YouTuber Plays Toto's Africa on a High-Voltage Tesla Coil and It's a Pleasure to Listen To
Tesla coils are electrical resonant transformer circuits. They were first developed by Nikola Tesla in 1891 which is where their name comes from. They are used to produce high-voltage, low-current, high-frequency alternating-current electricity.
When the current hits them they make a pleasant little noise. YouTuber Franzoli Electronics decided to take advantage of that sound to play Toto's Africa and the end result is a really fun video that is a pleasure to listen to.
The coils, it turns out are literally playing the music due to the programmed phase, pulse width, and firing frequency. The music is achieved without the use of any speakers or audio/video special effects.
As an added bonus, the Tesla coils make some beautiful thunder-looking electricity beams every time they hit a sound. Franzoli Electronics says the coils look even better in reality and sound almost the same, just without the beat/percussion backing track.
Now, who wants to listen and bless the rains down in Africa?
