PIC32 badge with LCD, IR, capacitive sliders, and public firmware
The RVAs3c 2014 badge was a redesigned HackRVA electronic badge whose official preview and public firmware source document a PIC32-based platform with LCD, infrared, capacitive sliders, LEDs, speaker, micro USB, and game/application code.
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.
Hand-built badge with USB reflashing and CTF challenge hooks
The RVA5sec 2016 badge is documented by HackRVA's official interview as a hand-built custom-firmware electronic badge with reused/improved hardware, standard USB reflashing, low-frequency serial-transmission experimentation, and CTF challenge hooks.
DePaul IRL ESP32 badge with capacitive pads, LEDs, speaker, and microphone
The THOTCON 0xA / Infinity badge was a Chicago electronic conference badge produced with DePaul's Idea Realization Lab for the May 3-4, 2019 event. DePaul Newsline reported a six-month, 1,700-unit custom circuit-board badge build; the public Poplicola repository documents a SparkFun ESP32 Thing Dev base, five capacitive touch pads, six LEDs, speaker output, microphone input, stock-firmware restore commands, and Arduino examples.
RP2040 audio, microphone, LEDs, and EdgeImpulse badge
BugCON 2022's Electronic Cats badge repository documents an RP2040 electronic badge for BugCON 2022 CDMX with USB serial access, LEDs, microphone, buzzer or speaker, a small machine-learning trail through EdgeImpulse, Arduino Mbed programming notes, KiCad hardware files, and Blink/AudioWAV firmware examples.
Music-and-airship CTF building badge
A Security Fest 2024 badge shaped around Gothenburg's Feskekôrka fish-market landmark, with piano/touch-key gameplay, an airship story CTF, LEDs, USB-C serial interaction, and documented attendee/speaker/crew variants.
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.
Sold-out independent three-SAO monorail badge for DEF CON 34
Zach's Hacks' live Shopify listing calls the Monorail Con Badge sold out and says preorder customers will receive pickup details by email, while noting there may be a few extras to trade in person. Its current public product payload marks all three purchase options unavailable: a $65 badge-and-SAOs option, a $150 bundle option that adds Dani.pink's separately made Laser* Tag Badge DS, and an $80 voluntary extra-payment option. The listing describes a small monorail on a track, a clip for a paper ticket not included, three SAOs, a speaker/mini-SD sound surface, blinky lights, and a regulated 3.3 V supply from two AAA batteries. The maker explicitly says final versions may vary and that it has no affiliation with the Las Vegas Monorail. This is a source-backed independent pre-event badge record, not evidence of final manufactured specification, fulfilled pickup/trade, included transit fare, common hardware/firmware ownership with the bundled Laser* Tag badge, DEF CON organizer affiliation, conference admission, or reusable-image rights.
