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.
Badge Pirates ESP32-S3 touchscreen conference badge with a later firmware path
The BSidesKC 2025 badge was a Badge Pirates fully electronic conference badge documented through public production and fulfillment updates: 250 fully assembled ESP32 touchscreen badges from PCBWay with 3.2 inch touch screens, Wi-Fi, SD card slots, customs delays, tariff impact, and post-event pickup or shipping handling.

Independent ESP32-S3 party badge with a scheduled DC33 BadgeLife drop
BigTaro's Tindie listing calls FightDystopia 2025 an electronic party badge, prices it at $150, and displays an out-of-stock state that says it has been sold out since August 11, 2025. The maker says it detects a user-defined list of BLE MAC addresses to give a heads-up about what is around the user; includes a CTF with Windows Vista-era throwbacks, hardware and software puzzles, unlockable bling and GIFs, two custom PCBs sandwiching a screen for a retro-TV aesthetic, an ESP32-S3-based fully-programmable claim, twelve RGB LEDs, a custom lanyard, and stickers. The DEF CON 33 Creator Events List independently schedules a Friday BadgeLife Community drop naming FightDystopia alongside Submarine and FrogStar. This establishes a source-backed independent 2025 electronic artifact and scheduled event association, not an official DEF CON credential, universal or completed handout, BLE detection mechanism, security or privacy assurance, firmware source release, party-benefit accounting, or reusable-image rights.
Unofficial electronic badge with a documented DEF CON 33 BadgeLife drop schedule
BigTaro's FrogStar 2025 project page calls FrogStar an unofficial DEFCON badge, and the DEF CON 33 Creator Events List schedules a BadgeLife Community Table 1 drop that explicitly names the FrogStar Badge alongside two other BigTaro artifacts. The maker page identifies a Raspberry Pi RP2350, 1.28 inch GC9A01 240 by 240 round LCD, two SAO V1.69bis ports, addressable WS2812B RGB LEDs, an infrared receiver, six buttons, frog-themed CTF and game framing, and a Firmware v1.0 UF2 download with a copy-to-flash instruction. A Tindie listing separately calls it an electronic badge and says it was a Defcon pickup preorder; a later Uberflux listing shows an $80 / seven-sold / 23-remaining snapshot, a DEF CON 34 drop label, and $11 USPS Flat Rate shipping. These sources establish a real independent electronic artifact and a scheduled 2025 event association, not a confirmed completed handout, official DEF CON issuance, admission, exact production count, completed later fulfillment, firmware source release, or reusable-image rights.
Independent ESP32-S3 Wi-Fi monitoring and foxhunt badge sold for DEF CON 33
HackMy*'s maker storefront labels GigaGeiger a Wi-Fi badge for DEF CON 33 and shows a USD 120 price with a sold-out-since-August 6, 2025 state. The same listing describes a retro Geiger-counter-inspired device with a single rotary dial for 2.4 GHz channel monitoring, MAC-address foxhunting, and browser-based firmware flashing; it says the product shipped with a lanyard and batteries. Its linked public Penzz-HM repository publishes an MIT-licensed Arduino/C++ implementation for an ESP32-S3-WROOM, GC9A01 display, rotary input, Wi-Fi scanning, promiscuous-mode packet counting, RSSI tracking, and a local web updater, plus firmware binaries, Gerbers, and enclosure STL files. A separately published GigaGeiger PCB project on PCBWay is dated June 25, 2025, names Matt Wagner, provides Gerbers, and is marked CC BY-SA. These sources establish a real independent 2025 BadgeLife artifact and a public design trail, not official DEF CON issuance, admission, a completed event handoff, a complete electrical specification, universal radio/OTA safety, or a rights-cleared hero image.
Independent IR game/TV-control badge and Sheriff SAO combo listed for DEF CON 33
BigTaro's Tindie page calls Gunslinger-B-Gone an electronic badge with laser tag, a TV-B-Gone, a CTF, and an included Sheriff SAO; the page shows $100 and says it has been sold out since September 13, 2025. A separate Hacker Couture DEFCON 33 Product List independently lists a Gunslinger-B-Gone Badge by BigTaro at $140 and describes laser-tag play with the Sheriff SAO, making friends' badges light up, pointing an IR blast at a TV to power it down, CTF challenges, bling modes, Drinking Roulette, and a fully-programmable claim. BigTaro's Sheriff guide identifies the Sheriff companion as an RP2040-chip board, documents a CR2032 or LIR2032 battery holder with magnet and sticky pad, an independent battery switch, a standalone/wearable configuration, and an optional soldered SAO connection to the Gunslinger with the notch side up. These sources establish a real independent electronic-badge combo and a 2025 DEF CON vendor-list association, not a BadgeLife drop, official DEF CON issue, admission credential, complete IR or electrical specification, confirmed vendor handoff, firmware source release, or reusable-image rights.
