The Bounce Announce Automated Musical Instrument

This project completed as my final project for both Physical Computing and Introduction to Computational Media at ITP.

Briefly, ping pong balls roll down 4 individual tracks, and are launched at the bottom by solenoids. The solenoids are triggered rhythmically by an Arduino.

The ping pong balls bounce sequentially onto carefully placed musical instruments. On the instruments are several piezo-electric transducers that send serial data to Processing, which responds with a visualization scheme projected from above.

Here's a video documentation of the project. Enjoy!

Sneak Peak of "Bounce Announce"

This is video taken by Jason Stephens at ITP this evening. The Bounce Announce project has legs, and it's taking it's first steps toward ping-pong musical madness. Enjoy this clip.


Workshop Tour

After a feverish build session on the "Bounce Announce" project, I trashed the workshop and re-organized in the aftermath. This is probably the cleanest it's going to get for months, so I decided to document it.

The "Bounce Announce" instrument will be completed by Sunday, at which time I will post video of it in action. If you'd like to see it (and lots of other awesome projects) live, make sure to go to the ITP Winter Show.

Test Audio/Video for the "Bounce Announce" Audio Installation

I'll soon be building a sound installation consisting of several hundred (ping pong?) balls in a series of hopper assemblages. At the bottom of each hopper will be a feed tube with solenoids at the end. The solenoids will be triggered by Arduino, and pop out the ping pong balls at prescribed times.

The ping pong balls will bounce sequentially onto carefully placed musical instruments on the floor below, before finally coming to a rest in a cushioned collection area.

The Arduino will be communicating via midi on the computer, and following instructions from a pre-conceived score written specifically for the installation.

Video below is of balls bouncing onto different combinations of instruments, to give an idea of the "Bounce Announce" setup.

Below this is audio I captured from the above video, in layered form, to give an idea of the possibilities of the installation. The final product will hopefully be much wider in scope, with perhaps a dozen solenoids with corresponding instrument arrays.
