This is fig 2.57 from EMRFD. The pads for the circuit were cut using a modified brad point bit. The pads can be cut directly into the PCB material with an ordinary hand drill making for very fast and spontaneous building. I have a YouTube video that shows how to do this at http://youtu.be/ErJWhwNKnEI
