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.

SourceDEF CON's official badge-help page credits Wietsman with electrical wellness checks and placement/initial routing of the badge carrier PCB.
SourceDEF CON's homepage, official ticket page, and media server establish the DEF CON 34 event context, Human badge preregistration guarantee, and public DC34 SAO specification trail.
SourceDEF CON's official badge-help page identifies AQS as general contractor for material handling, SMT, final assembly, and testing. It does not publish batch quantities, unit-level test results, or a delivery ledger.
SourceDEF CON's official help page identifies bunnie as badge-team lead, Baochip-1x/core-module/plastics designer, firmware author, and manufacturing/operations coordinator; the July 31 official reveal independently names Bunnie Huang as badge creator. This records published roles, not a claim of sole authorship of every component.
SourceThe public DC34 Any Angle Pirate Wheel README identifies Make It Hackin as the designer/project publisher for the optional capture-ring design. This is a source role only, not an official DEF CON role, an accessory-approval claim, or an image-reuse grant.
SourceDEF CON 34 is now a source-backed completed entry in the main badge lineage, with an unusually concrete post-event transition from conference credential to security-token hardware. The update preserves the useful public source and firmware trail while keeping unit-by-unit production parity, final allocation, vulnerability remediation, and image rights bounded.
DEF CON's official help page says the badge uses the newly launched Baochip-1x system-on-chip and describes a detachable clear-plastic core module: after the conference, the holder can remove that core from the badge carrier and seal the carrier holes with included parts. Bunnie's public `dc34-core-hw` repository publishes the core module's KiCad files under CERN-OHL-W-2.0. The DC34 SAO specification documents 3.0 V VDD, a tested 100 mA total supply across both SAOs, two AA batteries, USB-C continuous-power behavior, GPIO4 wake, I2C devices at 0x3C and 0x19, and mirrored unkeyed female 6-pin headers. Those sources do not provide a complete per-unit BOM, carrier-board source release, battery specification, electrical-safety or compliance result, manufacturing test record, or exact physical configuration for every issued badge.
DEF CON's official help page links public `dc34-vault`, `dc34-console`, `dc34-api`, Xous OS, and core-hardware sources. `dc34-vault` identifies the conference UI as an encrypted-QR light-pattern exchange and describes the detached core's security-token mode, including FIDO2, password, and TOTP functions. The public Apache-2.0 `dc34-image` and `dc34-bio` tools document USB-serial image and BIO loading. The help page also links a current firmware-update archive and says patches were being issued after the conference. These sources establish a released software and update surface, not that every issued unit runs one later source revision, that every function is secure or supported indefinitely, or that loading custom code preserves conference secrets.
DEF CON's August 10 news post says DEF CON 34 wrapped, and its August 9 badge-sale notice confirms spare badges were offered at registration while supplies lasted. The conference used the Agency theme. The official help page explains that badges could exchange encrypted light patterns by scanning QR codes during the conference, then be repurposed after the conference as a hardware token. It names Bunnie as badge-team lead, identifies Cheeso collaborators for badge design and artwork, and credits production vendors. These published roles and feature descriptions do not establish a full recipient list, complete production count, challenge completion, every shipped firmware state, or permission to reuse official badge photos.

Call Center Village's official shop describes a $5 pickup-only Solder-It-Yourself Telephone Booth SAO Kit for the DEF CON 34 badge. Its current public Badgelife roster row separately lists a $5 kit and $10 pre-soldered option. These source statements establish offered configurations and planned event context, not final inventory, payment, assembly, pickup, shipment, delivery, refund, replacement, or support outcome.

SourceDEF CON's July 31 official reveal names Bunnie Huang as the badge creator and says the badge features his open-source, fully inspectable Baochip; it does not announce final firmware, board files, or distribution details.
SourceThe SAO spec states that the badge is powered by two AA batteries and that USB-C power-bank operation keeps the badge continuously on.
SourceDEF CON's official badge-alert post says DEF CON 34 is an electronic badge year, that the badge comes from a hardware hacking legend, and that the SAO spec sheet is early support for add-on projects.
SourceThe public `bunnie/dc34-image` README identifies a Python utility for uploading a black-and-white 128×128 image to a DC34 badge over USB serial. It documents a customization path, not physical display technology, a selected shipped image, a final embedded firmware build, or event-unit parity.
SourceThe public `bunnie/dc34-bio` README identifies a Python utility for loading a BIO program to a DC34 badge over USB serial, with documented SAO-I/O selection and clock configuration. It documents a user-side tooling path, not complete embedded firmware, final connector mapping, safe settings, a supported end-user workflow, or event-unit parity.
SourceCall Center Village's public source calls this a phone-booth-shaped, power-only SAO v2: one 1206 LED and one 330 ohm current-limiting resistor are wired in series from VCC to GND, with no microcontroller or I2C and the SDA, SCL, GPIO1, and GPIO2 pins left unconnected. The repository includes KiCad project, schematic, PCB, connector symbol, BOM, placement, netlist, Gerber packages, and a CC BY-SA 4.0 license. It does not prove final kit or pre-soldered population, per-unit quality, current draw under an actual host, final production revision, DC34 electrical test result, user assembly outcome, or general host safety.
SourceDEF CON's official ticket page says preregistration guarantees a DEF CON 34 Human badge when the ticket is redeemed onsite in Las Vegas.
SourceThe upstream Baochip-1x repository publishes open-source chip-hardware elements, taped-out RTL, VexRiscv configuration, simulation/FPGA material, and a CERN-OHL-W-2.0 license. It documents the announced chip context rather than a complete DC34 badge board or firmware image.
SourceMake It Hackin publishes one STL intended to be printed twice as a two-piece capture ring that lets a wearer suspend the official DC34 badge at different rotations, using user-supplied M3 hardware or zip ties and a dual-clip lanyard. The maker says its geometry was photogrammetrically derived and is not an official DEF CON drawing; this is a design file, not a shipped, tested, or DEF CON-approved accessory.
SourceUberflux maker `bud-lightbeer` lists a $4 180-degree SAO adapter for the DEF CON 34 ports, which the maker describes as upside-down relative to the intended SAO 2.0 orientation. The listing says the adapter does not change the badge's 3.0 V supply and warns complex SAOs may not tolerate it; its current marketplace snapshot shows 593 sold, seven remaining, and Friday/Saturday Badge Life Booth pickup. This is a third-party compatibility product, not an official finding of a port defect or a universal compatibility guarantee.
SourceThe listing says a standard USB wall brick or portable battery pack can power the Power Back, that an SAO totem can run multiple SAOs, and that it runs three #NOICE or Not Just a Crosswalk SAOs where a regular CR2032 does not have enough power. It does not publish a pinout, USB-C or USB-PD behavior, cable requirements, regulator/protection design, output-current limit, voltage tolerance, heat test, electrical-safety certification, tested SAO matrix, or universal compatibility result.
Sourcecaelyb's Uberflux listing describes a USB-C-to-SAO Power Back with maker-described 5 V-to-3.3 V conversion that lets SAOs run without a host badge, including desk or shelf display. As reviewed on 2026-08-04 it showed $7, 59 sold, 81 remaining, DC34 BadgeLife Village/LineCon/Queercon pickup labels, and post-DC34 CONUS shipping. It is a third-party standalone SAO companion associated by the maker with DEF CON 34, not an official conference item or a main-badge-mounted add-on.
SourceOperational history
The catalogue can document the simple published design and its source files without calling the generic SAO v2 description a verified DC34 electrical match, a universal host compatibility result, a safe assembly procedure, or a completed unit/fulfillment record.
The catalogue links the public archive and records the documented state transition without recommending installation, claiming that a later source tree exactly matches every badge, or presenting the token and QR features as independently validated or permanently supported.
The entry stays image-free rather than copying official news/support graphics, ticket media, media-server diagrams, social-media or press previews, repository screenshots, or generated badge art.
The catalogue can treat the official electronic Human badge as completed without implying that every registration produced the same physical unit, that every holder received or retained one, or that a public source proves a complete manufacturing and fulfillment record.
The catalogue records an optional third-party mechanical design without treating it as an official accessory, a fit result, a port-orientation diagnosis, an electrical-safety conclusion, or a finished product. The source does not establish print material, assembly quality, mechanical loads, badge/port clearance, pinout/orientation outcome, safety validation, production, sale, delivery, support, or image reuse rights.
The catalogue records a source-backed third-party standalone SAO power/display companion without treating its maker-described 3.3 V conversion or multiple-SAO example as official main-badge support, a universal-compatibility claim, or a safety endorsement.
