Questions
How big is the Rusty hangulclock PCB?
It measures 45 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rusty hangulclock use?
15 parts, built around the 74AHCT125D. 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 Rusty hangulclock KiCad files?
From the suapapa/HangulClock repository on GitHub, at the commit this page was made from: the board is sch/rusty-hangulclock/rusty-hangulclock.kicad_pcb and its schematic sch/rusty-hangulclock/rusty-hangulclock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rusty hangulclock design in my own project?
Its repository states no licence, so its author keeps all rights: ask suapapa before reusing the design.
