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.

There's some info on my Hackaday project listing: https://hackaday.io/project/190478-hyepaper Also the album link in the other comment.

You could really gaslight house guests with this. Just deny it's changed.

Do you think people are fooled by any tech these days?

I suspect people expect everything to be magic now.

That's a very neat project. The only issue I have with it is that it's basically a passive energy waster. It produces images by burning GPU power, when it could instead curate art from an existing amount of art (of which there is more to ever go through, almost in any category). Some projects that use AI could be replaced with other tech and be much more efficient.

My home computer batch processing prompts thru Stable Diffusion can generate and then nicely upscale images at at rate of about 1 every 5 seconds. Or 360 per half-hour. Which means a newly image on the display every day to look at for a year in just an half hour of computation.

At about 300W of GPU + 120W of PC, that is 420W * 0.5hrs = 0.210kWhr. This is a rounding error on my monthly electric bill. About six cents.

I've spent more energy than that likely just sitting and reading HackerNews this week.

I have one of these, and only in a very specific environment is it convincing as not-a-TV (aside from the concerns of privacy and their proprietary app). Especially at night, I find the backlight makes it painfully obvious that it's just a TV and I'd much rather have something like e-ink which blends into the surroundings.

They look cool. Would be great to have an oled version without a backlight.

So far my guests are mostly puzzled by "Why'd you frame that?" until I tell them it will in fact change and isn't my most prized selection of news articles :-)

Which patents need to expire to have cheaper e-ink displays?

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?

Awesome project! I'd strongly recommend swapping in some antireflective glass. There's a couple affordable options with less than 1% reflection [1][2]. Made a huge difference vs. stock acrylic on my frames that get lots of environmental light.

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...

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.
