Making an Infinite LEGO Domino Ring

A never ending (theoretically) domino ring, built using LEGO bricks. Turn on captions for some commentary on the build.
Building instructions: jkbrickworks.com/infinite-dom...
1 hour live stream test: kzbin.infoUtSvkF64d6w
The ring contains 64 dominos. A ramp runs along the inside of the ring, opposite the falling dominos, to lift them back up. A Mindstorms EV3 is used to monitor and control the speed of the ramp so that it matches the falling dominos.

Gotta love the engineering behind using the sensor to speed up or slow down when necessary, essentially eliminating randomness. And the smart move to close it by going really fast, so the dominos end up upward.

[@JKBrickworks]

I got annoyed pretty quickly raising them back up manually after every test, which is why I finally programmed in the fast finish. So happy I finally did that. :)

Such an elegant solution to the problem. Having the pieces on hinges is a good compromise but I just can't help but think it's not the same as having them without hinges.
