Creating marble machines that produce music when the balls hit objects, Martin Molin of the band Wintergatan (which I’m pretty sure is just him and his machine) knows precision ball-dropping is of utmost importance. So he developed this ball gate that can release his musical marbles with a standard timing deviation of just 1.46 milliseconds. That’s 1.46 thousandths of a second, or, in layman’s time, pretty damn accurate.

In the video, Martin demonstrates what 1.46 milliseconds sounds like to the naked ear, then delayed 10, 20, and 50ms until you can actually detect a noticeable difference. So yeah, it’s safe to say the machine drops those balls when it’s supposed to. Below is a video of the sort of insane machine Martin needs, such a precision marble-dropping gate to power.

Hey, everybody needs a hobby. And if your hobby happens to make beautiful music, all the better. But if your hobby happens to make a bunch of deafening noise in the garage and start the occasional fire, well, welcome to my life. My wife says I should take up reading or painting instead of trying to build a rocket.
