Well, I was interested in making my own built lasers; (Mainly because of the recent Ban of all imports of lasers over 1mw to Australia, which totally sucks; so much for buying the nice 250mW laser from eBay US). So a friend of mine sent me the link to several sites that stock and sell parts (ie: housing, diodes, heatsinks, etc) - and I found some easy tutorials to make a nice kick ass laser from a 16x DVD Burner diode; then I came across the "MagLite Torch" laser hack, which blew my mind, which just got me thinking of making my own, which I have yet to do and can't wait!
Well the same friend I know sent me a link to this forum, and so far what I've read is Kick ASS.
Great forum all up!
