The Remote Bike project, caught our eye today. Inspired by “cliff hangers” on the tv show “The Price Is Right”, [atduskgreg] has built his own version. In this version, the bike on the mountain makes progress, or slides back down the mountain based on the speed you pedal. If you maintain your target speed long enough, you make it to the top of the mountain and win. The RPMs are gathered from a stationary bike using a hall effect sensor, then piped to an Arduino that controls the bike via a stepper motor and string. That seems fun, and a decent alternative to biking through google maps or something. We have to wonder how long this would be amusing though. Then again, when you’re on a stationary bike you are usually just using a timer or a heart rate monitor anyway, so this is pretty cool.
