MomBoard: E-ink display for a parent with amnesia

What a beautiful use of technology to uphold someone's personhood, and let them know they are loved, despite (and with regard to) a profound injury.

This reminds me of a desire I've had for a long time: a simple, wall-mountable eInk device that could be configured with a URL (+wifi creds) and render a markdown file, refreshing once every hour or so. It would be so useful for so many applications – I'm a parish priest and so I could use it to let people know what events are on, if a service is cancelled, the current prayer list, ... the applications would be endless. I'd definitely pay a couple of hundred dollars per device for a solid version of such a thing, if it could be mounted and then recharged every month or two.

That is super cool! I might need to build one of those. My family needs a way to keep the fridge calendar up to date with our digital calendar.

Are there any plans to have a version without the battery? It looks exactly like what I've been looking for otherwise.

Also, what country are the orders shipped from? US?

curious what your use case is without a battery. currently you could keep it plugged in, are you wnting NFC-powered etc?

Nothing spectacular, I just want to have a display by the door that shows various things I'd like to check on before leaving, like: which windows are open, outside temperatures, etc.

I don't want a battery because:

- although every X months is quite ok, I don't want the hassle of remembering to charge it (first world problems, I know)

- but I also have a fear of leaving devices with a battery plugged in for a long time / having to monitor for battery swelling or other abnormalities

I already have a classic battery-powered display which shows temperature info from some sensors and it's really convenient, but annoying when the battery is dead right when you need the info. Even if that only happens every X months.
