How to make a mouse for a computer

A computer mouse is an integral part of any desktop PC, but it is also used with laptops. After all, many users prefer it to the touch panel, which is available on similar models. This is due to the extreme ease of use of the mouse and intuitive functionality.

There are a huge number of models on the modern market, and every year more and more new, more improved ones appear. But their prices also change. What to do if your old mouse is broken, but you don’t want to buy a new one for financial or any other reasons? How to carry out independent repairs or even make a new mouse with your own hands? You will learn about all this in this article.

Common computer mouse problems

First, let's look at possible problems with the mouse that owners of this device often encounter. Not only the choice of type of repair, but also the final result will depend on how correctly you determine the cause of the problem.

IMPORTANT! Carry out a thorough inspection of the device to make sure that the breakdown is in the exact part where you think it is.If you carry out incorrect repairs, you may not only achieve no result, but also permanently break the mouse. That is why it is also important to study the sequence of all actions in advance.

There are several main types of breakdowns, which in most cases occur among ordinary users of office mice. Eliminating them is not so difficult, so even a beginner who does not have special skills and knowledge in the field of technology can cope with the task if he spends a little time and effort.

The cause of the problem may be:

• cable break;
• button failure;
• wheel breakage.

You can try to disassemble the mouse and carry out the repairs yourself. But for this it is important to understand the internal structure and principle of operation of the mouse. All the necessary information can be easily found on the Internet, so there is no need to worry about a lack of knowledge.

How to repair a computer mouse

Each of the above reasons requires special repairs. But in any case, the mouse will have to be disassembled. How to do this correctly?

How to disassemble a mouse

In order to gain access to the internal structure of the mouse, you need to unscrew the mounting screws that are located on the bottom side. In most cases it is one screw.

Sometimes it can be difficult to find - manufacturers may cover the screws with stickers or bearings. Feel the entire surface - in place of the screw there will definitely be a deflection in the shape of a circle.

If in the case of a sticker everything is simple, then removing the thrust bearings can be very difficult. You will need a knife, which should be used to carefully remove the part, which must be returned later - without bearings the device will move on the surface much worse.

After this, you need to disconnect the mouse and remove the top part with the buttons. Then remove the board. In some models it can be screwed on.

IMPORTANT! Try not to touch the optical parts with your hands; if marks remain on them, you must wipe them thoroughly. Otherwise, the mouse may perform worse than before.

Wire repair

Most often, a break occurs at the base due to the fact that the mouse constantly moves along the surface. The repair is simple: you need to find the break point and use wire cutters to “bite off” the cable a few centimeters above and below this place. After this, the parts need to be soldered.

Don't forget to insulate them with duct tape or tape. Heat shrink tubing will also work. Now you need to strengthen the cable - to do this, use glue and glue the wire either to the body or to the mouse board.

Troubleshooting the wheel

If, when scrolling the page, the image jumps up and down, you need to open the encoder. After this, remove dust particles from the contacts, clean them thoroughly and reassemble the part.

Otherwise, you may need to tighten the fastening.

If the wheel axle is mechanically damaged, you need to insert a new one. The material you can use is either an allen key or a self-tapping screw of the required size. The material must be ground and inserted into the device instead of the old axle.

Button repair

First of all, pay attention to the “symptoms” of the malfunction. If the button takes a long time to return to its previous state after pressing, there is a grinding noise or it is difficult to press, then the reason may be simple contamination of the plate. You just need to clean the parts. This can be done using an old toothbrush or a cotton swab.It is best to use alcohol.

If the button does not always work, then you need to disassemble the device and inspect the contacts. Most likely, you will need to solder each of them. There may be a crack at the location of the problem button.

When the button does not press at all or does not return to its previous position, you need to replace it. Another one can be purchased at any specialized store. But if you don’t want to do this for financial or any other reasons, try swapping the broken button with the one you don’t use - for example, rarely does anyone press the button in the middle.

How to make a PC mouse with your own hands

If you have an old mouse case and a few available tools, you can assemble it yourself.

As a wheel, use any gear that will scroll. You also need to find parts that will be used as buttons. These parts must be connected to each other using a cut of copper wire.

Then find two air cylinders that will rest on the rest of the body. Place a metal plate on top - it can be removed from the watch. The cylinders must be soldered. The next step is to build a strong lower body.

IMPORTANT! Do not remove the optics from the bottom under any circumstances. Without it, the mouse will not be able to work.

Now you know how to repair a computer mouse yourself and how to disassemble it. In addition, now you have information on how to make a device yourself based on the old one. This way you can save a lot on purchasing a new mouse and use your computer comfortably.
