Questions
How big is the Weird generator PCB?
It measures 83 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Weird generator use?
73 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 Weird generator KiCad files?
From the pvar/pcb_weird_generator repository on GitHub, at the commit this page was made from: the board is weird-generator.kicad_pcb and its schematic weird-generator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Weird generator design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
