PaperTTY

I like an earlier thread about PaperTTY: https://news.ycombinator.com/item?id=17896825 . The github project at https://github.com/joukos/PaperTTY links to youtube videos showing console use with an eink display.

If you're online interested in limited quantities, this Sharp display might well fit the bill: https://www.adafruit.com/product/4694 It's a "memory LCD", which has very low no power drain when idle, but has an LCD's refresh speed (i.e., fast enough to display video). You can also get some decently-documented eInk boards from Waveshare in 1" to 13" sizes, though the costs are definitely too high for anything but one-off Maker projects: https://www.waveshare.com/product/displays/e-paper.htm You may also find the PaperTTY project interesting for your TUI: https://github.com/joukos/PaperTTY

There is lots of interesting code here https://github.com/joukos/PaperTTY

I have been trying to build an Rpi+eink screen laptop, using https://github.com/joukos/PaperTTY But haven't touched the project in months now.

You forgot the best resource https://github.com/joukos/PaperTTY discussed at https://news.ycombinator.com/item?id=17896825 You can buy fairly cheap displays from https://www.waveshare.com/ along with Raspberry Pi HATs and the PaperTTY project gives the power to do a partial refresh instead of full screen refresh on these screens. The waveforms are available in the Waveshare open source code and you can modify them as you will. I am getting my screen next week and hoping to make my own little emacs only laptop using a Rpi Zero.
