Checking the youtube channel, the operator of the machine has continued to refine his design, in the last video it barely shakes (https://youtu.be/ZddqSR1wXkE?t=3025), if it shakes at all. Weird fun dedication to a passion project ^^

He live streams all of his work too, which is absolutely amazing to watch four or five hours of him refining small parts of the complex machine he’s working on. I watched him make small adjustments to a tube the marbles drop into so they’d travel at just the right speed to the next point, but without binding. Slightly too loose messes everything up, and slightly too tight makes the marbles get stuck. He’s supported by Patreon fans, which is truly amazing that such a skilled and niche project can be put together from the funding of random people who believe in him.

He’s so openly collaborative too, it’s inspiring! There’s a vibrant discord community of makers, 3d designs, and engineers helping Martin solve problems and prepare a “Manufacturable CAD.”

Like, there are dozens of ideas linked in the video description for a contraption to divide one stream of marbles into four: https://youtu.be/U4B0i0VzXuA
