HackRVA badge artifact with badge-intro and CTF-room context
The RVAsec 2017 badge record is intentionally conservative: official RVAsec sources place HackRVA badge distribution in the 2017 layout and sponsor trail, and InfoconDB preserves a Badge Intro item, but this pass did not recover final component, firmware, schematic, or complete attendee-guide evidence.

Portuguese Security BSides electronic badge with badge-sponsor trail
A source-backed Portuguese Security BSides electronic-badge record: the official BSidesLisbon 2025 about page says the edition would have an electronic badge, the sponsors page lists a Badge Sponsor section for BitSight, and Eventbrite anchors the November 13-14, 2025 Auditorio FMD-UL conference.
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.
ESP32-C3/NFC electronic badge with first-party binaries and later public source
BSides Vancouver's official 2025 badge page calls the artifact an electronic badge, links its first-party programming bundle, and directs firmware information to a public project archive. That archive documents a 2025 REV 2 board and a public firmware refactor committed in 2026, so this record separates the completed 2025 artifact from the later source-tree revision.
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.
Singapore RP2350 and ECP5 FPGA challenge badge
NUS Greyhats' public GreyBadge archive identifies the 2025 GreyCTF badge as GreyMecha/Army, with RP2350-side CircuitPython firmware, KiCad hardware files, an ECP5U_25 FPGA schematic, GC9A01 SPI display, Li-ion power-path circuitry, summit UF2/filesystem releases, and named challenge apps.
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-C3 conference and CTF badge with SAO and IR pairing
NorthSec 2025's official badge repository documents an ESP32-C3-WROOM-02-N4 badge with eighteen NeoPixel RGB LEDs, five buttons, an IR pairing connector, two SAO v1.69bis connectors, USB-C or AAA battery power, and separate conference/CTF firmware builds.
Hackable electronic CTF badge with a source-depth caveat
A conservative PWNEDCR 0x08 record: a named post-event account says the October 18-19, 2025 San José conference used a hackable electronic badge as part of its CTF, with hidden Easter eggs and challenges. It supports the reality of a physical electronic badge but publishes no component, firmware, maker, production, or reusable-image documentation.
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.
Capable hardware, difficult camp history
The Dutch 2025 camp badge mixed ambitious hardware with late distribution, LoRa caveats, battery-safety controversy, and a documented pre-event team conflict.
Pre-event independent BENDER contest badge with activation pending
AND!XOR's source-backed DC34 5N4CK3Y project is an independent DEF CON BadgeLife contest badge with limited philanthropy units and a stated free-badge distribution route through challenges, contests, events, and other convention activity. Its official product page says BENDER hacking challenges and same-day activation instructions are scheduled for the event, but does not yet disclose the board or firmware implementation. It is a pre-event independent record, not the official DEF CON 34 Human badge.
Interactive ESP32 conference badge with screen, controls, badge-to-badge comms, and SAO support
BSides Ballarat 2026's public event page documents an Underground interactive conference badge designed and produced by Firnsy at Ballarat Hackerspace, with ESP32 processing, a screen, controls, badge-to-badge communication, SAO support, and a limited BSides SAO add-on; a public maker writeup also documents a third-party WS2812B Simple Add-On for the badge. In a March 2026 post-event update, an organizer reported that the conference badge contained 20 puzzles and that its full source code had been released.
Iowa CH585 RISC-V NFC badge with village-collection CTF
An official BSides Des Moines 2026 badge documented by the iot-pwn bsidesdsm26 repository as a WCH CH585 RISC-V board with an integrated ISO 14443A NFC reader, four SK6812 RGBW LEDs, a main control button, audio, and a three-layer CTF with two static flags, an eight-tag village-collection challenge, and a hash-based unlock, for the June 13, 2026 edition in Ankeny, Iowa.
Irish STM32 touch-and-sound electronic conference badge
A source-backed BSides Dublin 2026 Harp Badge: the organizer-owned public repository preserves firmware, a hardware reference, production files, and a post-event update path for the May 23 Trinity College conference.
Optional organizer e-badge ticket add-on paired with a distinct 2026 source archive
BSides Fort Wayne's organizer ticket page offered a $30 optional e-badge add-on for the June 6, 2026 conference. The public BSidesFW2026Badge repository has distinct June 2026 activity, including a dedicated STLs/2026 enclosure set and default badge data changed to 2026, together with MicroPython source and inherited V4 technical documentation. The evidence links a real optional e-badge offer to a 2026 source archive without claiming a confirmed sale, physical receipt, firmware deployment, or exact final hardware configuration.
