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.
Champion-tier nRF52840 LoRa Meshtastic badge
The Ekoparty 2026 electronic badge, included with the Champion ticket tier while supplies last. On October 3, 2026, four days before the October 7-9 Buenos Aires conference, badge-team member Nicolas Restbergs (Fábrica Marciana) published the ekoparty-badge-2026 repository, which calls itself the firmware for the official Ekoparty 2026 badge: a Meshtastic node on an nRF52840 with an SX1262 LoRa radio, a 0.96-inch OLED, Bluetooth pairing with the Meshtastic phone app, a piezo buzzer, six rear SK6812 backlight pixels, and a separate status pixel. The release v1.0.3 adds a schematic, pin map, user manual, and the EKOBOOT bootloader image; v1.0.4 followed on October 5, and an EasyEDA Pro project and a low-temperature-solder fragility warning were added on October 8, during the conference. By October 9, 2026 Ekoparty's own event page carried an EKO BADGE ELECTRÓNICO section describing the badge as a customized Meshtastic build that works off-grid and links to the badge team's guide, and an October 12 attendee writeup confirms the event took place with Meshtastic Eko Badges in hand. Production count and allocation stay unconfirmed.
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.
