BSides Peoria 2025 HackTheBadge Challenge Badge

Maker-published one-off ESP32 badge-challenge device

A source-bounded independent BSides Peoria 2025 challenge-badge dossier. Technet8394's event-period public HackTheBadge README calls the work "My ESP32 code for the BSides Peoria Badge Challenge 2025." Its later source release documents an ESP32, a 240×320 ILI9341 TFT panel, two batteries, and wiring. BSides Peoria's official 2025 announcement establishes the October 25 Bradley University event, and its 2026 organizer retrospective says the prior edition drew nearly 350 people and had electronic badges. No reviewed organizer source links this specific maker project to a main attendee badge, official issuance, or completed handoff, so the catalogue keeps it as an independent event-associated challenge device.

FirstBuild / GE Appliances Washer/Dryer Badge (DEF CON 34)

Pre-event FirstBuild / GE Appliances 100-free-badge washer/dryer motion giveaway project

FirstBuild's official DefCon34-Badge repository describes an Arduino-compatible FirstBuild / GE Appliances washer/dryer badge for DEF CON 34. Its README names a current production target of an STM32G031F8P6 with an MXC6655XA three-axis accelerometer and eight SK6805 side-emitting RGB LEDs, driving an infinity-mirror water effect that follows gravity. The repository publishes firmware, a schematic PDF, an MIT license for software and associated documentation, and a distribution guide that says the project is intended to be distributed as firmware installed on physical badges. A first-person r/Defcon post reviewed on 2026-08-05 says its public-account author is returning with the GE Appliances booth in IoT Village, has another 100 free badges to give away, and plans an unspecified number per day; it calls the item a cartoon UltraFast Washer/Dryer Combo with a motion-responsive infinity mirror. In a comment, the author says the artwork, PCB design, and software were done in-house at FirstBuild. That account statement does not independently establish the author's employment, formal FirstBuild or GE Appliances authority, official booth authorization, final stock, or completed handoff. GitHub still shows no release or tag, and the record remains a separate event-associated pre-event project, not the official DEF CON attendee credential or an image-reuse grant.