Planned Portuguese Security BSides electronic badge; technical details pending
BSides Lisbon's current official 2026 About page says the October 29-30 conference will have talks, networking, an electronic badge, and a CTF. The official home and location page place the planned event at Auditório Prof. Simões dos Santos in Lisbon, and the current team page lists Pedro Umbelino under Badge. This is a source-backed planned electronic-badge programme, not evidence of a completed board, technical implementation, or badge-linked CTF.
Portuguese BSides electronic badge experience
A conservative post-event record for BSides Porto 2026's advertised electronic badge experience, anchored to the official site, agenda, ticketing page, and organizer completion recap rather than component-level badge documentation.
RP2040 CAN/CAN FD vehicle-network CTF badge, with post-event fulfillment unverified
Car Hacking Village publicly announced its DEF CON 34 CTF badge. Official Village posts identify an RP2040, DB9 CAN 2.0/CAN FD support, interactive power management, and a 12 V 1.5 A power supply; the public `chv_badgetools` repository identifies itself as host-side CAN utilities for the DEF CON 34 badge. The scheduled August 6-9 Las Vegas event window has elapsed, but reviewed post-date sources still do not prove final badge manufacture, allocation, handoff, CTF operation, or a released final firmware.
Planned interactive hackable-badge competition for London
CyberThreat's official 2026 site and SANS registration page advertise an interactive hackable-badge challenge and a Hackable Badge Competition for the November London event. They establish a planned 2026 badge activity, not a released physical or electronic badge specification, attendee-wide issue, or completed handoff.
HTX village badge with illuminated public-safety icons
HTX's official DEF CON Singapore coverage documents Public Safety Village badges, including a badge image described as featuring illuminated icons of emergency vehicles, alongside the first DEF CON Public Safety Village.
CSIT C517 finalist BLE mesh challenge hardware
A source-backed TISC@DEF CON SG finals challenge artifact: CSIT's official C517 page documents the on-site TISC finals, and a finalist writeup says each of the top-50 finalists received an ESP32 hardware trinket running a customized BLE mesh chat protocol to reverse engineer.
Limited ticket-holder CH573F badge with a public hardware archive
DOJOConf Panamá's official page advertises a limited, separately purchased electronic badge available only to ticket holders, with an integrated OLED, four physical buttons, and a rechargeable USB-C battery. An organizer-controlled update says the 2026 badge will be useful in the CTF, and an Electronic Cats post names that organization as the edition's designer and maker. Electronic Cats' public `badge-dojocon-2026` repository separately identifies itself as the official Badge DojoCon Panamá 2026 archive and has a pre-event v1.0 release. Its commit-pinned documentation records a CH573F RISC-V/BLE design with an OLED, directional buttons, a WS2812B LED, USB-C, and a battery connection. These sources establish a real event artifact and public design trail, not completed delivery or a source-to-recipient configuration mapping.
ESP32-S3 MicroPython game badge
A Finnish Disobey badge built around ESP32-S3, a 1.9-inch TFT display, SK6812MINI RGB LEDs, joystick/buttons, MicroPython game firmware, OTA setup, web flashing, badge competitions, and a public hardware/firmware repository.
Maker-documented RP2040 community eBadge with firmware, art, and SAO sources
RestiaAshdoll8's public DEFCON-SG-2026-Div0-Tingkat-eBadge repository says it contains source code and relevant files used in a physical Div0 Tingkak eBadge. It preserves a UF2, RP2040/Pico-focused source, artwork, and SAO project files. Its sources conflict on event identity: the repository title names DEF CON Singapore while its firmware menu banner says SINCON 2026 BADGE. This record keeps the DEF CON Singapore association maker-declared rather than resolving that conflict into official event status.
Source-backed CH32V003 student-bootcamp electronic badge
Hackin7's public project page identifies a deployed electronic PCB Hackbadge created for Greycademy 2026. NUS Greyhats' official announcement says program participants could take home electronic badges, while the primary maker record identifies a CH32V003 coin-cell design and reports an event-day power-reliability repair across more than 200 programmed units. The public trail does not define every recipient, final firmware image, or all-unit configuration.
