Pickups are a key part of an electric guitar’s sound. You can spend a king’s ransom on tracking down just the right Vintage American Original 1950s Whatevers (TM) to put in your Spudocaster, but it’s not the only way. [Keith Decent] decided to make a pickup from scratch, using only materials found lying around the workshop. (Youtube, embedded below).
To build a pickup, you’ll want some magnet wire. In this case, [Keith] harvests this from an old transformer. A pickup body is then constructed from an old wooden ruler and some machine screws. A drill is used to spin the pickup body while the wire is roughly wound on, and everything is then held together with lashings of hot glue.
It’s a grungy build with a very Mad Max vibe – with the perfect aesthetic to suit [Keith]’s junkbox guitar build. The sound is good, but difficult to rate accurately when used on a guitar with slightly imperfect intonation. We’d love to hear it installed on a well-tuned body to get a better comparison.
It goes to show you don’t need to spend money on new parts and tools to get a build started. Sometimes you can make something perfectly functional with stuff you have lying around at home. Video after the break.

Hackaday continues to embrace our implacable spinning overlords-of-the-heart.
[zazzazzero] posted a YouTube video showing him fidgeting one of those spinners that had been hooked up to a bass guitar pickup. It makes a rather awesome rumbling sound as the pickup registers the bearings rolling around, and when hooked up to a Digidelay effects pedal he moved it beyond the rumble to more of an industrial growl like a factory hum. He also got interesting sounds by tapping on the spinner with a screwdriver.
Then he switched up to using an iPad audio app called Shaper to modify the resulting sound far beyond what he had before, with more effects options available at the touch of a button. All of these sounds can be modulated into the analog synthesizer chain, making this spinner a for-reals musical instrument.
We’ve published more than a couple pieces on music hacking, including this ASDR envelope generator project and the Atom Smasher guitar pedal.

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.
The machine uses a DC gear motor running at 1200 RPM. A magnet is glued onto the motor shaft, and a hall effect sensor connected to an ATMega8 keeps track of how many windings are on the coil.
The interface is simple, using character LCD to display a wind counter, motor direction, and current motor speed. There are some useful features in this machine; slow start-up and automatic stop makes winding pickups much easier than the traditional home method of winding pickups with a sewing machine.

[Valve Child] has been building a few three-string cigar box guitars. Of course he’ll need a few pickups, but three-string guitar pickups aren’t exactly easy to come by. To solve this problem, he’s built a guitar pickup winder powered by a steam engine.
The pickup winder is powered by a Wilesco D20 model steam engine, connected to the actual winding mechanism via a rubber belt. To the right of the bobbin bracket is a mechanism built out of Meccano – Erector sets for us americans – that provides a mechanical counter for the number of wire turns and a wire traverse to keep each layer of wire somewhat even across the width of the bobbin.
Previously, we’ve seen [Valve Child]’s really sweet sounding lap steel build from a log using a hand-wound pickup and a preamp tube as the bridge. It’s questionable if the guitar signal came from this lap steel via the pickup or the microphonic tube, but now [Valve Child] has a really, really good method of improving his pickup production abilities.

Yep, that’s a picture of a Laptop rocking out on an electric guitar. In what can only be described as a truly bizarre hack [CNLohr] discovered that the RF noise from the computer can be used to play music through the guitar’s pickup.
Check out the clip after the break to hear an annoying, but very discernible rendition of Jingle Bells. Once [CNLohr] stumbled onto the fact that changes in what the graphic processing unit is doing was affecting the pitch detected by the pickup he started writing some code. Now he’s got a program that automatically calculates the size of the window, and produces a white square on a black background to dial in the GPU at the right frequencies.
He mentions in the notes accompanying his video that he had to turn off Vsync to get this to work right. We don’t understand why but we’d love to hear what you think in the comments.

We didn’t believe this hack at all when we saw it, or rather heard it. Surly a guitar made out of a shovel couldn’t sound decent. But the video (after the jump, skip to 2:40 for the jam) to our untrained ears sounded pretty rad. Could be the supremely well done wood work, proper use of tools, high tech pickups, or maybe Russian magic, we don’t know.
In fact, if you continue the video it doesn’t stop there. The creators also made a 2 string bass and a few other instruments from shovels. Do I smell a new shovel hero?

[Robert Pickering] shares his automated guitar pickup winder with us. He built it for his senior project at Old Dominion University. Two stepper motors are used to wind the magnet wire around the pickup hardware. The unit is PIC based and about six minutes into the video (embedded after the break) you can see that he used wire wrapping for this build. Curious, one of the comments on our latest Hackaday Links mentioned that wire wrapping was rarely used anymore, but here it is anyway.
We especially like the limiting switches he’s using on the traverse mechanism. There are momentary push buttons on either side of a carriage which are depressed when a drywall screw in the sides of that carriage hits them. This makes for very easy calibration because the screw can be raised or lowered with just a bit of screwdriver work. Well built and documented, we’re sure he’ll get some high marks on this one.
