Buffered Multiple Design Critique
There's a lot of great critique here, so I just wanted to offer another resource for you: the schematics to our precision buffered mult (for CV and audio) are open source: https://github.com/wntrblm/Hydrogen/blob/main/hardware/board/board.pdf

How would you controller 100+ stepper motors (each with their own home sensor) on a single Raspberry Pi?
You might want to check out Scottbez's open source split flap display project (https://github.com/scottbez1/splitflap). I've also been interested in replicating/streamlining this someday since I don't like the idea of manually applying vinyl lettering to all the PVC cards.

Source for flip or rotary digit displays for a project?
https://github.com/scottbez1/splitflap Found this long time ago, but is too complex for me

Binging show with 7yo during his spring break. Which lead to our latest purchase.
For what it's worth, I've been keeping an I on https://github.com/scottbez1/splitflap for some displays. At some point they have a easy version.

Vestaboard – A Smart Display to Connect and Inspire
I was looking at these the other day - in the process of browsing around the subject I found this maker-project to create custom ones:

Open source “split-flap” mechanical display
Scott Bezek has a great video on "How a Split Flap Display Works" [0].
He also sells blank "flaps" on Tindie [1].
The documentation on how to build the Split Flap is also really awesome [2], including how to cut your own flaps [3].
I've been following this project for a while. It's pretty awesome. I estimate about $10 per character (as opposed to the $180/character (!!) another poster mentioned through Alibaba), with a large portion of the cost being the custom cut "flaps" (in small quantities). It seems like the cost could get in the $2-$4 range per character but I couldn't figure out how to do it without a significant amount of labor involved in cutting the flaps.
FYI, there's also a company called Oat Foundry that sells large split-flap displays [4]. I seem to remember the cost being in the $10k+ region but I don't see a price and I could be way off base.
Oh, interesting, I see Vestaboard also has a (smaller) one for around $3k [5].
