GigaGeiger Badge (DEF CON 33)
Independent ESP32-S3 Wi-Fi monitoring and foxhunt badge sold for DEF CON 33
HackMy*'s maker storefront labels GigaGeiger a Wi-Fi badge for DEF CON 33 and shows a USD 120 price with a sold-out-since-August 6, 2025 state. The same listing describes a retro Geiger-counter-inspired device with a single rotary dial for 2.4 GHz channel monitoring, MAC-address foxhunting, and browser-based firmware flashing; it says the product shipped with a lanyard and batteries. Its linked public Penzz-HM repository publishes an MIT-licensed Arduino/C++ implementation for an ESP32-S3-WROOM, GC9A01 display, rotary input, Wi-Fi scanning, promiscuous-mode packet counting, RSSI tracking, and a local web updater, plus firmware binaries, Gerbers, and enclosure STL files. A separately published GigaGeiger PCB project on PCBWay is dated June 25, 2025, names Matt Wagner, provides Gerbers, and is marked CC BY-SA. These sources establish a real independent 2025 BadgeLife artifact and a public design trail, not official DEF CON issuance, admission, a completed event handoff, a complete electrical specification, universal radio/OTA safety, or a rights-cleared hero image.
