Singing Tesla Coil at Duckon 2007
The above Tesla coil was programed to spark within the range of human hearing, and it plays a song! So cool. (You might want to turn your speakers down and then adjust up, it’s loud and crackley)
A duet of Tesla coils sing the Mario Bros theme. It’s really neat! I like to listen to this one.
The above is a long, techno-geek-babble filled explanation of how this is done; I watched the whole thing, but I’d recommend watching the first couple of minutes, until your eyes begin to glaze over, then skipping ahead to the place where they pan over so you can see the keyboard. The bits about the fiber optic connection between the keyboard and the coil are really interesting.
If you visit This YouTube page, and click on “More Videos From This Channel” there on the right, you will see a wide selection of songs that the duet of Tesla coils sing. The Tetris theme, woo!
