BadgeLife Village Badge (DEF CON 34)
Published pre-event RP2354 BadgeLife village badge; allocation and handoff unverified
Badge.Life's public archive documents Badgey Bodgerton as the Badgelife Village Badge for DC34 / 2026. Its published guide names an RP2354 microcontroller with integrated flash, eight addressable RGB NeoPixel LEDs, three user buttons, one user-installed 3 mm challenge LED and polarized buzzer, USB-C power, USB CDC serial CLI, UF2 firmware flashing, a single-cell 18650 battery with charging and protection circuitry, two Simple Add-On v2 headers, and an infrared receiver. It also documents a supplied bodge-wire challenge and supplied LED/resistor/buzzer challenge parts. This establishes a distinct, technically documented pre-event BadgeLife village electronic badge, not proof that DEF CON designed, issued, or will distribute it; that it is a Human admission credential; that every participant receives one; that a final badge run, pickup, or delivery occurred; or that any displayed image is cleared for reuse.
CactusCon 14 Badge
Badge Pirates ESP32-S3 hardware archive
The CactusCon 14 badge is preserved through Badge Pirates' public CC14 repository, which publishes KiCad design files, schematic PDF, interactive BOM, Gerbers, STEP exports, 3D-printable enclosure parts, and art assets for the 2026 CactusCon conference badge.
Cult of Cthulhu Indie DEF CON 34 Badge
Pre-event ESP32 ritual-game BadgeLife badge
Pfarrside Creations' badge-only listing describes the Cult of Cthulhu Indie DEF CON 34 Badge as an ESP32-powered interactive BadgeLife project that turns a DEF CON setting into a Cthulhu summoning ritual. The seller's page names ESP32, USB-C, rechargeable Li-Po power, ten LEDs, a screen, one-button input, badge types, a 13-chapter Ritual, six side-quest challenges, badge-to-badge Séance behavior, and unlockable games. It also states a second-week-of-July US-only shipping schedule with no DEF CON pickup. This is a maker-published independent badge listing, not verified final delivery or an official DEF CON admission credential.
DEF CON 34 Badge
Completed electronic Human badge with Baochip, QR interaction, and post-event token conversion
DEF CON's official news confirms DEF CON 34 wrapped on August 10, 2026. Its official badge-help page now documents the issued electronic Human badge's post-conference conversion to a hardware security token, current firmware-update path, public source-code links, and the in-conference encrypted-QR light-pattern exchange. The official July 31 reveal names Bunnie Huang as creator and Baochip as the inspectable silicon platform, while the public core-module KiCad archive and `dc34-vault` source provide a specific hardware and software trail. This establishes a completed official badge record without treating later public source as a production ledger or a reusable-image grant.
DEF CON 34 Silent Disco Badge
Maker-published physical silent-disco badge; organizer role and handoff unverified
LastZactionHero's public repository is titled DEF CON Silent Disco Badge and documents a wearable electronic badge that plays local DJ mixes, drives a music-linked light show, and syncs badge-to-badge over infrared. Its August 4 maintainer update says the boards were fabricated, assembled, and playing music, and that every badge's QR silkscreen points to the repository. The public archive contains KiCad design and fabrication material, firmware, and a MIT license, sufficient to record a distinct maker-published physical DEF CON 34-associated artifact. No reviewed DEF CON, venue, silent-disco organizer, sales, or handoff source establishes official issuance, a run size, recipient allocation, or completed event distribution.
DEF CON Singapore 2026 DC-SG-1 Official Badge
ESP32-C6 attendee badge with Laser* Tag and hardware-hacking workflow
The inaugural DEF CON Singapore attendee badge, DC-SG-1, is an official electronic badge issued to ticket holders. Public event workshop and game documentation identifies an ESP32-C6 platform with eight megabytes of flash, an interactive hardware-hacking workflow, USB-C access, and a conference-wide infrared Laser* Tag game.
DOJOConf Panamá 2026 Electronic Badge
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.
Darknet-NG SMAO (DEF CON 34)
Open-source pre-event 125-unit Meshtastic Simple Add-On for DEF CON 34
Darknet-NG's own current badge page identifies the Darknet-NG SMAO as its Level 3 build: a full Meshtastic node in an SAO form factor. The maker's live Uberflux product payload describes a $55 125-unit presale and currently reports 125 sold with zero remaining, no shipping options, and DEF CON 34 contest-booth pickup only; that is a time-specific availability snapshot, not proof of completed manufacture, collection, or delivery. A matching maker-owned, commit-pinned `dcbokonon/darknet-smao` release now publishes the v1.4 KiCad project, fabrication outputs, BOM/placement data, firmware build material, and RF-tuning source, alongside an MIT-licensed official upstream board render. This is a source-backed independent pre-event mesh-radio add-on record, not independent RF/compliance validation, a DEF CON organizer-issued product, conference credential, admission right, or completed fulfillment record.
