Safety & Liability Disclaimer
Replicating alternative electromagnetism or mechanical resonance systems carries extreme physical hazards including lethal voltage shock, explosive gas ignition, mechanical shrapnel, and chemical toxicity. All contents, schematics, and guidelines on this page are provided strictly for educational and historical research.
Device-Specific Hazards:
Very safe — low voltage.

Overview
A minimalist blocking oscillator circuit that boosts voltage from a 'dead' battery (below 1V) to light an LED. The basic circuit uses just 5 components. Advanced variants include MOSFET-driven versions and multi-stage cascades. The basic Joule Thief is a legitimate, well-understood boost converter. Patrick Kelly recommends it as the very first project for newcomers.
⚖️ What Would Convince Us?
To validate the anomalies claimed for this device under mainstream scientific parameters, builders and inventors must document and present evidence satisfying the following criteria:
Accurate RMS power integration of high frequency pulses
Chemical battery capacity degradation curves showing total energy conservation
Continuous output power measurement matching standard inductor formula
Investigation & Credibility Metrics
Direct inventor writings, patents, or lab notebooks available.
Effect matches accepted physics (e.g. basic inductance, ion wind).
Replicated and validated by multiple independent builders.
Oscilloscopes and power analyzers used to record transient waveforms.
This device is purely open-source or historical; no active sales.
Community Status
Kelly recommends as first project. Teaches fundamental concepts (inductor collapse, voltage boost, oscillation) needed for every other device on this list.
