NaClCON 2026 3D-Printed NFC Conference Badge

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.

NilbinSec DC34 Main Badge Fuzzer SAO

Independent ATtiny1614 DEF CON 34 badge-challenge fuzzer SAO

NilbinSec's public DC34 Main Badge Fuzzer SAO repository documents a standalone SAO designed to exercise interfaces on the official DEF CON 34 Human badge using information published before the conference. Its README describes three initial modes: GPIO1/GPIO2 stimulation on the left SAO port, an open-drain CPU wake assertion on GPIO4 of the right port, and an I²C-address listening sweep. The repository provides a KiCad schematic, BOM CSV, PCB archive, C firmware, and compiled hex/ELF files. The README explicitly warns that Mode 1 may harm the main badge and says a convention reflash might follow. This is source-backed pre-event independent challenge hardware, not proof of a finished run, sale, giveaway, pickup, compatibility with a final main-badge revision, authorization to probe another badge, official DEF CON issuance or admission, a reusable-image grant, or an explicit software/hardware licence.

NilbinSec PAC-MAN Ghost SAO (DEF CON 34)

Independent planned free PAC-MAN Ghost SAO giveaway for DEF CON 34

NilbinSec's public DEF CON 34 Badgelife response names a new PAC MAN Ghost SAO, calls it free, says 1,000 will be given away, and promises social-media and village drops plus a Day-1 GitHub post. A first-party NilbinSec Bluesky reply in its Spectre Sniffer launch thread separately says a purchase includes a PAC-MAN Ghost SAO and helps fund more than 1,500 free SAOs for Vegas. The live Spectre Sniffer listing says it includes one Pac-Man Ghost SAO in one of four colors. Those sources establish a real planned companion SAO and current event association, but they do not establish whether the 1,000 giveaway, purchase-included, and four-color statements describe the same physical revision/variant; an electronic design, connector specification, final artwork, actual drop, GitHub release, official DEF CON issuance/admission, reusable-image permission, or third-party intellectual-property authorization.

NilbinSec Power Glove Re-release SAO (DEF CON 34)

Independent planned 500-unit Power Glove SAO re-release for DEF CON 34

NilbinSec's public DEF CON 34 Badgelife response identifies a Power Glove Re-release SAO as a free giveaway: 500 units, with drop announcements on social media and at the Badgelife Village, and a stated plan to post it to NilbinSec GitHub on DEF CON Day 1. The maker's existing DC32 Power Glove SAO repository preserves a historical fabrication/assembly trail—Gerbers plus a bill of materials with two 470-ohm resistors, three flashing RGB LEDs, one cloudy red LED, and a 2×3 shrouded SAO header. It does not publish a 2026-specific repository, firmware, change log, or production record. This is a source-backed planned independent re-release, not proof that the 500 units were made, dropped, received, electrically identical to the DC32 design, officially issued by DEF CON, usable for admission, licensed for reuse, or represented by a rights-cleared image.

NorthSec 2026 Badge

Official ESP32-S3 NFC e-paper badge with post-event Apache-2.0 source release

NorthSec 2026's official registration page lists a new social electronic badge as an included item for conference, CTF, combo, and training ticket holders while supplies lasted. The official competition page's retained 2026 Solarpunk section says the hackable electronic badge was fully integrated into the CTF, with badge challenges worth points and on-site badge-firmware tampering among the physical tracks. Official villages pages document badge pickup through attendees' nSec order QR codes, soldering-village activity where attendees could enhance their badge with blinking electronic parts, and a badge museum. On August 3, after the May event, NorthSec published the separate Apache-2.0 `nsec/badge-2026` repository. Its commit-pinned hardware and source tree documents an ESP32-S3 badge design with an ST25R3916 NFC front end, six buttons, eighteen WS2812/NeoPixel LEDs, a 200×200 GDEH0154D67 / SSD1681 e-paper path, KiCad design files, production BOM/CPL/Gerbers, PlatformIO firmware, conference/CTF partitions, CTF assets, and dock/SAO directories.

