JumpAnalyzer is a sports performance hardware project designed to measure and analyze vertical jump characteristics using an IMU sensor.
The system captures acceleration and motion data during a jump and calculates:
- Flight time
- Estimated jump height
- Takeoff dynamics
- Landing impact
This repository contains the hardware design (KiCad) and future firmware/software roadmap.
The goal of JumpAnalyzer is to create a compact wearable device for:
- Basketball players
- Volleyball athletes
- Track & field training
- General athletic performance analysis
The system provides objective performance metrics instead of subjective observation.
Using an IMU (MPU-9250 or similar):
- Detect takeoff moment
- Detect landing moment
- Calculate flight time (t)
- Estimate jump height:
h = g * t² / 8
Where:
- g = 9.81 m/s²
- t = flight time
Future versions may include:
- Peak acceleration
- Jump symmetry analysis
- Repetition tracking
