Celestial Wayfinder Badge (DEF CON 34)
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.
