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.

BSides Peoria 2026 Planned Conference Badge

Planned Illinois Security BSides badge with sponsor-logo surface

A conservative planned Illinois Security BSides conference-badge record from organizer sponsorship material. The BSides Peoria 2026 call for sponsors says organizers are locking in badge runs, and the official 2026 prospectus includes a Logo on Badge sponsorship benefit. The official home places the October 24 event at Bradley University, but these pre-event sources do not establish a final credential form, electronics, ticket inclusion, allocation, or delivery.

Onion DAO 2026 Hardware Badge

Open ESP32-S3 Chicago builder-festival hardware badge

Onion DAO's official 2026 Chicago festival page says every accepted attendee gets a hardware badge at registration, with most components already on the board and a final soldering step. The same official site links to OnionDAO's public oniondao-badge repository, which documents a hacker-conference-style ESP32-S3 design, optional RF/audio modules, a display socket, secure element, expansion ports, and source trees for hardware and software. The public record supports a real organizer-published artifact and design, while exact recipient allocation, completed assembly, and final attendee population remain unverified.
