Pre-event ESP32-S3 LoRa mesh BadgeLife communicator
WyrdWyrks' live Uberflux listing identifies the $150 Celestial Wayfinder Badge as a DEF CON 34 pre-sale. At this August 3, 2026 source pass, the listing shows 5 sold and 95 remaining, with four pickup labels: DC34 Reddit Meetup Wednesday, DC34 Reddit Meetup Thursday, and DEF CON 34 BadgeLife 1 and 2. The maker describes an ESP32-S3, custom four-layer PCB, 128×128 OLED, SX1276 LoRa, GPS, magnetometer/IMU, five Cherry MX-compatible switches, a rotary encoder, 61 WS2812B LEDs, a buzzer, 3D-printed parts, a Li-ion battery, USB-C updating/charging, a LoRa mesh, Wi-Fi geolocation fallback, and a PWA. The public MIT-licensed firmware repository documents v1/v2/v3 platform variants, a 915 MHz SX127x-class LoRa mesh, GPS/status PingMessage data, PlatformIO build paths, RPC, and remote USB/BLE/web configuration; v4.0.0 publishes v3 and v2 binaries. A separate Fusion360/STL CAD repository and web-companion repository are public but have no detected license. This is a source-backed pre-event independent BadgeLife record, not proof of final fulfillment, a final production BOM, radio/regulatory performance, safety certification, universal update compatibility, official DEF CON admission status, or reusable-image rights.
Official open-hardware headless ESP32-C5 wireless-security badge with public KiCad and C5 firmware sources
Electronic Cats' public badge-pwnterrey-2026 repository describes itself as the official Pwnterrey 2026 badge and publishes a native KiCad hardware project plus a CERN Open Hardware Licence v1.2 file. Pwnterrey's official site places the free cybersecurity conference in Monterrey on May 29, 2026; Bishop Fox separately corroborates the date and Rincón Tostitos By Jardín 85 venue. The source documents a portable headless ESP32-C5 RISC-V badge with USB-C serial context, NFC tag-emulation circuitry, and GPS material. Electronic Cats' companion repository calls itself official Pwnterrey 2026 firmware and preserves an ESP32-C5 Marauder-derived source and build trail. These sources establish a real official event badge and public design and firmware references, but not a production quantity, registration-tier allocation, final assembled configuration, completed recipient handoff, final signed release, safe operational use, or reusable badge-image right.