ESP32-S3 LoRa mesh communicator badge

First electronic badge in summit history
Red Team Summit's official history identifies the March 11-12, 2025 Redmond event as the first Red Team Summit with an electronic badge. The same historical record gives 194 attendees, 61 organizations, and 108 CFP submissions, but does not describe the badge's physical form, technology, maker, or recipient scope.
Independent 25-slot Simple Add-On host badge; later DEF CON 34 roster continuity
Coruscant Ventures' official SAO Many SAOs Badge page identifies the object as a DEFCON 33 product, presents it as a 25-design Simple Add-On display platform, and says its outer LEDs require the separate SmartAO SAO. The maker's public technical README says the badge has two pre-installed 18650 batteries, USB and barrel-connector power/charging paths, up to 25 SAO slots, and an approximately 300 mA at 3.3 V total SAO budget when using charged batteries. A July 2026 public DEF CON 34 Badgelife response marks SaO MANY SAOs as Update to Existing, gives an $80 price and Venmo acquisition note, and repeats 25 SAO slots plus a 360 by 360 mm size. The current roster does not identify a changed board or new revision, so this is one independently documented DEF CON 33 host badge with a later availability/continuity record, not a duplicate DEF CON 34 artifact, official credential, completed sale, confirmed delivery, or rights-cleared image.
Independent electronic badge and Pirate Flag SAO bundle with a scheduled DC33 BadgeLife drop
BigTaro's Tindie listing calls this the Submarine Badge & Pirate SAO and describes a $150 Defcon-pickup preorder. It frames the electronic artifact as an interactive underwater world with CTF package deliveries in DEF-SEA, pirate battles, underwater cults, Atlantis, hardware/software puzzles, and soldering challenges. The source says it has a super-bright round display, more than six buttons, one SAO port, exposed extra GPIO, a fully-programmable claim, an exclusive Pirate Flag SAO bundle, stickers, and an interaction with Gunslinger-B-Gone. BigTaro's own Submarine page supplies a live dashboard-like maker surface, and the DEF CON 33 Creator Events List independently schedules a Friday BadgeLife Community Table 1 drop naming Submarine alongside FrogStar and FightDystopia. These sources establish a real independent electronic-badge bundle and a scheduled 2025 event activity, not an official DEF CON credential, confirmed attendance or handout outcome, production count, electrical design, firmware source release, or reusable-image rights.
ESP32 touch-wheel badge with TFT, audio, LEDs, and games
The THOTCON 0xD badge was a Fourfold-built electronic conference badge for the May 30-31, 2025 Chicago event, documented as a 2,000-unit ESP32 touch-wheel badge with ST7789 TFT display, buzzer, six LEDs, LiPo power, add-on header, games, visual effects, and challenge hooks.
Maker-stated DEF CON 33 multicolor-LED Simple Add-On; 2026 leftover pickup only
coryallegory's live Uberflux listing calls this the Vibe Coder Dog SAO, says Science Dog is now Coder Dog, and says the artifact was created for DEFCON 33. The same current listing says a few leftover units are available as a 2026 pre-order for pickup at DEF CON 34 or BSidesLV in Las Vegas. Its August 4, 2026 snapshot lists $15, five sold, and zero remaining, with a free Saturday August 8 BadgeLife Village pickup label. The maker says the unit is fully assembled, has a standard 2 by 3 SAO header, and uses cycling multicolor LEDs to light its keyboard with AI magic. This is source-backed evidence for an independent DEF CON 33-associated LED Simple Add-On, not proof of the original 2025 distribution, a specific controller or actual AI behavior, final 2026 pickup, DEF CON organizer affiliation, conference admission, or reusable-image rights.
Antisyphon-sponsored ESP32-S3 badge CTF
The Wild West Hackin' Fest Deadwood 2025 e-badge was the conference's electronic badge and badge CTF artifact. The official WWHF e-badge page identifies Antisyphon Training as the badge sponsor, Meta CTF as the scoreboard/challenge partner, multiple challenges solvable from badge behavior or firmware, and Ray Feltch, David Fletcher, and Rick Wisser as badge-team contacts.
