Homebrew PCBs

1) I use direct toner to hot foil. I use HP LaserJet 6L, works at 
either 300 or 600 dpi.

2)Flat hot press to PCB. I was lucky enough to have one around, works 
much better than an iron. Better, more consitant results.

3)etch in ferric chloride. I have Ammonium Persulphate, but I want to 
finish using all the Ferric fist (its taking a long time).

I get 10 thou lines (10mil) without problem. Large surfaces give me a 
bit of problem, but easy to fix. I could probably get 5mils, I just 
don't need it, yet.

Look for my PCP photo (scan) in the "Files" folder, maybe today.
