Laser from DVD drive by own hands

Many in their childhood had laser pointers, which could be purchased at toy stores. But with the development of modern technologies, it became possible to create such a laser from a DVD drive with your own hands. To do this, you only need a faulty DVD drive (it is important that the LED itself remains working), a screwdriver and a soldering iron.

It should be remembered that it is better to use a non-working DVD to create a laser! This is due to the fact that after disassembling and removing the LED, it breaks down. Do not forget that such a laser from the drive is much more powerful than an ordinary pointer and can cause irreparable harm to health, so you never need to direct the beam to a person or an animal. When the beam of such a device is aimed at the human eye, the retina is burned, and a person can partially or completely lose sight.

So, let's create a laser from a DVD drive with our own hands. To do this, carefully unscrew the bolts on the rear of the housing to get to the LED of the future laser. Under the cover is a node that carries the carriage drive. In order to extract it, you need to unscrew the screws and turn off all loops. Then remove the carriage.

Now you need to disassemble it, for which you need to unscrew a lot of screws. Next, two LEDs will be detected. One of them is infrared, it is responsible for reading the information from the disk. Need red, with the help of which the information is burned to disk. A printed circuit board will be attached to the red LED. To disable it, you must use a soldering iron. To check the operation of the diode, it is enough to connect two finger batteries to it, but it is important to take into account their polarity. Remember that the laser diode is fragile, so you need to be very careful with it.

Next you need to buy any laser pointer. When creating a laser from a DVD drive with your own hands, use it as a "donor" for the case. After buying, you need to carefully untwist the pointer in two parts and remove the laser diode from the top half . To do this, you can use a knife. It is important to do everything neatly, because the diode can be damaged. Use a small screwdriver to select the radiator. Using hot glue, install a new LED in the body. And that it is firmly established, you can use pliers, pressing them on the edges of the diode.

The laser from the DVD drive is almost ready by hand. Before you start it, you need to check whether the polarity is correctly defined. Now you can safely plug in the power. After initial start-up, you may need to adjust the focus. Then you can set a pointer to the flashlight and connect AA batteries. Do not forget that the laser can burn different objects, so you need to remove the plexiglass from the scatterer.

A well-tuned laser from the DVD drive can not only burn paper or set fire to matches, but also leave a trace on the plexiglass, blast the balls (it is better that they are black) and leave visible traces on the plastic. If you install a diode in the head of the plotter, you can perform engraving on the plexiglas.
