Homebrew PCBs

If I were to try and go this route, I'd suggest going with a BluRay laser if
you could, or at a minimum a drive that supports LightScribe.  (more power)

I've heard that the diode lasers in consumer DVD-R drives can pop
balloons...I'm not an expert, but it seems feasible that it could evaporate
a thin layer of paint with a slow enough pass.

In fact, it'd already be mounted on a single axis of movement with
absolutely overkill resolution, with a fairly sophisticated dynamically
adjustable lens assembly.  Hmmm...
