I'm still catching up after a brief hiatus. Like Charles, I would want to build a self-balancer too, both to share in the wringout of Michael's work-to-date in a realistic application and to have something for my grandkids to tinker with. I had thought about self-balancers before. Earlier, I had been looking at a (now ten-month old) posting http://www.freetronics.com/blogs/news/7235638-make-your-own-self-balancing-robot#.Up0iDtJKW6Q based on an MPU6050 IMU (https://www.sparkfun.com/products/11028) but then my life crashed and burned. I won't pretend I've pored over the data sheets for these two units. At a glance, it seems the MPU6050 offers some nice onboard signal processing, but I expect either IMU will work (and both talk I2C) since from all appearances an inverted pendulum self-balancer is just not that hard to implement. I seen mention of 10ms loop times. As an aside, sparkfun has a guide to relevant products they stock: https://www.sparkfun.com/pages/accel_gyro_guide Unfortunately, the only IMU I have on hand is integrated in the controller assembly for my quadracopter -> too hard to break it out for experiments.
