FREE pedal powered Bicycle charger that costs around $10! More videos at: http://www.kipkay.com Subscribe to Kipkay: http://bit.ly/SubscribetoKipkay Facebook: https://www.facebook.com/KipkayVideos Thanks to Alastair Bland for the idea. Here's how it works: The cable from the generator leads first to the circuit board's bridge rectifier, which converts the AC to DC. The up-and-down, positive-to-negative current becomes a steady positive current. Then, the cap levels out the DC voltage, producing a steady voltage inflow to the voltage regulator, as the phone only needs 5 volts to charge. Fast pedaling can produce 30V or more, which is enough to fry a cell phone. The regulator puts a five-volt ceiling on the power entering the phone. ►More LED Videos: http://bit.ly/LEDProjects ►Laser Videos: http://bit.ly/KipkayLaserVideos ►Easy Projects: http://bit.ly/KipkayEasyProjects ►Pranks & Jokes: http://bit.ly/KipkayPranks ►Hacks & Mods: http://bit.ly/KipkayHacks ►Spy Gadgets & Devices: http://bit.ly/KipkaySpy ►Explosions & Loud Things: http://bit.ly/KipkayExplosions
