Draw MIDI: A DIY Paper Circuit Project

Update: Alex won first place in NYU Music Technology’s 2014 product design competition!                       Congrats!

 

Today’s Project: Draw MIDI

(Production: Ronny Mraz, Adam November, and Kathleen “Ying-Ying” Zhang, full credits at Youtube)

A digital-based project, Alex Haff’s Draw MIDI uses capacitance sensing to collect electrical signal from a pencil-and-paper keyboard, converts that to MIDI using an Arduino, and then sends the code into your computer via a Max patch. That may sound complicated, but it’s quite simple once you understand the function of each part of the project.

System Requirements and Code

While this project can technically be done on Windows, it takes a bit of finagling. We recommend Mac OSX.

Because Draw MIDI is a digital project, you’ll also need some code. For this project, Alex used both an Arduino sketch and a Max patch. You can find each of them here and here.

The Arduino code will run in the controller’s software on your computer. The Max patch will need to be run in Max. If you don’t own Max, never fear. You can copy and paste the code into Max’s free runtime application.

Step-by-Step

NYU Music Technology is an active member of the Instructables.com community. As such, a step-by-step guide of building the project may be found here.

Edit: Thanks for the feature, Instructables!

We had a lot of fun with this week’s project and hope you will, too! A special thanks to Langdon Crawford for cleaning up and hosting the code.

Draw MIDIPaper Circuits

Paper circuits have been making their way around the tech world because their low-cost components give them great potential for cheap mass production. For DIY, they offer similar affordability, a great availability of materials, and they’re just plain fun. There’s a novelty in creating something interactive from ink and graphite. Usually, our words and drawings can’t fly off the page, but with the addition of electronics they can light up or be heard.

For an industry application of paper circuits, watch our talk with educator Alex Ruthmann.

For some inspiration, check out this Ted Talk, “DJ Decks Made of Paper” by Kate Stone.

And for some great, simple projects the Exploratorium’s Tinkering Studio has you covered.

Home Foley Experiment: Fight Scene

Video

Happy Thanksgiving from Science of Music!

We’ve got a new video project this week. Add some literal “punch” to your fight scenes by stealing some celery from the stuffing. Tell Mom it’s for SCIENCE. Or for ART? Whichever one will get you out of trouble with your relatives.

Foley is the art of adding sounds to a film to match the footage shown on screen. You’d be surprised to know that much of the sound you hear in movies is added in after the fact. In this video, we experimented with a simple fight scene you could recreate at home. There are also other sounds that you can create with celery: monster chomps and footsteps are a couple more examples. Create your own and let us know how you did it!

A New Project: DIY Electric Slide Guitar

Video

Our compatriots never cease to amaze us.

Student and guitar pro Adam November guests on this episode of the Science of Music to show us all his homemade electric slide guitar! This DIY project was made for an acoustics class at NYU’s music technology program. Watch as Adam shows off his creation and explains how you can make your own guitar from materials easily purchased at your local hardware store.

The Science of Music Gets Its Own YouTube Channel!

Video

Hello Blogosphere!

These are your friendly music-to-science emissaries from NYU MARL announcing a new YouTube channel specifically for the Science of Music!

In this video we outline our ongoing mission is to bridge the world of music to engineering, science, and technology. And we also give you a preview for what’s to come, so tune in for a weekly demonstration or explanation from New York University’s Music and Audio Research Laboratory!

DIY: Build Your Own Microphone!

This how-to video explains the process of building a dynamic microphone (which, incidentally, can also be used as a loud speaker) from a cup! This rudimentary audio transducer could be used as a quick project for a physics class exploring electromagnetism or an audio technology class exploring transduction. Or you could do it just for kicks.

The fidelity of the completed project is not studio quality (if it was our lives would be a whole lot cheaper), but it’s cool. And on the upside you don’t have to have an EE degree to build it.
