Solar Fan Mini xUmp STEM Kit - Build Your own Solar Cell or Battery Powered Fan

Product Description

This kit is an economical introduction to solar cells / photovoltaics (PV), DC motors and how fans work. Included are: solar cell, high-efficiency DC motor, two fan propellers, AA battery holder (for indoor activities) and on/off push-button switch.

The solar cell, DC motor and battery holder all come with already attached wire leads for easy connection (no soldering required!).

Simply connect the 2 wires of the motor to the 2 wires of the solar cell (just strip and twist them together), expose the solar cell to sunlight, and like magic the motor comes to life. For those cloudy days, instead of using the solar cell you can connect the included single AA battery holder to power the motor (great for indoor classroom activities!) Add the included on/off switch to your circuit!

Fan propellers are interchangable and are easy to attach to the motor by just pushing them onto the motor shaft. One of the included propellers has soft, touch-safe blades which is great for younger children.
