The harpsichord and the clavichord are the historical starting point. Figuring out an alternative to the escapement was a multi-century journey.I tried to find a good video about how a grand piano action works, and there are many, but none really nailed it in my view: they walk through the parts but don’t do a good job of showing the motivations and the design pressures that shaped them. Everything there solves a problem!

@inthehands @paul_ipv6 Did you try youtube or tiktok (or something else?) I've found that fix it videos are MUCH better on tt because they impose time limits rather than using minutes watched as a signal of quality.
I don't know if that applies to explainers like you're looking for, but I watched 5 minutes of a YT video on Alcatraz doors and learned exactly nothing.

I used a general DDG video search. I’m sure something is out there somewhere. If you find it, lmk! -

We’d call someone, stretch the long cord waaaaay out there, and then do a kind of police sketch artist shtick while they drew it on paper -

Believe it or not, there were person-sized kiosks every block or so containing large books of telephone users in the local geographic area, with a unique seven-digit code for each user. (One of these books, printed on yellow paper, had a section for "photographers".)
Also in the booth was a coin-operated device, connected by wire to a central office, that allowed two-way voice communication with the person associated with each code number.

Ah…! The loss of the phone book as a metaphor, as a process example, and as a useful physical object is profound.Now for the phone book’s actual intended purpose…meh, our current situation is a net improvement. But for all that other stuff…!

Analog TV static is one I will certainly miss. There are so many emerging patterns in a random changing screen of dots-- with digital broadcasting, screens just go black.