Not Just a Crosswalk SAO (DEF CON 34)

Planned open-hardware CH32V003 light-up Simple Add-On for DEF CON 34

The maker-owned public `keeloi79/not-a-crosswalk-sao` repository explicitly calls Not Just a Crosswalk a Simple Add-On (SAO) project for DEF CON 34. Its README documents a CH32V003 F4P6 RISC-V controller, eighteen side-emitting addressable LEDs, persistent palette/effect settings, two controls, 3.3 V host-badge power stepped to 5 V or a USB-C 5 V input path, and claimed SAO V1.69bis/V2.0 compatibility. The source tree includes documentation, schematics, firmware, build instructions, and a three-part license declaration: CERN-OHL-S v2 hardware, GPLv3 firmware, and CC BY-SA 4.0 documentation/creative works. This is a source-backed planned independent DEF CON 34 add-on, not evidence of a final manufactured run, price, sales channel, quantity, pickup, recipient, host-badge test matrix, electrical-safety validation, official DEF CON affiliation, admission right, or rights-cleared badge image.

OWASP SAO (DEF CON 34)

Source-published 15-pixel touch SAO firmware project; physical artifact and handoff unverified

Punk Security's public repository calls its Arduino sketch "the firmware for the OWASP DefCon 34 SAO." Its final public source snapshot provides an actual `main.ino` rather than an event-labelled name alone: it defines 15 addressable RGB pixel positions, three PTC capacitive-touch nodes, and a README that says the SAO header exposes UPDI for reprogramming. This clears the catalogue threshold for a named, source-published pre-event electronic add-on project. It does not establish a final PCB, microcontroller, power path, exact SAO specification, fabricated unit, approved OWASP or DEF CON relationship, price, allocation, pickup, delivered handoff, credential function, or reusable image rights.

Open ESP32-S3 Chicago builder-festival hardware badge

Onion DAO's official 2026 Chicago festival page says every accepted attendee gets a hardware badge at registration, with most components already on the board and a final soldering step. The same official site links to OnionDAO's public oniondao-badge repository, which documents a hacker-conference-style ESP32-S3 design, optional RF/audio modules, a display socket, secure element, expansion ports, and source trees for hardware and software. The public record supports a real organizer-published artifact and design, while exact recipient allocation, completed assembly, and final attendee population remain unverified.

Open Sauce 2026's SauceBot badge is documented by Caleb Marting's post-event public archive as an Arduino MKR Zero-compatible electronic badge with native KiCad sources, firmware, a microphone, button, red LEDs, battery holder, and optional Simple Add-On headers. The archive says at least two attendees hacked badges Saturday night and brought four new games on Sunday; an independent attendee firmware archive also describes receiving an eyebrow module and replacing the original Bop It-style firmware. Together the sources establish a real festival artifact and hands-on hacking trail, not a universal attendee allocation or organizer-owned source release.

Original Series Tricorder Badge (DEF CON 34)

Independent planned sensor-described Original Series Tricorder badge sale at DEF CON 34

MakeItHackin's public DEF CON 34 Badgelife response lists a new Original Series Tricorder badge, says it will be available on-site at DEF CON through Hacker Warehouse for approximately $125, and describes it as celebrating 60 years of Star Trek with various sensors. The source field for the current badge is still marked TBD. The same maker's public Tricorder SAO repository, tutorial, and live $30 Tindie listing document a differently named 2025 Tricorder SAO with separate badge-powered and rechargeable-battery forms. Those historical sources establish a related public maker lineage, but they do not map their electronics, LEDs, battery/USB-C details, form factor, price, or distribution to the current $125 Original Series Tricorder badge. This is a source-backed planned independent sensor-described event artifact, not proof of a completed sale, disclosed sensor suite, electronic design, final hardware/firmware, historical-SAO parity, official DEF CON issuance or admission, reusable-image permission, or Star Trek rights-holder authorization.

