Celestial Wayfinder Badge

A LoRa mesh communicator designed to let you ping where you are and find your way to what's happening. The Wayfinder has a cyberpunk industrial design with customizable and interchangeable 3D printed parts, clicky mechanical keyboard switches, haptic feedback, and an OLED screen.

A combination of GPS and WiFi geolocation ensures you can find your way indoors and outdoors.

Running on an ESP32, the firmware is open source and extensible, and can be easily updated via the USB-C port. The port recharges the onboard lithium-ion battery and the hardware has been battle-tested through 5+ revisions across conferences, festivals, and burns.
