Thanks Gadget! this was actually reeeeaaaly informative. :beer: As a side note, what would 0 Bias be? I know that the P3 driver has a 0 bias pot along with a voltage and current one. I added an additional battery but got pretty much the same results, leading me to believe the diode is toast...

Yeah I need to throw another AA into the mix. the driver's probably broken, its bypassing the pot and resistors entirely so that'll need to be fixed.... Is there a way to read the voltage (or some other reading) when the diode is connected and running? maybe if I hooked up the meter leads to...

Hey guys, To answer some of your questions, yes specter, I was using a typical 9v battery, and yeah it seems pretty dead. I'll have to pick up some $2 laser pointers and get some more diodes lol. I took your advice and soldered the driver and the diode all together. When i turned it on I could...

Hey guys, thanks for the replies! Last night I upped the power supply, I had a 9v that read as around 7.1V so it seemed ideal, but I still got nothing. thats what makes me thing I'm doing something obviously wrong since I get no light from diodes no matter how much power I pump into them. So...

Hey Guys! I've been trying to get my first laser set up; it’s a 5mw 650nm diode with a DDL driver. I've been reading around for what best to do, The diodes came from Aixiz. I got them mostly because they were cheap and I could practice soldering on them once I got the driver going. 5mw 650nm...
