Who among the boys did not dream in childhood to have a real combat laser, incinerating imaginary enemies at a distance? Time does not stand still. And although the boys have already grown up, and imaginary enemies have ceased to exist, today it is quite possible to make a laser out of a CD drive. The same one. Real and combat.
Instructions
Step 1
The first thing you need to do for this is to disassemble the CD-RW, DVD or BLU-RAY drive. It is also possible to make a laser from a CD drive, but it will not have all the necessary properties. In addition, it will not be visible, since cd lasers have infrared radiation. In other household devices, lasers are not powerful enough.
Step 2
Loosen all screws from the drive, remove the top cover from it, find and remove the diode from it. As the actuators vary in design, check the location in advance. The diode looks like two aligned small cylinders of different diameters. When viewed from the side, it looks like a schematic hat. He has three contacts. To make a laser out of the drive, you need the top - plus - and the middle - minus. The bottom can be removed or folded. Check the efficiency of the diode using two conventional AA batteries. The most important thing during the entire operation and during the further use of the laser is not to shine in the eyes under any circumstances. Otherwise, you can lose your sight.
Step 3
Chinese pointers are great as outer packaging of the laser. Having disassembled it, insert the diode from the drive. The only improvement you need is to connect two AA batteries to the pointer. You can also use a small flashlight as a housing and install a laser diode in it instead of a reflector. A laser like this can light matches, burn through paper and leave marks on plastic.
