don't you need to charge them eventually? so you end up taking them down a lot. they should think about wireless charging pads that can be installed into the wall for these sorts of things.

Sounds like a good idea. Just anecdotally I found it pretty fascinating that I bought a new Kindle some three months ago and it still hasn't run out of batteries (came with 76% and now at 16%). Admittedly I haven't been using it a lot though.

My experience with Kindles is that the battery drain is all about wifi - if you keep it in 'airplane mode' most of the time (except to send new content to it / return library books early etc.) it can last for months on a charge.

Very much on the DIY end, but I made a similar e-ink art piece that shows off the currently playing song on Spotify. I used a 3 colour display to add some flair :)

It’s not the easiest to set up yourself - need to generate Spotify API keys and build the unnecessary separate binary for dithering, but here’s the project if anyone is interested!

This is neat, but it looks like something the HN crowd would build themselves over buying. I know my first impulse was "I could make this..."

eInk/ePaper displays aren't cheap and getting them cheap requires buying pre-loved devices. The only way to drive down costs right now is bulk ordering. Unless your time is worth less than say $25/hr, this is likely much cheaper than building.

E-ink screens only consume power when refreshing so if you don't change the image a lot you won't need to charge it often

True, if the processor powers down too.

Most people are not really doing anything that important where they need to worry about their per hour time.
