Here’s proof that you can build cool stuff with simple tools. This self-balancing unicycle uses an Arduino and a five degree of freedom IMU from Sparkfun to keep the rider upright. Well, it’ll keep you upright as long as you have good side-to-side balance. But that’s true of any unicycle, right? The Raptor was built by [Nick [...]

[Glenn] had an old electric scooter/motorcycle in his garage that had long ago given up the ghost. Without a working battery and motor controller this scooter wasn’t beyond repair, but [Glenn] thought he could use it to build something much, much cooler. What he came up with is a self-balancing unicycle that borrows inspiration from a [...]

The only problem with this self-balancing unicycle is it’s inability to balance itself. You see, it automatically balances along the axis that is parallel to the line of travel. But since there’s only one wheel the rider is responsible for balancing perpendicular to travel. This is really not too much different from a bicycle; balancing while in [...]

Focus Designs has a new version of their self-balancing unicycle for sale. This improves upon their original design in several ways. The battery pack has moved to LiFePO4, which is becoming more common in electric transportation. There’s also regenerative braking and fall protection which kills the motor when you fall off. We’ve embedded their marketing [...]

We had to call it an electric motorcycle in the title because electric unicycle just sounds lame. But the video after the break shows you that this prototype is anything but lame. It takes minimalism to the extreme when you’re talking about powered transportation. The self-balancer is reminiscent of a Segway but the rider sits [...]
