Make your own PCB (printed circuit board)

http://www.amazon.com/Copper-PC-Board-Single-Sided/dp/B000P7ALZC

clean/scrub the copper side of the PC board with steel wool
 do NOT touch  it with your fingers
   as the oil from your fingers will prevent the "resist" (aka marker/printer ink)

then black magic marker a design on cheap copper pc board

or you can print laser ink onto thin plastic clear sheets
 then transfer it PCB design onto the board

  with a clothes standard iron (no steam)

sponge/rub on Ferric Chloride to the PC board until it eats the copper
  and you see the fiberglass backing

wash and dry it

Cheap Micro Drill-bits are helpful when drilling holes

Etchant - HomeMade / ReUsable! (Safer/Env Friendly)

1 part   Hydrochloric/muriatic/pool acid $5/gal    ...instead of Ferric Chloride Liquid
  +
2 parts  Hydrogen Peroxide

...Put in Non-Metalic container...
     keep it away from metal (as it can "eat" stainless-steel kitchen sink coating!)

Put in PCB to "etch" it super-fast! (<2minutes)
  swirl it around a little as it etches.

Etchant gets greener (creating cupric chloride)
 as it eats the copper. (good news)

the cupric chloride will be doing most of the etching
 (instead of requiring disposal).

You can reuse it
 ...the green color will deepen
