publicly documented sensing and display surface
The source tree names a DS18B20 one-wire sensor on GPIO 16 and three common-anode seven-segment displays multiplexed through a 74HC595, while the listing describes a waterproof probe and triple display. The firmware source says a missing DS18B20 produces a display fallback and logs die temperature to USB serial. No reviewed source provides temperature calibration, traceability, environmental limits, response time, error bounds, food-contact certification, or a suitable-use guarantee.

current maker marketplace product page
Live maker-controlled Uberflux product page and serialized payload for The Beer SAO. It establishes the observed $45 / 150-total / 28-sold / 122-remaining pre-sale snapshot, two announced DEF CON 34 BadgeLife Village pickup labels, no shipping option, included 180-degree adapter, physical/package claims, and maker-described functions. Product imagery has no stated reusable license or explicit permission basis.

official contest page
BCCC's own 2026 contest page placing its twenty-first Beer Chilling Contraption Contest at DEF CON 34, Las Vegas Convention Center, August 6–9. It defines the contest context and says contestants need DEF CON badges, but does not describe the Beer SAO as an official Human badge, admission item, or universal contestant award.

public hardware and firmware repository
Public `aerospace-venoms` source tree for the BCCC Temperature SAO. Its README documents the BCCC/DEF CON 2026 connection, RP2350A/W25Q16/DS18B20/display/USB-C/SWD hardware, dual-core Pico-SDK firmware, KiCad tree, UF2, build/flash guidance, batch programming, and soak-test tools. It is a public technical source, not proof that every marketplace unit carries the same revision or a reusable-image grant.

public software and hardware license declaration
Root license file declaring WTFPL v2 and copyright by Ames Evans. The file says firmware was developed with Claude. Its broad code/design license does not identify one physical badge photograph or repository image as a rights-cleared documentary hero asset, nor does it establish final event-unit configuration.

Primary license source declaring WTFPL v2 and copyright by Ames Evans, with the source-authored note that firmware was developed with Claude. It permits broad copying/modification on its own terms but does not map repository or marketplace media to an attributable, factual, rights-cleared hero image or prove deployed firmware provenance.
