I'm not using any capacitors. is 250mA too much? people seem to agree that 200-250 is the ideal range. according to the lm317 calculator you posted (ty btw) my setup is correct for 250mA and removing one of the [parallel] 10-ohm resistors will make it correct for 125mA

@leodahsan i haven't done anything yet - kind of sick... :( i suppose the next thing to do would be remove one of the 10-ohm resistors in parallel right now, and failing that, hook up a new diode to my circuit with the lm317

I used a 15 watt iron. although i have fried things with a soldering iron, that didn't kill the diode. will hooking a diode (JUST a diode) up to 3V (i.e. 2 AAs) unregulated current fry it?

Really? Hmm before I desolder those connections (i did such a good job! haha) did you try using the diode without the LM317 driver? Because I did and it as well was very dim if you found the same thing, then we certainly have the same problem, so the same solution should work as well :)

Hi guys the past few weeks I've been building a red 250mw laser... I used some 16x dvd burner as well as the standard aixiz module. I also made this [http://www.youtube.com/watch?v=2Rjlf7gnXms] laser driver (using 5 ohms of resistance [2 10 ohm resistors in parallel]). It works, but it's...
