I have this idea in my head of creating a programmable sign that would rotate through various text-based messages. But rather than the usual scrolling LED sign, I am more envisioning something that would show the whole message at once. The use-case here is a sign somewhere in the 12-15" range (larger would be better) that would hang on a wall and display various inspirational quotes. Also do not want to have to run anything larger than a RaspberryPi to drive the display.
To me, the ideal display would be one based on e-ink technology. Low energy requirements, no need for fast-changing displayed information, etc. However, I have been unable to source any displays that would be large enough and reasonable in price. I could go the easy way and pick up an Amazon kindle, but again none seem to be large enough.
Alternatively, this could be done with a decent-sized digital photo frame, and then converting all the text into images.
I am throwing this out there to see if anyone has thoughts about how this idea in my head could be made a reality.
