Questions
How big is the Automatic Bell Ringer PCB?
It measures 87 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Automatic Bell Ringer use?
10 parts, built around the BC547 and IR204-A-L. 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 Automatic Bell Ringer KiCad files?
From the mwiwa-fred/Automatic-Bell-Ringer-PCB-Design repository on GitHub, at the commit this page was made from: the board is Automatic Bell Ringer.kicad_pcb and its schematic Automatic Bell Ringer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Automatic Bell Ringer design in my own project?
Its repository states no licence, so its author keeps all rights: ask mwiwa-fred before reusing the design.
