Lpc-815 Lab build

[RandomDigit]

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!

there is but i dont know how...

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

Does it also burn shirts?

There is a way - you can use the yt tag.

There is a thread dedicated to answering that very question here -

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.

 

[Gryphon]

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

 

[RandomDigit]

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

 

[Gryphon]

^ alright, that should give you a better sense of whats going on

Nice build, I see this is a video response to one of my videos!

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.
