Okay so I've been thinking about that Motherboard tractor hacking story (March 2017 article, https://motherboard.vice.com/en_us/article/xykkkd/why-american-farmers-are-hacking-their-tractors-with-ukrainian-firmware; Feb 2018 video, https://www.youtube.com/watch?v=F8JCh0owT4w) and how hella cyberpunk it is

@nev
oh, I'm actually working on this very project! Lots of CAN bus inspection, I can say that much.

@marlyn whatttt that's so cool! What exactly are you making?

@nev
I'm working as part of a small group to decode the various signals that come from each Control Unit (In automotive terms these are the E(ngine)CUs, but in a system such as a tractor these control units are often subdivided further and even more specialized, like specifically for transmission, or arbitrating the other control units) - the project itself is fairly open-ended, and small in timescale, but we aim to reverse-engineer the signals needed to authorize new components and perform other tasks that would otherwise require a John Deere technician.
