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.

AI at the PLC — what ships, what doesn't
Five AI-on-the-PLC products, graded honestly against production.
Eighteen months after the first Industrial Copilot previews, five real products are in the field. Siemens Engineering Copilot TIA (B+), Rockwell FactoryTalk Design Studio Copilot (Incomplete), Siemens TM NPU (A-), Edge Impulse + Arduino Opta (A), Beckhoff TwinCAT CoAgent (B). A scorecard, three pre-pilot tests, and the edge retrofit I would install Monday.
