MIT scholar builds a self-balancing unicycle to roll fast and furious around campus (video)


Sure, we've shown you the goofy SBU v2.0 unicycle, but what's better than a glorious DIY project? MIT student Stephan Boyer has built his own electrical uni-ride, which he's dubbing the "Bullet." The single-wheel transporter packs a custom MIG-welded steel body, two 7Ah 12-volt batteries, an ATmega328 chip and a 450-watt electric motor. While the Bullet isn't the speediest of solowheel demons (15mph max), it's on par with its $25,000 Ryno Motors counterpart. As far as power efficiency, the Bullet can go up to five miles on a single charge -- more than enough juice to hit a few classroom round-trips. There's some "Learning to Ride" tips from the creator himself at the source link, but in the meantime you can watch this unified purple rider in action after the break.
