[SGVHAK] Pi + DVD Laser CNC engraving

[James McDuffie]

That is actually the article I had read before discussing it last
Saturday. I did order some of the motor drivers after reading it, but I
do not have any DVD drives to salvage lasers and steppers from. Laser
diodes from ebay in the 200 mW range seem to be running around an
average price of $25, although I have seen some as low as ~$12. If
anyone builds this I highly suggest buying laser protective goggles as
well. Also as the article points out, its better to get a visible laser
instead of an IR one because you can actually see the beam.

I remember James wondering if this would be possible. Looks like a
Caltech grad already tried it:
