How many times while you were using your bike your phone battery was flat, and you couldn’t snap some good photo or you couldn’t make a phone call?

Not anymore :) The guys at MAKE created an easy to do video.

  • How does it work?

With help of an alternator, a very simple and reliable generator that converts the rotational momentum into AC electricity.
The charge circuit consists of a rectifier, a capacitor and a voltage regulator.
The rectifier contains four one-way electrical gates called diodes which, working together, convert the back-and-forth wiggling of the charges in AC to a series of DC charge pulses.

The large capacitor connected between the DC terminals of the rectifier smooths out these pulses, charging up when there’s more energy in the system and discharging when there’s less.

Finally, the voltage regulator holds the incoming DC power down at a steady 5V, which is what most cell phones and other mobile devices are designed to accept.

REMEMBER !!!

Without the regulator in place, the charger might deliver more than 5V to your device, which could damage it.
