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 saw this product a couple of days ago: https://sync-sign.com/eink-for-developers-turn-key-solution/... I am not affiliated with that company in any way.

This reminds me of that old SNL commercial for Newton post-it notes.

UPDATE 2:

We're live again.

Could not resolve issue with the current hosting service provider yet so made a temporary website and routing everything there, which took its time own again to connect to the domain.

Hopefully this isn't too late. It was really frustrating but many lessons learnt. Thanks everyone for all the reviews and feedback!

Have you shared this on /r/HomeAutomation and /r/HomeAssistant? Much less technical crowd in general than HN, but framing old tablets (as informational displays of 'smart home' state etc.) is quite popular, and I think your project is much more suited to it: much lower-power (such a device is only useful if always-on really), and much less distracting (e-paper not glaring bright colourful iPad or whatever). Looks gre…

Have posted on couple of others, will check these out

Earlier quoted context omitted.

Why do you need an LED at all?

Fully agree. A white LED might be better, as long as is for notifications only. There's no need for having a constant light otherwise (that's the beauty of eink)

we're tinkering around designs, will check without LED too

I really feel like the E-Ink invention has been mismanaged. These things should literally be everywhere by now and performing all kinds of functions. I want one as a second screen and to do most of my development on it. Maybe have a second one for pulling up documentation. Does anyone know why it has taken so long for these to go to market except, basically, for e-readers? Someone I know uses one of these as their ma…

>speaking in an inside voice as opposed to shouting at them

Now that's a way to put it! We were also perplexed while doing research initially as to why aren't these displays used more widely. One of the issues was cost and limited suppliers. So thought this might be a good thing to work on

This looks amazing I can think of some really cool applications like a nice PDF reader that formats technical docs correctly What’s the status on Color e-ink nowadays? Are we far away from that? I feel like that’s the holy grail, along with true multitouch on one (last I checked all e ink displays were resistive touch displays)

Colored ones are quite expensive so we started with monochrome

This is an amazing idea that I am coming across for the first time! I wonder if there is already some implementation of it for Kindle! Edit: just found out this project. https://github.com/pjimenezmateo/kindle-wallpaper

I built one of these with a kindle + rust - https://github.com/davidhampgonsalves/life-dashboard

The version of the e-reader is important if you want to access deep sleep / RTC for lower power usage.

Here's hopefully some constructive feedback: Showing the battery state in Volts is almost completely unhelpful because of the non-linear discharge curve. An approximate of the battery capacity is more useful (even if not perfectly accurate) than the voltage itself.

You're right, it's on our list for updates
