Why Amazon can't use its economies of scale to build a Kindle monitor that devs and writers would early adopt like wildfire is a strange curiosity.

#72It seems to update fast, but with significant ghosting, right? Looking at the cat example. Maybe this is just the best e-ink can do, and thats fine!
Thanks! Yes, it does update quickly, and ghosting is still an issue, though I think there’s room for improvement on the OS/software side. I gave a talk at the Linux App Summit earlier this year where I shared some ideas for how this could work. https://www.youtube.com/watch?v=C7xTs9-2AgU
I think, if you look at Boox and how they have display options and config for each app, you could do this for X11 quite easily. Especially a custom backend video driver which flattens to greyscale, and distinguishes change on a per app basis.
An incredibly hacky thing, is that (as an example) Sawfish is an immensely extensible window manager. You can literally drop in lisp code linking actions by tagging on window names, application names, and so on.
So you could actually extend sawfish quite easily, and then do what Boox is doing. Change per-window methods of refresh, by interfacing with the backend video driver in X11, and so on.
I think a lot of people who don't use Linux, would "put up" with Linux if there was a way to use a framework with a display. So I think, strongly think, that the display of course and your work of course must be done, but that it relies very strongly on slapping together a more holistic environment.
Just thoughts. And good luck with this.

Thank you for your thoughts and support. I agree, doing this in X11 is definitely doable. I’ve seen others achieve similar results by running a daemon that listens for damage regions. I hadn’t considered using a custom backend video driver; that’s something I’ll be looking into.
My focus has mostly been on Wayland, but possibly prototyping in X11 could be a starting point. Some people I've met are interested in using computer vision techniques at the hardware level, or making a camera rig.
What excites me most is getting this into people’s hands, seeing what they create with it, and working together to improve it and explore new use cases. One use case that I learned about recently:

Heh, neat use re: tank + fish!

#75Looks like they would be good for Home Assistant dashboards.
That was my very first thought as well. I'm wanting to build a display that can show the status of various things - garage door, temperature, air quality, etc. Ideally it could run on battery too so I could mount it anywhere. Just need to find the time and motivation to do it, among all the other priorities & interests.

There's a lot better being done by Boox, and even with colour e-ink in terms of ghosting. I think a lot of that is software end, though. The one unfortunate thing is that this monitor seems to have a glossy screen, not matte, but maybe that's an additional layer over a dev kit? If this truly is 'open', then it should be trivial to write special X11/Wayland drivers for it, to handle a lot of the ghosting issues at tha…
The screens included in these kits are glossy, however the board can support pretty much any screen up to 13”, including matte and flexible. On the ghosting - we’ve been thinking a lot about Wayland drivers and other software solutions. We’re working on an SDK that allows a compositor or other software to not just refresh portions of the screen but also change the display mode for certain portions as well.

It’s obviously the left one. I don’t see much glare on it.
You don't see the glare on the left hand side? Are you trolling me? https://imgur.com/AsMMNmi https://imgur.com/a/kHBiPmu

Thanks for sharing! Would it be alright if I try it out during our livestream this week?
Hi Alex. If you are interested in showing VSCode, here are the theme and additional color settings that I use with my Mira Pro:

Possibly not the best syntax highlighting, but generally makes the UI legible.
Feel free to use.

I talked to my wife constantly about how badly I want an e-ink monitor, they’re just still so expensive for the specs I want haha. I’d take a solid 24”, maybe 21”, b&w 30hz at this point if the price was right (sub-$500).
Yeah, to get a 24" e-ink monitor anywhere near that price, we’d need much higher production volumes. Right now, it just isn’t mass-produced enough to bring costs down to the sub-$500 range.
Since you are really into that stuff, could you please share your opinion about the widely shared view that e-ink remains artificially expensive due to patents ?
Or point to reading material you find truthful. Thanks !

Even without the advantages of e-ink, a display which one can view _anywhere_ is a compelling thing, which opens up a lot of possibilities --- my favourite Windows device was a Fujitsu Stylistic ST-4110 w/ a transflective LCD, which I used as my main computer, e-book reader, notepad (writing/drawing/annotating with a stylus), and map display when traveling. The transflective display eliminated issues regarding reflec…
