'[EE]: Piezo Gyro Bulk Buy Anyone?'

Is anyone intested in purchasing small quantities of Tokin Piezo Gyros for
(tentative) $35/ea. ? These are sensors used to sense rotation rate, and are
found in devices to stabilize video camera images and robots.

This is not for my profit (there isn't any!) but as a convenience for robot
and sensor enthusiasts. If I get enough interest, I'll set up a web form and
find a credit card processor. BTW got any recomendations?

These only detect rotation in one axis, and can only detect up to
90degrees per second, right?

So for a full 3 axis sensor I'd need 3 of them?

An article with a schematic:

That is correct, but in many applications you only need two to stabilize a
couple axis, or maybe even one. And you might want to buy a spare, from what
I've read from heli & airplane hobbyists, they can be fragile, if not shock
mounted in foam. But nothing could save it from my flying skillz (or lack
thereof)!

>and can only detect up to

Uh, thats what the datasheet specs. But the frequency response specs 100Hz
(flat at 10 Hz). Which means if your not trying to be agile like a bat, but
just trying to maintain stability, it may do? My crude DIY gyro (at
http://home.attbi.com/~scottxs/ ) detects rapid rates, but not low ones.
