Con firmware release

The repository README links the BruCON0xA release as the firmware version installed on the conference badge, preserving the shipped build rather than only source head.

Issues & Camp Impact

BruCON 0x0A Badge note

missing rights-cleared image · local project policy · needs licensed original replacement

No BruCON 0x0A Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The Belgium record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.

BruCON 0x0A Badge note

production crunch · event retrospective · historical

Organizers reportedly stayed awake through the night soldering the badges before the event.

This preserves the operational reality behind the badge, not just the attendee-facing utility.

BruCON 0x0A Badge note

shipped firmware bugs · repository README · historical

The repository README explicitly points to the firmware version that was on the conference badge and notes that it is preserved with its bugs.

The archive should treat the tagged release as historically important even where later source changes may differ from the build attendees actually used.

BruCON 0x0A Badge note

source-depth caveat · event retrospective and repository review · schematic-backed review still useful

The repository review confirms the source tree, firmware release, KiCad/Gerber package, LCD, ADC, Wi-Fi, URL, menu, map, schedule, and server-side workflow, but the page still avoids unsourced chip-level claims that require careful schematic/BOM extraction.

The dossier is now stronger than a first-pass retrospective record while still keeping component lists tied to inspectable files.
