We’ve featured a lot of awesome music made using floppy drives before, but this is the first time we’ve seen it used as the main instrument in a movie score, and by Emmy winning composer [Bear McCreary]. The movie, in this case is alien invasion film, Revolt, but you’ve surely heard Bear’s amazing work in the reimagined Battlestar Galactica series, The Walking Dead, Terminator: The Sarah Connor Chronicles (my favorite of his), or the one for which he won an Emmy, Da Vinci’s Demons wherein the main theme sounds the same backwards as forwards, to name just a few. So when someone of [Bear]’s abilities makes use of floppy drives, we listen.
[Bear] works with a team, and what they learned was that it’s a clicking sound which the drives make that we hear. It’s just so fast that it doesn’t come across as clicks. The speed at which the clicks are made determines the pitch. And so to control the sound, they control the floppy drives’ speed. They also found that older floppy drives had more of the type of sound they were looking for than newer ones, as if floppy drives weren’t getting hard to find as is. In the end, their floppy orchestra came out to around twelve drives. And the result is awesome, so be sure to check it out in the video below.

If you were an early 1990s youth, the chances are [Nirvana]’s Smells Like Teen Spirit is one of those pieces of music that transports you straight back to those times. As your writer it evokes a student radio studio and the shelves of its record library, and deafening badly-lit discos with poorly adjusted PA systems and unpleasantly sticky dance floors.
One of our finds this morning therefore comes as an evocative diversion, Smells Like Teen Spirit on [SileNT]’s Floppotron. The Floppotron is a music player composed of a huge array of floppy drives, hard drives, and a couple of flatbed scanners. The scanners are controlled by off-the-shelf Arduino boards and the hard drives have ATMega16s with H-bridge drivers.
This build is the most refined floppy drive organ we’ve seen yet. The floppies are divided into single-voice blocks of eight controlled by an ATMega16, with dynamic volume envelopes mad possible by the number of simultaneously running drives, so the sounds can fade in and out like “natural” musical instruments. The hard drives and scanners are run against their mechanical stops, providing percussion. All the boards are daisychained via SPI to an Arduino that acts as a PC interface, and the PC schedules the performance with a Python script.
He’s provided a couple of pieces as YouTube videos, the floppy motors work particularly well for [Nirvana]’s grunge, but perhaps a bit more mechanical for Hawaii Five-O. This last track will be more evocative than the first if you attended a particular university in the North of England where it was the end-of night record played as the lights came up in one of the discos that had a much better-adjusted PA because the technician knew what she was doing. For those of you with different childhoods, there’s also the Imperial March.
