Quick update from the land of PCB's!

Almost done with the circuit board!

Just the ATX connectors that needs salvaging from other boards and the power sockets that I've forgot (?) to order. Other than that, it should be ready for a check and conversion from old to new.

I'm especially proud of the big capacitor "UPS" for the ChipKit and the accompanying power sense circuit, meaning that the board will run for a few milliseconds after the power disappear, just long enough to save data to the EEPROM and shutdown things neatly. The watchdog will still kill any lingering solenoids, but it won't hurt to properly turn them off.

1) Almost fulled assembled. Sorry for potato quality picture!
