I found this guide to converting an old Kindle 4 to display anything from the web super useful. https://matthealy.com/kindle I bought another 3 used kindles for $20 each after getting it to work.
If this kind of device would come in 'off the shelf' ready to go, I'd buy one. I think e-Ink screens are really attractive to be hung on the wall. I hope we're going to see such device come to life; my bet is some successful kickstarter followed by an amazon clone with alexa built-in :vomit-face: +1 for a simple device that does one thing, and does it well.
Once they're cheap-enough, the manufacturers will come.

I'm super excited to see the price on panels beginning to drop. $200 for a 10" panel is, for an old guy, exciting. Once they're cheap-enough, the manufacturers will come.

Me too. I just looked at the Wave-share 12.78” Red/Black/White display, and they’re listed for $178. If I weren’t juggling 4 other projects, I’d pick one up. It’s cheap enough to support all kinds of projects.
eink displays are such a great media for calm tech. It is a shame that it doesn't go down to a reasonable price, otherwise there would be a ton of cool devices with use cases like this.
Mentions battery life but does not say in the end how long between recharges with the 12000mah battery. Would really like to know power usage and how long between charges and more details about getting the pi to wake up once a day then sleep the rest of the time. Because if my maths right a Rpi zero running normally would drain the battery in less than full day.
I would imagine it runs for a long time if you are only powering it on to connect to WiFi, grab weather data, render the screen, and then shut off. The PiJuice page mentions "intelligent on/off switch", but I didn't easily find any details. Hopefully intelligent means "turn on at a certain time via an onboard RTC, turn off when systemd says it's OK" and the userspace code implements that dance correctly. In the absen…
You could try setting the pins to Z state (floating) before turning off to see if it makes a difference.
If you have access to an oscilloscope you can also analyze what is going on in fine details.

You can book the machines/stations out for periods of time, using your library card/account.
You have to do a safety induction to be able to book the more dangerous tools.
They also sell materials, or you can BYO.
