In my previous life (working for various companies) I always wanted to
know what projects had done wrong rather than having to listen to the
hurrah stories of what they did right, so I'll share my (PIC) bloopers
with you.

today:
I am coding a gravity sensor (ADXL + 12F675). Previously the gravity PCB
contained just the ADXL, but the wires bundle from the gravity sensor to
the motor controller also contains the motor wires, so that gave lots of
interference (the ADXL output is ~ 32k impedance), so I put a PIC on the
sensor print so it can send the measurement in digital format.

blooper: after 1 hour of trying to get the A/D to read something else
than 000 I took a closer look at the PIC that I soldered onto the PCB a
few weeks ago. It is a 12F629 ....
