Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The writeup documents multiple clue texts triggered by toggling DIP switches and pressing a badge button, turning a small hardware input surface into the puzzle selector.
Badge context
BOM listing the 69x43 mm board's ATmega32U4, USB-A connector, four-position DIP switch, two tactile switches, red/green LEDs, crystal, passives, and ISP header.
Zeta-Two field report documenting the challenge badge, HID/serial behavior, DIP-switch clue paths, prize flow, and community attribution.
Public hardware repository with board files, schematic/layout assets, firmware directory, and Gerbers for the challenge badge.
Source trail
Primary open-hardware source for board dimensions, design files, Gerbers, firmware directory, and component evidence.
Primary field source for challenge behavior, HID/serial lore, clue flow, prize context, Weckzen attribution, and Zkylark Electronics thanks.
