Have you ever listened to a song and wondered how they created the robotic-sounding vocals? There’s a huge variety of ways to do so. [scythe1005] decided to take their inspiration from rock history, creating a Game Boy powered talkbox (Japanese, Google Translate recommended for those that don’t speak the language).
Human speech is generated when vibrations from the vocal chords are shaped into intelligible sounds by the motion of the mouth, tongue, and other body parts known as “articulators”. A talkbox creates robotic speech sounds by using the articulators while replacing the vibrations from the vocal chords with alternative source.
A talkbox is a device most typically used with the electric guitar. The signal from the electric guitar is amplified and played through a speaker or transducer connected to a tube that is placed in the user’s mouth. The user then proceeds to mouth the desired words they wish to say, with the vibrations provided by the guitar’s signal instead of the vocal chords. A popular example of this is Peter Frampton’s use of the talkbox in Do You Feel Like We Do.
[scythe1005] used the same basic bones in their design, using a Game Boy to feed sound into a basic audio amplifier kit and a transducer connected to a tube. This gives a very 1980s synth sound to the vocals. It’s a simple build in concept but one we haven’t seen a whole lot of before. Using off-the-shelf modules, you could build something similar in a weekend. Also featured in the video is an ArduinoBoy — a useful way of controlling a Game Boy over MIDI. It’s used here to interface the keyboard to the handheld console. Video below the break.
As we’ve seen before, the Game Boy is an incredibly popular platform for music — chiptune artists regularly modify the device for better sound.

Brothers [Armand] and [Victor] took their acoustic guitar to the next level, making their own pickups to turn it into an electric guitar. The result is that awesome electric guitar sound.
The pickups are homemade magnetic pickups. Each string has a steel bolt behind it with three ceramic magnets on each bolt. A coil is also wrapped around all the pickups. That coil is what’s connected to the wires going to the amplifier. When a string vibrates, it changes the magnetic field in the pickup which induces a current in the coil and that is then sent on to the amplifier to be altered as desired and turned back into sound. Of course that meant the guys had to replace their nylon strings for steel ones.
With just the volume amplified the sound isn’t very different but when the amplifier’s gain is turned up and the volume turned down the sound is undoubtedly electric. As you can hear in the video below, Johnny B. Goode, Paint it Black and Satisfaction take their acoustic guitar’s sound to a whole new level.

Sheet metal. Beer cans. Pieces of chain. Not items you’ll typically find on the BOM for a custom guitar. But nobody told [Maarten van Halderen] that, and so he threw them all together into a gitaar van schroot, or scrap guitar for the Dutch impaired (YouTube link).
The video shows the build process, starting with plasma cutting and welding sheet steel for the body. The neck is fabricated from rectangular steel tube, with nails serving as frets. Overall it looks like a Les Paul, except for the sink strainer basket mounted in the sound hole and the crushed beer and soda cans tacked to the body for decoration. The chains are a nice touch too. And this doesn’t appear to be [Maarten]’s first attempt at scrapyard lutherie – toward the end of the video we see that the beer can axe joins a very steam-punk looking older brother. They’re both good-looking builds, and the video after the break proves they can sound pretty good too.

What you’re looking at above is a six-stringed mechatronic slide guitar, where each string and associated servos is assigned its own MIDI channel.
It’s a project [Jim Murphy] has been working on for a while now, and technically, it’s the second iteration — he’s calling it the Swivel 2. The original Swivel was more of a proof of concept, using bulky stepper motors and solenoids — in this one he’s upgraded to hobby style servos, using four per string. One to change the pitch, one to clamp the pitch shifter, and two to pick and dampen the strings.
He’s designed the PCB control boards himself utilizing an Arduino bootloader-equipped ATMEGA328, which takes in the MIDI signal from a computer and moves the servos accordingly — to produce the audio signals he’s been using Ableton Live to write the patterns.
The entire setup was designed in 3D CAD and is designed to be completely modular. He’s even made the guitar pickups himself using 3D printed spools, and hand wrapping the coils with copper enamel wire. Lend an ear after the break to hear it in action.

We’re not sure how we missed this one, but it definitely deserves a look. Professor of Mechtronics [Olaf Diegel’s] 3D printer must go to 12, because he’s printed these incredible electric guitar bodies. You probably won’t be making your own on your filament printer, however, because [Diegel] uses SLS (Selective Laser Sintering) to create the body out of nylon, then he dyes the resulting piece in a two-step process. You can read more about the construction specifics on his website.
And, they’re more than just eye-candy: the guitars sound brilliantly metallic. There are more than enough pictures and videos to keep you occupied on the site, where you can sift through all eight designs to your heart’s content. You’ll want to keep reading for a couple of videos embedded after the break, which feature some demonstrations of the guitar and comparisons to traditional electric guitars, as well as a brief history of its construction and build process.

After a bit of inspiration, [Pete] decided to build a solid body electric guitar for himself. Instead of assembling a conglomeration of off-the-shelf parts, he plans on building just about everything from scratch. This includes the guitar pickups, so he built himself a pickup winder that has measures RPM, ETA until done, and auto stop for when the pickup is complete.
Electric guitar pickups are simple devices – just a magnet for each string wrapped in thousands of turns of wire about as thin as a human hair. [Pete] began his build with a cheap sewing machine and added a tachometer and pickup mount. As an added bonus, [Pete] threw in an ohmmeter to measure the coil resistance and a Gauss meter to measure the magnetic flux and polarity of the pole pieces. It’s a very nice build that’s designed to be as functional as commercial pickup winders.
[Pete] was originally inspired to build a pickup winder by the Les Paul Google doodle, and he plans on continuing Les Paul’s tradition of guitar innovation by building his own solid body guitar. The wood has been cut already, and we can’t wait to see the final product.
Check out a video of [Pete]’s coil winder in action after the break.
