Little Shop of Horrors ATtiny402 soil-sensor PCB badge
An electronic PCB badge documented by its maker and badge sponsor, Punk Security, for BSides Newcastle 2024. Punk Security's own dated event listing identifies its October 5 Newcastle appearance as that year's badge-sponsor engagement and says Simon Gurney presented the making of the conference badge. The public `bsides-newcastle-2024-badge` archive calls the artifact the Little Shop of Horrors Plant Badge, says it was given out at BSides Newcastle, and describes it as a working soil sensor. It preserves EAGLE, EasyEDA, Gerber, firmware, board-image, and schematic material, and names an ATtiny402, button, CR2032 clip, 5050 NeoPixel, and 6.8 kΩ resistor. The reviewed sources do not establish organizer-side 2024 confirmation, venue, production quantity, attendee allocation, individual handoff, final unit-by-unit configuration, measurement performance, safety validation, or reusable image provenance.
People
Punk Security's dated event listing identifies it as BSides Newcastle's 2024 badge sponsor, and its public repository identifies the Little Shop of Horrors Plant 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 extends the source-backed BSides Newcastle lineage with a clearly named event artifact rather than assuming that an unverified past event had no electronic badge. The dossier makes its provenance boundary visible: the maker's dated sponsor record and separate distribution statement are strong artifact evidence, but they are not substituted for an organizer recap, recipient ledger, final production record, or a soil-sensing performance guarantee.
The public maker archive describes an ATtiny402 microcontroller, one surface-mount button, a CR2032 battery clip, one 5050 NeoPixel addressable LED, and a 6.8 kΩ 1206 resistor. It says the board used full-colour silkscreen and preserves EAGLE board/schematic, an EasyEDA project, and Gerber material. The sources do not establish final component substitutions, battery brand/capacity, power budget, electrical limits, sensing circuit calibration, production revision, assembly quality, or safety outcome for every physical unit.
Punk Security's source archive preserves an Arduino firmware sketch for the source-described Plant Badge. The record does not reproduce sensing, 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 Newcastle's 2024 badge sponsor and that Simon Gurney would give a talk on making the year's conference badge. The later source archive calls the physical form the Little Shop of Horrors Plant Badge and says it was given out at BSides Newcastle as a working soil sensor. That maker-side event account is retained as high-level badge context without asserting a tested field result, a universal attendee experience, or an organizer-confirmed distribution programme.
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 Little Shop of Horrors Plant Badge as an electronic artifact given out at BSides Newcastle. It does not establish organizer-side confirmation, attendee-wide allocation, final unit parity, or image rights.
Signal sourceThe repository's parts list names one 5050 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 sensing, reconfiguration, or modification procedure.

Lifecycle
Punk Security's own historical event listing identifies it as BSides Newcastle's 2024 badge sponsor and says it would present the making of that year's badge; its public repository identifies the Little Shop of Horrors Plant Badge and says it was given out at BSides Newcastle. This establishes a maker-side event association without claiming organizer confirmation or that every attendee received a unit.
SourcePunk Security's repository calls the Plant Badge a working soil sensor. This preserves the source-described feature at a high level without publishing sensing procedure, calibration, measurement accuracy, environmental limits, safe operating conditions, field result, or a universal user experience.
SourceThe repository calls the artifact the Little Shop of Horrors Plant Badge, describes full-colour silkscreen, and preserves EAGLE, EasyEDA, Gerber, board-image, and schematic material. This records source-described physical/art 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, EasyEDA, Gerber, and firmware material. The archive is linked for provenance without presenting it as a licensed derivative-work, manufacturing, sensing, flashing, configuration, or safety guide.
SourceOperational history
The record preserves a source-backed hardware outline and soil-sensor description without treating public project material as a fabrication, repair, measurement, 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.
The catalogue makes the source-described badge feature discoverable without inferring tested performance, universal participation, a completed challenge, individual outcomes, or a safe operating workflow.
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.
