BSidesDFW 2026 Electronic Badge
Attendee-built ESP32-C6 Super Mini badge with 13 SK6812 LEDs and a badge mesh network
The BSidesDFW 2026 badge for the completed November 7, 2026 conference at the University of Texas at Arlington. The official sessions page invites attendees to build their badge in the Hardware Hacking Village and then figure out what it does, says it forms a mesh network with other badges, teases that somehow a MIDI keyboard is involved, and says it needs power from a USB-C device such as a phone or power bank, with a USB-C cable supplied. Designer Malcolm Galland published the KiCad design and Gerbers the night before the event as version 1.0, as manufactured for the con: an ESP32-C6 Super Mini module with 13 SK6812MINI-E RGB LEDs. The day after the event, the firmware followed in a separate repository that builds the badge mesh on Thread through OpenThread.
