HomelinessDo it yourself

Let's make a laser by ourselves

To assemble a laser at home with one's own hands into a device that allows cutting various materials is quite simple. To do this, we need a laser pointer MiniMag, an AixiZ module and a radiator from a faulty DVD-ROM (defective may be the mechanical part, but not the laser itself).

It must be taken into account that the laser beam is quite dangerous and it is highly undesirable to direct it to a person or an animal. Do not play with him and give fun to children. Be sane, be aware of the potential danger of the device. A laser for cutting metal with your own hands from improvised tools is difficult to do, but there are other materials with which the assembled product can easily cope.

To work, you need a laser from DVD-ROM, produced by LG, while keeping in mind that different drives have diodes that differ in their power. Produced by other manufacturers may not be suitable (for example, drives manufactured by Samsung, will not work, since the diode has an unobstructed design, the crystal itself does not have protection against mechanical damage). If there is no home for a faulty DVD drive, you can buy the radiating diode in a store or on the market, as well as a broken drive from a junkeeper or a repair shop.

Remove the screws holding the drive cover and remove it. After removing the fixing screws of the movable carriage assembly, it is necessary to release the two guide elements and get it out. Incidentally, disconnect the existing wiring. Further work begins with unscrewing the screws, which are sufficiently large. After disconnecting the cables, there are 2 diodes: infrared, used for reading, and a diode that burns the disc during recording. We need exactly the one whose hallmark is a fixed electronic card. With a soldering iron, carefully remove the three screws securing the PCB. The diode can be checked by connecting two finger batteries. If it is functional, then carefully remove it from the case, taking care.

Remove the sticker on the AixiZ case and take it apart. Inside the upper body there is a low-power diode, which we will change. With light knives using a knife, remove it and use a small screwdriver to knock out the radiator. With a small amount of hot melt, lubricate the edges of the diode and carefully insert it into the AixiZ case. To avoid bulging with the use of flat-nose pliers, you need to press a little on the edges of the diode until you reach the desired result.

Next, it is necessary to solder the existing two barbels to the corresponding diode supply terminals and install the assembled emitter directly into the MiniMag. Disassemble it and enlarge using a round file or drill reflector. After checking the polarity of the connections, carefully place your laser at the top of the MiniMag instead of the old radiator. After assembling the upper part of the body, you need to fix the reflector without installing a plastic lens.

Be sure to check the polarity of the diode leads before installing and connecting the power supply! In addition, when adjusting beam focusing, it may be necessary to reduce the wires.

Install the batteries and use. By making a laser with your own hands, try different options for its possible application. It easily burns paper sheets, balloons burst when they hit them.

Collected from improvised means, it is not powerful enough, but it's a gas laser. With your own hands, try its possibilities to cut household plastic products. Correctly focusing the laser beam and advancing it along the material, first get deep enough furrows, and if you continue, then the burnt areas.

Accurately attach the laser with your own hands, without using any tools on the plotter head, and now you can engrave on plexiglass or plastic various images and inscriptions. Show your imagination, try your skills and abilities.

In conclusion, I once again want to recall the observance of precautionary measures. Do not use your device for hooligan reasons or to test the sensitivity of the skin to hit the beam. You made a laser with your own hands and will be responsible for it yourself.
