May 2011: This instructable is now quite old (relatively) and I could now rebuild this project more simply with an Arduino as the controller.
I am currently working on a unicycle with the same OSMC motor controller and an Arduino. When I get that to work I will also add the code to this instructable as the principles will be almost the same (one wheel one motor).
NOTE 2016: All my self balancing projects are now also documented on my Youtube channel here: Click
NOTE Jan 2013: I now have WORKING ARDUINO CODE that works well with an OSMC. The main points are outlined here:
JUNE 2014: I am entering the Hackaday Competition with Nick Thatcher and another friend. The entry is the Medicycle, yes it will have one wheel and yes it will be really cool. Best project yet hopefully. If you want to follow us, and we would very much like you to, here is the link:
