Musical Tesla Coils Answered

Two tesla coils are being used to play the mario theme song. This is the first time i have ever tried embedding something, so im hoping this works.

if there is no video there, here is the link:

many thanks to goodhart for telling me how to get the video in here.


Good grief. That is amazing. (rips up Christmas list, starts new, very one one)

must stop tazsing self LOL


Technically, it is very simple. Just hook up some speakers to whatever is playing it, and then tap into the line of one. Run it through an IC to change the voltage depending on pitch, and put it on some HV transistors. The transistors hook up to the line going into the tesla coil. There you have it. It's the same principal as sound activated plasma globes. I have done it to one of my small coils before.

I wonder, would it be possible to put speech through this system? I'm guessing it could be done--it's all just sound after all.

Could be interesting. I don't see why you couldn't talk through them... Might be hard to make out what you are saying though.

Maybe if you TALK ... LIKE ... THIS ...?

OMG--I need to build this and then throw a rave--could you imagine hours of tecno being run through these?

wow.....*drools on keyboard*.... how do you make it! someone post an instructable.

i'm starting my tesla coil project this winter vacation. i might post an instructabel, but im not sure how to play music on a tesla coil.

I saw musical tesla coils before and they were oscillating with big high voltage valve tubes and Amplitude Modulated (AM) by music.

heres another video. dance of the sugar plum fairy:

great balls of fire!!!!!!!!!

yep, no video. someone tell me how to put it in there, and i will edit it.

Looks like the entire line from YouTube was used.

it was, i figured that was how i did it, but looks like its not. i had no idea what i was doing and hoping that someone would tell me how to fix it.


So, the coils are driving the music and not the other way around, right ?

there are no speakers, the sound is the sparks at different frequencies. A computer is driving the tesla coils through a fiber optic cable (probably so it doesn't fry it)

Understood. So the frequencies being heard are literally driven by the bolts of electricity....wild.
