I hope this isn't too boring, but I enjoy building these things, just thought someone might want to see another person's approach to building a laser from the GB diodes and simple parts. After building one laser in a Radio Shack battery holder, I thought it was a pretty good host - easier than...

Well, I had this diode from a DVD burner that has a miserable beam (another post), and didn't want to waste a good flashlight to mount it in. I'll put my good diodes from SenKat in a suitable enclosure when I have time. So, I found a 2AA plastic battery case at Radio Shack and thought it may...

I had a return of a defective DVD writer, an LG GSA-H42N. It had a standard closed LD with a window. I put it in a Aixiz holder with a glass lens and the resulting beam was horrible - a line with 2 dots as can be seen in the rather poor photo. I tried a different lens, cleaned the LD window with...

I put together a DVD writer diode, Aixiz brass holder and a constant current power supply (LM317) like most everyone here has. The momentary button supplies 200mA to the diode, the slide switch provides 100mA for aligning, longer running, etc., when I don't need to burn something. Works great...
