Station 562 Badge (DEF CON 34)
Independent BLE number-station puzzle badge for DEF CON 34 on CodeCell ESP32-C3 and XIAO ESP32-C6
Station 562 is an independent DEF CON 34 BadgeLife badge. The maker's public announcement describes a proximity-controlled badge with a BLE number-station puzzle, red-versus-blue proximity game, autonomous social/dance mode, expressive BLE MIDI instrument, tamper-evident mode, Setup menu, and optional hardware CTF, about 55 units made, and signed firmware with a key pair per badge. A release repository created on August 2, 2026 publishes the V6.3.0 final production firmware as binary bundles for two targets, a CodeCell ESP32-C3 build with 16 RGB LEDs and a Seeed Studio XIAO ESP32-C6 build with five PWM LED channels, both with an SSD1306 OLED and a VCNL4040 proximity sensor, plus owner guides, a hardware pinout, and a six-stage CTF guide. A DC562 !CON presentation added on November 8 tells the build story and shows the badge on display at the DEF CON 34 Badgelife Museum.
