Hurdy-Gurdy Gets Modernized With MIDI Upgrades

October 25, 2018 by 17 Comments

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.

Thanks to [baldpower] for the tip!

Hackaday Links: August 6th, 2017

August 6, 2017 by 12 Comments

We get a lot of Kickstarter pitches in our email, but this one is different. First of all, it’s over. No biggie there. Secondly, it’s a laser-cut hurdy gurdy. What’s a hurdy gurdy? It’s a musical instrument that uses a wheel to vibrate strings. It has drone strings and a rudimentary keyboard for the melody. Think of it as ‘string bagpipes’ and you’re not that far off. This means you can laser cut (or 3D print, someone get on it) a hurdy gurdy, and that’s just awesome.

I wrote the previous paragraph without referencing Donovan. You’re welcome, Internet.

[Spencer] found a few very small seven-segment flip display units. This, of course, meant he had to build a clock. Right now [Spencer] is in the PCB design stage of the project, with the hope of finishing it before school starts. There is still an open question here: where do you get really tiny flip segment displays?

Perhaps we’ve said too much about the number one badge at this year’s DEF CON, but this is really the project that just keeps giving. [Hyr0n] thought it would be a great idea to have a shirt printed with the design of this year’s official Hackaday DEF CON badge. This seemed simple enough — all he needed to do was send the design off to a custom printed t-shirt place on the Internet and wait a week or two. This is where things got a little nuts. [Hyr0n] stole my intellectual property. My very intellectual property. Here’s a great tip for when a t-shirt place puts your order on hold because of a copyright: just say it’s creative commons, they’ll send it right on through.

The DIY-VT100 is a miniature VT100 (and VT102) terminal, because sometimes you need a standalone serial terminal. Soon, it’s going to be a Crowd Supply campaign. Who’s going to be the first to 3D print a look-alike VT100 enclosure for this little thing? Where can you get pre-bromiated filament?

We all know what the Atari 2600 is, but what is the Atari 2700? It’s an exceptionally rare prototype that used wireless controllers. One was found in a thrift store recently. [L064N] bought it for $30, and sold it on eBay for $3000.

Here’s a weird thing [Yann] sent in. The Rise mP6 was a non-Intel, non-AMD, non-Cyrix, non-VIA, x86 compatible CPU sold in the late 90s.  What’s cool about it? Three parallel MMX instructions, and an easter egg hidden in the microcode. The principal engineer on the project, [Chris Norrie], decided he wanted to hide his name in the CPU, and managed to do it without anyone else catching on. If you put ‘NZ’ into eAX and execute CPUID, it returns “* Chris Norrie *”. That’s a hack, and it’s amazing.

Da Vinci’s Viola Organista

hurdy gurdy

Leonardo Da Vinci had many unfinished projects, not unlike many hackers here. Lucky for us though, he was a bit better at writing down his ideas than we are. This is his Viola Organista, as recreated by [Slawomir Zubrzycki] — a mechanical work of art, that sounds good too!

If you’re familiar with a Hurdy gurdy, this is basically the same thing — but on a much bigger scale. It is the combination of an organ, a harp, and a viola. Instead of a hammer hitting the 61 steel-strings, spinning wheels of horse-hair (similar to a bow) caress each string via input from the keyboard and the pedal powered crankshaft. The result is a very unique sound, which is reminiscent to each of the instruments it combines.

The designs for the instrument were found in Da Vinci’s Codex Atlanticus, a 12-volume collection of many of his manuscripts and designs, documenting everything from his flying machines to weaponry. [Slawomir] spent three years and over 5000 hours perfecting his version of it.

Stick around after the break to hear it in action! Don’t forget to turn on the subtitles though, unless you’re fluent in Polish!

Furbies Transformed Into A Furby Gurdy

August 23, 2008 by 5 Comments


[David Crammer] must really like nightmares. The hurdy gurdy is a stringed musical instrument, dating as far back as the eleventh century A.D., where the strings are sounded via a rosined wheel that is turned with a crank. [Crammer] took this unique instrument, applied his circuit-bending and Furby-scalping skills to generate a Furby Gurdy that sound like Kraftwerk on acid.
