I was messing around and wanted to see how fast I could spin the platters using a very simple square wave generator and a single FET (no brushless motor driver/etc), turns out it was 25,000rpm because my power supply was limited to 20V

For the hell of it, I wanted to see how fast I could spin a object, turns out it was
3,808,800 RPM, 63,480 RPS, 1338mph, 2153kph, 24.3M G's

How about Ultimate Acceleration! 0 rpm to 3.2 million rpm in 25ms! 130,000rpm/1ms
