Video: Engineer turns swinging pendulum into a tiny battery that powers LEDs
SMRTR summary
Aerospace engineer Tom Stanton built a pendulum-powered battery system using magnets, copper coils, and 3D-printed components that generates up to 80 volts from swinging motion. The device converts a pendulum's kinetic energy into electrical power through electromagnetic induction, storing enough charge in capacitors to light LEDs for three minutes or run small electronics.
