ESP32-WROOM-32 audio badge with Alexa experiment path
LayerOne 2018's electronic badge was an ESP32-WROOM-32-based audio and network badge documented by the official HHV archive, Hackaday's event report, the linked CharlieX ESP32_Alexa repository, and mmca's public hardware notes.
Independent 25-slot Simple Add-On host badge; later DEF CON 34 roster continuity
Coruscant Ventures' official SAO Many SAOs Badge page identifies the object as a DEFCON 33 product, presents it as a 25-design Simple Add-On display platform, and says its outer LEDs require the separate SmartAO SAO. The maker's public technical README says the badge has two pre-installed 18650 batteries, USB and barrel-connector power/charging paths, up to 25 SAO slots, and an approximately 300 mA at 3.3 V total SAO budget when using charged batteries. A July 2026 public DEF CON 34 Badgelife response marks SaO MANY SAOs as Update to Existing, gives an $80 price and Venmo acquisition note, and repeats 25 SAO slots plus a 360 by 360 mm size. The current roster does not identify a changed board or new revision, so this is one independently documented DEF CON 33 host badge with a later availability/continuity record, not a duplicate DEF CON 34 artifact, official credential, completed sale, confirmed delivery, or rights-cleared image.
Published pre-event RP2354 BadgeLife village badge; allocation and handoff unverified
Badge.Life's public archive documents Badgey Bodgerton as the Badgelife Village Badge for DC34 / 2026. Its published guide names an RP2354 microcontroller with integrated flash, eight addressable RGB NeoPixel LEDs, three user buttons, one user-installed 3 mm challenge LED and polarized buzzer, USB-C power, USB CDC serial CLI, UF2 firmware flashing, a single-cell 18650 battery with charging and protection circuitry, two Simple Add-On v2 headers, and an infrared receiver. It also documents a supplied bodge-wire challenge and supplied LED/resistor/buzzer challenge parts. This establishes a distinct, technically documented pre-event BadgeLife village electronic badge, not proof that DEF CON designed, issued, or will distribute it; that it is a Human admission credential; that every participant receives one; that a final badge run, pickup, or delivery occurred; or that any displayed image is cleared for reuse.
Pre-event sold-out XIAO ESP32S3 EMF BadgeLife release
NilbinSec's live Uberflux listing identifies the Spectre Sniffer Badge as a limited DEF CON 34 release. At this August 3, 2026 source pass, the $80 listing shows 80 sold and no units remaining. Its maker-published description names a XIAO ESP32S3, a live EMF detector with a real-time spike graph, a randomized-word Spirit Box whose output rate follows the stated EMF signal, a SAO v1.69bis connector with I2C, one included Pac-Man Ghost SAO in one of four colors, a protected 18650 battery and lanyard, and one- and two-player arcade games. The seller says release is pickup only at the BadgeLife Village and announced LVCC locations, with missed drops donated at closing ceremonies. This is a source-backed pre-event independent BadgeLife record, not proof of final handoff, finished firmware, component-level engineering, instrument accuracy, electrical safety, official DEF CON admission status, or reusable-image rights.
