How do tesla coils make music

Funny enough, that was actually going to happen this year. This was going to be our best year ever, and it literally just got wiped off the map. But just when they thought interest online had peaked — they hit 17, Facebook fans — one of their proteges, year-old Fabricio H. Franzoli, went viral. Suddenly his YouTube page skyrocketed in popularity, to over , subscribers, each video nearing millions of views. According to DiPrima, the rising voltage lifts all coils. And now, DiPrima and Franzoli, the Dr.

Dre and Eminem of Tesla coil DJing, are planning a collab. November 15, Will Tesla Coils make their way to Best Buy shelves this year?

That singing highway was awesome see the Nov. Manipulation of Tesla coils to make noise has been done before, but this takes the cake. Pitch is just the number of times the air vibrates per second. Higher frequency, higher pitch. Tesla coils are a combination of circuits that output thousands to millions of volts. That high electric field arcs up and out of the coil, filling the air with sparks and making it possible to light up fluorescent lights wirelessly.

Certain types of Tesla coils, like the one used here, are putting out hundreds of sparks per second, with a rest between each spark. That's already a lot like a sound wave. So, if you repeat this process at say times a second, you will hear an audio tone at middle C. Music can be played by controlling the length and frequency of the pulses you send to the coil. With these coils getting the frequency and length information is relatively simple from a MIDI audio source via a suitably programmed microprocessor.

Their output is essentially silent You do get a hiss at lower frequencies due to variations in the spark output. To get music from these coils you vary the power going in to them in a very similar way to an AM radio transmitter. There is two ways of achieving this.