Friend or Foe Badge (DEF CON 34 Packet Hacking Village)
Completed independent three-radio ESP32-S3 RF-awareness badge
The public Friend or Foe project archive documents a three-board ESP32-S3 badge shown at DEF CON 34 Packet Hacking Village. Its hardware documentation records a 45-badge DEF CON run and the project root describes a wearable, passive RF-awareness platform with an uplink/display controller and dedicated BLE and Wi-Fi scanner boards. Packet Hacking Village's official DEF CON 34 programme independently establishes the completed village setting and the Friend or Foe presentation. These sources establish a completed independent electronic project, not an official DEF CON Human badge, conference-wide handout, admission credential, or recipient ledger.
Gothcon 2026 Blinky Badge
Pre-event ESP32-C3 bat-shaped LED party-fundraiser badge
Gothcon's official badge store describes a custom bat-shaped PCB LED badge for the free Gothcon dance party at DEF CON 34. The $80 fundraiser package names 44 independently controlled RGB LEDs, a 2,000 mAh Li-Po battery, USB-C recharging with overcharge protection, a removable laser-etched acrylic shield, a custom lanyard, and an ESP32-C3 with 4 MB flash. The public `claviger/gothcon-firmware` repository adds MicroPython firmware, KiCad schematic/PCB/Gerber material, GPIO mapping, pattern/palette controls, and ESP-NOW badge-to-badge contagion. The store explicitly says its SAO connectors are mirrored and not functional with a standard SAO. Pre-orders are closed and the store says badges will be sold at DEF CON; this remains a pre-event party-fundraiser record, not proof of final sales, delivery, party outcome, or official DEF CON credential status.
HRV SSTV Badge (DEF CON 34)
Maker-published planned SSTV badge project for HRV/DEF CON 34; physical unit unverified
The public `livitup/hrv-sstv-badge` repository describes itself as building an SSTV #badgelife badge for HRV at DEFCON 34. Its commit-pinned source contains a project README, native KiCad board files, and a status document dated March 22, 2026 that still records design and prototype milestones rather than a shipped unit. Ham Radio Village's own page independently confirms its DEF CON 34 event in Las Vegas on August 6-9, 2026, but does not identify or endorse this project. The sources therefore support a publicly documented planned independent electronic-badge project associated with HRV/DEF CON 34, not an HRV- or DEF CON-issued artifact, ticket benefit, access credential, completed unit, allocation, delivery, or rights-cleared image.
Hacker Pager (DEF CON 34 Revision)
Maker-announced independent Hacker Pager revision for DEF CON 34; handoff outcome unverified
A first-hand Exploitee.rs announcement says the team is bringing a new Hacker Pager revision to DEF CON 34, with planned online availability and BadgeLife Village pickup. Its official project site documents an ESP32-S3, Semtech SX1262 LoRa radio, monochrome LCD, microSD, USB-C, rechargeable LiPo power, buttons, speaker, vibration motor, LEDs, and open design sources; its current update page labels firmware 2.7.26.pager as DEF CON 34. Public electronics and case repositories publish KiCad/BOM and mechanical source material under CERN-OHL-S-2.0. This is sufficient evidence for a distinct, independently sold pre-event BadgeLife artifact associated with DEF CON 34, not evidence of DEF CON issuance, authorization, admission, a completed sale, pickup, delivery, final production configuration, or rights-cleared image.
ICS Village DEF CON 34 Badge
Pre-event RP2350B multi-protocol OT and automotive research badge
The ICS Village DEF CON 34 Badge is an official FREE-WILi page-documented, on-site / Vendor Village, while-supplies-last hardware badge for DEF CON 34. Its technical page specifies an RP2350B-A4 platform with RS485/Modbus RTU, CAN/CAN FD, 10BASE-T1S and 10BASE-T1L, a DB15 connector, OLED, encoder and RGB UI, storage, USB serial, FreeWili Porpoise Purpose Firmware, OneWili API support, and a stated 3.7 V / 1000 mA internal battery. As of this pre-event source pass, it is not a delivered-run or official DEF CON admission credential.
INSPECTRON 34 SAO (DEF CON 34)
Completed independent RP2040 CRT-TV Simple Add-On
INSPECTRON 34 is an independent retro-CRT television-shaped Simple Add-On documented by its maker's post-conference public repository. The project records an RP2040, 16 MB flash, 1.14-inch ST7789V display, CircuitPython, USB-drive GIF loading, a DC34 right-port SAO design, and a completed DEF CON 34 run of about 20 sold boards. The post-conference handoff identifies V5 as the current released firmware. It is not an official DEF CON Human badge or admission credential.
MalO SAO (DEF CON 34)
Pre-event RP2350B interactive Simple Add-On planned for DEF CON 34
ParallelLogic's Uberflux listing, public MalO_SAO source/design repository, and first-hand Hackaday.io project diary document a planned DEF CON 34 Simple Add-On based on the SCP-1471-A MalO setting. The marketplace's August 4, 2026 snapshot lists $50, 43 sold, and 57 remaining. The repository says the units are intended for online sale and DEF CON 34 handout in August 2026, identifies an RP2350B, 16 MB external flash, 1.5-inch 128 by 128 grayscale OLED, standard six-pin SAO header, USB-C, capacitive touch, potentiometer, buzzer, microphone, hall sensor, IMU, ambient-light sensor, IR transmit/receive, NFC/RFID, and LED banks. Its project diary confirms the work is ongoing and documents early prototype testing. The repository declares the work CC BY-SA 3.0. This is a source-backed pre-event independent badge record, not proof that a final revision has shipped, that all promoted functions are complete, that every radio/sensor interaction is safe or private, that a named third-party lore asset grants image rights, that the project is DEF CON-issued, or that it grants admission.
