Musical Tesla Coils Dance of the Sugar Plum Fairy

Twin Solid State Musical Tesla coils playing Dance of the Sugar Plum Fairy at the 2007 Lightning on the Lawn Teslathon sponsored by DC Cox (Resonance Research Corp) in Baraboo WI. The music that you hear is coming from the sparks that these two identical high power solid state Tesla coils are generating. There are no speakers involved. The Tesla coils stand 7 feet tall and are each capable of putting out over 12 foot of spark. They are spaced about 18 feet apart. The coils are controlled over a fiber optic link by a single laptop computer. Each coil is assigned to a midi channel which it responds to by playing notes that are programed into the computer software. These coils were constructed by Steve Ward and Jeff Larson.

Save $3966/year on electricity bills - annoy your neighbours in the process

A man on Long Beach Island has erected a windmill in his backyard to cut down on electricity bills (saving him $3966 a year). But in the process he has really pissed off his neighbours who are saying the sound, equivenlent to a noisy refrigerator, is too noisy and the structure itself is too big.

Singing Tesla Coil at Duckon 2007


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.

So just to explain a little further, yes, it is the actual high voltage sparks that are making the noise. Every cycle of the music is a burst of sparks at 41 KHz, triggered by digital circuitry at the end of a "long" piece of fiber optics.

What's not immediately obvious in this video is how loud this is. Many people were covering their ears, dogs were barking. In the sections where the crowd is cheering and the coils is starting and stopping, you can hear the the crowd is drowned out by the coil when it's firing.

This Tesla coil was built and is owned by Steve Ward. Steve is a EE student at U of I Urbana-Champaign. He and Jeff have been going to Teslathons, which is where they met.

It's been suggested that a good name for this coil would be the "Zeusaphone". "Thoremin" has also been mentioned, though personally I think we need Theramin type inputs for that.
