In this project, I have built a Hand Crank Powered LED Torch using a simple DC motor, supercapacitors, a buck converter, and high-efficiency LEDs.
When you rotate the motor shaft by hand, it generates electricity to charge the supercapacitor bank, which then powers the LEDs for emergency lighting.
This torch is eco-friendly, fast-charging, and doesn't require any batteries!
Perfect for survival kits, outdoor camping, and educational science projects.
Materials Used:
- DC Motor (Generator)
- 3 × 2.7V 1F Supercapacitors
- booster Module
- 3V 50mA LEDs
- 100uf capaciter
- Hand Crank Handle
- Wires, Switch, Enclosure
Features:
- No batteries required
- Instant charging
- Safe and durable
- Easy DIY project
