Homebrew PCBs

I've thought about PCB etching with EDM, I figured it would work ok, but
be a bit slow.

People mill PCBs, that's slow & noisy!  At least EDM is quiet.

Considering the small amount of material you need to remove, the results
might surprise you.  After all, electricity is a good way of removing
metal.  Most of us have screwdrivers or probes with bits missing (usually
after testing capacitors!), that's a good bit of metal removed in a short
time.

I'd be interested in the final result (quality, speed, minimum trace etc),
but I doubt I'll ever make PCBs this way, but I'm happy to keep it in
mind.  The info could come in handy for other projects, etching
nameplates, etc.
