Projects
Open source, mostly. Diagnostics and parts catalogues for cars whose manufacturers would rather you visited a dealer, plus the tools and libraries that fell out of building them.
Everything here is on github.com/emdzej.

A note on data
The catalogue and diagnostic projects ship without manufacturer data. None of it is redistributed, and none of the code is derived from it. You bring a disc you own, or point the tool at a tree you already have. See Right to Repair for why these exist at all.
