Stringed instruments make noise from the vibrations of tuned strings, using acoustic or electronic means to amplify those vibrations to the point where they’re loud enough to hear. The strings are triggered in a variety of ways – piano strings are hit with hammers, guitar strings are plucked, while violin strings are bowed. Meanwhile, [Martin] from the band [Wintergatan] is using marbles to play a bass guitar.
[Martin] starts out with a basic setup. The bass guitar is placed on the workbench, while a piece of wood is taped to a tripod. The wood has a hole drilled through it, and marbles are dropped through the aperture in an attempt to get them to land on the string. Plastic containers are used to easily alter the angle the bass guitar sits at, relative to the bench, while an acrylic guide sits around the string to try to guide the marbles in the desired direction. These guides are important to make sure the marbles hit the top of the string, and bounce cleanly in the desired direction afterwards.
The initial setup is too inconsistent, so [Martin] places a notch in the wood and builds a lever system to hold the marbles and then release them in a controlled manner. [Martin] then checks that the system works by analysing footage of the marble drop with slow motion video.
The video covers the CAD design of an eight-slot guide so the four strings of the bass can be played more rapidly than in their previous build. Two guides per string allow each string to play two notes in quick succession without having to worry about marble collisions from playing too quickly.
It’s a great build, and we’ve seen [Wintergatan]’s work before – namely, the incredible build that was the original Marble Machine.

Remember those childhood memories of your grandmother telling you to stop hammering away at her pots and pans? Odds are pretty good that the last time you struck a beat with her dishware, you had a few more years to go before you understood tempo and rhythm. Now that we’re a bit older, [Jiffer Harriman] invites us to return to our kitchen armed not only with those childhood memories, but also a with the Kitsch-Instrument: a suite of solenoids, a controller, and a software pipeline to algorithmically turn your kitchen into a giant percussion instrument.
The Kitsch-Instrument is a modular music system that enables the user to pull a percussive pattern out of his or her everyday kitchen utensils. The percussion hits come from a series of mosfet-driven solenoids that can be fixed onto plates, cups, and other everyday items through a variety of clips. These solenoids are collectively driven by two stacked custom Arduino shields that are, in turn, driven either by hand with a button-interface, or algorithmically with a pattern generated by the graphical programming language, Pure Data.
In designing this project, [Jiffer] and his team intended to bring not just a musical tool to young tinkerers. They also aimed to help educate these young minds with multiple entry points into their project. For top-level users, adding buttons is almost as easy as plug-in-and-play. For experienced circuit designers and tinkerers, the entire project is open source with the board layout and software available for download. Overall the project can be explored from lower and lower levels while still retaining its functionality as a musical interface.
If you suspect that this project seems to have that same whimsical sense as the Auto-Meter-Reader Feeder, you’d be right! [Jiffer] and [Zack] hail from the same lab at the University of Colorado. We’re excited to see what upcoming beats will arise from a truly off-the-shelf symphony.

[Tyler] was looking for a gift for his friend’s one year old son. Searching through the shelves in the toy store, [Tyler] realized that most toys for children this age are just boxes of plastic that flash lights and make sound. Something that he should be able to make himself with relative ease. After spending a bit of time in the shop, [Tyler] came up with the Pandaphone.
The enclosure is made from a piece of 2×4 lumber. He cut that piece into three thinner pieces of wood. The top piece has two holes cut out to allow for an ultrasonic sensor to poke out. The middle piece has a cavity carved out using a band saw. This would leave room to store the electronics. The bottom piece acts as a cover to hide the insides.
The circuit uses an ATtiny85. The program watches the ultrasonic PING sensor for a change in distance. It then plays an audio tone out of a small speaker, which changes pitch based on the distance detected. The result is a pitch that is lower when your hand is close to the sensor, but higher when your hand is farther away. The case was painted with the image of a panda on the front, hence the name, “Pandaphone”. Based on the video below, it looks like the recipient is enjoying it!

