This will be a work in progress.
I want a digital picture frame using a fairly large monochrome e-Ink display, and there’s… not a lot out there. Given my progress on a related project, I’m gonna take this on as a to-do.
My goal is for a low-effort frame that automagically updates with nice black and white art (think Ansel Adams) every 6 hours or so?
Here’s the parts list so far
I need to work out power. The beauty of e-Ink is that it takes zero power when it’s not being refreshed, so it just needs to …
- wake up every so often
- randomly pick from a large library of stored images on the SD card
- refresh the display
- go into a very deep sleep low power mode
Once it’s up and running, I don’t need any kind of wireless access, no active power draw for wifi or bluetooth! (I still like to have it available just in case … but will likely be disabled in daily use as a picture frame.)
I will need a battery to keep it running, and to periodically charge it… I’m thinking something like once every 6 months, ideally? Not sure what’s possible yet until I get deeper into the project… maybe any generic power bank with a micro-USB output should work?
