A Swiss Area41 2018 conference badge with an ESP8266 WiFi chip, display, web-based name configuration, LCD nickname display, Area41 schedule app, WiFi-scanning behavior, button-order Easter eggs, and public Proteus firmware.
Lifecycle
Compass reports WiFi scanning behavior and Easter eggs triggered by pressing badge buttons in specific orders.
The Compass wrap-up says attendees configured the badge by connecting to badge WiFi and entering a username in a web interface.
The Proteus README says PlatformIO builds a binary that could be placed into the firmware folder of a TECT installation for OTA installation.
The Compass wrap-up says it was possible to play sound from the badge by soldering headphones to the RX pin.
Compass reports installed apps for showing the attendee nickname on the LCD and viewing the Area41 schedule.
Operational history
The hardware section intentionally avoids component-level claims beyond public sources until an original hardware archive or transcript is recovered.
The record remains source-backed and image-free rather than copying blog, social-media, or repository imagery without complete provenance.
The dossier presents the badge as a real Area41 2018 artifact while keeping image rights and distribution-depth claims narrow.
