BSides Cheltenham 2023 · United Kingdom · 2023
ATtiny402 DeLorean PCB-art conference badge
An electronic PCB-art conference badge documented by its maker and badge sponsor, Punk Security, for BSides Cheltenham 2023. Punk Security's own dated event listing identifies its June 3 Cheltenham appearance as that year's badge-sponsor engagement, names a talk on building the BSides Delorean badges, and describes them as functional conference badges. The public `bsides-cheltenham-2023-badge` repository calls the artifact the Delorean badge, reports that parts sold for badge completion on the day raised more than £300 for Mind, and preserves EAGLE, Gerber, library, and Arduino firmware material. Its parts list names an ATtiny402, button, CR2032 clip, NeoPixel, and 3528 blue LED. The reviewed sources do not establish organizer-side 2023 confirmation, venue, production quantity, attendee allocation, individual handoff, final unit-by-unit configuration, completed assembly count, safety validation, or reusable image provenance.
People
Punk Security's dated event listing identifies it as BSides Cheltenham's 2023 badge sponsor, and its public repository identifies the Delorean Badge and preserves source material. This credit reflects the publicly named sponsor/maker/archive roles without assigning organizer authority, attendee allocation, safety, final production, or image rights.
SourceIt adds a source-backed United Kingdom Security BSides electronic-artifact lineage that is more specific than a generic sponsor mention: the dated maker listing directly identifies functional conference badges, while the contemporaneous source archive identifies the badge, source files, and a limited on-day charity-fundraiser account. The dossier keeps that evidence bounded rather than treating it as an organizer recap, a final manufactured run, or proof that every attendee received or completed the same badge.
The public maker archive describes an ATtiny402 microcontroller, one surface-mount button, CR2032 battery clip, NeoPixel addressable LED, and 3528 blue LED, and preserves EAGLE board/schematic/custom-library and Gerber material. The sources do not establish final component substitutions, battery brand/capacity, power budget, electrical limits, production revision, assembly quality, manufacturing test plan, certification, compliance, or safety outcome for every physical unit.
Punk Security's source archive preserves an Arduino firmware sketch for the Delorean Badge. The record does not reproduce connection, flashing, configuration, modification, or hardware-assembly directions and does not claim a tagged release, signed binary, source-to-unit mapping, support policy, or all-unit firmware parity.
Punk Security's dated event listing says it was BSides Cheltenham's 2023 badge sponsor and that Simon Gurney would talk about building functional Delorean conference badges. Its repository says parts to complete those badges were sold on the day and raised more than £300 for Mind. That maker-side fundraiser account is retained as historical event context without asserting organizer confirmation, a uniform attendee experience, exact sales or completion count, or an individual donor 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.
Punk Security's public repository identifies the Delorean badge as a BSides Cheltenham electronic conference artifact. It does not establish organizer-side confirmation, attendee-wide allocation, final unit parity, or image rights.
Signal sourceThe repository's parts list names a NeoPixel addressable LED. The signal does not establish LED package substitutions, current budget, brightness, power behavior, or final-unit parity.
Signal sourceThe repository's parts list names a CR2032 surface-mount battery clip. It does not establish battery brand, capacity, polarity protection, power budget, runtime, electrical safety, or final-unit parity.
Signal sourceThe public firmware is an Arduino sketch using the MegaTinyCore interface for the ATtiny4x2 family. This records a source-bounded software lineage, not a supported or safe reconfiguration procedure.

Lifecycle
Punk Security's own historical event listing identifies it as BSides Cheltenham's 2023 badge sponsor, says it would talk about building the BSides Delorean badges, and calls them functional conference badges; its public repository identifies the Delorean Badge. This establishes a maker-side event association without claiming organizer confirmation or that every attendee received or completed a unit.
SourceThe repository says parts to complete the badges were sold on the day and raised more than £300 for Mind. This preserves the narrow maker-reported fundraiser account without claiming an organizer-run campaign, exact purchaser count, exact parts-to-unit mapping, individual donation outcome, completed assembly total, or final badge allocation.
SourceThe repository calls the artifact the Delorean badge and preserves EAGLE board/schematic/custom-library and Gerber material. This records source-described PCB-art and design context without claiming that every delivered unit used an identical final board, art revision, manufacturing finish, or assembly quality.
SourcePunk Security's public repository preserves board, schematic, custom library, Gerber, and firmware material. The archive is linked for provenance without presenting it as a licensed derivative-work, manufacturing, flashing, configuration, or safety guide.
SourceOperational history
The catalogue retains the source-reported charity context without turning it into a verified fundraising audit, universal attendee experience, exact manufacturing total, completed-badge count, or individual donation claim.
The record preserves a source-backed hardware outline without treating public project material as a fabrication, repair, electrical-safety, or universal final-unit specification.
The catalogue links source evidence without presenting it as a supported, reproducible, current, or safe modification or operation workflow.
The catalogue records a source-backed event artifact while keeping maker-side provenance distinct from unrecovered organizer evidence and avoiding a universal allocation claim.
The United Kingdom record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
Source files and public project material are cited as evidence, but no local image, artwork, source file, or brand asset is copied or treated as licensed for reuse.
