Tesla coils

Tesla coils are electrical devices designed to generate high voltage, high frequency alternating current, which often manifests in the form of lightning-like discharges. These devices are quite dangerous due to the high voltages and currents involved. If you decide to build or operate your own, you do so at your own risk.
