SourceIt adds a fresh Southern California Security BSides electronic-badge record to the worldwide compendium and preserves a primary official field guide while the challenge page is live, without copying its copyrighted Google Sites imagery.
The official badge-challenge page identifies the badge as a Cyberpunk Bunny PCB powered by an ESP32, with onboard accelerometer shake input, D-pad buttons, bunny-eye lighting, BLE behavior, and enough onboard logic to run challenge modes. It does not publish schematic, BOM, PCB files, battery details, production count, firmware source, or exact ESP32 module revision.
The official guide describes a portable CTF with a 10 percent chance of a mystery encrypted message after shaking, D-pad selection for decryption methods, Basic Tier classic ciphers, Advanced Tier Base32, XOR, AES-128, and ChaCha20 challenges, Bluetooth LE co-op interaction with nearby attendees, and a hidden shaking-sequence Easter egg for an ultimate flag.
The event page brands the 2026 edition as America's Finest BSides, while the FAQ places it at San Diego State University's Montezuma Hall and Theater. The badge page says Electronic Cats would be in the Villages for badge questions or help.
