First Adelaide Wombat CTF badge with MS51FB9AE, LEDs, micro-USB, and soldering village
BSides Adelaide 2024's first Wombat badge is preserved through creator-published Hackerware and Hackster sources as a full-colour UV-printed CTF hardware badge with Nuvoton MS51FB9AE controller, CH340G USB serial, RGB LED, six challenge LEDs, CR2032 power, and attendee LED soldering.
ESP32-C3 BLE rock-paper-scissors conference badge
Somerset Recon's post-event source archive says 400 badges were distributed at BSides San Diego 2024. It documents a custom ESP32-C3 conference board with a Bluetooth LE rock-paper-scissors game, high-level Wargames-themed UART and SAO CTF context, and KiCad, Gerber, BOM, and Arduino-style source material. The README also distinguishes the conference units' earlier firmware from later archived source behavior.
Four-challenge serial CTF badge
The AvengerCon IX electronic badge carried a built-in four-challenge CTF, coin-cell blink behavior, BAT CON battery jumper, micro-USB connection, CP2102 USB-to-UART serial path, and post-event unlock codes published by the official badge page.
Standalone binary-entry CTF badge with tactile buttons, LEDs, and hidden hardware challenge
BSides Adelaide 2025's second Wombat badge is source-backed by Hackerware, Hackster, and attendee challenge analysis: it kept the MS51FB9AE/CR2032 LED badge line but added onboard CTF controls, seven official challenge LEDs, binary flag entry, and an unannounced hardware challenge.
Norwegian Security BSides SolaSec duck-shaped CTF badge
A source-backed Norwegian Security BSides electronic badge record: Noroff's post-event report documents a custom SolaSec electronic duck badge with seven LED challenge indicators, the official recordings page preserves Caleb Davis's Sykt Badge talk, and Cryptax's CTF write-up documents RP2040/MicroPython behavior, USB serial access, Wi-Fi AP setup, and on-badge web challenges.
Planned winnable CTF badge with an NFC game claim
The public DEF CON 34 BadgeLife roster contains a new listing submitted as Lockheed Martin - Aeronautics Cyber Range (ACR) for a badge titled SR-71. The named team says the badge is only winnable through a CTF it plans to host at its Aerospace Village booth and on its Discord, and describes a TCG-type card-collection game using NFC peer-to-peer and reader modes. That is concrete first-hand pre-event artifact evidence, while Aerospace Village's official page independently establishes the DEF CON 34 context; neither source publishes the badge's physical construction, NFC-hardware placement, or final distribution.
ESP32 portable CTF badge
BSides San Diego 2026 handed attendees a Cyberpunk Bunny electronic badge: an ESP32-powered portable CTF with cryptography challenges, wireless hacking, hidden secrets, an accelerometer-driven oracle, BLE co-op behavior, and an ultimate hidden flag path.
Madrid Hackplayers electronic development-board CTF badge
A source-backed Spanish hacker-conference electronic badge record: the official h-c0n post says Hackplayers finally produced an electronic badge for the sixth 2026 edition, describes it as a fully functional development board, and ties pickup to the February 6 conference registration and CTF start; the public `therealdreg/hcon2026hwctf` repository and Hackplayers post-event write-up document RP2350/RISC-V firmware, tooling, named co-creators, and winner write-ups.
