Last year I decided to jump into sim racing. I'm in my 40s, but it's something I'd thought about for years, going back to playing racing games on a keyboard or a controller. I picked up a wheel for my Xbox and fell straight down the rabbit hole. Looking at other people's setups online, I noticed the telemetry dashboards everyone used relied on a gaming PC, or a PC sitting in as a proxy (SimHub). That got me wondering whether I could build one myself, with no PC involved, connecting straight to the console. I'm a software developer, and I'd had a Raspberry Pi and the official 7" screen sitting in a drawer for the better part of nine years. So I did the developer thing and built my own.
Short walkthrough if you'd rather watch than read (about 3 minutes, music, no voiceover): https://youtu.be/AbCpE6qX7hk
It reads the telemetry your game already broadcasts over your network, with nothing installed on the console and no pairing. Live dashboard next to the wheel while you drive: gear, RPM, sector colours, tyre temps, proximity to the cars around you. The layout switches itself by car class and session type.
It started as just a dashboard for me, but it kept growing. Now when a session ends it grades how you drove (against your own past, not a leaderboard) and writes up Race Engineer Notes: where the pace actually was, which corners cost you, the laps you binned and why. I recorded the tracks myself by driving them (left edge, right edge, racing line), so the notes can say "you ran wide at Maggotts" instead of "49 seconds in." No AI is involved in any of that. It's all from the session data. But if you do want AI feedback, it'll bundle everything into a prompt you can paste into ChatGPT / Claude / whatever you use.
There's a companion for your phone too. You scan a QR code on the dashboard and it opens in your browser, no app to install. Session history, driver profile, trophies, and the track editor for naming corners. Everything stays on your own hardware, on your own network.
Games right now: F1 25 / F1 2026, Project Cars 2, Forza Horizon & Motorsport. I've added Gran Turismo 7 using info from open-source projects, but I play on Xbox and can't test it, so if anyone on PlayStation fancies trying it and telling me what breaks, that'd be hugely appreciated.
It's free, no subscription, no account, open source (MIT). Everything's here:
It's a hobby project built in the evenings around family, so it's not perfect, but I'm really happy with where it's got to, and I'd love feedback, ideas or bug reports. Happy to answer anything about the hardware or the games.
