Non-Contact Diagnostics for Audio Builders, PC Modders & Mechanics
Safe Inspection Around Spinning Fans, Belts & Pulleys
Touching spinning cooling fans, alternator pulleys, or hot exhaust shields by hand to hunt a rattle is risky. Filming from three feet away reveals wobbling bearings and loose brackets with zero physical contact.
Avoid LED Shop-Light Flicker
Use natural daylight or steady DC flashlights when filming—cheap AC fluorescent bulbs flicker rapidly and can look like false brightness pulses under heavy magnification.