You’ve most certainly heard a pedal steel guitar before, most likely in any ‘old’ country song, or more specifically, any country song that doesn’t include the word ‘truck’ in its lyrics. Pedal steels are strange devices, looking somewhat like a 10-string guitar with levers that change the pitch of individual strings. Historically, there have been some attempts to put a detuning mechanism for individual strings in normal electric guitars, but these are somewhat rare and weird. [Gr4yhound] just nailed it. He’s come up with the perfect device to emulate a pedal steel in a real guitar, and it sounds really, really good.
The imgur album for this project goes over the construction of the ServoBender in a bit more detail than the video. Basically, four servos are mounted to a metal plate below the bridge. Each servo has a spring and cam system constructed out of 3D printed parts. The detuning is controlled by an Arduino and a few sustain pedals retrofitted with hall effect sensors. Simple, really, but the effect is astonishing.
[Gra4hound]’s contraption is actually very similar to a B-Bender where a guitarist pushes on the neck to raise the pitch of the B string. This setup, though, is completely electronic, infinitely adjustable, and can be expanded to all six strings. Very, very cool, and it makes us wonder what could be done with one of those freaky robot guitars, a soldering iron, and a bit of code.
Video below, because you should watch it again.

[Imogen Heap] is well-known for performing with DIY and cobbled-together instruments, and now she’s teaming up with another famous DIY instrument musician for a world tour. That’s the cool part, now here’s the awesome part: they want to take your DIY musical instrument on tour for a scrapyard symphony.
Both [Imogen] and [Leafcutter] are semi-regular Hackaday features, with [Leafcutter] building hydrophones and [Imogen] doing some crazy stuff turning gestures into music. They’re both known for their strange and esoteric sounds that sends Rolling Stone writers scrambling for a thesaurus, and now they want your disused or discarded music machines to use live on their world tour.
The team is looking for video submissions of any musical creatures you’d like to send around the world. The only real guideline on what they’re looking for is, ‘the weirder the better’, with an apparent slight emphasis on physical machines over the purely electronic.
Video of the duo below.

While Thingiverse is filled with Ocarinas, there’s little in the way of printable instruments for more serious musicians. [David Perry] hopes to change this with the F-F-Fiddle, the mostly 3D printed full-size electric violin.
The F-F-Fiddle is an entry for the LulzBot March 3D Printing Challenge to make a functional, 3D printed musical instrument. Already there are a few very, very interesting submissions like this trombone, but [David]’s project is by far the most mechanically complex; unlike the other wind and percussion instruments found in the contest, there are a log of stresses found in a violin, and printing a smooth, curved fingerboard is quite the challenge.
While there are a few non-printed parts, namely the strings, a drill rod used as a truss rod, some awesome looking tuners, and of course the piezo pickups – the majority of this violin, including the bridge, is 3D printed. It’s an amazing piece of work, and after listening to the video (below), sounds pretty good too.
You can grab all the files on Thingiverse and read up on the build at Openfab PDX.

Way back in the 60s, strange electronic instruments were all the rage. The most famous of these made before the era of the synthesizer was the embodiment of musique concrète, the Mellotron. This instrument had an incredibly complex arrangement of magnetic tape that allowed a performer to play a keyboard and have the sound of any instrument come out of a speaker. This system was prone to failure, and there has been a lot of technological improvements in tape over the last fifty years, leading [Mike Walters] to build a new version of his famous Walkman-based Mellotron, the Melloman.
This build is an upgrade over the previous Melloman made in 2009. Like the original, this build uses 14 portable tape players, each loaded up with a continuous tape for each note. The tapes contain two octaves of the same note, one each on each channel, which are routed to the output whenever a key is pressed.
There are a few improvements over the old Melloman. Instead of transistors, [Mike] is using optocouplers to send the recorded sounds to the output. This build is also a whole lot cleaner, with the wiring looking very professional. As for a sound demo, you can check out the video below.
