Can two ordinary US pennies power an LED oscillator? In this fascinating electronics experiment, I compare a pre-1983 copper penny with a modern zinc-core penny to create a simple coin battery and run an efficient Joule Thief circuit. Watch as two coins of the same value produce enough voltage to flash an LED and reveal the surprising science hidden inside everyday pocket change.
If you enjoy electronics projects, science experiments, alternative energy demonstrations, LED circuits, coin collecting, and unusual DIY builds, this one is for you!
