Watch A Computer Hardware Orchestra Cover Nirvana

64 floppy drives. Eight hard disks. Two scanners. Together, these has obsolete pieces of technology make up Paweł Zadrożniak’s incredible computer hardware orchestra dubbed “The Floppotron.”

In the video below, you can watch the Floppotron cover Nirvana’s hit song “Smells Like Teen Spirit.” As for how it works:

Every device with an electric motor is able to generate a sound. Scanners and floppy drives use stepper motors to move the head with sensors which scans the image or performs read/write operations on a magnetic disk. The sound generated by a motor depends on driving speed. The higher the frequency, the greater the pitch. Hard disks use a magnet and a coil to tilt the head. When voltage is supplied for long enough, the head speeds up and hits the bound making the “drum hit” sound. The disk head coil can also be used as a speaker to play tones or even music, but… that would be too easy and too obvious.

Aside from ’90s grunge, the musical machine can also play tunes like Darth Vader’s theme song and the intro to “Hawaii Five-O,” among many others.
