A 3D Printed Marble Clock

There are clocks with pendulums, gears, and circuits. How about one with marbles? Initially designed in the ’70s, rolling ball clocks came in many designs and materials, but this is the future, so [gocivici] has created an Instructable to show you how you can 3D print and build your own.

Three rows of marbles keep track of the time, one for one hour intervals, one for five-minute intervals and a third for one minute intervals. It makes reading the time a bit more difficult than a pair of hands, but more fun. The clock uses the weight of the marbles …read more

Keeping Magnetized Marbles from Stopping the Music

Take a couple of thousand steel balls, add a large wooden gear with neodymium magnets embedded in it, and what do you get? Either the beginnings of a wonderful kinetic music machine, or a mess of balls all stuck together and clogging up the works.

The latter was the case for [Martin], and he needed to find a way to demagnetize steel balls in a continuous process if his “Marble Machine X” were to see the light of day. You may recall [Martin] as a member of the band Wintergatan and the inventor of the original Marble Machine, a remarkable …read more

How to Play the Bass With Marbles

Stringed instruments make noise from the vibrations of tuned strings, using acoustic or electronic means to amplify those vibrations to the point where they’re loud enough to hear. The strings are triggered in a variety of ways – piano strings are hit with hammers, guitar strings are plucked, while violin strings are bowed. Meanwhile, [Martin] from the band [Wintergatan] is using marbles to play a bass guitar.

[Martin] starts out with a basic setup. The bass guitar is placed on the workbench, while a piece of wood is taped to a tripod. The wood has a hole drilled through it, …read more
