Hey LPF... I need to vent after killing a few more lasers.
So I'm building a sweet RGB array with custom everything - drivers (FML style with effects and everything), heat sinks, fans, variable power for all the colors with the 445 pushing 1.5W.
I am on a time crunch trying to get it done for a laser show tomorrow and I lost all my red lasers. I killed one with a rough extraction, and the other two died somehow in my circuit. The circuit worked PERFECTLY for 2 days while I was machining my heat sinks and adjustable mounts, then when I tried to mount everything, it stopped working... and killed my lasers. My green/445 may have survived, but at least the red died. So I proceded to remove a red module from a pocket RGV that I had built earlier and stripped my driver down to the basic Lm317 base. I short the remove power, short caps, and plug it in... and it kills it! No changes from my original working circuit and what do I get, 3 dead diodes!!! ARGGGG.
I guess something must have changed in my circuit, because lasers don't usually spontaneously die like that, but it's still frustrating and I needed to vent.
So over my year or so building lasers, I think I have killed 6 LPC diodes... and me see... only 1 non-red diode. Granted a few of the reds' deaths were due to really stupid mistakes that I learned from (shorting caps, removing batteries, etc). But still.... Are these diodes unusually fragile? I have several green modules, a 445, and several blu-ray lasers and all have held up marvelously.
Ahhhh it's just so disappointing to lose a needed part the night before I want to test my new laser show set up.
Thanks for listening. I just needed to vent.
