350 euros for 6 inch? 450 for 9 inch‽‽
Just buy some very cheaply-available electronic price tags [1] and use open-source firmware[2] which supports greyscale + yellow. Save literally HUNDREDS of dollars/euros/etc. For extra credit, they are not only black and white eInk screens, they are BWY, so they can add a splash of yellow!

- clash 5y agoIf you just want to display information, I agree. Black/White & red/yellow is enough. But if you want to display a photo, you need gray shades.
- HWR_14 5y agoVery interesting. Do you know of even bigger price tag models to search for? Is it as easy as the second page makes it seem? And, separate question, but I tried just scanning [2] and I'm having trouble understanding how to determine the resolution of the tags in [1].
