Root Beer Bottle on a Tesla Coil

A demonstration of what happens when you put a root beer bottle on a Tesla coil. The metalllic flakes embedded in the sticker cause a very interesting reaction.


Star Wars, The March of the Empire Played on a Modulated Tesla Coil

With the "tesla coil" or "tesla transformer" it is possible to generate high voltage, high frequency alternating currents with relatively little effort.

What is special about the displayed coil is its fully electronic excitation system which makes it possible to ignite and extinguish the electric arc at any desired rate. The expansion and contraction of the air at each ignition, which creates the thunder in nature can be controlled.

The air starts to vibrate which is then perceived as sound or note. It is possible to superimpose up to four notes at a time to play chords.

The generator can import and convert MIDI files which enables it to play any music with up to four simultaneous notes.

Doctor Who Theme Song Played on Tesla Coils

ArcAttack employs a unique DJ set up of their own creation to generate an 'electrifying' audio visual performance.

The HVDJ pumps music through a PA system while two specially designed DRSSTC's (Dual-Resonant Solid State Tesla Coils) act as separate synchronized instruments.

These high tech machines produce an electrical arc similar to a continuous lightning bolt and put out a crisply distorted square wave sound reminiscent of the early days of synthesizers.


Tesla Coil + Argon + Paper Towel + Sword = Fire and Lightning

Bill Beaty (wbeaty) brought some Argon (among many other things) down to Hackerbot Labs to play with the Tesla Coils.

We filled a glass Florence flask full of argon and capped it with paper towel. Set said flask on top of a Tesla Coil. We also had a grounded sword-thing (named "Daggar"). Sparks from Daggar ignited the paper towel.


Singing Tesla Coil Video

This is a solid-state Tesla coil.

The primary runs at its resonant frequency in the 41 KHz range, and is modulated from the control unit in order to generate the tones you hear.
