Just thought I'd share that my blueray diode from the Dr. Lava group buy just died. I built the 7805 circuit that Rog was using and set mine to 37ma with DX RCR123 batts. It lasted for about 5 minutes before it died and man was it beautiful! I feel very sad right now as I had just finished the housing for it. :'( It's a wonder it even worked in the first place, as I had a very hard time gettingi t pressed into the module. I've pressed tons of DVD reds into Aixiz modules, but this one gave me a fit. I bent the pins a little getting it pressed in. Not sure if it was that or my circuit was over driving it. Oh well, better luck next time I guess.
