The second prototype just recently came out. As opposed to the first protoype, this was made using Press-'n'-Peel blue and ironing the layout directly to the board. Although the ironing temperature is now the most critical step, this allows for a little finer trace width, as I still troubles getting 8-mil traces using UV exposure. The rest of the process is still the same.

This prototype now comes with an integrated PIC programmer, so that it shouldn't be necessary to remove the PIC when the firmware has been updated. In fact it should be possible to even program a completely different PIC in it. Unfortunately, at the moment, the project is current on-hold but I hope to be working on it soon.
