Hi, I've been looking around with not much luck trying to find some schematic for a driver which would have almost zero voltage drop. Using LM317 based driver will require power supply of at least 5V. However if I were to use one lion battery with 3.7 or two 1.5 batteries, I am out of luck here...

Well, thanks, lol. I soldered those two wires, so yes, red is positive. And I removed the crystal as well. I was wondering how does the diode look like out of the case. It does not look like this one, however it is quite similar: I guess it is pressed in so I would need to press on that...

Btw. do you know what laser diode it is? It doesn't seem like a regular open can type I saw on pictures.. And... how do I get it out?

Re: How I measured my laser diode for few $ Yea, you're probably right. I forgot that safety diode, so 0.7+2.5+2... ~6V should be enough then (depends on type of laser diode). I used 12V anyway because I needed 0-5V on Ra :-).

Hi everyone. First - I am new here and I am new to lasers, however I learned a lot from this project and I think it might be benefitial to some of you so I share it here. I got a new 8$ 5 mW green laser from DX and because I'm quite curious, I decided to open it. Well, no surprise - case, 808nm...
