ATtiny402 skull PCB badge
A completed BSides Bournemouth 2025 electronic PCB badge created by the event's badge sponsor, Punk Security. BSides Bournemouth's official 2025 page establishes its Bournemouth 2600-led community cybersecurity conference and reports 200+ attendees; the Security BSides schedule records the August 16 date. Punk Security's own event page identifies it as badge sponsor and calls the artifact a Punk BSides skull badge, while its post-event repository identifies the Skull Badge and preserves EAGLE, Gerber, Arduino firmware, vector, and printed-art material. The archive names an ATtiny402, button, two CR2032 clips, and 5050 NeoPixel. The sources do not establish a production quantity, attendee allocation, individual handoff, final unit-by-unit configuration, safety validation, or reusable image provenance.
People
BSides Bournemouth's official 2025 page identifies the event as organized by Bournemouth 2600 and establishes community conference context. This preserves event context only, not badge design, manufacture, distribution, image-rights, or source-archive ownership.
SourcePunk Security's event listing identifies it as the 2025 BSides Bournemouth badge sponsor, and its public repository identifies the Skull Badge and preserves source material. This credit reflects the publicly named sponsor/maker/archive roles without assigning attendee allocation, safety, event-organizer authority, or image rights.
SourceIt fills an unseeded completed United Kingdom Security BSides artifact with official conference context, a dated maker/sponsor statement, and a public design-and-firmware archive. The record separates a real sponsor badge from unsupported assumptions that all 200+ reported attendees received the same unit or that a reference parts list maps exactly to every physical build.
The public archive describes an ATtiny402 microcontroller, one surface-mount button, two CR2032 battery clips, and one 5050 NeoPixel addressable LED, and preserves EAGLE board/schematic, Gerber, vector, and silkscreen-art material. Its README says the stated parts match the BSides Cheltenham 2024 badge reference list. The sources do not establish final component substitutions, battery brand/capacity, power budget, protection behavior, runtime, electrical limits, production revision, assembly quality, or safety outcome for every physical unit.
Punk Security's source archive preserves an Arduino firmware sketch for the Skull Badge. The record does not reproduce flashing, configuration, connection, 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.
BSides Bournemouth describes its 2025 edition as a grassroots community cybersecurity conference organized by Bournemouth 2600, a local chapter of the global 2600 hacker community. Punk Security's dated event listing says it was the 2025 badge sponsor and invited people to collect its skull badges at its stand. The public archive calls the physical form the Skull Badge; sponsor evidence and reported attendance are not treated as a production or recipient ledger.
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 Skull Badge as the BSides Bournemouth 2025 electronic badge. It does not establish attendee-wide allocation, final unit parity, or image rights.
Signal sourceThe repository's stated parts list names one 5050 NeoPixel addressable LED. The signal does not establish package substitutions, current budget, brightness, power behavior, or final-unit parity.
Signal sourceThe repository's stated parts list names two CR2032 surface-mount battery clips. It does not establish battery brand, capacity, 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 event listing says it was BSides Bournemouth's 2025 badge sponsor and identifies Punk BSides skull badges, while its public repository identifies the Skull Badge for the event. This establishes a maker/sponsor event association without claiming the event organizer owned the archive or that every attendee received a unit.
SourceThe maker says the badge used full-colour printed PCB artwork and an EasyEDA preparation path. This records source-described manufacturing context without inferring a complete supplier record, production count, final materials, inspection plan, or quality outcome.
SourceThe repository calls the artifact the Skull Badge and preserves vector and printed-board-art material alongside EAGLE and Gerber sources. This records the documented form without claiming every delivered unit used an identical final board, art revision, assembly quality, or manufacturing finish.
SourcePunk Security's public repository preserves EAGLE, Gerber, Arduino firmware, vector, and printed-art material. The archive is linked for provenance without presenting it as a licensed derivative-work, manufacturing, flashing, or safety guide.
SourceOperational history
The record preserves a source-backed hardware outline and its reference-list limitation without treating it as a complete fabrication, repair, electrical-safety, or universal final-unit specification.
The catalogue records a completed event-associated electronic badge without turning sponsorship or attendance evidence into a universal allocation claim.
The catalogue links source evidence without presenting it as a supported, reproducible, current, or safe modification workflow.
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.
