Hi everyone! In this exciting DIY project, we are building a high-speed Quad-Propeller Dynamo to harness the power of air and generate free electricity! This unique design features four high-RPM fans/propellers connected to motors, acting as a mini wind turbine to charge 18650 Li-ion batteries.
🚀The Project:
This project demonstrates how simple DC motors can be used as DIY generators to convert air velocity into usable electrical energy. We focused on a robust four-fan design for maximum rotation and efficiency. Perfect for science fairs, hobbyists, and anyone looking for a low-cost, off-grid power solution!
✅Components Used:
. 4 x Small DC Motors (used as generators)
. 4 x Plastic Propellers/Fans
. 18650 Li-ion Batteries
. Battery Holder / Charging Circuit (BMS)
. Wires, Switches, and Connectors
. Plywood or bScienceProject
✅Key Features:
. High-Speed, High-RPM performance.
Compact and portable Mini Wind Turbine.
Effective Battery Charging capability.
. Simple wiring and assembly.
