4M Green Science - Windmill Generator

This kit is recommended for ages 8 and up, with potential need for adult supervision during assembly due to small parts.

You will need a small crosshead screwdriver and a clean soda bottle.

The amount of electricity generated is just enough to power the small LED included in the kit. It is not intended for powering other devices.

It works best outdoors or in a location with consistent natural wind. You could use a fan indoors to simulate wind, but it requires a strong enough airflow.

The diameter of the assembled rotor is 14cm.

No, batteries are not required. The LED is powered directly by the energy generated from the wind.

Assembly time can vary, but typically takes around 30-60 minutes depending on the builder's experience and age, especially with adult assistance.

Ensure the LED wires are securely connected to the motor terminals. Check that the rotor is spinning freely and is catching enough wind. Verify assembly steps were followed correctly, especially regarding the motor and rotor connection.

Make sure there are no obstructions preventing the rotor from turning. Check that the rotor shaft is properly seated in the housing and gear. Ensure the assembly is not too tight, which could impede smooth rotation.
