Hey guys, i was wondering if you could help me determine if the driver I use is defective.
Story:
I bought 3 laser diodes from diy-lasers.com and they sent me 5 and charged me for the 3 then I bought a little 4 dollar driver. So there was a chance that there could be problems. Anyway I pressed the diode in the aixiz housing and when i tried to determine the current of driver with a crappy homemade dummy load(it did work on a "once to be" green laser's driver). I got nothing on my multimeter. So I tried messing with it but still no results. Then, out of the idea that i'll have 4 diodes left i soldered it on. Then I turned the power on and no LED... but very dim. So i cranked the pot up and then it flashed brightly then... poof LED'ed.:crackup: So then took the now LED out of the housing and did the stuff said above up until the driver part. This time I kept the pot all the down until it stoppped then I went probing. The laser diode flashed extremely bright and made me see spots for 5 minutes. I dropped the screw driver making me loose my probing spot. This time with the lens on, I probed around for the same spot... found it. I had to bridge the 7 and 8 pin on the IC. Still no LED up till now. :beer: I power it with 2 AA's
