The most annoying thing about stationary exercise bikes is that they're incredibly boring. Spice it up by adding a monitor that moves through Google Street View as you pedal.
Stationary exercise equipment is awful: you pedal and pedal, staring at the same piece of wall, and then when you're done, you're still in the same place you started. If you'd like to keep your exercising a bit less boring, this pretty neat hack will move through Google Street View at the speed you pedal. The setup is pretty clever; containing only of sensors next to the pedals that detect a magnet that passes by every rotation. An Arduino then sends a keystroke to Google Street View to move the location forward. Check out the video for a demonstration, and hit the link for more details on how it was built.