Pre-event independent two-object ESP32-S3 interaction badge project for DEF CON 34
Two contemporaneous project posts authored by the public Reddit account u/zer0patient and signed H4irl1n3 M0gg3r5 describe an independent planned DEF CON 34 Zombie Badge project. The later source explicitly describes two objects using ESP32-S3, IR, NFC, BLE, a buzzer, and a source-described transmission/counter relationship; it also announces a firmware-based, multi-stage CTF and an unreleased backend. It further describes crew-operated live transmission zones, fixed Cure Stations, hidden 3D-printed medkit props, and a separate brain-in-a-jar SAO. The earlier post calls the work the team's first year making badge or badges, says a second variant is part of the experience, and announces intended drop-based distribution. These are source-backed pre-event maker statements about a real planned artifact system, not proof of final manufactured variants, component selection, wireless behavior, game implementation, inventory, drops, event authorization, DEF CON organizer affiliation, conference admission, or reusable-image rights.
nRF52840/SX1262 electronic conference badge with a public post-event GPL firmware archive
Hackers Teaching Hackers' official materials establish the June 3-5, 2026 Columbus-area practitioner conference with villages and a CTF. Zack Nagaich's public Eagle 5 repository labels itself the 2026 HTH conference-badge firmware and documents an nRF52840 plus SX1262 electronic badge with LEDs, USB roles, RNode/Reticulum-oriented firmware, on-badge CLI, and CTF source context. An attendee account independently says their light-up badge was part of the conference CTF, while the organizer has not directly published this 2026 repository or a distribution record.
Founder-announced 3D-printed/NFC badge for Pirate Pieces of Eight
NaClCON's official registration included a NaClCON Badge and access to the Pirate Pieces of Eight CTF, while the official schedule listed a CTF and Badge Intro. A public pre-event announcement by founder Luke McOmie (Pyr0) describes a 3D-printed/NFC conference badge for the Pieces of Eight CTF and Pirate Scavenger Hunt. The event later occurred, but no reviewed post-event source directly establishes final badge fabrication, attendee handoff, or the announced NFC implementation, so this is retained as a source-backed pre-event artifact announcement rather than a shipped-hardware claim.
Sold-out independent Puzzled Hackers LED meetup badge for DEF CON 34
Puzzled Hackers' own CTF checkout page calls this a limited-edition LED badge for DEF CON 34 and, in the August 4, 2026 source pass, lists $20 including tax, in-person pickup at the Linq 3535 / Circle Bar on Wednesday August 5 and Thursday August 6 from 7–10 PM PT, no shipping, and exhausted online allocations. A contemporaneous Puzzled Hackers Team announcement says the top 50 CTF participants received free-badge redemption on their accounts, remaining sales were capped to break even, further badges would move to random giveaways after the cap, and collection requires a meetup or arranged DEF CON handoff using an offline QR claim code. It also explicitly says the meetup is free and that an actual DEF CON badge is not required for the first Wednesday gathering. The sources support a real, independently distributed LED badge and a community CTF/meetup context, but not its physical construction, components, firmware, final quantity, free-claim count beyond the stated top 50, delivery, event authorization, DEF CON organizer affiliation, admission, or reusable-image rights.
Post-event STM32U073 badge with MIT firmware, AI control, and CTF surface
A post-event official RHC firmware release documents the AI-Connected DEF CON 34 badge as an STM32U073 device with a 1.54-inch 200×200 e-paper display, two WS2812 eyes, arm LED, buzzer, vibration motor, NEC infrared, CH340 USB serial, four buttons, on-badge CTF challenges, and AI Interactive Mode. The MIT-licensed source and binary were published August 18-20 after the scheduled August 6-9 Las Vegas programme. This establishes a released badge platform, not a recipient count, individual pickup, or a complete production ledger.
Pre-event unique hardware badge challenge
A current pre-event record for the October 2-4, 2026 RomHack Camp at Flaminio Village, whose public event site and participant FAQ advertise a unique hardware badge and collectible challenge rather than final shipped hardware details.
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.
limited first-180 ticket PCB badge
SECCON 2026 is represented by an official pre-event ticket source that says eligible passes include a PCB badge with CTFs and features, limited to the first 180 registrants.
Maker-documented ATtiny85 Hardware Village CTF badge soldered in Goa
The official Seasides and HW101 pages establish a Goa Hardware Hacking Village where people soldered take-home badges and worked on a hidden hardware/firmware challenge. A public project-owner archive calls a concrete board the Seasides 2026 Roulette Badge, says that more than 300 participants assembled it live, and publishes its C firmware, schematic, and Gerbers. The archive makes this a source-backed maker-documented instance of the village badge, but the official event pages do not independently name the Roulette design or confirm that every village or conference badge used that exact final configuration.
