Homebrew PCBs

Can you provide a price info for the ir laser diode?
I'm thinking of converting my Epson printer to just a plotter.

| I have used a cheap infra-red, I can use to melt most any thin black
| material, lines so thin you need a 10x lens to see them.  With a cnc, I
| can rasotize an image with it.  A co-2 laser is LOTS more powerful and
| really expensive, not something someone can buy to toy around with
| (unless you have $300 - $1,200 ebay prices to throw around).
|
| The IR laser diodes are strong enough to melt, smolder thin black
| materials.  I can etch a logo in black plastic within a square 1/4 inch!
|
| I just cant figure out what to use to melt or solidify as a resist onto
| a copper board.  Spray paint is a new idea, if I can manage to find a
| paint that is thin enough that will vaporize with the diode I am
| using.  And also thought about using printer toner (just the black
| powder) - to somehow coat the entire board, the IR diode could also
| melt and fuse the toner right to the copper, but that stuff is very
| messy!
