Show HN: I made a Raspberry with Qwen my local car AI

Found that you can actually run a 35B Qwen model on a Pi with very impressive intelligence and stability. Built connectors for car ODB to read all about car internals, and manufacturer's cloud service for stuff like changing AC or opening/ locking doors. Gave it info such as the full car manual. And then hooked it up with my other agents in our discussion room!

So now it can answer car questions such as "when should I add oil and what kind of oil?" and help you fully offline, and when online talk with the agent family that includes all the most powerful models so they know how the car is, plan new features and develop itself with them.

For example, if car breaks and can't move the car agent informs my agent family and they can already look for a suitable train ticket without me needing to check things or do something.

Cool — but is that model really the right choice for the task?

I guess it is only 3B active which helps a lot but is Gemma 4 E4B not more practical?

What's the hardware situation to get OBD data?

I'm currently integrating one for simple diagnostic readouts to integrated small touchscreen. The main goal being a retro looking display that mainly dumps ODB data/monitors, but also reads maps data to show a "waypointer" a la crazy taxi. (This is proving difficult)

Respectfully, I don't think this is....real?

-I mean, getting the absolute basic bits like diag codes converted from the odb 2 data to some program w/ a graphic interface is about as far as people get, if they can get passed the power and power on/off conundrums.

-If you get that far, How in the lord's name did you manage to seemingly....MITM the vehicles cloud service (climate/locks/remote start) using raspian or whatever? IE; how are you able to establish a TLS connection (yeah, like that lingo?) from the raspberry to the manufacturer API? I think the manufacturer would be interested, as you have functionaley made another key to the car.

-A more important question....what purpose does this serve? IE; the cloud connection/controller is in the car. I can't imagine it's easier to connect to the rasp shell (is it on 24/7?) to connect to the car app to turn on the ac.

- I assume you have one of the "big boy" ones with more WAM. THat said.....are you implying by saying "the pie can actually run qwen" that you are running it locally? if so.....erm...I need reciepts. Cuz idk what that even means nowadays.

Maybe i'm just jaded because my "crazy, crazy taxi style waymarker + ODB2" monitor isn't progressing, but this is...fishy

From readme:

"""

Unverified against the real car — it will confirm or refute itself on the next drive

"""

Looks like a ton of this is aspirational.

For your project -- do you really need the car's GPS positioning? Could go with a dedicated GPS antenna, like the freematics dongle
