Three Magnets Make Fidget Spinners Amazing And Only Engineers Will Appreciate This Hack!
The fidget spinner posts will continue until morale improves. This time, we’re looking at [TannerTech]’s electromagnetic accelerator for a fidget spinner. [Tanner] can spin his fidget spinner electronically using parts he had sitting around and a clever application of magnets and relays! Engineers hate him!
[Tanner]’s build consists of three magnets mounted on the tip of a fidget spinner’s arms, with the North pole facing outwards. The ‘drive circuit’ consists of an electromagnet — an inductor [Tanner] found in an old TV set — a reed switch, and a MOSFET. When the circuit is placed next to the fidget spinner, …read more
