the necessary tools are at hand and the user has the skills to work with them. If the necessary skills are not there, it is not a problem. In this case, the tips from the article will come in handy. Using them, you can easily cope with the task of making a microscope yourself.
