Overview

A deep dive into high-voltage electronics and resonance, our Tesla coil steps a low DC input up to tens of kilovolts, producing crackling arcs and wirelessly powering nearby fluorescent tubes.

Highlights

  • Resonant high-voltage step-up circuit
  • Wireless lighting of fluorescent tubes
  • Hand-wound secondary coil
  • Built-in safety cut-off

The Challenge

Winding a clean secondary coil and tuning resonance safely demanded patience and strict safety practice.

The Outcome

Produces reliable arcs and has become a highlight demo for explaining resonance and induction.
