Our Two Core Engineering Divisions

• 1. Client-Side Browser Hardware Test Bench (/test/): Uses native W3C Web APIs (Gamepad API, WebAudio API, high-frequency PointerEvents, and requestAnimationFrame Canvas) to measure controller stick drift, microswitch bounce (<80ms), OLED 5% gray uniformity, refresh rate frame pacing, and mechanical keyboard switch chatter with zero software downloads and 100% local privacy.
• 2. OEM Error Code & Blink-Pattern Diagnostic Lab (/appliances/, /hvac/, /codes/, /obd2/): Translates cryptic manufacturer fault codes, LED blink sequences, and SAE OBD-II trouble codes into interactive Yes/No symptom decision trees, hidden factory test mode sequences, annotated schematics, and verified OEM replacement part numbers.
