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.
Attendee-assembled ESP32 DevKit / 1.8-inch TFT challenge badge
The public BSides Perth 2025 badge archive and its assembly documentation identify a physical, attendee-assembled custom-PCB artifact built around an ESP32 DOIT DevKit v1, 1.8-inch LCD TFT, four tactile buttons, headers, and Micro-USB power. The archive also documents a virtual companion and challenge context, but it was published in September-October 2025 and does not prove that every event attendee received the same physical configuration.

Completed independent RP2040 CRT-TV Simple Add-On
INSPECTRON 34 is an independent retro-CRT television-shaped Simple Add-On documented by its maker's post-conference public repository. The project records an RP2040, 16 MB flash, 1.14-inch ST7789V display, CircuitPython, USB-drive GIF loading, a DC34 right-port SAO design, and a completed DEF CON 34 run of about 20 sold boards. The post-conference handoff identifies V5 as the current released firmware. It is not an official DEF CON Human badge or admission credential.
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.
Spanish ESP32 PACMAN CTF badge with project-builder and community-reversal evidence
RootedCON 2026's PACMAN-themed attendee CTF badge is documented by both community reversals and a first-hand TechFrontiers project-builder write-up. David Melendez Cano reports original colored Ghost boards that attendees could choose, an ESP32-WROOM-32 platform, ESP-NOW game-server interaction, per-badge NVS identity/key material, and digitally signed questions and answers. Community reversals independently identify an ESP32-D0WD-V3, 1.77-inch ST7735 128x160 display, directional controls, and native quiz-server CTF protocol for the March 5-7 sixteenth edition at Kinepolis Madrid.
