Recon Village's DEF CON 32 badge entry, The Recon Soldier, was a tactical-recon multi-layer PCB badge with red and blue LED eyes, 3D assembled design, and military helmet artwork.
Retrospectively documented independent ESP32-S3 electronic badge
Retia, LLC's public repository is currently named `DefconBadge2026`, but its immutable first source-release commit calls the project `DEF CON badge (2024)` and its README is titled `DEF CON Badge (2024) — ESP32-S3`. That source snapshot includes KiCad and fabrication material named `2024_def_con_badge_v1`, a badge photograph, and high-level hardware documentation. The official DEF CON archive identifies the 2024 event as DEF CON 32, so the record is attached to that existing edition as a retrospectively documented independent artifact; neither Retia nor DEF CON source reviewed here calls it an official Human badge, an attendee entitlement, or a confirmed event handoff.

South Korean closed-conference entry badge availability record
Zer0Con's official archive places the closed vulnerability-research conference at Fairmont Ambassador Hotel Seoul on April 4-5, 2024, and POC Security's official update trail described an Entry badge with 120 available seats before the archive marked the edition sold out.

ATtiny402 DeLorean PCB-art conference badge
An electronic PCB-art conference badge documented by its maker and badge sponsor, Punk Security, for BSides Cheltenham 2023. Punk Security's own dated event listing identifies its June 3 Cheltenham appearance as that year's badge-sponsor engagement, names a talk on building the BSides Delorean badges, and describes them as functional conference badges. The public `bsides-cheltenham-2023-badge` repository calls the artifact the Delorean badge, reports that parts sold for badge completion on the day raised more than £300 for Mind, and preserves EAGLE, Gerber, library, and Arduino firmware material. Its parts list names an ATtiny402, button, CR2032 clip, NeoPixel, and 3528 blue LED. The reviewed sources do not establish organizer-side 2023 confirmation, venue, production quantity, attendee allocation, individual handoff, final unit-by-unit configuration, completed assembly count, safety validation, or reusable image provenance.
Documented conference-badge-to-Wi-Fi-analyzer soldering activity
A public BSides Greenville 2023 event listing says the Circuit Board Medics Soldering Village would help participants solder and transform a conference badge. A contemporaneous BSidesGVL announcement says the conference badges could become Wi-Fi analyzers and identifies Circuit Board Medics as the team that designed the badges. A public attendee report after the event says that its author made a Wi-Fi analyzer at BSidesGVL. Together, these sources establish a real event-linked badge-conversion activity without identifying the original board or the resulting analyzer's components.

BSides Melbourne 2023 is represented by an official attendee-communications record proving badge and lanyard use for identity, access, photo-consent signalling, and personal interaction-protocol stickers.

Custom Game Boy conference game artifact
A custom H2HC 2023 Game Boy game badge/artifact distributed as a conference-themed game cartridge experience rather than a PCB electronics badge.
Taiwanese badge mini-games and card-reader conference pass
HITCON CMT 2023's official events page says the badge was more than an identification badge: card readers and mini-games were placed at booths and around the venue, attendees used their badges to activate and interact with them, and the Activity Team booth provided NFC card readers for hands-on inspection.
