Wow, sweet looking build. You must be getting some pretty insane runtimes with that much heat sinking and battery power.

As far as I know, I don’t think there are any manufacturer data sheets available for m140 diodes but they are 445nm and DTR recommends a max current of 1.8 amps. That should get you 2w+ with a g2.

Just search “m140” in lpf and you should be able to find a ton of info.

Hi,
That projector has the A140 and M140 diodes in it 24 total . the M140's will have a stamp between the pins and the A140's will not.6374263743

I haven't put a laser diode in a project box in a long time. Thanks for the walk down memory lane.
