A modified open-source VR headset, based on the Relativty project, that swaps the standard IMU tracking setup for a Kauai Labs navX-MXP sensor board (originally built for FRC robotics), bridged to an Arduino through custom firmware. The navX's onboard sensor fusion coprocessor replaces the typical raw-IMU-plus-software-fusion approach, aiming for smoother, more stable head tracking. Includes 3D-printed housing modifications, upgraded lenses, and a from-scratch serial translator to get the navX talking to SteamVR.
