With Erin's new schematic using IC LM386, we decided to try a couple different exercises. The first was a feedback loop using a piezo element. By trying out different surfaces with different measures of hollowness, we experimented with the length of sound, the pitch, and hollow materials that can become a speaker. The Constancy of the loop was something distinctly different and inspiring, in that the inputs we had used so far primarily came from the schematics, different resistors and capacitors, and speakers. This time, the material which served as the sounding board also became the source of the sound, creating an infinite loop. The simplicity of it was quite beautiful. | With Erin's new schematic using IC LM386, we decided to try a couple different exercises. The first was a feedback loop using a piezo element.

Then we experimented with capturing radio waves, using the open wires, speakers, and the same schematic. | |||
