Does anyone know what device is used to change image on e-ink pricetags? I know that there are some wireless ones, but I imagine that wired should be cheaper and better for hacking.
Those pricetags are pretty cheap. And on Ali Express they sell those 3 color ones. Maybe it would be possible to use them to make some fun keyboard?
