Another great option is Pimoroni's combo eink display + pico w https://shop.pimoroni.com/products/inky-frame-7-3?variant=40...

Why aren't there any CMYK screens?

The frustrating twist is that - under the hood - this screen is CMYK. There’s a magenta “ink”, which would fill out a huge gap in the colour gamut, that we can’t even use. The same applies to cyan. Both colours are fundamental to the display tech and yet poorly represented in the very boring 7-colour palette.

That frame makes it look like ancient technology rather than 'picture frame'.

I know, right? What a hideous frame. It somehow makes the screen look worse! I smile fondly and lightly jab at hackers complete lack of concern for aesthetics.

Look at the competition though. Most don't come with a frame at all, or maybe a 3D printed frame at best. This is at least wood.

I think it’d be a little more honest if the first sentence started with „I offer a display with a simple API“. https://www.invisible-computers.com/imprint.html

No worries. I actually like the display. Looks neat.

I didn't even know there are decent e-ink colour displays available. I have to admit that I've been wanting to do something similar for a while, but I've always been too lazy to start, so kudos from me for that project! I love e-ink in general, it's a shame that it's still so rarely used. My fossil hybrid hr watch uses it, for example, but though the watch itself is incredible, the app is pure garbage. If that weren'…

Don't know whether you're on Android but Gadgetbridge[0] might be the answer to your Fossil app woes [0] https://codeberg.org/Freeyourgadget/Gadgetbridge/wiki/Fossil...

Thanks!

Puh, that's harsh. But you are right, the frame is too wide. I am trying to make it narrower.

I think it's nice. It's about the same form factor as the existing paper-holders it replaces and in this context the wood border is aesthetic and clutter-reducing.

My work went with LCDs which don't match the calm wood and earth colors decor of our meeting and privacy rooms.

Not that you asked, but what I'd tweak would be a way to run the cable back into the wall.

I think the world of homebrow eInk devices is set to take off. The problem right now is that while the screens have come down in price considerably, the driver hardware remains expensive and proprietary. If you want to build something for cheap, you'll be designing the PCB from scratch (as this author did). Enter EPDIY, which brings wide support to a variety of screens using commodity hardware. It's still under devel…

following this project for a while. Though I dabble in computers for quite a while now, going the whole order-your-own-pcb-and-then-solder-some-more route is quite jump for me. I think there's more people like me.

Would really hope some integrators can do this en masse and charge a normal fee for their trouble and provide me with a hackable EPDIY without the hassle.

"... With only 7 colors and a refresh time of about a minute ..." Ouch, even worse than expected. The project is interesting, but I'm totally unimpressed by these numbers; I wouldn't pay a premium for a sub par display that is slow as a dead sloth. A traditional LED screen plus some tricks to save power would make a much better picture frame IMO. I would for example use a PIR/microwave sensor (they're cheap!) to dete…

It seems the state of the art for color e-ink is at the level LCDs were in the eighties, perhaps nineties for b&w e-ink. You'd think the company holding the patents has little incentives to push the tech forward at a faster pace, given the slow advances seen in the last decade and a half.

Laws of physics don't change. Patents aren't the problem.
