I am trying to build something similar. I have a raspberry pi zero W, a 7.5 inch e-ink screen and some power electronics from adafruit. Have to find a good keyboard and figure out how to build a case. I am looking to build something more portable and something with a cleaner design (no open wires/cables etc). An important design problem is how to match a 7.5 inch screen with a much larger keyboard. There is the design here, with a screen stuck in the middle of a large board - not very pretty looking. There is the https://getfreewrite.com/ https://getfreewrite.com/ way, which is aesthetically more elegant, but the angle and location of the screen seems worse from an ergonomic perspective. Does anybody have a better idea?
