An incredible, marble-powered sound machine

Martin Molin’s contraption brought a ridiculous grin to my face:

NPR writes,

The “Marble Machine” is a musical instrument by way of a Rube Goldberg contraption, the love child of a barrel organ, a kick drum, a vibraphone and a bass — all powered by hand-cranked gears and 2,000 steel marbles. […]

The video, beautifully filmed and edited by Hannes Knutsson, gives you a real sense of the instrument’s size and engineering complexity in all of its carved wooden parts, which Molin built after drawing his design in 3-D software — the various elements are programmable, and Molin can change keys midsong. You can see videos about the process of creating the machine on Molin’s own website.

  1. His videos on how it works (part 1, part 2) are also fascinating.

    He planned on two months to build it. It took over a year before it worked well enough to film the video. They had to turn his shop into a film studio, because the machine had grown too large to move.
