### Brief 1. Tamarillo. Music Mathematics

A project done by Danny & Mirela of tracing parabolic speakers was an interesting investigation of sound and applied mathematics.

Since we’re also doing another project that’s related to parabolic speakers, we figured let’s do this one together - and simultaneously work on the Harmonograph-project too, see pictures below for the book I showed in class.
In the first project we’ll make parabolic speakers (probably 2) that ‘follow’ the people walking around in the installation. So, beams of audio will be directed to the person, and he/she will hear it while other people (not standing in the beam) hear much less - if anything.
In the Touch Harmonographs project, we’ll try to make an ‘environment’ where people can create harmonographs on the walls (floor?) by drawing a line with their fingers/hand. A corresponding sound will be created.
Week 1. Try to make some harmonograph graphics (hooked to mouse dragged). Upload a screen-capture.
Week 2. Make some sounds correspond with the graphics. (Octave, Chords, see harmonograph booklet). Finish watching Theo’s VideoManager Class Tutorial & start writing classes ourselves.
Week 3. Begin making tools for a touchscreen (Ir camera, Ir lights, surface?). Decide whether to let the walls be as they are - or to put something there to deform the projections. Reserve a beamer (Rental)!
Christmas break?
Week 4. Finishing up the code - testing & trying to make it crash, etc. etc.
Week 5. Making the complete test setup. Fix last problems that occur.
Week 6. Complete project.
And a video: Harmonograph tryouts in O_F - screencapture

Tracking Parabolic Speakers:
week 1 - Looking up examples of parabolic speakers - tutorials maybe? First dish tests (speaker + dish & one speaker in tube - picture + video coming soon!)
week 2 - See how to make the arduino + 2 servo’s work with O_F. How to make 2 arduino’s work at the same time? Look for steppermotor-chips. Post more stuff on the blog - pictures/video/progress.
week 3 - Start writing code for face/blob/? -detection - how to track people the most efficient way, etc.
Christmas break?
week 4 - Make first test-setting - complete writing the code & assembling servo’s + arduino(’s). Final decision which audio to use.
week 5 - Finishing up - testing.
week 6 - Complete project
