Build a bike generator to stay connected during your city’s next power outage
As we become more and more reliant on electricity, power outages hit us harder and harder. The solution is simple: build a bicycle generator.


A magnet DC motor is spun 50 times for each revolution of the bike wheel, a home-built charge controller monitors the batteries for when to kill the charge, and a power inverter lets you take advantage of the accumulated juice. How do you prepare for when technology fails you? Use technology to prepare for the worst.
