I actually had the most hilariously bad idea on how to make a TPMS system work.
There's various aftermarket TPMS setups of varying quality, but most of them output to an LCD or LED display with 7 segment digits. So you just have to solder the terminals driving the 7-segment displays to a multiplexer and have a chip read that! |

One way or another, for the price of the Stack TPMS setup, I can get a lot of cheap aftermarket TPMS stuff to try to reverse engineer. ;)

Well sure, I don't see my emphasis ever being trying to make money from the electronics side so after I lathe my square tuits (... yeah, sorry, I think I'm funny) I'd be happy to share my terrible code for free rather than getting stuck trying to support a paid product using it. ;) I found a couple sources of people who did reverse engineer OEM TPMS signals for various things, so it's obviously not impossible, it just remains to be seen if I'm competent enough at that sort of thing.
