DC-34 Countdown to Singularity Badge public source directory; release and support unverified

published firmware-development trail

The README points to an Arduino 1.8.5 firmware directory and says stock AVR chips need a one-time bootloader step before normal Arduino flashing. This preserves an implementation trail without reproducing programming commands or claiming a safe procedure, final fuse/programmer configuration, reproducible build, tagged firmware, deployed badge binary, recovery path, support, or warranty.

public independent DEF CON badge-project repository

eggsactly/DC-34-Countdown-To-Singularity

Public GitHub repository whose README calls it KiCad 6 design files for a DC-34 Countdown-To-Singularity DEF CON badge. The root exposes board, firmware, board-art, library, and BOM areas. It establishes a source-backed planned independent project, not an official DEF CON issue, production run, seller, price, allocation, delivery, final-unit state, or image-reuse grant.
