DEF CON 34 · United States · 2026
Maker-documented ATtiny1604 soldering-challenge Simple Add-On
NerdFlare's public repository describes a 2026 iFixit Shitty Add On (SAO), while its repository description labels the project an iFixit DEFCON 2026 SAO. The commit-pinned README documents a physical PCB art badge with multiple LED animations, an interactive surface-mount soldering challenge, user-programmable firmware, an ATtiny1604-SS target, PlatformIO/Arduino code, and KiCad design files. A dated July 18 source commit says "Version 0.1 - FINAL: art, code, and PCB. 1000 made for DEFCON34." Those are direct project-publisher statements sufficient to retain a distinct pre-event DEF CON 34 artifact, but not proof of organizer issuance, iFixit corporate publication, event authorization, attendee allocation, actual handoff, admission function, a final unit-by-unit configuration, or reusable-image rights.
People
NerdFlare's commit-pinned README lists iFixit as one of three collaboration parties. This records the repository's own attribution wording only; it is not an independently verified corporate authorship, product, sponsorship, event-authorization, manufacturing, fulfillment, or image-reuse credit.
SourceThe README names znjp as a collaboration party. This handle-level attribution is not expanded into a verified real-world identity, sole design/firmware/artwork role, production role, event affiliation, or reuse permission.
SourceThe README names the Cal Poly NerdFlare club in the collaboration statement, while the public repository is under the NerdFlare account. The record does not infer individual authorship, institutional endorsement, manufacturing, event role, or image-reuse authority beyond that published wording.
SourceIt preserves a current, unusually concrete DEF CON 34 SAO source trail: source-controlled firmware, artwork, electrical design, a named microcontroller, a high-level soldering challenge, and a dated maker claim that 1,000 were made. The record keeps the important provenance boundary intact: a project repository and its commit history can substantiate a maker-documented artifact without becoming a DEF CON credential, a completed distribution ledger, or an independently confirmed iFixit announcement.
The commit-pinned README names an ATtiny1604-SS, seven SK6805-EC15 addressable LEDs, a red 0402 tip LED, two reverse-mounted lightning-bolt LEDs, a rear mode button, and four soldering-challenge sensing positions. It also exposes native KiCad schematic and PCB sources. The source set does not independently establish a final production BOM, component substitutions, power source, battery or charging behavior, SAO-header version or pinout, voltage/current budget, host compatibility, enclosure, manufacturing test, electrical safety validation, or that every purported DEF CON 34 unit has this configuration.
The public repository contains a PlatformIO Arduino project for the ATtiny1604 and describes LED animation behavior plus a further animation state tied to its soldering challenge. It also documents a programming surface, but this catalogue does not reproduce connection, build, upload, challenge-completion, or modification directions. No reviewed source establishes a tagged release, immutable production firmware image, source-to-unit mapping, dependency lock, update or recovery policy, support commitment, security review, or final behavior for every physical unit.
The README calls the PCB art badge a collaboration among iFixit, the Cal Poly NerdFlare club, and znjp; its repository description uses DEFCON 2026 wording. The July 18 final-design commit is authored as Zachary Peterson and says 1,000 were made for DEFCON34. These are source-declared project and collaboration details. The source set contains no DEF CON organizer page or iFixit-published page naming this particular artifact, so it is catalogued as a maker-documented event-associated SAO rather than an official Human badge, an admission item, a confirmed sponsor deliverable, or a completed recipient outcome.
Source-backed hardware metadata
Structured technical signals seeded from public badge documentation, repositories, schematics, firmware notes, or event evidence. These fields are designed for filtering, API use, repair planning, preservation, and future Companion Gear matching.
NerdFlare's commit-pinned README identifies a physical 2026 iFixit SAO with source-published firmware, artwork, and KiCad files. Its maker-declared DEF CON association, 1,000-made claim, collaboration, delivery, and final-unit parity remain separately bounded.

Operational history
Code and design material remain linked as evidence, while the record stays image-free and does not present the repository as an open-hardware, software, artwork, or media-reuse grant.
The entry keeps its useful electronic-design trail visible while avoiding an electrical guarantee, universal SAO compatibility claim, safety endorsement, or do-it-yourself operating instruction.
Readers can find the direct maker claim without treating its quantity as an independently audited manufacturing total, a promise to a particular attendee, a distribution ledger, or proof that the event handoff occurred.
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The catalogue retains the named maker project and its source-declared collaboration without promoting it into a DEF CON-issued Human badge, a ticket benefit, an admission item, a confirmed sponsor deliverable, an externally verified iFixit product announcement, or a completed attendee handoff.
