I love e-ink and these look really cool, but yeah, that price. Where are you currently getting your displays? You may be interested in EPDiy [0] (controlling cheap left over Kindle DX screens with an ESP32) and Inkplate [1] for some inspiration on cheaper sourcing. For reference: the 6" Inkplate costs around 100€ and I think you could fairly comfortably build a 10" EPDiy device at around that. That's without all the fanciness of course, with it I reckon it should be possible to sell these things at around 200€ each, which would probably make them a lot more interesting to people. That said: I'm excited for color e-ink screens appearing on the market. The amount of devices released lets me hope at least some will make it to a secondary market.

I actually have an Inkplate at home. The 8 gray shades they support are unfortunately not evenly distributed, which makes it difficult to display images in good quality. EPDiy looks interesting, though.

  What does it do for shades that aren’t those 8? Does it apply any sort of dithering? Maybe it just needs a better lookup table or some preprocessing. I’ve seen some impressive 1-bit displays, so 8 shades shouldn’t be harder than that.

    You can't define more than 8. The API allows only 3 bit input. I also tinkered with the lookup table, and was able to create a lot of different gray shades, but I was not able to produce ~40-60% gray.
