Little devices like this are popular amongst some Diabetics for displaying their continuous glucometer data (I built something similar using an eink screen and the Dexcom home assistant integration). It's fun to see what people use these for!

My mom recently found out she has diabetes, and doing something like this for her I think would make life nicer. How did you manage to build something like this?
Thanks for the insight. That's a really awesome use case: near real-time health tracker data.
I was gifted a Tidbyt. These gadgets are ok, not super useful. Just consumption for consumption sake
A LED matrix with audio and home assistant integration. ...what for?
I saw this use-case and was immediately interested. This hangs near my front door so I know what’s coming. This particular one has some limitations, but I think the low-res nature of this class forces some nice design decisions.
So... a screen
With really low resolution
And talking AI.
I guess it's cool, but why not a regular display? The LED array's 2:1 aspect ratio (128x64) is kind of constraining.
Because of style. Some people like this. A couple of years ago I'd have bought this because it's a neat looking gadget. Now I don't have money for these unnecessary items.
