Population: complete, Fault chasing: still in high speed pursuit.

As can be seen in the picture below i have finished populating the first board.
(ignore the soldering blocks behind, my bench is currently covered with [1] jewellery making stuff and vibrator making stuff)
faults so far found:
Power transistor not connected to the correct pin of uC
Tracks to voltage regulator end before they arrive
Opamps wired up back to front
pressure transducer acting as a theremin so something is wired up a bit wrong.
Always happens though, first PCB version never works. Looks quite professional though!
