Offline vibration probe diagnoses failing motors and can cut power before breakdown

Project Pulse is a magnetic vibration and sound sensor that attaches to small motors such as fans, pumps, and compressors. In about 30 seconds it reports the ISO severity zone and the likely fault, such as imbalance, looseness, overload, or bearing wear, in plain language. When paired with an optional stop plug, a Guard mode learns each motor's normal pattern, watches for drift, and can cut power if needed. It targets independent repair technicians and small workshops that cannot justify expensive commercial analyzers or subscriptions. All processing runs locally on the device, and an open-weight Gemma 3 1B model writes readable reports, with every figure checked against measured values before display.
