Hey everyone kind of new to this forum so thought I would share one of my recent projects. This is my lab style Lpc-815 LASER. It took me about a day to build as I used scrap parts to build it. The driver is a homemade lm317 driver circuit set at 420mAh. The heatsink is from an old computer and everything else is out of my scrap bin. anyways here is a video about it. hope you enjoy! :)

Very nice laser, I've never seen a finned heatsink used like that befor :thinking: there dosn't seem to be much contact of aluminum with the Aixiz module so I wouldn't count on it cooling your module much. keep us posted as to how long it lasts ;) +1 for you for your first laser :D

Thanks for the replies everyone! Surprisingly the heatsink does work pretty well I've had some pretty long duty cycles and this thing hasn't even gotten warm.

remember, even though the heatsink hasn't gotten warm doesn't mean the diode hasn't
it just means that the heat hasn't been transmitted through yet

Yeah I know I'm feeling the front part of the module that sticks out a bit for a better sense of the diodes actual heat

I built a laser with a very similar design that has run for hours on end without problem, the fins suck away enough of the heat to avoid problems.
