I wonder now how hard it would be to make an 80x24 7 segment display. I’ve for a long time wanted to make an SSH terminal with e-ink so that the power consumption, and production cost is very low.
Probably want a 14-segment, rather than a 7, unless you’re okay with pure numeric display in your SSH. Also, I suspect the refresh rate would make that difficult to use – akin to an old 300baud setup without local echo.
And immediately solder the cable, wires or connector, I forgot and had to solder the Rose to Rosa, for it is not a fact that the ready indicator would survive the soldering with usual solder.
i.e.
Make sure to solder the cable to the PCB before doing the next step; I forgot and had to solder it with Rose’s metal because the temperatures needed for regular solder could have destroyed the display.
Big e-ink displays seem to be quite expensive for whatever reason. However there are those small e-ink price tags, that are pretty cheap. Some even have three colors - white, black and red. I was wondering what is used to change a picture on them. It should be something simple like SPI. Then it could be possible to do something fun with it.
Maybe doing a very coarse, but at least big display. Maybe a keyboard with changeable layout.
Iirc they are expensive because they make a big sheet with many defects, and then cut as many pieces as they can from it. Big pieces are therefore much rarer than little ones.

Cute, if a bit hard to follow.
Here’s a handy retranslation of one bit:
