Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
DEF 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.
Badge context
Official media-server PDF documenting DC34 SAO electrical and mechanical constraints, including 3.0 V VDD, two-AA badge power, USB-C power-bank behavior, GPIO wake interrupt, I2C addresses, and mirrored 6-pin SAO header dimensions.
Public Baochip-1x repository with open-source hardware elements, documented taped-out RTL, VexRiscv configuration, simulation/FPGA material, and CERN-OHL-W-2.0 licensing; it does not itself establish final DC34 board or firmware details.
Primary Baochip project site with links to the chip source, hardware reference, operating-system ecosystem, and current public project context.
Public source for the DC34 vault application, including its conference light-exchange and post-event token-mode documentation. The project warns that custom firmware changes the device's provisioned-secret state; it is a source trail, not a guarantee about every unit's software state, long-term support, or security outcome.
Public CERN-OHL-W-2.0 KiCad archive for the DC34 core module. It makes the core hardware design inspectable without proving an all-unit BOM, carrier-board release, production test process, or reusable rights in visible repository media.
Official DEF CON source for August 6-9, 2026 dates, LVCC West Hall location, Agency theme, and preregistration news linking to the official ticket page.
Official $5 pickup-only Solder-It-Yourself Telephone Booth SAO Kit listing for the DEF CON 34 badge. The shop establishes original kit and pickup context; it does not itself provide a component, circuitry, firmware, connector, assembly, or image-reuse archive.
Official event archive page indexing DEF CON 34 schedule, media links, and conference context alongside the main DEF CON index.
DEF CON forum source establishing official DEF CON 34 date framing and supporting event-context references used for badge availability and scheduled logistics.
Forum source confirming that preregistration guarantees Human badge pickup and documenting the August 2026 preregistration timeline and badge entitlement context.
Call Center Village's public Forgejo source project for the phone-booth-shaped power-only SAO v2: KiCad project/schematic/PCB, SAO v2 symbol, BOM, placement, netlist, Gerbers, artwork, and CC BY-SA 4.0 license. It documents a design rather than a final DC34 kit/pre-soldered-unit quality, safety, delivery, or image-reuse record; the source SVG artwork is not used as a badge image here.
Official news archive containing the August 10 statement that DEF CON 34 wrapped, the August 9 spare-badge sale notice, and the July 31 official badge reveal. It establishes event completion and bounded on-site badge-sale context, not a complete distribution ledger.
Official post-conference support page documenting the issued badge's detachable-core security-token conversion, current firmware-update archive, in-conference encrypted-QR light exchange, source-code links, team roles, and vendor credits. It does not establish a recipient list, per-unit production configuration, security validation, or image-reuse permission.
Official event schedule source for DEF CON 34 daily timing and hall-level conference context; it does not provide a badge-technical specification or physical-credential schema.
Official DEF CON update stating that DEF CON 34 is an electronic badge year, that more details are coming, and that the public SAO spec sheet is pre-event support for add-on makers.
Official July 31, 2026 reveal that directly names Bunnie Huang as the creator and identifies the badge's open-source, fully inspectable Baochip.
Official DEF CON 34 vendor directory, useful for add-on ecosystem and booth context; it does not identify official badge manufacture, technical architecture, or finalized distribution mechanics.
Public Apache-2.0 Python source whose README calls it a BIO uploader for a DC34 badge and documents USB-serial program loading plus SAO-I/O and clock configuration. It does not identify a complete final firmware image, final board, safe operating configuration, all connector topology, or a distributed event-unit state.
Public Apache-2.0 Python source whose README calls it an image uploader for a DC34 badge, documents a black-and-white 128×128 image target, and uses the badge's USB serial connection. It does not identify physical display technology, a shipped image, final embedded firmware, or an event-unit distribution result.
Current public DEF CON 34 Badgelife row that lists the Call Center Village Telephone Booth SAO as a $5 kit or $10 pre-soldered item and links its public source project. It supports a maker-stated current offer, not final inventory, sale, pickup, fulfillment, official DEF CON issuance, or image-reuse permission.
Official shop source stating that preregistration guarantees a DEF CON 34 Human badge, that badges must be picked up onsite, and that onsite registration begins Thursday, August 6, 2026.
Public repository for an optional external DC34 capture-ring design. Its README describes a two-piece print from one STL and says the geometry was derived photogrammetrically rather than from an official DEF CON drawing. It does not establish a tested physical fit, official status, manufacture, distribution, or a reusable-image grant; no repository license was recovered in this pass.
Uberflux listing for a third-party $4 adapter intended by its maker to rotate an SAO 180 degrees for DEF CON 34. It explicitly says it does not solve the 3.0 V supply constraint and does not establish an official defect, universal compatibility, a pinout, or image-reuse rights.
Maker storefront source for a claimed 5 V-to-3.3 V standalone SAO source intended to run an SAO without a host badge. It is recorded as a third-party DC34-adjacent power/display companion, not as an official DEF CON item, a host-mounted main-badge add-on, a verified safety/compatibility result, or an image-reuse grant.

Upstream Baochip-1x hardware source tree for the announced DC34 chip context: README scope, taped-out RTL, VexRiscv configuration, simulation/FPGA material, and CERN-OHL-W-2.0 repository license. It is not a final DC34 badge PCB, BOM, or firmware release.
Maker-published README for a two-piece 3D-printed capture ring intended to hold the DEF CON 34 badge at a chosen rotation. It says one STL is printed twice and combined with user-supplied hardware or zip ties and a dual-clip lanyard; the maker also says the geometry was derived photogrammetrically and is not an official DEF CON drawing. This source establishes an optional design proposal, not a verified fit, port orientation, electrical result, official accessory, production run, delivery, or image-reuse permission.

Its README calls it a BIO uploader for a DC34 badge and documents USB-serial program loading, SAO-I/O selection, and clock configuration. It establishes a user-tooling surface, not complete embedded firmware, final hardware, safe settings, event-unit parity, or a delivery record.
Creator-published KiCad archive for the DC34 core module, released under CERN-OHL-W-2.0. It establishes a public core-module hardware-design trail, not a full carrier-board archive, an all-unit BOM, production test evidence, or permission to reuse repository visuals.
Public Apache-2.0 source at the creator-named `bunnie` account. Its README calls it an image uploader for a DC34 badge and documents black-and-white 128×128 image transfer over USB serial. It establishes a user-tooling surface, not physical display technology, a particular installed image, final firmware, event distribution, or image-reuse permission.
Creator-published source for the DC34 vault application. Its README identifies the conference UI, encrypted-QR light exchange, detachable-core token mode, and source-release context. It warns that custom firmware wipes provisioned secrets; it does not establish every issued unit's final software state, a universal security result, or a blanket media license.
Primary maker storefront source for the third-party $4 180-degree adapter, its stated SAO orientation use, its explicit 3.0 V warning, its Friday/Saturday Badge Life Booth pickup options, and current 593-sold / 7-remaining meter. The maker's 'upside-down' characterization is retained as maker context, not as an official defect determination or universal-compatibility claim; the product images have no reusable-image permission.
