The lack of a battery kills this for me. Minimal power usage is one of the benefits of these kinds of displays, so it seems a very strange omission. We have too many cords running along walls as it is, and it makes the placement a lot harder.

Neat idea though.

I got into arduino when they first come out because I wanted to build information radiators. Every five years since I look at whether or when it will be possible to hang a picture frame on the wall that has no wires and updates. I’m just about overdue to look again. It seems like we are close, but charging it wirelessly or off of solar hidden in the frame is a while yet.

The desktop model really stands out here. The foot needs to be heavy, and there’s plenty of space for batteries in there.

I have a home made one running on a battery for 8 months. 10Ah, but it only updates every 8 hours.
