Overview

The FIYR Pod is a wearable GPS sports-tracking device designed to be worn by athletes during activity.

I was responsible for end-to-end device build and fulfillment, of the device and it’s accompanying charging case, owning the physical product from ordering materials, to PCB fabrication, through final assembly, testing, and shipment.

My Role

I served as the primary builder and manufacturing owner for the FIYR Pod, responsible for:

  • Electronics assembly and wireless charging integration
  • Firmware testing and PCB flashing
  • Mechanical assembly and enclosure sealing
  • Quality control, testing, and order fulfillment

This role required close coordination between electrical, firmware, and mechanical systems to ensure reliable performance in a wearable, athlete-facing product.

Electrical Assembly

    • soldered on overcurrent protection capacitors
    • attached charging coil
    • Attached LCD screen
  • Wireless charging circuits
    • Assembled multi-unit charging systems for batch charging
    • Ensured electrical consistency and reliability across all units

Firmware Deployment

  • Flashed devices with production firmware
  • Identified and isolated faulty boards before mechanical sealing
  • Tested PCBs prior to final enclosure to verify functionality
  • Aligned firmware versions between devices and the RF communication tower

Mechanical Assembly

  • Enclosures
    • 3D printed device enclosures in-house using resin printers
    • Installed PCBs with precise alignment of the screen and controls
    • Sealed enclosures using silicone to protect electronics during athletic use
    • Fastened housings closed and performed finishing and polishing

Testing & Quality Control

  • Ran each completed unit through a standardized test process
  • Verified charging behavior, display functionality, and overall operation
  • Acted as the final quality gate prior to shipment

Fulfillment
