DIY: How to build A High Powered Burning Laser pointer

Edit: I removed this video because the info in here isn't helpful and the youtube community has a 99% idiot rate.Don't want to build one? Buy a 200mW one for $44 here http://www.dealextreme.com/det... you really want to build a laser, please don't use this tutorial. I made this video when I was younger and I didn't know much about lasers. I will have a much better and easier tutorial up in a month or so if you can wait. Until then check out laserpointerforums.com for some great tips/tutorials on building lasers.If you are going to use this tutorial anyway, the circuit used in this video is a BARE MINIMUM. Although the one I made in this video still works fine to this day, you will probably want to add a small capacitor (anything over 10v 16uf is fine)in parallel with the diode to even out any voltage spikes from the battery. To build a well regulated circuit check out www.laserpointerforums.com for some great, easy to build, current and voltage regulated circuits for lasers. One thing to note is the prices of the diodes have jumped from $13 to $19.50 but you can buy the diodes off of sales.stonetek.orgIf you need more help you can find me and a bunch of other people that can help you on Laser Pointer Forums and Spectraforums! http://www.laserpointerforums.... http://www.spectraforum.com In this video I show you how to build a homemade high powered burning laser. Parts:You can get 100ohm potentiometers off ebay for pretty cheapYou can get you switch and battery holders at any radioshackYou can get your laser diodes at laserpointerforums.com for less than half of the price of pulling them from a DVD burner (and a heck of a lot easier)You can get AixiZ modules from Ebay Seller aixiz_lasersA few tips-DO NOT LET ANYTHING SHORT!-When you have turned the pot so the brightness turns high, don't even think about turning it more to make it more powerful. If you do that the power will go from 100mW+ to .1mW and your diode will be screwed-buy more than one diode cause they can break by simply touching them sometimes, too much current to the diode or a ton of other things so you will be safe buying more, and if you have extras build more modules and sell them to your friends for even more fun! (go ahead and charge $100 for them so you can be rich)-Buy goggles for these things! Goggles cost around $40 and are easily worth it, your eyes are worth more than $40 and if you get hit in the eye by this thing without goggles on, you're screwed.
