Here's some hopefully constructive feedback.

The RGB LED looks jarring against monochrome e-ink screen. It also gives impression of cheap electronics, and rough 3d printed case doesn't help. The e-ink feels elegant, solid (no flickering) and timeless, while LED is nervous, overly bright and loud. If you really need a LED, put a white one.

Maybe try to prototype audiophile hi-fi style case. Something wooden or even black glass. It would raise the price but there is obviously large interest.

The site doesn't give any information on programming, only that UART-USB is included. Is it serving web page? Can it execute user binaries? Is some GUI toolkit supported? Without providing this info you can hardly claim it's hackable.

If you checkout their hackaday and github page it seems to be programmable with arduino. [EDIT] links: https://github.com/rgujju/paperdink https://hackaday.io/project/168668-paperdink

I've wanted an e-ink display for a while, to display persistent-ish information for a while, like the Premier League table, local weather forecasts, and upcoming events from my Google Calendar, all in one screen. Unfortunately, they tend to be quite pricey and small, and I can't find pricing on this anywhere.

I bought a Nook e-reader off ebay a while back for something like this. You can root it and it's just Android 2.2 underneath. Not a fantastic dev platform, but my plan was to just have it display images, and all the real work is done on a server somewhere.

This looks a lot like it's just a waveshare e-ink display in a case with a esp32. Is there something more there?

If that's the case, ALL the work here is going to be software, and I don't see any yet. IIRC, that calendar display is example code from somewhere (the weather icons, in particular).

Hi, this looks interesting. What are the specs? Physical size and pixel resolution width * height? Number of levels of grey?

I spotted a couple of typos in the initial message in the setup screen: "Lets setup" should be "Let's set up". ("let's" = "let us", but "lets" = "allows", and "setup" is the noun but "set up" is the verb form.)

Last time I looked into this, for a potential project, I found Waveshare seem to be the leaders for the hacker/hobby space. They’ve got a nice 12.5” display (1304x984) @ $170, which is pricey but big enough for league tables. https://www.waveshare.com/product/displays/12.48inch-e-paper...

That one has red as well as black. They have a bunch more, mostly standard monochrome (a bit cheaper, and probably faster to update): https://www.waveshare.com/product/displays/e-paper/epaper-1....

Have updated the specs. Thanks for pointing out, typos seem to be a careless mistake.

That was surely insightful. We'll test with a white LED.

And we're working on the binaries and GUI, it seems like current hardware won't be able to serve web pages.

Yup pretty much. But everything is open source. checkout their github page https://github.com/rgujju/paperdink
