MNSEC 2026 Event Badge
ESP32-C3 Wi-Fi stamp-passport badge for MNSEC13
An MNSEC 2026 (MNSEC13) event badge documented through a user-guide deck and front and back board renders uploaded on September 28, 2026 by the Beelog maintainer of the MNSEC 2025 badge archive. The guide, headed MN CERT/CC 2026, describes a badge that joins the MNSEC Badge Cloud over event Wi-Fi, shows booth stamps, a contact card, and badge status, and reacts with light, sound, and vibration; its Stamp Passport collects stamps from 14 sponsor booths for a prize draw.
