Thanks for sharing, maybe it's time to buy some more old Kindles... I use bunch as smart paintings (with changing pictures generated locally with stable diffusion), and of course Home Assistant dashboard. They are awesome little machines.
Look at CrowPanel, you can get nice e-ink devices made for development, at a reasonable price. I have a small 2.13in esp32 board, I spent some time yesterday making it into a pocket flashcard device for my German courses. The energy consumption is minimal, small form factor, easy to flash via esptool or arduino utils
