Questions
How big is the 8 minute buzzer PCB?
It measures 55.9 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 8 minute buzzer use?
15 parts. 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 8 minute buzzer KiCad files?
From the PhysicsUofRAUI/disruptivetech repository on GitHub, at the commit this page was made from: the board is 8_minute_buzzer/8_minute_buzzer.kicad_pcb and its schematic 8_minute_buzzer/8_minute_buzzer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 8 minute buzzer 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).
