Manufacturing some prototype PCBs *mountain man style* in order to interface two different electronic modules together and clean up the wiring!

In college I used to be obsessed with designing PCBs in this way. It is fun to make a design which only requires a single of layer of copper.

Part 1: Print the circuit onto toner transfer paper.

Part 2: Transfer the ink from the paper onto the copper board, using a hot iron.

Part 3: Etch the copper board using Ferric Chloride

Part 4: Start soldering... Use what you have on hand and make it work!

Part 5: All the modules are soldered into place. It works!

Part 6: Looking good for what it is. Will refine the design a bit more, and then decide whether it is worth sending the board off to be professionally manufactured.
