Attribution Gap

No public individual author, designer, firmware, or team credits have been seeded for this badge yet. Add named credits only when a primary badge-team page, repository, talk, or other source identifies the people or team behind the work.

Why It Mattered

The 2022 badge bridges Security Fest's simple 2018 challenge card and the more elaborate 2023 skyline and 2024 Feskekôrka PCBs. It shows the lineage moving toward local Gothenburg landmarks, playful electronics, and badge-as-souvenir storytelling.

Hardware

Security Fest 2022's badge is a tram-inspired blinky badge, the only hardware description public sources currently support. Component, microcontroller, power, PCB, connector, and production details should wait for a primary 2022 badge writeup or original design files.

Software & Apps

Security Fest 2022's badge software includes a Rickroll reference, per the available retrospective evidence, but no firmware, serial behavior, challenge flow, app store links, or update paths are exposed. This record therefore treats the software surface as an unresolved archival gap.

Lore

Security Fest's later badge authors describe the 2022 artifact as a fun badge inspired by Gothenburg trams. That local-transport motif is useful lore because the next two sourced badges also turned Gothenburg landmarks into wearable electronics.

Issues & Camp Impact

missing rights-cleared image note

No documentary photo of the original 2022 artifact has been cleared for public reuse.

The source-backed facts remain useful while the catalogue withholds imagery until licensed original photos are curated.

Confidence: project provenance
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: Project image provenance and Hackster.io retrospective sources.

retrospective-only source caveat note

The current public source set found for this pass describes the badge through later Security Fest badge retrospectives rather than a standalone 2022 build page.

The dossier keeps the 2022 badge discoverable while avoiding chip-level, firmware, app, production, or author claims until primary sources are recovered.

Confidence: secondary retrospective source
Status: needs primary writeup
Timeframe: first-pass record
Source note: Hackster.io Security Fest 2023 and 2024 badge writeups.
