Self-balancing one-wheeled skateboard

So you think your Segway is all that and more? Sculptor Chris Coleman has gone one-up on your expensive Segway with this homebrew solution of a self-balancing one-wheeled skateboard that is based on Ben Smither’s design. The entire metal frame was fabricated by Chris himeself, and he uses an Arduino microcontroller to help maintain the skateboard’s balance (along with whoever stands on it). Chris was also generous enough to publish his code, making it freely available to anyone who wants to construct one of these in their basement. Not too sure if you can grind with one of these though.
