Heres my lm317 test driver. Plus I want to test adding a picture. It seems to work just fine. Right now I have it set to put out about 250ma max. So now I know my DVD reclaimed diode is working, I'm on my way. total cost 0$ Got all parts from old electronics took more time but it's free. I like free
Well done...
You're on your way. Don't forget to build yourself
a Dummy Test Load and don't forget to short out
the output cap to discharge it before connecting
your Laser Diode..
