Another use for an old tablet
(slrpnk.net)
This one is nothing fancy, but it fit our workflow well. My SO has always saved recipes to a pinterest board - normally she brings a laptop to the kitchen and sets it up on a chair.
We finally took this tablet (came from corporate ewaste) and stuck it to the wall. It's too old for most apps but it seems to work well for this. We installed pinterest, and a podcast player. Eventually I'll check if there's a good replacement OS for the expired android version, but I figure we'll do a bit of a trial run, see how it's working for us and what we need, before starting with that.
There are some battery managers in linux which prolong the life of the battery by only charging it to ~40—50% capacity (which doubles the lifetime). If the tablet is mounted on the wall, then it might as well have continuous power and a power management app (if that exists on whatever platform the tablet runs).
It's an old Samsung tablet, the OS is probably half a decade or more out of date.
That implies Android. There is a FOSS app that requires AOS 4.0 or greater which cuts off the charging when the battery reaches a user-specified level:

I would generally suspect that app to require root, but there is no mention of a root access requirement.
EDIT: just tested this and indeed root access is required (#fdroidBug). So @JacobCoffinWrites should root the tablet to extend the battery life.
I'd been thinking about replacing the OS with a supported open source one anyways. I'll check out the xda forums and see what I can do, it'll be good practice for if I ever want to do the same with my phone.
