A Pair of Steppers are Put to Work in This Automatic Instrument Pickup Winder

For something that’s essentially a coil of wire across some magnetic rod pieces, an electrical guitar pickup is a complex bit of technology. So much about the tone of the tool is dictated by the way the pickup is wound which controlling the twisting process is something best achieved with a system. This automated pickup winder isn’t just a high-end machine, although it’s adequate for the job in hand, and has some interesting possibilities for refinements.

First off, as [The Mixed Signal] points out, his pickups aren’t meant for use on a guitar. As we’ve noticed until , the musical endeavors he has handled are offbeat, and also this single-pole pickup is destined for some other unusual instrument. This ’s not to mention a guitar pickup couldn’t be wound with this particular device, of course, as may inductors, solenoids, or Tesla coils. The running gear is built around two NEMA-17 stepper motors, one for the coil spindle plus one for your winding carriage. The carriage runs onto a short Acme lead screw and linear bearings, then moving back and forth to end the coil more or less evenly. An Arduino topped with an CNC shield conducts the display, allowing for walk-away coil winding.

We do note the coil wire seems to bunch up in the ends of the coil form. We wonder if that could be cured by speeding up the carriage engine as it nears the end of the spool to disperse the wire spacing out a bit. The nice thing about builds such as all this really is that the ease with which modifications may be made — in the end of the afternoon, it’s just code.
