JumpAnalyzer

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.

🏋️ Project Purpose

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.

🧠 Measurement Principle

Using an IMU (MPU-9250 or similar):

1. Detect takeoff moment
2. Detect landing moment
3. Calculate flight time (t)
4. 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
