3/14/01 COMTOUCH meeting notes
At this meeting, we reviewed 2 prototypes.

One built by Sile and Debbie, a five channel device that hooked up to matlab. We were able to hear some different sounds and beats.

Second prototype was just the speaker hooked up to a frequency generator. We decided we liked the dynamic range of the Audio Logic Speakers.

Next week's prototype: Angela to build a voltage controlled oscillator that causes the pressure sensor to change the frequency, and thus, change the oscillation.

Go back.
Go forward.
