Power your LEDs with penny batteries
Posted By: Vikas Shekhawat | Feb 8 2006
Here is a wonderful idea to power your LED with pennies. Mathew, the brain behind the idea, first creates a battery from pennies that gives 0.5 volts using zinc as the positive electrode and salt water as an electrolyte. He boosts up it to 2 volts by combining eight similar penny batteries in an ice cube tray to light an LED. The penny batteries finally produce around 110 micro-amps of current in series. Cheap and simple!
