Questions
How big is the Unix wall clock PCB?
It measures 27 × 21.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Unix wall clock use?
9 parts, built around the STP16CP05T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Unix wall clock KiCad files?
From the dotcypress/unix-wall-clock repository on GitHub, at the commit this page was made from: the board is pcb/unix-wall-clock.kicad_pcb and its schematic pcb/unix-wall-clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Unix wall clock design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
