Wohoo my 5W laser arrived. At least it's something like 5W. It's 30W electrical, so in the ballpark probably. 12V only though, so I'll either need to shove an LM2596 in here or just use an external PSU. Probably the latter. No-name driver IC, but there's a pin labelled 12V and a pin labelled PWM so it should be pretty forward to wire up.

I'll probably also mount the MCU externally this time. Gotta figure out a better way of PWMing it with both the g-code S value and the minimal pilot light intensity, this time using a MOSFET or buffer or whatever in order to prevent from sending a PWM signal when there's no 12V. Assuming I can even get a minimal amount of light out of this thing.
