I know, pretty crappy to have been a member for two years, and first now have completed my first real build (except a LPC in an aixiz that died within 2 min) 
Anyways, it's nothing special, just an XJ-A130 @ 850 mA in a Jayrob 18650 kit.
It has a copper heatsink.
The first time I assembled it and turned it on, nothing happened. Needless to say, I nearly shit my pants. So I disassembled it and hooked the diode up to a spare rkcstr, while repeating "Oh shit, oh shit, oh shit" in panic.
I saw a faint blue light, as if the diode was LED'd, and I nearly shit my pants for the second time. Then I turned the pot and realised it was just below treshold current. The diode was fine. Phew!
So I wondered what was wrong with the jayrob kit. And then I tested the battery, and it read 0V. Ah.
So I charged the battery and assembled the laser again, and this time it worked perfectly.
I don't have a (powerful enough) LPM but it should be outputting close to 800mW. The color is a beautiful bright blue. The beam is clearly visible even in lit rooms, I don't have much to compare it with, but it's definately not too far behind my 200mW green module in brightness.
I was hoping for a bit better burning abilities, but oh well. It burns much better than any other laser I own, of course. But I couldn't light a match the hard way, or burn paper very well. It burns holes through both, but it doesn't ignite it :/
Here's some pictures (barely any smoke) :
PS: Unfortunately I didn't build this for myself, but for some other guy from Norway. I'm going to forward the laser tomorrow.

anyway, what have you heard about those olike goggles? i have some coming in soon, is there a review?
