The linked video is the introduction about Michelson and the machine, the implementation details, surely interesting for readers here, are staring with:
"(2/4) Synthesis: A machine that uses gears, springs and levers to add sines and cosines"
The links to the rest of the series are on Youtube but one has to fight the Youtube UI to see them. Also, at the time the videos were produced it was possible to click inside the video itself to go to the other videos, and I believe that feature was later removed from the Youtube. So I find it easier to find links here than on Youtube. Youtube prefers suggesting what it wants.
YouTube really does has the worst UI, and for those of us without a google account and aggressive blocking of tracking features, an even worse set of recommendations. Somehow the video you
linked to relates to some kid yelling about Fortnite, which is what YouTube decided was a good video to move on to, rather than the next video in the series. Oh well, at least viewing the playlist keeps things on topic.
