Homemade self-balancing unicycle uses an Arduino to help keep upright

Around the whim of the gold coin switch, Nick Thatcher once made the decision between creating a homemade Segway, or perhaps a self balancing unicycle. Despite the fact that the forces of fate find the former, Thatcher’s thirst to construct wasn’t quenched — he built the main one-wheeled scooter anyway. The Raptor looks nearly the same as a Ryno unicycle constructed from spares — a series driven wheelbarrow wheel run by a 350w targeted motor, a set of batteries wired in series, some PVC and thermoplastic, an IMU gyro as well as an Arduino UNO — all hobbled together to create a one-wheeled electric mount. Thatcher states the scooter can push 10mph securely, but faster speeds often outpace the gyro’s corrective efforts. Still, the bike promises between 90-two hours of face-plant free fun, provided the driver reaches least a little balanced. The motorized unicycle is not available, but look on to Thatch Industries for any parts list, or scoot on beyond the break to determine the bike for action.
