12F629. Click here for a full size schematic drawing(PNG).An eight pin PIC12F629 drives the 4094 shift registers that control each e-paper segment. Two pins are unused (GP4, GP5).

This drove the design towards an e-paper solution. However, large e-paper displays can be a bit pricy. That spawned a creative idea—why not grab four smaller displays and make a clock with ...

Unlike the Weasleys' clock, this one does not magically detect the location of its users, but must be updated via a special mobile app. You can update manually with one of the twelve locations ...

There are 1,440 minutes in a day, so Poem/1 needs to display 1,440 unique poems to work. The clock features a monochrome e-paper screen and pulls its poetry rhymes via Wi-Fi from a central server ...

The SoC design challenges that are addressed in this paper include scalable clock design methodology, reduced human efforts/error, adherence to standard design practices, soft errors, low power ...
