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, the reed switch closes, powering the electromagnet, pushing the tip of the fidget spinner forward, and starting the cycle anew. Think of it as the same technology that goes into a particle accelerator or a maglev train. Or a brushless DC motor.
Haven’t gotten your daily fill of fidget spinner hacks and fidget spinner news? Don’t worry, because we got your back, fam. Check out this amazing way to teach STEAM education — the ‘A’ stands for ‘arts’ — with the help of fidget spinner shaped PCBs and a flanged bearing. Is your oscilloscope too boring? Spice it up with some fidget spinner awesomeness. Useless machines are cool, and even [Marvin Minsky], the father of Artificial Intelligence, would say this fidget spinner hack is amazing.

It’s great, if slightly ironic, to see people doing something other than fidgeting with their fidget spinners. Who would have thought a fad that began as a few extra skateboard bearings and a 3D-printed blob of plastic would beget so many truly interesting hacks?
