The official checkout calls the physical item a limited-edition LED badge. It does not identify a PCB, programmable controller, LED count/color, power system, firmware, radio, connector, or any other engineering surface, so the record preserves the narrow source classification rather than reconstructing electronics.

Compatibility: Puzzled Hackers LED Badge (DEF CON 34)

source-published interaction surface

Draft MechBattle menu and game code

The CPEC repositories publish menu, pilot-record, game-state, display, sound, and game modules, and the earlier repository calls its code a non-final second iteration. Those sources establish an in-progress planned interaction surface, not final gameplay, player outcomes, a completed CTF, physical controls, accessibility behavior, or a deployed event experience.

Compatibility: CPEC DC34 MechBattle Badge

source-targeted development platform

ESP32-S3 PlatformIO source target

The game repository's PlatformIO configuration targets an Adafruit Feather ESP32-S3 no-PSRAM board with Arduino and a LittleFS configuration. This records an intended development target only; it does not identify a final badge PCB, assembly, controller population, storage, boot flow, power design, or a manufactured event unit.

Compatibility: CPEC DC34 MechBattle Badge

technical preservation source

MIT Arduino, KiCad, Gerber, CAD, and fabrication archive

The DC32 repository publishes Arduino sketches, setup/compile/upload scripts, KiCad project files, Gerbers, CAD/fabrication material, a parts list, and assembly instructions under an MIT repository license. Its documentation also notes a then-precompiled CTF library, and no reviewed source establishes that every current fundraiser unit ships a specific repository commit or complete CTF source.

Compatibility: BTV Camera Badge (DEF CON 34 Fundraiser)

Piia Alavesa's public CyberSlayer app targets the Disobey 2025/2026 board with a ten-zone cybersecurity combat game, NeoPixel progress and combat feedback, and documented installation via mpremote or the official development-firmware loader.
