GeoMag is a magnetic toy construction system. It connects together using short magnetic rods and little steel balls. Niels Kaagaard noticed the resemblance of the GeoMag rods to the pole pieces in a single coil pickup and proceeded to make a pickup out of them. When you remove the plastic coating from the GeoMag rod you can see it is a steel bar with neodymium magnets at either end. To work as a pickup pole you need to remove one of these magnets. Niels then made some bobbins from fibreboard and wound the pickup coil around the GeoMag rods using his own hand winder.
Transferring wire from the reel to the bobbins requires the coordination of rotational and translational motions, The layer winding movements are performed through either coil rotation (spindle winding) or wire rotation (fly winding).
Spindle winding In spindle winding, the bobbin is rotated as the wire passes over or through a wire guide that traverses back and forth in the direction of the axis of rotation.
This is a clever DIY pickup winder design by Niels Kaagaard. It uses a fishing reel to spin the bobbin. It is hand powered, so carbon emissions are limited to your exhaled breath as you wind it furiously.
It's missing a traverse mechanism at the moment, however, you can see that the wire is not layed down evenly. I would run a belt from the reel to power a cam traversing mechanism.
Traditional guitar pickups used alnico magnets or ceramic magnets. Neodymium magnets, a form of rare-earth magnet, have not often been used in guitar pickups. These extra strong magnets are becoming more and more available, and this instructable shows how to use them in a single coil pickup. The design uses screws as pole-pieces with small circular neodymium magnets underneath the pickups. Also contains a bit on how to pot the pickup in wax.
Joe Hoffman made this clock in the shape of a single coil stratocaster pickup . Six nixie vacuum tubes display the time, where the pickup's magnets would be.
The top and bottom of the pickup-clock were cut out of stainless steel by the Big Blue Saw Company. You send them a design and they will cut it out using their CNC waterjet and send it back to you.
The anti-backlash nuts are an adjustable pair of nuts that transfer the rotation of the leadscrew into the linear motion of the axes. The two screws allow you to adjust the tension between the two nuts to eliminate backlash (the wobble that results from wear in the nut or leadscrew).
Ever fancied making your own guitar or bass pickup? All you need is a spool of thin insulated copper wire (around 42 gauge) two popsicle sticks, some neodymium magnets (2 for each string) and some Gorilla Glue. When you have finished it you will need to dip it in melted wax.
The GraphTech brand was founded by Dave Dunwoodie. As a guitarist Dunwoodie was troubled by string binding on traditional guitar nuts.
"I went to do my first big “wang” and went totally out of tune" Dave says. "I couldn't use the guitar for stage work at all".
Dave began experimenting with a variety of composite guitar nuts designed to eliminate string binding before engineering the world’s first self-lubricating nut, a formula that is 500% slipperier than graphite.
