Go green with your very own power generator!
Big industrial power generators make electricity by turning huge motors with coal and fossil fuels, but you can make your own with a small DC motor and some simple electrical components. I made this for fun one day because I needed a way to charge my flashlight batteries when I was away from home.
Step 1: Gather Your Parts
Step 2: Connect Your Components
So, the motor has two leads: one goes to battery(-) and the other goes to battery(+) through a diode. The LED goes to (-) and to the switch through the resistor. For a solar panel it's basically the same deal; just look at the pictures.
Step 3: More Current (Optional)
Connect in Parallel for more Current = faster charging
This step is pretty simple: just add another solar panel or motor and connect their (+) and (-) together using a diode, to achieve a faster charge. (look at the picture)
