Guess I'll be the first to comment. Glad you got a working 445nm laser! I'm sure you are aware of their dangers, but they are one hell of a beautiful color

How well is that heatsink going for you? Stays prity cool?

well the heat sink stays pretty low on temp , even after 45m , 1 hour it's not much more then 85 - 96 F , but i still run @ 660 700mA in these pics
I ran it @ 900mA today 3.6 V , time to add a lil coolfan ( later ) but im pleased with this cheap laser cheers!

Cool build Does the head of the aixiz module keep cool? or does it have more temperature than the heatsink? seems like there were no good contact between module & heatsink... if you have used silicone like paste to fix it to the heatsink, remember this compounds haven't a good thermal conductivity.
