Country dossier
Worldwide badge coverage for China, grouped into seeded badges, event editions, add-ons, operational issues, resources, and evidence sources.
Seeded artifacts
A conservative official-archive record for the special-edition HITB2018PEK badge at JD-HITBSecConf2018 Beijing, with Badge Village evidence for secret features, mini-games, hidden challenges, open-source intent, and MTK-series hardware notes.
A Grand Idea Studio badge for the first official international DEFCON edition, built as an artistic flexible-substrate PCB with 32 LEDs, USB connectivity, accelerometer input, role-color artwork variants, and a task-completion tree-lighting game.
Events
The October 29-November 2, 2018 first HITB Security Conference in China, whose official CommSec Village page documented a special-edition HITB2018PEK badge with Badge Village hacking support, mini-games, hidden challenges, and MTK-series hardware notes.
The first official international DEFCON edition, whose Joe Grand-designed flexible PCB badge used a tree-lighting game, USB, accelerometer input, role variants, and open design files.
Lifecycle
The Badge Village promised secret feature unlocks, mini-games, hidden challenges, and help getting started with reprogramming the HITB2018PEK badge.
HITB lists 'Are You Human Or Are You Hacker' under What's On the Badge for the special-edition Beijing badge.
Attendees illuminated roots and branches of the badge's tree by completing conference tasks, with completion turning the badge into a sparkling tree display.
The badge used a flexible substrate PCB with ATmega328P control, accelerometer input, USB serial, CR2032 power, and 32 LEDs driven through shift-register logic.
The official CommSec Village page says the special-edition HITB2018PEK badge was based on an MTK series platform with 32M flash, 128MB RAM, a display screen, and UART provided.
Grand Idea Studio published shield and breakout documentation, Gerbers, OSH Park links, and Arduino Uno source so attendees could isolate and hack the flexible badge hardware.
The official workshop slides documented guided hacking paths for attendees working with the flexible-PCB badge and related hardware.
Operational history
The record does not imply a universal public visitor badge or a known production run.
The public badge page, image archive, and API now point at a real upstream badge photo with source URL, license, attribution, and processing notes preserved.
The entry remains source-backed and image-free rather than copying event imagery, screenshots, social-media photos, or generated placeholder art.
The dossier records the public hardware notes and challenge surface while avoiding unsupported firmware, schematic, exact-chip, or implementation claims beyond the official page.
