ARM, 2.4 GHz, LCD, USB, and button badge

Four-button, four-LED challenge badge

Independent electronic badge and Pirate Flag SAO bundle with a scheduled DC33 BadgeLife drop
BigTaro's Tindie listing calls this the Submarine Badge & Pirate SAO and describes a $150 Defcon-pickup preorder. It frames the electronic artifact as an interactive underwater world with CTF package deliveries in DEF-SEA, pirate battles, underwater cults, Atlantis, hardware/software puzzles, and soldering challenges. The source says it has a super-bright round display, more than six buttons, one SAO port, exposed extra GPIO, a fully-programmable claim, an exclusive Pirate Flag SAO bundle, stickers, and an interaction with Gunslinger-B-Gone. BigTaro's own Submarine page supplies a live dashboard-like maker surface, and the DEF CON 33 Creator Events List independently schedules a Friday BadgeLife Community Table 1 drop naming Submarine alongside FrogStar and FightDystopia. These sources establish a real independent electronic-badge bundle and a scheduled 2025 event activity, not an official DEF CON credential, confirmed attendance or handout outcome, production count, electrical design, firmware source release, or reusable-image rights.

The official event site confirms the completed May 28-29 Gothenburg conference, while a contemporaneous attendee report credits Carl Vargklint's badge work. Allocation and delivery are not documented.
