During August 3-7, 2009, Robin Mandel and I taught a week-long intensive workshop on physical computing at Anderson Ranch. The workshop was titled Physical to Digital (see Anderson’s flier).
I created a course blog that includes arduino code, references for working with kinetics as well as videos of the students final projects.

I will spend Oct. 3 to 16 in Ghent, Belgium, participating in the 2008 Almost Cinema Festival. The plan is to show two sculptural works, and give a with my man David Bithell.
I’ve been working on some software and electronics for Robin Mandel in order to realize his Storm. First I made a Arduino-MIDI-output-translator application that converted MIDI out of GarangeBand to on and offs on the Arduino’s Digital Outputs. Then I integrated the MIDI playback into the translator application.
But ultimately, best if the Arduino simply did it all, this way the Storm installation can run without a computer. The latest implementation does just that: first you translate the midi-file to a text format; then you load it on the the arduino as a part of a sketch; the sketch also integrates a potentiometer for setting the threshold of the light-sensor, and an LEd on pin 13 that gives visual feed-back about passing the threshold.
There are a couple of ingredients:
-A Stand-alone application that converts MIDI to a peculiar text file format. Get it here.
-An Arduino Sketch that takes care of the playback from the score, as well as the triggering using a light-sensor. Get that here.
Here’s a video:
and here’s the circuit, close up.
ArduinoBt, talking to Max/MSP, using SimpleMessageingSystem.
Had many many troubles with this “programmer not responding” bull shit, but got it going eventually… still doesn’t exactly stay up for hours.
(i.e. get in touch if you’re one of the other brave few trying it!)
Demonstration of a little stand alone application for translating MIDI to an Arduino‘s digital outputs.
The editable MaxMSP patch (and many more things) are a part of aLib. You will find the patch in the “for controllers” folder, within the “Arduino” section.
This application uses
–SimpleMessageSystem library for the Arduino platform.
–Cycling 74’s MaxMSP.
–Arduino USB drivers
-RetroWare’s MidiO plugin to allow GarageBand to send MIDI to other apps.
Many thanks to Nick Mariette for his help…
I’m teaching a course along with Professor Doug Geers from the School of Music, on the topic of treating time. The course is titled Interdisciplinary Media Collaborations: Treating Time and here is the course description.
