IRL @ comma HQ in San Diego, CA
The hackathon that brought you ChatPID is back! Join us at comma HQ for a weekend of hacking on the present and future of openpilot — cars, bodies, and anything else you can strap a comma four to.
We'll have comma fours, prototype body v2s, eGPUs, and food. Just bring a laptop, your favorite agent, and some good ideas.

FAQ
Do I need a car? Nope.
What should I bring? Your laptop and any hardware you want to hack on. We'll provide food, drinks, Wi-Fi, and any comma hardware.
What kind of projects will I work on? That's up to you! Hack on the UI, strap a comma four to your drone, bring your car to port, or anything else openpilot-related.
How are projects judged? Demos on Sunday afternoon, judged by the comma team on quality and creativity.
I've never used openpilot. Can I still come? Absolutely, though it's best to clone it and play around with it beforehand.
