Here's the github repo for this year's badge (there's a software-only badge simulator so you can kind of play around with it even without the hardware, although some of the multi-player things that rely on infrared badge-to-badge communication won't be any fun): https://github.com/HackRVA/badge2024 [1] Video of the 2023 badge: https://www.youtube.com/watch?v=KWZriUMNpLc [2] https://rvasec.com/

Because it's kind of a group project for the local hackerspace and it's evolved over a bit more than a decade (didn't always use rp2040, obviously).
