DIY audio-related projects of questionable quality and dubious utility; delivered in 30 minutes or less or the next one is free
When you download this as a ZIP open AudioThings.kicad_pro, this is a panopticon project that contains the main resources and exists to handle some references that are common. Apparently KiCad and I have some foundational disagreement on how to misuse their software; this is primarily because I'm ignorant, but also they have incorrect opinions.
