I've hacked together a WiiMote and MotionPlus to provide a wearable MotionPlus on the wrist extended off the WiiMote, and I'm sending the data back using Bluetooth over HID. I use a program to decode the output, which is all working fine.
The problem is that the gyros in the MotionPlus (the ITG-3200) can only handle +/- 2000 deg/sec, which is far too easily maxed out when throwing a baseball. Recorded rates using our high speed lab and Direct Linear Transformation show readings up to 7000 deg/sec!
We're not in need of a full IMU as I only care about measuring roll (forearm supination/pronation), pitch (humeral internal/external rotation), and yaw (elbow extension/flexion) - so a three-axis gyroscope is perfect.
Any suggestions on where I can get one that supports up to 10,000 deg/sec with good resolution? I have very limited understanding of electronics but I'm certainly willing to learn; my math skills are reasonable and I've seen enough Processing code for Arduino that I think I can figure it out given enough time.
Thanks for all your help!