Publicly announced 100-unit ESP32-S3 badge offering planned for DEF CON 34
A contemporaneous public r/Defcon post calls this a Sneakreaper limited-edition DEF CON badge and says only 100 would be available at a Sneakreaper Industries booth; the post author later replies with Hall W4 and $150. The same post names an ESP32-S3-MINI-1-N8, Wi-Fi, Bluetooth, 13.56 MHz NFC, and programmable LEDs. Crucially, it says that most listed capabilities will not be ready out of the box: only LED colour/brightness changes, a hidden software CTF or scavenger hunt, and NFC read/write are marked as available on DEF CON day 1. The official DEF CON forum fixes the related conference at the Las Vegas Convention Center on August 6-9, 2026. These sources support a real independently announced pre-event hardware offering with a bounded day-one feature claim, not verified seller identity or Sneakreaper Industries relationship, official booth authorization, completed manufacture, final inventory, sale, handoff, electrical design, firmware release, future functionality, lawful-use assurance, DEF CON organizer affiliation, conference admission, or reusable-image rights.
Pre-event independent BLE number-station puzzle badge for DEF CON 34
Station 562 is a source-conservative independent DEF CON 34 badge record from its public maker announcement. The project owner describes a proximity-controlled badge with a BLE number-station puzzle, red-versus-blue proximity game, autonomous social/dance mode, expressive BLE MIDI instrument, tamper-evident mode, Setup menu, and optional hardware CTF. In follow-up comments, the maker reports about 55 units made so far, signed firmware with a distinct key pair per badge, a constrained giveaway/sale plan, and RGB blank boards that omit the OLED, LiPo, and ESP32 module. No public repository, schematic, firmware release, final availability ledger, or reusable-image permission was recovered.
French ESP32-C6 B.A.D.G.E. with OLED, SAO, and BLE color propagation
The official THcon 2026 B.A.D.G.E. page documents an ESP32-C6 electronic badge with the Badge3000 WiFi access point, an I2C OLED at address 0x3C, and BLE padlock and one-time-password challenges for the May 5-6 tenth edition in Toulouse. A May 13 first-hand attendee teardown identifies the distributed board as an ESP32-C6-WROOM-1 build with an SSD1306 OLED, WS2812 RGB LED, ATC24C04 EEPROM, SAO connector, single-cell battery/TP4056 charging path, and USB-C CH340C serial bridge; it also documents the delivered firmware's BLE color-command propagation behavior.
Public player-guide electronic challenge badge; allocation unverified
BigDawgDave's public GitHub repository describes itself as the public repository for a DEF CON 34 RM-Cyber challenge badge called The Shattered Shard. Its Player Guide tells participants to use an assigned badge with a charged battery, a local Wi-Fi/browser interaction, a data-capable USB cable, a serial terminal, and one labelled-jumper task. It is enough evidence to preserve a separately named, independently documented pre-event electronic challenge badge, but it does not prove the RM-Cyber relationship, organizer authorization, hardware provenance, sale or giveaway, run size, allocation, physical handoff, completed on-site use, admission function, or a rights-cleared image.
CH573F BLE virtual-pet and CTF electronic badge
A source-backed Peruvian Unknown Security Conference 2026 electronic-badge record that joins the official pass's lanyard-and-badge inclusion with Electronic Cats' self-described official Pwn Llama badge repository. Its public history shows hardware work before the June 4-6 Lima event and a July documentation update.
Maker-documented ESP CTF challenge badge
A public maker archive explicitly titled Women's International Cybersecurity Challenge Badge 2026 links itself to WICC and documents a hackable serial-CLI CTF badge with ESP8266 and ESP32 target trees, challenge activities, a two-part protective case, and a repository photo of a physical cased device. WICC's official site and Cyber Ireland's post-event recap confirm the completed July 9-10 Dublin competition, but neither organizer source names this exact project. TOG separately reports building 15 ESP8266 hardware flags for the same CTF without identifying them as this archive, so this is a maker-documented event-linked electronic badge—not an organizer-issued credential, general attendee badge, or claim of equivalence to the flags.
Pre-event RP2350 CTF-adventure BadgeLife badge for DEF CON 34
BigTaro's own Wordweaving Badge project page and live Uberflux listing describe an independent DEF CON 34 top-down adventure / CTF badge. The current maker payload shows a $120 100-unit presale with 41 sold, DC34 pickup, and post-con shipping; it also says the badge would be $140 at the maker-described Hacker Warehouse booth during the conference. The maker describes an RP2350 with 4 MB flash, 16 RGB addressable LEDs, a 128×128 grayscale display, rechargeable LiPo via USB-C, and a fully addressable SAO port. It publishes game, CTF, multiplayer, word-building, and optional-component claims, but says hardware documentation and a stub firmware will only be provided after the conference. The project page says 30-plus CTF puzzles while the live listing says 35-plus, so the record preserves a broad maker-described challenge surface rather than resolving the discrepancy. This is a source-backed pre-event independent badge, not proof of final hardware/firmware, shipment or pickup, game availability, CTF completion, venue authorization, DEF CON affiliation, conference admission, or reusable-image rights.
