E-Ink Clock

This contains the documentation of how I created a DCF77 synchronized E-Ink clock using the Rust programming language. The source code can be found on GitHub.

End Result

I do not have a nice case yet, but here is how the clock looks right now. Also, please ignore the horizontal ghosting lines, this is due to a bad contact on the FPC connector of the E-Ink display. At least I hope so. During prototyping I had to plug the display in and out several times, which unfortunately partially removed the copper on the display connector.

The E-Ink Clock in All Its Glory


Here you can see the prototype (with two missing MOSFETs, no RAM and a different way to generate the E-Ink voltages) on a breadboard:
