Check out this cool marble music machine called the ‘Wintergatan Marble Machine’ – a hand-cranked music box loaded with instruments including a circuit of 2,000 cascading steel marbles. It took Martin Molin 14 months to make the machine. The marbles are moved internally through the machine using funnels, pulleys, and tubes. As the devices cycles it activates a vibraphone, bass, kick drum, cymbal and other instruments that play a score programmed into a 32 bar loop comprised of LEGO technic parts.
Martin Molin began work on the marble machine in August 2014 and hoped to spend about 2 months on the project.
14 months and 3,000 parts later it was finished. Marbleous
