Energy harvesting circuit breakthrough using a simple AV plug, capacitor, and blocking oscillator to draw ambient power from household mains fields, WiFi signals, and low-frequency environments. In this experiment, I reveal surprising results using a minimalist AV plug harvester, compare multiple circuit builds, and demonstrate how a tiny pickup plate and even a standard mains cord can power an LED oscillator—even with the computer switched off.
If you’re interested in free energy experiments, ambient RF harvesting, AV plug circuits, blocking oscillators, Tesla-style wireless power ideas, or low-power electronics, this video shows real working results and unexpected discoveries.
