Homebrew PCBs

Hi,
   Nobody liked my light on a plotter idea. I was told the
light source would have to move too slow. The board would take
way to long. Ok, I use Mechanical Etching bits myself. But what
if you coated the whole board with resist. Then you put a sharp
point in the plotter. Have the plotter do isolation paths. Then
the board goes to the acid.
