Blinky Gothenburg tram badge
A conservative first-pass record for Security Fest's 2022 tram-inspired badge, remembered in later badge writeups as a fun blinky object inspired by Gothenburg trams with a Rickroll reference.
People
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.
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.
Public sources currently support only a cautious hardware description: a tram-inspired blinky badge. Component, microcontroller, power, PCB, connector, and production details should wait for a primary 2022 badge writeup or original design files.
The available retrospective evidence mentions a Rickroll reference, but does not expose firmware, serial behavior, challenge flow, app store links, or update paths. This record therefore treats the software surface as an unresolved archival gap.
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.
