In this video, I show you how to build a device that will accelerate a the popular fidget spinner to 1440 RPM or higher! It uses electromagnetic repulsion and a mosfet-reed switch trigger system to activate the magnet. The fidget spinner has magnets on each leg. It works really well and it is really cool.
