Operational history
Issues & Camp Impact
The official page asks attendees who are not based in New Zealand to hand over the seed-paper badge at merch-desk recycling boxes.
The catalogue preserves the badge's material lifecycle and avoids treating a plantable local artifact as universally exportable swag.
The walkthrough documents the solved path, but this pass does not preserve all original challenge pages, audio, images, or server state.
The catalogue summarizes the puzzle structure while avoiding claims that the live challenge infrastructure remains complete.
The walkthrough documents the solved path, but this pass does not preserve all original challenge pages, images, or server state.
The catalogue summarizes the puzzle structure while avoiding claims that the live challenge infrastructure remains complete.
The recovered source trail documents the board role, Raspberry Pi Zero WH target, major peripherals, lab use, and kit price, but this pass did not recover schematic, PCB, BOM, firmware, or exact sensor-part correction beyond the page text.
The entry keeps claims to the official component list and training context while avoiding unsupported board-revision, driver-source, or manufacturing-quantity details.
The recovered official source does not identify the badge material, electronics, firmware, serial behavior, puzzle files, or whether the badge challenge used the attendee tag itself.
The catalogue keeps the record to identity-badge and challenge evidence until a direct technical source appears.
The recovered official sources do not document badge electronics, firmware, microcontroller, serial interface, display, radio, NFC, QR behavior, or a badge-specific challenge repository.
The catalogue keeps component-level fields empty until direct badge documentation is recovered.
Kiwicon 7 Badge
note
The recovered official sources do not disclose whether the 2013 credential had electronics, special printing, serial numbers, NFC, QR behavior, or any programmable surface.
The catalogue keeps the record to badge assembly and pickup evidence until direct badge documentation appears.
The recovered official sources do not disclose whether the 2015 credential had electronics, special printing, serial numbers, NFC, QR behavior, or any programmable surface.
The catalogue keeps the record to visible badge and pickup evidence until direct badge documentation appears.
The recovered official sources do not disclose whether the Kiwicon X credential had electronics, special printing, serial numbers, NFC, QR behavior, or any programmable surface.
The catalogue keeps the record to badge/lanyard identity and pickup evidence until direct badge documentation appears.
The official source documents supplied electrical components, tools, soldering, IC programming, and Arduino IDE use, but not the exact PCB, chip, battery, display, schematic, or firmware.
The record avoids inventing component-level details until a workshop handout, schematic, or first-hand writeup is recovered.
The recovered official sources describe the badge as a glow-in-the-dark star, but do not document materials, maker, print method, dimensions, or production run.
The catalogue keeps the record to lanyard and star-badge evidence until direct artifact documentation appears.
The official CHCon 2018 source proves identification tags/badges and badge challenges but does not prove that the attendee credential was an electronic PCB badge.
The record is modeled as an identity and challenge artifact so the CHCon lineage expands without unsupported microcontroller, firmware, display, radio, NFC, or CTF-on-badge claims.
The CHCon 2019 sources prove identification tags/badges and nearby electronic CTF challenges, but not an electronic attendee badge.
The entry separates identity-badge materials from CTF electronics so the record does not invent a PCB credential.
Kiwicon 7 Badge
note

The record keeps the Kawaiicon badge as a material identity artifact rather than upgrading it into a PCB badge without evidence.
The official Purplecon diary proves a lanyard badge, but not an electronic attendee badge.
The entry is modeled as a glow-in-the-dark identity artifact and avoids unsupported PCB, firmware, display, radio, NFC, or CTF claims.
The Kiwicon 2038 visual uses Kristina D.C. Hoeppner / 4nitsirk's Flickr documentary photo `Kiwicon 2038AD name badge` under CC BY-SA 2.0.
The entry now has a real rights-cleared lanyard/name-badge photo while preserving the rule against generated, placeholder, social-media, conference-gallery, or uncleared event imagery.
LCA2019 Donkey Car
note
The source trail proves a Donkey Car robotics and machine-learning kit used in the Open Hardware Miniconf, not a conference-wide admission credential.
The entry is modeled as an LCA hardware-kit artifact in the badge lineage while avoiding claims about attendee identity-badge issuance.

The record remains source-backed and image-free rather than copying blog or art-page images without complete provenance.
CHCon 2025 Badge
note
The designer writeup documents source-file names, firmware architecture, and implementation details, but the current source trail did not recover a reliable public firmware repository, schematic, board-file archive, or license statement.
The dossier can now describe the implemented firmware architecture from a primary source while still avoiding unsupported repository, schematic, image, or reuse-rights claims.
LCA2019 Donkey Car
note
The public trail documents the Donkey Car kit, Raspberry Pi camera control, TensorFlow training-data workflow, participant assembly, and self-driving attempts, but this pass did not recover a stable schematic, BOM, model archive, firmware repository, kit quantity, or explicit project license.
The record keeps hardware and software claims to official event context and first-hand evidence until deeper project archives are recovered.
The Kākācon 2021 source trail proves a sticker-backed badge challenge, not an electronic badge.
The entry preserves the printed challenge artifact without inventing PCB hardware, firmware, RF, display, or battery behavior.

The entry is modeled as a hardware training kit in the linux.conf.au/Oceania lineage rather than an official admission badge.
The official page proves a badge created in a training workshop, not necessarily the main attendee credential or a public mass-distributed badge.
The compendium keeps the artifact in the Kiwicon lineage while distinguishing a classroom build from a con-wide badge issue.
