# PingMyGear – Online Hardware & Peripheral Diagnostics Suite
> PingMyGear (https://pingmygear.com) is a free, 100% client-side web application for diagnosing computer hardware and gaming peripherals in real time without software installation.

## Core Capabilities
- **Mouse Diagnostics**: Double-click detection (<80ms chatter threshold), hold drop & drag interruption tester, real-time switch signal oscilloscope, polling rate (Hz) benchmark, CPS click speed, sensor movement jitter, and browser input latency.
- **Keyboard Diagnostics**: Full 104-key visual keyboard matrix, N-Key Rollover (NKRO) anti-ghosting test, per-key switch chatter & bounce detection, hold duration analysis, and dedicated Numpad keypad tester.
- **Audio & Headphone Diagnostics**: Stereo left/right balance isolation, 3D stereo audio sweeps, subwoofer bass tone generator (20 Hz - 100 Hz), treble hearing check (5 kHz - 20 kHz), interactive tone synthesizer, and microphone noise floor/clipping tester.
- **Display & Monitor Diagnostics**: Fullscreen dead & stuck pixel detection, RGB solid color auto-cycle, color banding test, backlight bleeding test, pixel response time ghosting visualizer, and screen refresh rate / FPS estimator.
- **Gamepad & Controller Diagnostics**: Gamepad API visualization for Xbox, PlayStation & Generic controllers, analog stick drift detection, deadzone measurement, analog trigger pressure gauges, and button matrix.
- **Network Performance**: Web-based ping latency, jitter, packet loss rate, and download/upload bandwidth estimation.
- **Replacement Switches Catalog**: Database of mouse microswitches (Huano, Kailh, Omron, TTC, Razer Optical) and keyboard switches (Gateron, Wooting Lekker HE, SteelSeries OmniPoint, Cherry MX), comparing actuation force, lifespan, switch type, and hardware compatibility.

## Diagnostic Specifications & Algorithmic Parameters
- **Mouse Double-Click Chatter Threshold**: Configurable 10ms - 200ms (default 80ms). Click events occurring below this interval are flagged as mechanical switch contact bounce.
- **Keyboard Debounce & Hold Threshold**: Configurable double-click threshold (default 300ms) and target hold duration (250ms - 2000ms).
- **Audio Synthesizer**: Web Audio API oscillator nodes (Sine, Square, Sawtooth, Triangle) spanning 20 Hz to 20,000 Hz.
- **Privacy & Execution**: 100% client-side JavaScript in browser memory. No audio, video, keyboard inputs, or hardware telemetry are uploaded to external servers.
