maker-documented electronic badge platform
Public documentation identifies an RP2040, microSD/local media, LiPo power path, 3.5 mm audio chain, addressable LEDs, USB-C, infrared components, and an SAO header. It records a high-level technical surface rather than a verified final BOM, pinout, voltage/current budget, cell specification, charger protection result, electrical test, compatibility matrix, compliance record, or safe-modification guide.

commit-pinned firmware and revision documentation
Maker-published firmware notes that distinguish rev-1 and rev-2 implementation details around audio, storage, and infrared behavior. They establish a documented revision trail, not a signed release, firmware-to-unit hash, security review, guaranteed update/recovery outcome, event media set, or unit-wide parity claim.

commit-pinned maintainer project update
Maintainer commit whose message says the described boards were fabricated, assembled, and playing music, and that every badge's silkscreened QR code points to the repository. It is primary source-publisher evidence of a physical maker run, not evidence of DEF CON or venue authorization, a named event programme, quantity, purchaser or recipient entitlement, delivery outcome, credential role, or independently verified condition of every unit.

commit-pinned maker badge documentation
Primary maker documentation for the wearable silent-disco framing, local DJ mixes, headphones, music-linked lighting, infrared badge-to-badge sync, RP2040, MicroPython/native MP3 decoder, four addressable LEDs, USB-C, sawtooth edges, current universal UF2, public KiCad sources, fabrication files, and Pikkolo Assembly design/build credit. It does not independently verify an organizer relationship, completed distribution, final unit parity, or reusable image rights.

public independent maker badge repository
Public repository titled DEF CON Silent Disco Badge, described by its publisher as an RP2040-based DEF CON silent-disco badge with KiCad project and tooling. It establishes an independently published event-associated technical project, not DEF CON authorization, a silent-disco programme role, admission function, seller, price, run size, allocation, pickup, recipient handoff, support commitment, or image-reuse permission.

repository source and hardware-file license
Root MIT-style license naming Zach Dicklin as 2026 copyright holder and expressly covering software, associated documentation, and hardware design files. It supports repository-source attribution and licensing only; it does not identify or clear any specific documentary badge photo or selected upstream raster for local publication, establish DEF CON trademark authority, or determine third-party component/media rights.

versioned maker hardware documentation
Public versioned documentation describing the project hardware architecture, including its RP2040, local-media, LiPo, audio, infrared, LED, and SAO design surface. It is a design-document source, not a final production manifest, exhaustive verified BOM, safety/compliance result, battery validation, headphone/SAO compatibility guarantee, or proof that all fabricated boards share one revision.

Primary maker firmware/revision document for rev-1/rev-2 behavioral and hardware-context distinctions. It does not supply a signed/tagged production release, source-to-device mapping, independent security review, support policy, event configuration, or evidence that every physical badge uses the documented state.

Primary versioned maker design document for the board's high-level RP2040, storage, power, audio, infrared, LED, and SAO architecture. It does not prove a complete/final production design, fabrication quantity, assembly inspection, electrical safety, compliance, tested compatibility, or matching physical unit.

Primary maintainer update stating the boards are fabricated, assembled, and playing music, and that every badge's silkscreened QR points to the repository. It supports only a source-publisher physical-run claim; it does not establish recipient allocation, handoff, quantity, final component/revision parity, organizer endorsement, event access, or an independent post-event report.
