goofys a dog and plutos a dog but goofy can talk whaaa

[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.

Block Noise, Listen To Music

May 4, 2014 by Rich Bremer 37 Comments

Noise Blocking headphones made from industrial earmuffs

Noise-Cancelling Headphones actively cancel external sounds so the listener can hear their media without distraction. They do this by taking external sound waves from an on-board microphone, inverting the audio signal and mixing that with the media audio. The outside sounds and their inverses cancel each other out before reaching the listener’s ears. There is one downside to these types of noise-cancelling headphones, they are very expensive.

[Mike] works in a wood shop and didn’t want to pony up the hundreds of dollars it would cost for a pair of noise-cancelling headphones, let alone having such an expensive electronic device in a dusty workshop. The solution? Make some headphones that will block out the noise but still allow the comfortable listening of music. This project is simple but effective; inexpensive headphones taken apart and installed in a pair of Industrial Ear Muffs. If you’d like to make your own, [Mike] gives step by step on the above link.

Restoring A Violin With 3D Printed Parts

May 4, 2014 by Adam Fabio 33 Comments

Every family has an heirloom. It might be a watch, a book, or a stuffed pet. [Mike’s] family heirloom was an antique violin. Well, not an entire violin. This particular violin consisted of a detached neck, a body, and one tuning peg. As far as [Mike] knows, no living member of his family has heard it played. [Mike] decided to restore it to playable condition.

[Mike’s] violin had been brought over to America when his family emigrated from France. The primary reason it has been saved is because it bears the name Stradivarius. Stradivarius copies and tributes are plentiful in the wild. Many of the copies are now antiques and good playing instruments in their own right, though not nearly as revered as the real thing. [Mike’s] first step was to determine if his violin was a real Strad, or a copy. Luckily he was able to get in touch with the caretaker of a real Strad in Milwaukee. It turns out that the label on his violin marks it as a copy. According to the caretaker, genuine Stradivarius instruments were signed directly on the wood. The caretaker was further able to identify that [Mike’s] violin was about 100 years old, and a relatively cheap model for the time.

While it wasn’t a real Stradivarius, the violin was still an important part of [Mike’s] family history, and deserved to be played again. Rather than re-create the missing parts to perfectly match the originals, [Mike] decided to use the resources of the Milwaukee Makerspace to create 3D printed parts.

Similar violin parts were scanned at the Makerspace. The final .stl files were sent to Shapeways for printing. [Mike] sent all the parts to a luthier for final fitting and assembly. [Mike’s] family heirloom is no longer an item to be hidden away, but a living breathing instrument for a new generation to enjoy.

NES Cartridge Hack Makes Great Novelty Gift

NES cartridge with arduino

Most all of us recall the Blinking Screen of Death on original NES systems. This was caused by a bad connection between the cartridge and the NES cartridge connector. For whatever reason, it became a very popular idea to give a quick blow down the cartridge, even though this didn’t really help. [Dale] decided to play on this annoying problem by making the NES Blow Cart!

Inspired by a previous cartridge hack, [Dale] mounted a custom made circuit sporting the ever popular ATtiny85 in a Super Mario / Duck Hunt cartridge. A small microphone sits where the original cartridge connector was, along with the on/off switch and program header. A quick blow triggers the ATtiny85 to play a song.

The most difficult part for [Dale] was to figure out how to get the ATtiny to play “music”. This was solved with the discovery of a library called Rtttl. This allowed him to take old Nokia Super Mario and Zelda ringtones and get them on the Attiny85. All files, including the rtttl library are available on his github. Be sure to stick around after the break for a video of the project in action.

Interactive Gloves Turn Gestures Into Music

Imogen Heap wearing her Mi.Mu gloves

[Imogen Heap] is a UK-based musician who is trying to change the way we think about making music. She’s been working on a pair of gloves called the Mi.Mu, and they’re getting close to production.

In the included interview she explains that while computers and technology have brought many new advances to music, twiddling dials and pushing random buttons “is not very exciting for me, or the audience”. With these gloves, the artist becomes one with the music and interaction.

The current iteration of gloves use flex sensors along each finger to determine the movement (along with motion sensors for other gestures). She’s been through many designs and hopes to integrate e-materials into the next — using the actual glove as the sensor (not physical flex sensors).

She’s been working with both developers and musicians mapping the various motions of the gloves to music which makes sense in an intuitive way, and it’s very unique to see in action.

Kyub MIDI Keyboard Puts A Piano In Your Pocket

April 16, 2014 by Kristina Panos 13 Comments

[Keith Baxter] loves making electronic instruments. His latest vision has come to life as Kyub, an open-source MIDI keyboard. [Keith] has previously graced our site and cracked Popular Science with his servoelectric guitar.

[Keith] wanted to make a completely open source instrument that’s elegant, useful, and a bit more accessible than the servoelectric guitar, so he teamed up with a hacker/electronic music expert and an industrial designer. He built the early prototypes around an Arduino Uno. The current iteration uses a Teensy 2.0 and is available in various forms through Kickstarter. [Keith] opened the Kyub up to crowd funding in an effort to obtain volume pricing on some of the parts as well as an Eagle license to make the PCB files available commercially.

The Kyub has eleven pressure-sensitive capacitive keypads on five sides of the cube. The accelerometer can be used to vary note volume, bend the pitch, or whatever else you program it to do. Of course, you’ll need a computer with a synthesizer program, but [Keith] says it is compatible with most software synth programs, some of which are free.

There’s a demo video of an early prototype after the break. Videos of the Kyub in its current form are available on the Kickstarter page.

Frozen Instruments Played At Swedish Music Festival

April 15, 2014 by James Hobson 12 Comments

[Tim Linhart] wanted to do something different for this Swedish music festival — so he decided to carve all the instruments by hand, out of ice.

The festival consists of seven bands playing very different musical styles, with over 40 concerts occurring during the festival. [Tim Linhart] has painstakingly carved each instrument from violins to cellos out of individual sheets of ice. He adds strings and fret-boards to complete each piece, and if the temperature goes above zero it’s game over. The concerts are held in a building made of ice to make sure this doesn’t happen.

And since they are built out of layers — he’s also thrown in some RGB LEDs to give the instruments a bit more pizzazz. They actually sound pretty good too!
