The $240 spindle retrofit

An edge-ML anomaly bench on a twenty-year-old spindle motor — exact BOM, exact data pipeline, exact failure modes.

Last week's scorecard ranked Edge Impulse on the Arduino Opta the highest-floor pilot in the AI-on-the-PLC category. This week the bench. Total BOM $238.94, two days of data capture, three failure-mode labels, GMM model running 23 ms inference. What worked, what didn't, and the four mistakes that nearly killed the pilot.
