This is a very basic try to bring github's calendar to hardware. Who wouldn't like to get up and look at the glorious contribution history of the path?
(not my calendar btw ☺)
introduction
Since I'm a student, manufacturing cost need to be low, why I decided to use three 10cm x 10cm pcbs and solder all components by hand. Because it is cheaper using one mutli-purpose board than two specific pcb designs, I decided to do so, not assemblying unnecessary components on these boards.

Questions
How big is the GithubHW PCB?
It measures 99.7 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GithubHW use?
146 parts, built around the TPIC6B595N. 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 GithubHW KiCad files?
From the raspyweather/githubHW repository on GitHub, at the commit this page was made from: the board is githubHW.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the GithubHW design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
