[WIP] Wearable Jump Tracking Device for Athletes

The goal: Detect jump height and frequency for progression tracking and stress monitoring in athletes.

Theory of operation: Continuously monitor for flight time and ground contact time events using a wearable 3-axis accelerometer, and upload the results to a mobile app over BLE.

Jump height, and other metrics such as RSI (reactive strength index) can be derived from flight time using basic projectile motion equations (with an added calibration factor).

Video overlay generated automatically using outputs from on-device processing.

Hardware Design

PCB: There are 4 main ICs used in the design:

Form Factor: The jump tracking device needs to be discreet and unobstructive for in-game use by ball sport athletes (basketball, volleyball etc.). The form factor of the device is a thin clip to be worn on the athlete's waistband (prototype dimensions: ~38mm x 13mm x 7.5mm)
