DEF CON 34 Silent Disco Badge

Maker-published physical silent-disco badge; organizer role and handoff unverified

LastZactionHero's public repository is titled DEF CON Silent Disco Badge and documents a wearable electronic badge that plays local DJ mixes, drives a music-linked light show, and syncs badge-to-badge over infrared. Its August 4 maintainer update says the boards were fabricated, assembled, and playing music, and that every badge's QR silkscreen points to the repository. The public archive contains KiCad design and fabrication material, firmware, and a MIT license, sufficient to record a distinct maker-published physical DEF CON 34-associated artifact. No reviewed DEF CON, venue, silent-disco organizer, sales, or handoff source establishes official issuance, a run size, recipient allocation, or completed event distribution.

Monorail Con Badge (DEF CON 34)

Sold-out independent three-SAO monorail badge for DEF CON 34

Zach's Hacks' live Shopify listing calls the Monorail Con Badge sold out and says preorder customers will receive pickup details by email, while noting there may be a few extras to trade in person. Its current public product payload marks all three purchase options unavailable: a $65 badge-and-SAOs option, a $150 bundle option that adds Dani.pink's separately made Laser* Tag Badge DS, and an $80 voluntary extra-payment option. The listing describes a small monorail on a track, a clip for a paper ticket not included, three SAOs, a speaker/mini-SD sound surface, blinky lights, and a regulated 3.3 V supply from two AAA batteries. The maker explicitly says final versions may vary and that it has no affiliation with the Las Vegas Monorail. This is a source-backed independent pre-event badge record, not evidence of final manufactured specification, fulfilled pickup/trade, included transit fare, common hardware/firmware ownership with the bundled Laser* Tag badge, DEF CON organizer affiliation, conference admission, or reusable-image rights.
