Hand-built HackRVA PCB badge with IR, LCD, audio, and USB
The RV4sec 2015 badge is documented by HackRVA's official build post as a hand-built electronic badge with custom PCB assembly, surface-mount components, IR, audio, micro USB, LCD, and an optional reset-header development path.
ATmega32u4 tesserHack maze badge
The THOTCON 0x8 badge was a Chicago electronic conference badge built around an ATmega32u4, four RGB NeoPixel LEDs, three potentiometers, micro USB, two CR2032 coin-cell holders, and tesserHack stock firmware for an 8x8x8 maze game.
Singapore building-shaped serial CTF badge
SINCON 2023's first badge was a Khong Guan Building-inspired interactive CTF badge with a custom single-sided PCB, ABOV A96S174 MCU, CH340G USB-serial bridge, micro-USB, CR2032 holder, 12 MHz crystal, SMD passives, and 1206 LEDs.
UV-printed cyberpunk skyline CTF badge
A full-colour UV-printed Security Fest badge inspired by Gothenburg's skyline with a cyberpunk treatment, backside-mounted components, Micro-USB CTF interface, cryptography puzzles, and soldering-village LED personalization.
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.
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.
custom ESP32-S3 / LoRa Meshtastic badge
The BSidesSLC 2025 E-Badge is a source-backed custom electronic badge that BSidesSLC describes with an ESP32-S3-WROOM, LoRa, 25 addressable LEDs, TFT display, Micro-USB or three-AA power, mini-badge slots, and custom Meshtastic firmware.
Independent brass Coin M0 text-adventure and CircuitPython eChallengeCoin planned for DEF CON 34
AoSC's 2026 eChallengeCoin page describes a planned limited run of 40 brass electronic coins, framed as gifts for participants in its Choose Your Own Charity initiative rather than items for sale. It describes a Sara and the Missing Artifacts terminal text adventure, three groups of NeoPixels, a small speaker, one large touch pad for CircuitPython, no battery, 46-gram brass construction, and a Micro-USB serial connection; its form says a $100-or-greater youth-STEM-charity donation may receive a 2026 coin by U.S. mail or DEF CON pickup. The same page links the official CircuitPython Bradán Lane STUDIO Coin M0 profile as the build specifically for the eChallengeCoin. That profile identifies an ATSAMD21G1A, 4 MB flash, three RGB-NeoPixel groups, three capacitive touch pads, a speaker, and native USB-C. The linked primary sources therefore document a real planned independent DEF CON 34 electronic artifact while also disagreeing about USB connector type and touch-pad count; this record preserves the conflict rather than resolving it. They do not establish final manufactured-unit parity, confirmed donations or delivery, charity/tax treatment, official DEF CON issuance or admission, game-source licensing, or reusable-image rights.
Completed ESP32-S3 CircuitPython conference badge with public source
Carolina Code Conference's organizer documented Circuit Board Badge pickup for its August 14-15 event, and its named badge partner published a source archive for an ESP32-S3 CircuitPython board. The archive identifies five WS2812 LEDs, three buttons, a 1.77-inch ST7735S display, Micro-USB, and CR123A or USB power. It supports a released badge software and hardware reference, not a recipient ledger, an independently audited final production configuration, or a rights-cleared physical-badge image.
