Instructions
Paint PCB with a black primer. Laser etch the designs. (a few times is better. Normally this is not needed. Due to the small chip this is a good idea) Then place board in ferric chloride or rub the ferric chloride on the board directly. (This is what I do).
Remove and have fun. Oh and I used a header vs the CDROM cable that it called for. I want to test this out on the contraptor stuff to see how accurate I can get :) so no need for that specific port.
