- Hacker News
- I will shamelessly plug https://pitstop.app. I've been working on this for years and I work on/race cars regularly.
I wouldn't fully trust LLMs with this :p BUT this project is still really freaking sweet.
by Robdel12 - 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?
by dofm - I think you should provide better use case scenarios that make clear why this project is useful.
I can already change AC and lock doors with two buttons, why it should be better to do it by voice? Pressing those buttons is way faster.
I guess the manual RAG is useful, what I am saying is that use cases aren't clear from your post or README. As it is, one reads it as "cool, LLM in a car", and skips it.
by fedeb95 - It's unfortunate that a 16GB raspberry pi is so incredibly expensive now. Fascinating how we've scope creeped over the years from the original $30 or $35 raspberry pi SBC to this.by walrus01
- 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
by Reubachi - I scanned this README looking for the part written by a human and gave up when I realized there wasn't one.
the Mermaid diagram doesn't even render.
- What's the point in having it use an offline LLM if it still requires an internet connection to send all your chat messages through the "Groupmind" paid service?
Seems like the real purpose of this project was to plug Groupmind and whatever else the author made.
by nacs - Fair warning, I have found local models and frontier models to be very bad at the specifics when it comes to cars.
Small differences like month and year model can impact oil capacity, oil weight and things like that, the details that matter quite a bit.
I found frontier models couldn't get things like what engine was in a 1994 Nissan Skyline, one of the more infamous and talked about cars on internet forums for decades, with dedicated fan databases that would have been scraped.
Questions like "what air filter do I need for my 1994 Suzuki Swift?" are hit and miss.
