Brilliant idea!

Really interesting project. Maybe You'll find place for a Thermos/sandwich-holder, inside the frame, so You can store coffee and lunch in the Wheel. Am following this with interest. Regarding the weight, it appears a Little overkill to me, to use carbon-cloth, since the weight-addition will be negligible, related to glassfiber. And carbon, though very strong and rigid, is known to splinter, so.... But maybe You have other arguments for it. Happy Work with this project.

Trevor Blackwell developed an electic unicycle some years ago. And a Segway clone, version 1 and 2. Trevor Blackwell homepage You can download the complete software for the Unicycle. There's also pseudocode which is actually very simple, for the Segway clone. Maybe some inspiration there....
