Jef's Library
Open schematics, code, and resources — free to use, build, and remix.
A registry of things I’ve built and am giving away: hydroponics and sensor hardware, firmware, schematics, sheet music, printable models.
Some entries are hosted here; most point at a public repository. Every entry names its licence, and everything is free to use, build on, and remix.
