Back when electric guitars were a new thing, winding pickups was a very labor intensive and error-prone process. The number of windings could easily vary by a few hundred turns of wire, making the resulting pickup either anemic or much more powerful than the other pickups in the guitar. [Davide] is starting to wind his own pickups, and desiring a little more precision than simply guessing how many winds are on a coil he built an AVR coil winding machine.
