You can get the yaw rate sensors from Future that were discussed by Chris Hibner.
See this thread

There are two models, the ADXRS150 and the ADXRS300. The number corresponds to the max degrees per second. There is an evaluation board available at Future and Arrow that includes all the caps in the sample application in the datasheets. The part number has an -EB appended to it. Those devices are about the size of a pencil eraser and are a ball-grid array so you can't solder them by hand. The EB parts look like a basic stamp and can be pushed into a regular 20 pin IC socket.

They are not exactly cheap. The ADXRS150EB (the one in a DIP package rather than the ball grid array, which is hard/impossible to deal with for most people) is $94 from
Future Electronics. I have a recollection of a price of $75 or so from NewarkInOne.com, but when I went there to find it, I struck out.
As to compatible with the Stamp2, you are more or less on your own. I feel pretty sure that you will struggle to do the calculations you are likely to have to do without a faster CPU, but don't let me stop you.
Good luck.

P.S. You could always ask around on Chief Delphi for old FIRST gyros. Many teams never touch them. You may be able to find a bargain. JJ
