Summary

The Kidwind Firefly kit is a low cost, easy to use introduction to all aspects of understanding wind turbines. The kit comes with some blade cut-outs wich any grade level can use with the Firefly to understand how the wind can make electricity.
To take it a step further replace the LED with 2 wires and make some bigger blades to explore the areodynamics of making electricity from the wind.
Check out my Youtube channels for Firefly activities.
Here are a few simple 3D printed parts that adapt the Firefly generator to home made 3 to 6 blades. 150 mm to 180 mm blade lengths work well with a standard box fan.
Have Fun!
Note: Redrill the holes to fit the generator.
