Product Description

The Tesla coil is a transformer that operates on the principle of resonance. It was invented by Nicola Tesla who used these coils to carry out innovative experiments, such as electrical lighting, spectral fluorescence, X ray power source, high frequency alternating current phenomenon and radio energy transmission.

This is a DIY Tesla coil kit, which needs to be soldered and assembled by yourself. It is a very interesting small reproduction of a historical scientific experiment.  Using this kit it is possible to produce small amounts of high temperature and high-pressure plasma, ignite paper, transmit wireless signals, and light a fluorescent lamp wirelessly.

The most popular application of this kit is a plasma speaker, a new concept loudspeaker that uses an electric arc to vibrate the air. You can play mobile or computer music, the sound is not very loud.

 24 volt power supply not included.
