16 Channel Amp building pix

This is an amp I built will be used for the "audio hallway" installation of The (unfinished) Ballad.... It has 16 independent audio channels going to 16 little speakers hanging in a hallway. This amp (which has an attached 5V power source not seen here and can be expanded to 24 or even 32 channels!) will hopefully serve as a good project amp for use in installations or other applications in which control over a large group of discreet audio channels is needed (extreme spatialization!).   Special thanks to Charlie Vickers at the Joint Engineering Physics Instrument Shop for helping me bend and cut the metal for the amp housing.

(unfinished) Ballad...In-Progress Demo Show Scheduled for May 18th

I've scheduled an in-progress/demo presentation for The (unfinished) Ballad of Adam and Elena Emery.
It will be:

Friday, May 18th, 4-7pm
Mathewson St. Methodist Church
134 Mathewson Street Providence, RI
(between Westminster and Washington sts)

It will be on the 4th floor in an amazing children's blackbox theater, put in by a now extinct theater group.  I'll be using a number of rooms and the presentation will be mostly a tech demo of the moving curtains, multi-little speaker hallway, and the 3-screen Sgt. Zarrella/Rescue dog installation.  I will have some audio/video content in these installations, but the main goal is to make sure these "instruments" work and see how they sit with each other in different rooms.  All comments/criticisms/responses are welcome.

The presentation will be informal and on-going 4-7pm, so come when you can!

(unfinished) Ballad...Curtain/Motor Demo Video May1st

So I settled on servo motors instead of steppers.  They are lighter, cheaper (I have a bunch from a previous piece anyway), robust, and easy to wire (no driver chips needed, just ground, power and pwm control signal) and stronger than they look.  They don't turn more than 180degress, but it doesn't seem to matter yet.  I had trouble getting the steppers to work with their drivers being controlled by the Arduino.  Although I didn't give it a true "college try"-- the other drawbacks (weight, cost, complexity) was more important to my decision.   In this demo I've set up a Wii-remote to control their position.  This will be a tool used by a performer (mezzo-soprano, singing a solo, channeling Elena Emery).  When the "curtain room" is not in use by performers, it will be a installation, controlled by sensors (passive infrared and or ultrasonic pulse) monitoring  audience members and randomly reorienting while it plays back the audio/video content.
