Coil winder Part 2: considering servos for traverse

In order to minimize parts count, cost, and complexity while maximizing flexibility, I have settled on a servo for the winder’s traverse mechanism, rather than the traditional stepper or DC motor. It will I weighed the pros and cons, and

Working toward a 3d-printed CNC coil winder

My recent excursions into the world of Arduino and 3D printing has opened up a whole world of possibilities.  Since I am in the process of retooling my workshop and designing a new winder, I thought it would be a

3D printing Pickup Bobbins

Hello world. It’s been a while.  I have been busy with various projects, the holidays, etc, BUT here is a doozy: 3D printing guitar/bass pickup bobbins.  The standard bobbins that are available are good, cheap, and easy to find, but

Guitar Pickup Theory #7: Effect of pickup cover material on tone and noise

So here is the blog about pickup covers that I promised in the backplate post from a while back. I touched on the concepts of eddy currents and capacitance in that post, but I will go into a bit more

Guitar Pickup Theory #6c: Coil shape Part 3 – coil-sense area

Welcome to part 3. Let us again recap the theories we are testing: theory 1) (mostly true) – the shape gives more inductance and DCR per turn, which makes for a lower resonant frequency with a lower Q value theory

Guitar Pickup Theory #6a: Coil shape Part 1 – DCR and inductance

This entry will examine the effect of the shape of a pickup coil on the tone of the pickup, as well as the underlying causes, and provide empirical evidence as support. More specifically, I want to address tall+narrow coils vs
