Do You Need a Sound Detector?

Here’s a nice option for art installations and sound projects that need to detect sound and/or measure sound amplitude.

The SparkFun Sound Detector is a small and relatively easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneous and independent, so you can use as many or as few as you want at once.

This first demo that includes and arduino and the sound detector board, starts with simple “claps” in order to demonstrate the binary indication of sound. Note that that the LED changes color and an indication light goes on and off on the sound detector board.

The next demo uses a horn sound, the horn sound is more complex and an anolog representation of the sound is shown through the changing colors of the idea. As the amplitude of the sound changes so does the color.

The third demo creates feedback using the sound detectors audio out and generating feedback with the use of the mini amp.

Prototyping for Sound: Arduino MP3 Player Shield

I’m experimenting with a Sparkfun mp3 player shield for Arduino, using it to prototype for a sound installation idea. In this prototype there are just simple push buttons, while the final installation is more likely to use sensing or more complex triggers. This prototype allows me to experiment with different sounds and on a small scale, get a sense of how sound transitions might work. For the speaker I’m using my old faithful Fender mini amp, love this little device! I use it routinely for prototyping. The video here demonstrates a setup of simple push button that trigger custom sounds stored on the sd card.

There are tutorials and libraries on the Sparkfun site and Github. I used this tutorial to get started.

Connectivity Lab Live at Malmö University, Sweden

In December 2012 IBM Chief Scientist John Cohn and I participated remotely in Connectivity Lab Live at Malmö University in Sweden. It was a great opportunity to introduce Vermont Makers, swap stories about the maker movement and share our explorations arts, science and technology. To learn more see the links and video documentation below.

This week’s Seven Days features the article “Meet Your Makers: Vermont hackers, artists and inventors are sharing ideas — and solving problems.” We were thrilled to be interviewed and are very grateful to Megan James for her excellent writing and to Matt Thorsen for the creative photography.

SunTracker 2012: A New Sound Installation in Progress

Sound installation: Sun TrackerI’m currently working on a new installation “Sun Tracker” that will debut on Friday, June 22, 2012 as part of the Woodstock Digital Media Festival. Working with Jeff Branson of Denver, CO and Sam Stelfox of Burlington, a sound installation will be programmed based on the Earth/Sun relationship during the time of the summer solstice. We are using Cosm (previously known as Pachube) to keep track of the live feeds (from Colorado, Vermont and possibly California).

I met Jeff and Sam through Vermont Makers, and it’s been great to work with them. Jeff works with SparkFun out in Denver and Sam is a part of Lab B in Burlington. Along with Studio Ju Ju, Lab B has  served as a workspace for this project, in fact we met there last week with Jeff (via google+ hangout).

I’ll document the project here as we move forward. In the meantime here’s a link to more Studio Ju Ju sound installations.
