I made something similar with the LilyGo T5 the other day:

You can probably adapt the code to drive this display, and it displays an image from a remote server, so all you need is an HTTP server and you can easily display whatever you want.

Or you can buy Soldered's: https://soldered.com/product/inkplate-6color-with-enclosure-...

How does this look in real life? 5.85-inch, 600x488 pixel electronic paper with the ability to display 7 different colors Does the dithering work well enough for a photo?

I have built one by myself with a waveshare display. The dithering is visible and the contrast is bad. But from distance it is not noticeble.

That title is nerd porn.

The entire site is nerd porn. If you haven't read the one where he installs Linux on a hard disk, here it is: https://spritesmods.com/?art=hddhack

On one of the hard disk controller chips that is..?

Don't see the advantage of eInk for a digital photo frame. Presumably these stay in one spot and can be left plugged in? Would think that a bright LED display would give much better picture quality.

Personally I prefer using e-ink panels for my home DIY projects because I'm sensitive to light polution - I don't want half my home to constantly be glowing at me from every direction. E-ink panels are not emissive, so they don't have this problem.

I'm even pretty annoyed at spurious LEDs. I appreciate for example that Sonos speakers let you turn off their status LEDs. It just makes the ambiance calmer.

The exception is very interactive stuff like https://hackaday.io/project/190477-hyelicht where I used an LCD for the embedded touchscreen in the shelf, but powered down unless you touch it.

Or this one, which has less of a hacker aesthetic. https://shop.invisible-computers.com/products/invisible-cale... It also comes with software out of the box

Looks like it's black and white?

Personaly, I don't like light emitting photo frames because I always get the feeling of "that's a display showing a photo, not a photo".

Wow! There's a dynamite product in here that pairs a daily nagging app and one of these displays so that people are reminded to take a new picture, ever day, and have it show up on someone's (or all subscribed) photo frame. I'm thinking, like, "take a photo of the kids so it will show up on Grandma's frame" kind of functionality. Though, obviously, it would also be used for porn, so there's a market there, too. Anywa…

We don't have anything to nag us, but the grandparents and aunts and uncles all have Nixplay[0] frames that we regularly update with photos of the kids.

I wonder if we’ll ever see significant improvements in e-ink contrast, which is still very poor. There hasn’t been much progress over the last decade. I’d love to have laser-printer-level e-ink.

I've done the same and I'd say that it didn't produce a great result. I did it for my father as a gift and while I liked the project because of the novelty of 7 color eInk tech, the image was low res, dithered, and tinted yellow. My father was grateful but he probably would've liked a normal LCD display lol
