Shoutout to my friend [mention:a38610f314514468a980d9a30797642d:e9ed411860ed4f2ba0265705b8793d05].

He has real world experience with vibration monitoring. In the Peru mining industry.
While I'm working with a 15 Watt speaker, he works with 100s of horsepower machines that need to run reliable all day every day.

It's so good to have industry feedback on a road test, while the story is being written.

I've found a good shaker platform:

A powered subwoofer from Logitech. Small, 15 W. The speaker suspension good enough to take some ballast.
It was defect - I had to open it to resolder a loose wire. I may show some photos of the inside.

In the video, it seems that there's modulation in the movement. That's a video artifact, not happening in reality.
