Issues & Camp Impact

AVTOKYO 2019 Cocktail Blinky Badge note

firmware absence caveat · source-backed but intentionally narrow · documented

The recovered sources describe a soldered RGB blinky badge, transparent PCB design, and coin-cell power, but do not document a programmable MCU, firmware, serial shell, repository, or CTF behavior for the AVTOKYO 2019 badge.

The dossier keeps the artifact as a beginner soldering-village blinky badge instead of inventing software behavior.

AVTOKYO 2019 Cocktail Blinky Badge note

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

No local AVTOKYO 2019 badge photo has been added because the recovered Hackster article images and AVTOKYO event images have not been paired with explicit reuse rights, attribution, and processing notes for catalogue publication.

The AVTOKYO 2019 entry remains source-backed and image-free rather than copying project or event photos without complete image provenance.
