Maker-documented ATtiny85 Hardware Village CTF badge soldered in Goa
The official Seasides and HW101 pages establish a Goa Hardware Hacking Village where people soldered take-home badges and worked on a hidden hardware/firmware challenge. A public project-owner archive calls a concrete board the Seasides 2026 Roulette Badge, says that more than 300 participants assembled it live, and publishes its C firmware, schematic, and Gerbers. The archive makes this a source-backed maker-documented instance of the village badge, but the official event pages do not independently name the Roulette design or confirm that every village or conference badge used that exact final configuration.
