Perpetually knocks down and resets a domino ring.
Dominoes are made to be set up and knocked down. So Jason Allemann of JK Brickworks made a LEGO machine that perpetually topples an infinite ring of dominoes. It’s a useless gadget, but I could stare at it all day, and I’m sure you could too.
Jason Allemann is a well-known LEGO builder with decades of amazing projects under his belt. He regularly posts new creations (plus kits and instructions) through JK Brickworks, including various Perpetual Machines. And Allemann has designed some official LEGO sets, like the popular LEGO Ideas Marble Maze.
Regardless, Allemann’s Infinite LEGO Domino Ring features a circle of 64 red dominoes, perpetually falling in sequence and standing upright. Each domino works on a hinge, so after it is knocked over by a neighboring domino, a little spinning train resets it.
A LEGO Mindstorms EV3 device (which you’d normally use on a robot) regulates the train’s speed, making sure it doesn’t reset any dominoes too soon. As a result, the robot can knock down about 1,500 dominoes every minute of operation. (Allemann plans to do a one-hour test run of this machine to see how much he can handle.)
In particular, this project was inspired by Grant Davis’ self-stacking LEGO domino machine. Unlike the crazy ring we’re looking at today, Davis’s machine operates in a straight line and uses magnets to reset each toppled domino.
Be sure to check out Jason Allemann’s video to see the perpetual domino machine in action (turn on subtitles for some construction comments). You can also visit the JK Brickworks website to see more cool builds.
