The Vector 2X has a calibration feature wherein you start a cal program,
turn it 180 deg on its vertical axis, and finish the calibration program.
That takes of metal fixed relative to the compass. Twirling blades and
reciprocating pistons may be moving so fast they average out, since the
readings are at 5 Hz. I'm stuck right now integrating mine into a 68HC11
processor, look at ray butt's Tcomp computer. Look for Tcomp on the Web,
it's about $70, not near as nice as the Handyboard. However, it is based
on the E processor, allowing 4 input capture lines, which I've gotta have.
