Linear induction flashlights, colloquially known as Shakelights, were popular in the early 2000’s, and their technology intrigued me. It wasn’t the most practical design, but fads don’t need to be practical. The operation was that a magnet passed through a wire coil and the moving magnetic field pushed current the wires. That’s the premise of many generators. With this simple technology in mind, a business card was created which printed the coil of wires on a PCB then a magnet would be glued on a flexible arm. When the card shakes, the heavy magnet oscillates inside the coil, and some current is generated. A thin board will be necessary for flexibility. There were only a few turns of wire in the coil so it may not be enough to power an LED. Coils were only placed on the top of the card. There was no practical application for this design; it was only for fun.
