I'm new to all this stuff but I wanna build a laser from DVD burner.
I heard that I definitely need a driverboard (contrary to most video instructions) or my diode will die in a matter of seconds.
I'd like to make a fairly long lasting laser, one that doesn't die after a week or so.
So I need a good 3V driver board which drives around 200 mA. However, I wouldn't like to make my own driverboard.
Can you recommend me some flashlight or so apart from Dorcy (because I cannot buy one so easily), preferably from DX. I would also prefer powering it with AA or AAA batteries.
I know I'm a bit picky, but I'd be grateful if someone could help me out.
