10th-edition electronic badge
BruCON's 10th-edition electronic badge, documented as a schedule, venue-map, reminder, alcohol-sensor, and public ESP-IDF/KiCad badge project.

BruCON credits Jean-George with the electronic badge idea and design.
SourceBruCON 0x0A adds a Belgian security-conference badge line and captures badge work as an event anniversary project, including all-night soldering, app-style utility, server-side schedule sync, and public source release.
The event retrospective confirms an electronic badge with an alcohol sensor, and the public repository includes KiCad project files, generated Gerbers, Nokia 6100 LCD configuration, alcohol-sensor ADC and battery ADC configuration, and ESP32 footprint context. Component claims should continue to track the schematic and PCB files rather than attendee memory.
The repository README points builders at ESP-IDF and preserves the tagged con firmware release; the tree includes badge firmware for LCD/menu/schedule/map/Wi-Fi/URL behavior plus small PHP/MySQL server scripts for enrollment, nickname, alcohol-sensor, and Sched-derived schedule JSON endpoints.
BruCON credits Jean-George with the idea and design, describes organizers staying awake all night soldering badges, and the repository keeps the practical con build visible by linking the firmware release that shipped on attendee badges with its bugs preserved.
Lifecycle
The server tree records the PHP/MySQL workflow around badge enrollment, nicknames, alcohol-sensor data, and schedule JSON generated from BruCON's Sched export.
SourceThe badge is documented as updating the schedule, showing the venue map, and reminding attendees about talks and workshops.
SourceThe repository README links the BruCON0xA release as the firmware version installed on the conference badge, preserving the shipped build rather than only source head.
SourceThe repository preserves the KiCad project, board files, schematic, generated Gerbers, and position files needed to study or reproduce the badge PCB.
SourceOperational history
The Belgium record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
This preserves the operational reality behind the badge, not just the attendee-facing utility.
The archive should treat the tagged release as historically important even where later source changes may differ from the build attendees actually used.
The dossier is now stronger than a first-pass retrospective record while still keeping component lists tied to inspectable files.
