I’ve tried to build my own (weather) display from an (old) kindle … but you have have the right model and the right firmware.
A view days ago I stumbled across this crowdfunding e-ink display. Looks very promising, I hope that I can finally build my (weather) display with it. (I would use a mounted TFT, but exactly on this spot I don’t have any outlet anywhere near, so I hope this will run of a powerbank für 2-3 months)
