After watching many videos on youtube of people burning things with high power lasers, I wanted one.Those lasers can cost a lot of money though, something I don't have. So I made one, and in this instructable, I will show you how to make one for less than ten bucks. This is my first instructable, so if I did something wrong, please tell me. This laser outputs between 50-100 milliwatts(I think), and can burn electrical tape, light matches and melt thin plastic.I was messing around with this laser one day, and I shined it at a mirror, and the laser shined back in my eye for a second. I heard a popping sound and I couldn't see anything for a couple of minutes. Now, I was LUCKY that I did not get permanently blinded, but if I shined it a second longer I probably would have been. Now with that said, NEVER point a laser at another person, animals, or any other living thing.
Okay, Now lets make the laser.
Step 1: The Parts needed
Step 2: Get the diode
Remove all the screws on your DVD drive, take off the rails by removing the screws that hold it in place and take off the laser tray. There should be two diodes on the laser sled, one of them is infrared. You can test for the red diode by hooking the diode up to a 3 volt battery pack. Then remove the weak 5 mw laser module from the Aixiz housing and add the new laser diode from the DVD laser assembly. Solder 2 wires to the positive and negative of the laser diode according to the diagram.
