In this instructable, I'll show you how I created a simple yet working Pedaling Generator using a small Bike and a Motor Generator.
Of course don't expect to power you air conditioner or microwave oven with this simple pedaling generator. But it's cool and very educational for your kids. It really raises their awareness for energy generation and usage.
A small bike
A permanent magnet generator
Some plastic caps and old wheels to make the generator hub
Step 1: Motor Hub
Step 2: Found the Perfect Wheel
Here is and after I made this motor hub from the plastic caps I found this plastic wheel from a handbag.
I snapped it from its axis and installed it on the motor/generator.
Now I have a better motor hub.
Step 3: Mobile USB Charger
And then I got this USB mobile phone car charger and connected it to the generator terminals.
