Exercise bike connects to original Mario Kart, Rainbow Road shortcut gets even trickier (video)

Canadian modder Brent Smith has managed to connect an aging exercise bike to Nintendo's perennial racer. Naturally, there's some Arduino involvement, but the whole setup plugs directly into an original SNES console -- no emulation necessary. Power-ups are accessed with a button in the center of the exercise bike's handles, each of which has a directional button for steering, while the pedals function as the acceleration button, accurate to one sixth of a rotation. According to Smith, "it's a lot harder than it looks" -- and we believe him. Watch his test-drive kart plow off-track in the video demo after the break.
