I would love two wall mounted e-ink displays showing chess boards so my 14 year old son could play chess with his grandfather. I imagine the game keeping track of whose turn it is and being able to give voice commands to make moves. Then they could play games over a longer period of time, maybe make one move per day.

what's your budget :) the Lilygo T5 with Touch screen + a lipo battery would have all the hardware you need just need to port chess to the platform after that https://www.hackster.io/Sergey_Urusov/arduino-mega-chess-d54... figuring out NAT traversal to get them talking to each other from each other's homes might be tricky/fun, but there may be ways around that...

Pretty cool at $36.36 USD

It would be great to be able to buy this in a size that would mount easily into common photo frame formats.

Ideally with a battery that could last months and optional power.

If I was retired it's the sort of project I'd happily waste time on.

You have plenty of space behind the screen. Wondering if you could harness wifi signal to generate power. Given days between changes, perhaps you could harvest enough amperage to make a change.

Or maybe you could hide a Qi charger into the wall?

I have a similar display, and also use blue noise dithering. Mine is driven in the backend by a web browser, which means I was able to abuse CSS and mix-blend-mode to do the dithering for me: ha-card::after { content: ""; background-image: url(/local/visionect-dither.png); background-repeat: repeat; position: absolute; height: 100%; width: 100%; display: block; mix-blend-mode: multiply; } The dithering texture used i…

what are the 3d and 4d textures?

They’ll just keep repeating thus trope whenever an e-ink project comes up. (They don’t think that LCD screens have patents too?)

Surely most LCD patents have expired by now?

'And there are new ones as tech improves

Samsung sells an LED TV specifically for this use case. Currently only at 4K. https://www.samsung.com/us/tvs/the-frame/highlights/

I’m browsing this link for a good 5min. Looks interesting. I get that it tries to simulate paper, but I have no idea how. Even the “explore technology” link has little extra detail. I don’t even know if it’s backlit.

It’s just a tv with a picture frame and some additional software/wallpapers

Got excited, but then you qualified it was AI. AI art is not generative art, it is reductive "art". It requires samples of the art style you wish to cop, and it always produces something artificial and less than the sum of its parts. On the other hand, generative art is procedural, and represents the thought process of a human being. Better luck making meaning.

I despise how some companies opted to scrape artists works without their permission.

But aren't the prompts used also representative of a thought process? The chosen network architecture and the choices of images used to train also represent thought.

I think it would be interesting to hear from an insider (with examples/evidence etc) what the mechanism is for eink to be more expensive. I/e/ the fundamentals for why this is the case beyond economies of scale. Given this history of the patent it looks to the outsider like this probably isn't the case and short sighted rent seeking is the problem. Would love to be wrong though, so if you do have a good explanation t…

I’m sure the ad-driven subsidy on TVs plays a huge part. TV prices have declined as “dumb” TVs have been phased out of the market. A more niche tool like a large e-ink display might not make as much sense from to price this way since ad systems need large networks of users to be relevant.
