As a hacker community, we are no strangers to beautiful and unique musical instruments. A sympathetic nail violin built by [Nicolas Bras] is a welcome addition to the eclectic family. Working up from the simple idea of a nail in a piece of wood and adjusting the pitch by hammering the nail farther into the wood, [Nicolas] expanded the idea. With careful planning and tuning, the nails can have sympathetic properties. These properties mean that when one nail is played via a bow, it causes other nails to sound, creating harmonies and sustains.
With a bit of careful woodworking and a scant touch of metalwork, an instrument was crafted. It offers vast flexibility as it can be played by bow, by plucking with your finger, or by strumming. There are several levels of nails, each level having a paired sympathetic nail. This allows for a diverse and versatile instrument.
Here at Hackaday, we seem to have a thing for tiny violins, whether physical or virtual. While the nail violin may not look like your traditional violin, we can certainly appreciate the wonderful music it creates.

Playing the tiniest of violins may be a phrase to encapsulate the complete lack of sympathy as someone unpleasant receives their just deserts, but have any of you ever considered how such a feat might be achieved? Unless you’re an unusually talented virtuoso with the bow, it’s difficult to believe that such a small instrument could be played with ease, even if it were to be available in the first place.
Happily a solution is at hand to all those minuscule stringed instrument woes, courtesy of [Alexandra Covor], who has created a miniature PCB violin that is after a fashion playable. It may not be a conventional instrument with a horsehair bow and traditional sounding mechanism, but its electronic voice should still deliver enough to delight.
At the heart of the violin-shaped PCB is an ATtiny85 and a piezoelectric buzzer, and just where you might expect them are a set of strings made from wire attached to the PCB. The instrument can play stored tunes, but since the strings are hooked up to an analogue input on the microcontroller, it can be played as a touch instrument. Finally a pair of LEDs behind the translucent FR4-only F-holes complete the look. It’s fair to say that Itzhak Perlman and his ilk are safe from challengers bearing this instrument, but it’s still an eye-catching piece of PCB art.
This isn’t the first tiny violin that’s been featured here, some others are much smaller.
If you’ve never heard a hurdy-gurdy before, you’re in for a treat. Not many people have, since they’re instruments which are uncommon outside of some eastern European communities. Think of a violin that replaces the bow with a hand-cranked wheel, and adds some extra strings that function similar to drones on a bagpipe. The instrument has been around for hundreds of years, but now it’s been given an upgrade via the magic of MIDI.
All of these new features come from [Barnaby Walters] who builds hurdy-gurdys by hand but has recently been focusing on his MIDI interface. The interface can do pitch-shifting polyphony, which allows the instrument to make its own chords and harmonies. It also has a hybrid poly synthesizer, which plays completely different sounds, and can layer them on top of one another. It can also split the keyboard into two instruments, where the top half plays one sound and the bottom half another. It’s an interesting take on an interesting instrument, and the video is definitely worth a look.
The hurdy-gurdy isn’t a commonly used instrument for hacking compared to something like drums or the violin, of course. In fact we had to go back over ten years to find any other articles featuring the hurdy-gurdy, the Furby Gurdy. It was an appropriately named instrument.

They say the only difference between a violin and a fiddle is the way you play it. If that’s so, this modular violin will need a new name, since it can be broken apart and changed in ways that make it sound completely different, all within a few minutes.
The fiddle is the work of [David Perry] and has 3D printed body, neck, pegbox, and bridge. While it might seem useful on the surface as a way to get less expensive instruments out in the world where virtually anyone has access to them, the real interesting qualities are shown when [David] starts playing all of the different versions he’s created. The sound changes in noticeable ways depending on the style of print, type of plastic used, and many other qualities.
Of course you will need a bow, strings, pegs, and a fingerboard, but the rest is all available if you have a 3D printer around. If you’re already a skilled violinist this could be a very affordable way to experiment with new sounds. It’s not the first time we’ve seen 3D printed violins, but it is the first time we’ve seen them designed specifically to alter the way they sound rather than their physical characteristics. If you want to make your own, all of the .stl files are available on the project’s site.

[Sean Riley] is a violinist who had a problem. He wanted to play one particular piece, but he couldn’t. It wasn’t that he lacked the skill — he a doctoral student at the University of Texas and has two degrees in violin performance from The Julliard School. The problem was that “The Dharma at Big Sur” by [John Adams] is made for an instrument with six strings, while most violins only have four. So he did what any of us would do. He stopped by the local hackerspace and fabricated one. You can hear (and see) [Sean] performing with the instrument in the video, below.
The University of Texas operates “The Foundry” which is a hackerspace with all the usual items: laser cutters, 3D printers, and the like. It is open to all their students and staff. [Sean] needed some help with the engineering, and was lucky to find a mechanical engineering senior, [Daniel Goodwin], working at The Foundry.

[Martin], of the YouTube channel [WinterGatan], recently uploaded a video tour of the Phonoliszt Violina, an orchestrion, or a machine that plays music that sounds as though an orchestra is playing. The interesting thing about this one is that it plays the violin. At the time of its construction, people weren’t even certain such a thing would be possible and so when [Ludwig Hupfeld] first built one around 1910, it was considered the eighth wonder of the world.
The particular one shown in the video is at the Speelklok Museum in Utrecht, the Netherlands. The bow is a rotating cylinder with 1300 horsehairs. To get the sound of a single violin, it actually uses three of them. Rather than the bow being moved to press against the strings, the violins tilt forward to make their strings contact the rotating bow. Only one string is used per violin, hence the reason that three violins are needed. The volume is controlled by making the bow rotate faster for more volume, and slower for less. Mechanical fingers press against the strings with cork to more closely imitate the human fingertip.
The machine consists of both the mechanical violin and piano under the guidance of two paper rolls, with one roll playing at a time. See and hear it in action in the video below.

[Bithead942]’s ten-year-old niece is a huge Star Wars fan, and also a violinist. Which of course has led her to learn to play some of the music from the film franchise, and then to ask her uncle to make her violin bow light up like a lightsaber.
His solution might seem fairly straightforward at first sight, simply attach a strip of DotStar addressable LEDs to a bow and drive them from an Arduino Pro Mini to gain the required animation of a saber power-up. But of course, there’s another dimension to this project. Not only does the bow have to do its lightsaber trick, it also has to be a playable bow. The electronics must not impede the musician by being too heavy or intrusive, but the result must have enough power in reserve to keep the lights burning for the duration of a performance.
After experimentation with AAA cells and CR2032s the power requirement was satisfied by a tiny Li-po cell attached to the top of the end of the bow with industrial Velcro, and the LED strip was glued and further secured using tiny rubber bands of the type used by orthodontists.
A short demonstration of the bow’s lightsaber action is shown below the break, we’re sure it’ll impress the young violinist’s audience.
