I’d be remiss not to mention that we (Pimoroni) sit right at the hacker end of the E-ink scale with stuff like Badger2040W [1] and Inky Frame [2], both of which pair (small and less small) E-Ink panels with the RP2040 microcontroller so you can BYO software. The biggest roadblock to these being super compelling is update rate. The black/white screen on Badger can be driven pretty hard, but overdriving it (a friend built a continuous E-ink zoetrope [3]) has consequences. Inky Frame’s 7 colour display is awesome for dithered artwork (missing cyan and magenta notwithstanding) but very, very slow to refresh- ~30s after the panels were updated to incorporate an unskippable “clean” phase. Faster, cheaper and bigger all seem mutually exclusive right now, but I share the authors passion for the format. 1. https://shop.pimoroni.com/products/badger-2040-w?variant=40514062188627 https://shop.pimoroni.com/products/badger-2040-w?variant=405... 2. https://shop.pimoroni.com/products/inky-frame-7-3?variant=40541882056787 https://shop.pimoroni.com/products/inky-frame-7-3?variant=40... 3. https://www.tomshardware.com/news/raspberry-pi-digital-zoetrope https://www.tomshardware.com/news/raspberry-pi-digital-zoetr...
