I'd toyed around with the idea of creating a piezo gyro also. This was
almost a year ago, Murata was not willing to give me 1 or 2 sensors, so I
bought one of those gyro mice and stripped the sensor from that, I ran into
problems with thermal drift and overall sensor stability and gave up on the
design.

I'll try to dig up the old code that I had. Maybe we can revive this
project

Oyvind;

I don't have the time for writing code, but if you point me to data on the
optical
gyro concept or whatever it is, I can contribute to the hardware portion of
the
design.  Sounds too cool.