Overglade 2026 Zero-Power NFC E-Ink Badge
Maker-documented RP2040 e-ink/NFC game-jam badge
Kai Pereira's public archive identifies these as Overglade hackathon badges designed for the completed Singapore game jam. The device has an RP2040, passive NFC, an onboard e-ink driver, and an exposed ticket-shaped PCB with public KiCad and MicroPython source trees. Official Hack Club pages establish the event, but not a badge entitlement or all-recipient allocation.
Pwnterrey 2026 Official ESP32-C5 Badge
Official open-hardware headless ESP32-C5 wireless-security badge with public KiCad and C5 firmware sources
Electronic Cats' public badge-pwnterrey-2026 repository describes itself as the official Pwnterrey 2026 badge and publishes a native KiCad hardware project plus a CERN Open Hardware Licence v1.2 file. Pwnterrey's official site places the free cybersecurity conference in Monterrey on May 29, 2026; Bishop Fox separately corroborates the date and Rincón Tostitos By Jardín 85 venue. The source documents a portable headless ESP32-C5 RISC-V badge with USB-C serial context, NFC tag-emulation circuitry, and GPS material. Electronic Cats' companion repository calls itself official Pwnterrey 2026 firmware and preserves an ESP32-C5 Marauder-derived source and build trail. These sources establish a real official event badge and public design and firmware references, but not a production quantity, registration-tier allocation, final assembled configuration, completed recipient handoff, final signed release, safe operational use, or reusable badge-image right.
Shitty Kitty V2 (DEF CON 34)
Pre-event sold-out RP2040 dual-SAO BadgeLife restock
Uberflux lists Shitty Kitty V2 under the `lipo` maker handle and Uberfoo Heavy Industries, with DEF CON 34 as its only listed drop. At this August 3 source pass, the $75 listing is marked OUT with zero remaining and 15 sold, and says new stock is available for DEF CON 34 pickup. Its maker-published description names dual 0.96-inch color IPS screens, an RP2040 platform, two fully connected 1.69bis SAO ports, USB-C, LiPo power/charging components, five user buttons, a boot button, and SkittyOS features. It also announces new firmware with graphics and puzzles, but provides no release link. This is a documented pre-event restock listing, not proof of final pickup, a completed firmware release, a reproduced engineering archive, or an official DEF CON admission credential.
The Beer SAO / BCCC Temperature Badge (DEF CON 34)
Pre-event RP2350 temperature-measuring Simple Add-On for DEF CON 34's BCCC
The live maker listing for The Beer SAO, the public `aerospace-venoms/BCCC_Temperature_SAO` source tree, and BCCC's own DEF CON 34 page document an independent temperature-measuring Simple Add-On associated with the Beer Chilling Contraption Contest. The marketplace's August 4, 2026 payload shows a $45, 150-unit presale with 28 sold and 122 remaining, two BadgeLife Village pickup slots, and no shipping. It describes a roughly 100 mm beer-cup SAO with a waterproof temperature probe, triple seven-segment display, RP2350 with 2 MB flash, USB-C, and a supplied 180-degree adapter for the upside-down DC34 host ports. The source tree identifies an RP2350A, W25Q16 flash, DS18B20 temperature sensor, RGB-independent brightness control, Pico-SDK firmware, KiCad design files, a versioned UF2, and batch programming/soak-test tooling; it says BCCC winners receive copies while stock lasts. This is a source-backed pre-event independent badge record, not proof of final manufacture, pickup, contest results, host compatibility, temperature accuracy, safety, final firmware, DEF CON organizer endorsement, conference admission, or reusable-image rights.
UPDeeDeeI SAO (DEF CON 34)
Sold-out pre-event Lepi Labs UPDI-programmer moth Simple Add-On for DEF CON 34
Lepi Labs' own Uberflux listing identifies UPDeeDeeI as a DEF CON 34-drop moth Simple Add-On. Its August 4, 2026 marketplace state is out of stock, with seven sold, zero remaining, and a $35 listed price. The maker says a CH340E USB-to-serial converter supports UPDI programming of compatible ATtiny devices, names an onboard ATtiny814 with two RGB LED eyes, and describes USB-C plus a flexible FPC tongue used as a functional USB cable. It also claims configurable 3.3 V or 5 V UPDI voltage, SAO or included CR2032 power, and v1.1 pre-event corrections including an FPC power fuse. Lepi Labs' first-hand DC34 announcement corroborates planned Friday and Saturday BadgeLife Village drops. This is a source-backed pre-event independent programming-tool SAO, not proof of final board revision, safe programming configuration, USB/FPC durability, compatible target coverage, delivery, host compatibility, DEF CON organizer affiliation, conference admission, or reusable-image rights.
Wordweaving Badge (DEF CON 34)
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.
