This will probably be more useful to custom speaker builders, but coil winding has always been a bit tedious. [iwicom] put together a simple coil winder using a hand drill, a magnet, a reed switch that triggers a pedometer. Aside from the coil winder, I love the idea of using the pedometer as a cheap event counter.
