A while ago I discovered someone made an e-ink Portal-inspired calendar. Well last week I finally caved, and bought all the parts to make my own!
This was my first foray into using an ESP32 (as well as soldering) so all things considered, I'm happy that it's running at all given my lack of skills in the areas.
If you want to make your own, the printables page has the models and a link to the GH with the code, BoM, and build instructions:
