Hackers love to build instruments out of things you don't expect to be instruments. Whether they're remixing the Windows theme to be a trance hit, or teaching Tesla coils to sing, nerds love making objects play music. But David Levi has them all beat.
Levi build a cello out of magnets. The "bow" is a magnetic rod, the strings are ribbons connected to an oscillator, and the bridge is another magnet. Nor is this a sampling device either: Levi didn't record a cello and program a computer to play back anything prerecorded. Here, listen to his rendition of "Twinkle Twinkle Little Star":
Yep, that really is the unaltered sound of the magnetic cello. He actually made it sound like the real thing.
Here's our question: is it any easier to play than an actual cello? And for his next video, can he play the theme to Jaws?
