BSides San Diego 2024 ESP32-C3 Badge

ESP32-C3 BLE rock-paper-scissors conference badge

Somerset Recon's post-event source archive says 400 badges were distributed at BSides San Diego 2024. It documents a custom ESP32-C3 conference board with a Bluetooth LE rock-paper-scissors game, high-level Wargames-themed UART and SAO CTF context, and KiCad, Gerber, BOM, and Arduino-style source material. The README also distinguishes the conference units' earlier firmware from later archived source behavior.
