This is a basic instruct able that tells how to make electric power two ways.
The first way is to use a motor generator. (handheld generator). The way to make this is to take a motor and crank it. If you crank the motor it will generate a little power. This generator makes power but it hardly can ever work because the power fades immediately after cranking.
I made my crank from a wheel and pencil. I cranked while testing voltage. It was like a game. I wanted to get a lot of energy so I cranked really hard. At the end my high score was 0.80 millavolts.
Step 3: How to Make a Penny Battery
To make a penny battery is easy. All you have to do is soak pennies in vinegar. Then soak paper as electrolyte in salt water. Get a piece of foil and stack the materials in the order penny paper foil or foil paper penny.
After that use a voltammeter to test the battery I got 0.64. millavolts. Please follow and fav. (: :)
