Artistic sonic RP2040 badge
An official Ekoparty 2025 electronic badge record for a customizable artistic and sonic badge with RP2040 control, I2S DAC audio, headphone and speaker amplification, rechargeable USB-C power, NeoPixel backlight LEDs, resistive touch sensors, sequencer, sample playback, synth behavior, and effects.
Completed independent three-radio ESP32-S3 RF-awareness badge
The public Friend or Foe project archive documents a three-board ESP32-S3 badge shown at DEF CON 34 Packet Hacking Village. Its hardware documentation records a 45-badge DEF CON run and the project root describes a wearable, passive RF-awareness platform with an uplink/display controller and dedicated BLE and Wi-Fi scanner boards. Packet Hacking Village's official DEF CON 34 programme independently establishes the completed village setting and the Friend or Foe presentation. These sources establish a completed independent electronic project, not an official DEF CON Human badge, conference-wide handout, admission credential, or recipient ledger.
Pre-event RP2350B interactive Simple Add-On planned for DEF CON 34
ParallelLogic's Uberflux listing, public MalO_SAO source/design repository, and first-hand Hackaday.io project diary document a planned DEF CON 34 Simple Add-On based on the SCP-1471-A MalO setting. The marketplace's August 4, 2026 snapshot lists $50, 43 sold, and 57 remaining. The repository says the units are intended for online sale and DEF CON 34 handout in August 2026, identifies an RP2350B, 16 MB external flash, 1.5-inch 128 by 128 grayscale OLED, standard six-pin SAO header, USB-C, capacitive touch, potentiometer, buzzer, microphone, hall sensor, IMU, ambient-light sensor, IR transmit/receive, NFC/RFID, and LED banks. Its project diary confirms the work is ongoing and documents early prototype testing. The repository declares the work CC BY-SA 3.0. This is a source-backed pre-event independent badge record, not proof that a final revision has shipped, that all promoted functions are complete, that every radio/sensor interaction is safe or private, that a named third-party lore asset grants image rights, that the project is DEF CON-issued, or that it grants admission.
Pre-event RP2350 temperature-measuring Simple Add-On for DEF CON 34's BCCC
The live maker listing for The Beer SAO, the public `aerospace-venoms/BCCC_Temperature_SAO` source tree, and BCCC's own DEF CON 34 page document an independent temperature-measuring Simple Add-On associated with the Beer Chilling Contraption Contest. The marketplace's August 4, 2026 payload shows a $45, 150-unit presale with 28 sold and 122 remaining, two BadgeLife Village pickup slots, and no shipping. It describes a roughly 100 mm beer-cup SAO with a waterproof temperature probe, triple seven-segment display, RP2350 with 2 MB flash, USB-C, and a supplied 180-degree adapter for the upside-down DC34 host ports. The source tree identifies an RP2350A, W25Q16 flash, DS18B20 temperature sensor, RGB-independent brightness control, Pico-SDK firmware, KiCad design files, a versioned UF2, and batch programming/soak-test tooling; it says BCCC winners receive copies while stock lasts. This is a source-backed pre-event independent badge record, not proof of final manufacture, pickup, contest results, host compatibility, temperature accuracy, safety, final firmware, DEF CON organizer endorsement, conference admission, or reusable-image rights.
