Step 1: Materials
Strip of 2-sided copper-clad board. The size of this will depend on the size of your layout.
Paper. You don't need anything fancy. Just get basic gloss photo paper.
Tape. Scotch tape works fine.
Sponge. I use a potter's sponge (available cheaply at art supply stores), but any type of sponge will work.
Ferric Chloride. Available at most Radio Shacks.
Light Box. Optional, but very useful. If you don't have one, you can make one easily, or use a window on a sunny day.
Drill Press. You really don't want to use a hand held drill.
#60 Drill Bit.
Acetone. This will dissolve toner in a hurry.
Scotch Brite Pad. Buy a lot of these. They wear out.
Rubber Gloves. You really don't want to get ferric chloride on your skin.
Safety Glasses. Need I say more?
