The SAINTCON 2019 Enigma Badge was a two-board electronic conference badge shaped as a segment of an Enigma rotor, combining a curved RGB LED matrix, lampboard LEDs, 26 buttons, plugboard wiring, minibadge-holder support, and badge-to-badge connectors for a cooperative ring challenge.
Lifecycle
The creator write-up says each badge represented one of 26 rotor notches and that attendees connected rings of 26 badges to receive and advance challenge messages.
The write-up documents special Commander badges used by SAINTCON Committee members to help Agent rings progress through later challenge stages.
Attendees visited a Hut 6 station with a teleprinter-style receipt printer to receive intercepted messages for Enigma decoding.
The badge used a bottom connector for minibadge holder boards, I2C port expanders, individual minibadge power control, and chaining of up to eight boards.
The README documents STM32CubeProgrammer DFU flashing, separate STM32 and FPGA HEX files, TEST-pin bootstrapping, and first-boot test mode.
Operational history
Surviving-badge owners should preserve state before using the documented post-event firmware path or DFU flashing workflow.
