If you're interesting in building your own you can get a 12" one from waveshare: https://www.waveshare.com/product/displays/e-paper/12.48inch...

This is the black/white one, they do a black/white/red one too. But beware, they take really long to refresh (the red color takes several refreshes to appear). And the one with red is on backorder till June.

It can be powered by a raspberry pi (or ESP32 or Arduino) and is (much) cheaper than the ereader options of the same size: Only about $170.

PS Beware: You can't simply start up a user interface like X-Windows on it. You have to write software to display on it. The display is addressed in 4 separate sections so it's not super easy.

I did some experiment with the bare version of this display, both with the b/w and the b/w/r displays. The black and white one can be partially updated (window mode) and is a bit faster. The four sections mentioned above don't have exactly the same size: two sections have slightly fewer pixels in width. I used a STM32 controller which came with the display; it had just enough memory to fit a whole image. It was interesting to write some 'generative' code for it...

Neat. I was looking for one of these. Wanted to make a KindleBerry Pi to do some writing/coding in a destruction free environment.

I wanted this for some time, an eink coding experience for outdoor use and good battery life. Do you know of any active projects online where people have got this working?
