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.
You will kill the battery if you never put it through charge/discharge cycles. If it's always plugged in eventually it will balloon and be a danger.
Good to know, I unplugged it after a similar comment and will plug it in when we're using it. Might eventually set up a timer or something, but to be honest, it doesn't need to be on except when we're cooking. Makes sense just to plug it in then.
I tried this for a bit but I can't stand having to touch it while cooking. We went back to a 3 ring binder with printed out recipes because it's so easy to print them from our phones. And when I say went back I mean I never printed recipes in my entire life and I'm going back to something similar to what my grandparents did writing recipes in a notebook. Touchscreens don't have a place in the kitchen for me outside of wearing a smartwatch.
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It's an old Samsung tablet, the OS is probably half a decade or more out of date.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.
