Hackers Make New Instrument Out of Hard Drives and E-Junk

It turns out old electronic junk can be pretty useful for making music. For one thing, you can program an array of floppy drives to play "Somebody That I Used to Know." And, as some Illinois hackers recently showed Wired, you can assemble hard drives and other assorted e-junk into mind-bending new instruments. 

Colten Jackson built the so-called Hard Rock Guitar out of six old hard drives, an obsolete keyboard number pad, an Arduino circuit board, and other items. And he ended up with a strange new contraption that sort of resembles a guitar — albeit one where you program the key it plays with the number pad, then spin the discs of the hard drive at various speeds to produce sound. Just watch:

So the hard drives spin and produce sound waves, which get transmitted via the Arduino board to software that then turns them into music. The number pad changes the notes in the scale. For a more detailed explanation (and sonic demo), check out the video above, and here's Wired's original post. But this just goes to show that old electronic junk might not be as junky as we think.

  • clipping at Brava Theater Sept. 11
    Sub Pop recording artists 'clipping.' brought their brand of noise-driven experimental hip hop to the closing night of 2016's San Francisco Electronic Music Fest this past Sunday. The packed Brava Theater hosted an initially seated crowd that ended the night jumping and dancing against the front of the stage. The trio performed a set focused on their recently released Sci-Fi Horror concept album, 'Splendor & Misery', then delved into their dancier and more aggressive back catalogue, and recent single 'Wriggle'. Opening performances included local experimental electronic duo 'Tujurikkuja' and computer music artist 'Madalyn Merkey.'"
