nevermind... I just don't know how to use a lens... I just had to turn it to focus. I had it backwards in my head, turning it the wrong way.

Hello boys and girls. Here is my situation: - Driver built for 250mA, tested and functional - Laser diode purchased from DTR: Laser - Lens and housing: link With all of this put together, I cant even make a hole in a kleenex with black sharpie on it. The best I can do is SLOWLY shrink some...

Simple question, Can someone explain what those mean? I've searched around and can't seem to find any electrical answers. I am looking at this diode from DTR in particular: Diode Thanks!

Hello. I need some help finding a laser diode for a CNC project i'm working on. Originally, i intended to use a to-18 i took out of a DVD burner, but i accidentally bent off the positive pin... Could you point me in the direction of some reputable places that will sell me the diode ONLY? I am...

I got it. Nicked the sides but no biggie. I have to wait now (remember what I said about me being impatient) for my aixiz housing. This is all going to become a laser paint remover controlled by an arduino to make etching a more automated process.

It's alright i feel better now. I took out my frustration on the last remaining DVD burner in my apartment building and the LD works like a charm. Would you happen to have any tips on removing an LD from an ugly metal housing? It seems glued in...

I've never hated such a small object so much...

im powering it at 7.2V. Basically, I followed this guide

well shiite... I'm tapping the positive output of the circuit to the positive terminal on the LD... What you say makes sense. I hope that's not the case. At 250mA, my LD is hardly bright enough to illuminate the floor 1 foot below. Is that a sign that my LD is kaput?

Hey guys. I have made a DDL, i'll attach the picture further down. The problem I am having is, for starters, the lasers are either very weak, or don't work at all. The laser I purchased: LASER I know I have the circuit done correctly because I had to etch 4 times to get it right. Sometimes...