Ouroboros Badge (DEF CON 34)

Independent CH32V003 bare-metal UART crypto-puzzle badge offered toward DEF CON 34

K Badges' maker-controlled Tindie listing identifies Ouroboros as a $29.99 bare-metal RISC-V-assembly electronic badge on a CH32V003, with a custom UART cryptographic puzzle, a 12-LED Charlieplexed matrix, a circular single-layer PCB with exposed traces, and a hand-soldered two-AA configuration. Its August 4, 2026 storefront snapshot is out of stock; the seller says a new order is coming and hopes to bring some to DEF CON, rather than confirming units, arrival, pickup, or delivery. In a first-person r/Defcon announcement, the maker says they created the project and links the Tindie page and a GitHub technical explainer, while separately offering to arrange a DEF CON pickup by email for Tindie buyers. The product also makes 115200-baud puzzle, cryptographic-framework, low-power, and performance statements, but neither the product nor the maker-linked generic AVR framework establishes a released matching CH32V003 firmware or hardware package. This is a source-backed independent pre-event maker offering, not an official DEF CON badge, registration credential, confirmed fulfillment, verified cryptographic implementation, hardware-safety record, or reusable-image source.

Portal Badge (DEF CON 34)

Pre-event CH32V303 Portal puzzle badge from a public DC34 source tree

BigFuckingBadge's live DEF CON 34 page calls this year's Portal Badge a 14×14-inch Companion-Cube-shaped, touch-activated badge, marks presale open with limited quantities, and advertises $120 before DEF CON 34 or $150 through hackerwarehouse during the con. A public GitLab hierarchy at `hexum-public-share/bfb/dc34/public/badge/portal-badge` contains separate software, hardware, and sound projects for the same Portal-themed badge. The source names a `ch32fun-portal-badge` firmware project and a `ch32v303-48lqfp-portal-badge` board project; its current software configuration targets a CH32V303CBT6 with PlatformIO and ch32v003fun. The committed firmware defines 85 LED pixels, fourteen active-low inputs, SD-card-backed audio with DAC playback, flash-persisted unlock state, a serial Portal Gun SAO/badge-to-badge protocol, and diode-solder-on detection. Its design document describes standby, Nyan, and a four-level Portal puzzle game built around spheres, portals, fire, and unlockable features. Public commits show software “final code checks” and hardware acrylic SVG work on August 2, 2026. This is a source-backed pre-event independent record, not proof of a completed sale, physical run, event allocation, pickup, official DEF CON credential, final binary, safety validation, third-party-IP permission, or reusable-image rights.

Portal Gun SAO (DEF CON 34)

Independent PFC161 touch-and-four-LED companion SAO announced for DEF CON 34

BigFuckingBadge's public DEF CON 34 Badgelife response lists a new $20 PORTAL gun SAO and says touching its end changes animated colors and interacts with the PORTAL Badge. The maker's live DEF CON 34 page independently describes a $20 Portal-gun companion with blue, orange/red, and off modes plus interaction with that year's Portal Badge. Hexum064's public `portal-gun-sao-dc33-code` source targets PFC161, defines a four-pixel LED buffer, blue/orange color states, a capacitive-touch threshold, and a touch-triggered state update; the public hardware tree holds KiCad, BOM/position, Gerber, and acrylic files. The source repositories retain `dc33` in their names, so they are an implementation/reuse trail rather than proof of a newly designed or unchanged 2026 production revision. Together the sources establish a real planned independent electronic SAO associated with DEF CON 34—not official DEF CON issuance, admission, confirmed fulfillment, a finalized host-compatibility claim, final hardware/firmware parity, third-party-IP permission, a source-license grant, or a rights-cleared image.

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.

A September 26, 2026 recheck found the official homepage carrying a SECCON 2026 photo gallery with September 2026 image uploads while the former ticket page no longer resolves, so the event holding is now officially evidenced while badge handoff stays unverified.

Seasides 2026 Roulette Badge

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.

SecretCon 2026 Digital / Circuit Badge

Official interactive PCB ticket-tier badge; post-event delivery remains unverified

An official SecretCon 2026 Digital / Circuit Badge ticket-tier artifact advertised as an interactive circuit-board PCB badge for the June 4-5 St. Paul, Minnesota conference. The registration listing says the tier included a printed physical program and admission to talks, hands-on hubs, exhibitors, contests, and the official party; it separately describes a higher Extreme Badge tier with collectible electronic and upgraded-PCB wording, without establishing whether the physical boards were different.

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.

Sneakreaper Limited-Edition Badge (DEF CON 34)

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.
