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.

iFixit SAO (DEF CON 34)

Maker-documented ATtiny1604 soldering-challenge Simple Add-On

NerdFlare's public repository describes a 2026 iFixit Shitty Add On (SAO), while its repository description labels the project an iFixit DEFCON 2026 SAO. The commit-pinned README documents a physical PCB art badge with multiple LED animations, an interactive surface-mount soldering challenge, user-programmable firmware, an ATtiny1604-SS target, PlatformIO/Arduino code, and KiCad design files. A dated July 18 source commit says "Version 0.1 - FINAL: art, code, and PCB. 1000 made for DEFCON34." Those are direct project-publisher statements sufficient to retain a distinct pre-event DEF CON 34 artifact, but not proof of organizer issuance, iFixit corporate publication, event authorization, attendee allocation, actual handoff, admission function, a final unit-by-unit configuration, or reusable-image rights.
