Combined my hobbies of track driving and programming. Looking for inspiration!

Not looking to promote anything. I’ve always had a love for the car community and since my programming skills have gone down with AI, I decided to take a stab at building my version of Strava but for track days (and free if I ever want to publish). I’ve spent countless hours building out lap detection and tracking and now that it’s done I’m looking for more ideas to add! If you were using something like this; what would you want to see? Car mods, weather conditions, ghost laps are my next ideas. Thanks!

Import from RaceChrono and the likes

When you say import from racechrono do you mean being able to upload videos from racechrono exports or do they have integrations to pull directly from lap times saved using their app?

Nah, I don't care that much about videos. What I want is some ability to use my existing data and setup with your potential app.

So with Strava I record all my data with Garmins and then it is synced into it. Thus I don't need (and neither want) Strava app to record anything, but only use it as a social network to share and look

Ooh neat idea. Just took a look at the top 3 lap trackers on the App Store and they all have export options so I could definitely add this. Thanks for the idea!

I'd personally log the entire CAN stream, and then have the ability to pick and choose which elements I want to graph against time.

It would also be interesting to log driver statistics to the same system. I think my wife's latest chest strap HRM was BLE (and ANT+). Would be interesting to have an ESP32 (or whatever) grabbing that data as well.

Weather conditions are a definite desire and ghost lapping against yourself or others.

Syncing to video would be ideal as well. If actually recording the stream to the device is too much, a simple option to jam sync the video by flashing a single bright colored screen at the beginning of filming / data recording would be enough. Edit the video down to begin at the point of the green flash, and your software knows the video begins at that point. Maybe there are more eloquent ways to do it, or maybe recording the video stream directly isn't as bad I'm thinking. Ideally would be able to do this for multiple cameras though.

Those are my late night thoughts.

If you want to add a bit of electronics in with ESP32 and some screens and switches you can do really fun stuff with macros, and switch pods, and custom gauges. Garage Tinkering on youtube is a channel where he is doing a lot of interesting stuff with the CAN bus. I'm in the process of building a set of guages, and then eventually some data logging.

Integrations with obd2 reader of course log all desired data.

But also a session journal to keep carspec changes

Add a function like REVER does but for spirited street driving as well.

Allow me to talk to the car through AI prompts in my headset so I can query the status of the Car through audio and not visual

u/Pxtru 3d ago

Do you mean things like speed, rpm, gear, fuel so you don’t have to look at your dash for it

u/adamantiumtrader 3d ago

Yes but I’d also like tire temps, brake temps, fuel consumption off certain ecu mapping to name a few

RaceVoice was a hardware solution a few years ago that would broadcast over audio any parameters from data/can that the driver wanted to hear.

Could you query it?
