Has anyone done any design using gyros and PICs?

I am interested in using these sensors but have not found a good cost
effective source. I am also looking for low voltage sensors.

Currently I am looking at Murata and Tokin which manufacture the gyro
sensors, mainly used in video camera stabilization circuits and light micro
gyroscopes for RC helis.

Any help here would be extremely appreciated.

Been using a CROSSBOW angular rate sensor for some time.  Fairly small,
about 3/8" in diameter by 1" long.  Power (+5 VDC), Ground and signal out.
+/- about 500 deg/sec.  Our client buys them for us, so I don't know
price--but think it is reasonable in small quantities--definitely cheaper
than a mechanical gyro.

They are sensitive to shock and can take very permanent zero shifts if you
bang them too hard.

If anyone has a true gyro (mechanical or solid state) that will fit inside
a 1/2" diameter tube--I'm interested!

bae systems produce one you could get it inside a 1/4 inch tube

I know Acramax and CSM both use PICs in their heading hold
piezo gyros for r/c helicopters.

while i really do not know enough about them to say they are what you
are looking for, there is a company which makes a MEMS gyro. their
website is http://www.microsensors.com/ . size appears to be about 2.5
square mm for the gyro and 5 square mm for the interface.
