Motion Tracking HMD

This project involves the development of a motion tracking device for HMD. It includes milestones such as mounting to visor, measuring outputs, and calibrating microcontroller. Integration steps include attaching servos and accelerometers, connecting to a computer, and additional wow steps. The device driver will be wireless and include features like pitch and yaw, re-centering, and extra function buttons. The range of motion will be expanded and the BOM includes LCD glasses, accelerometer, microcontroller, servos, DAC, and misc circuitry.
