I got bored today and decided to start making my own battery using lemon and Coke. Here is the result, a 5.16V battery:
**broken link removed**
There are a total of 11 cells - 10 slices of lemon and a bowl of Coke. Each cell provides around 0.47V. The 2 electrodes are the aluminum strip from the Coke can, and Singapore $1 coin.
Although it provides a 5V, the current is only enough to light up an LED briefly. The LED can light up brightly with a single 1.5V AAA cell.
Just for fun Suggestions to improve the voltage or to make the LED brighter are welcome.
