+====Piezos/radio waves====
+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.

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

-The basic principle is to have different compartments in a rotating wheel come in contact with a piezo element and mini vibrating motor.
+The mechanism itself is quite simple compared to the original design of a Drehorgel. I placed a plastic cylinder filled with different materials in the middle of a square made with metal frames. With a handle attached to one side and the piezo microphone going into the other, I can control the rate of how fast the "Drehorgel" will rotate.

-The original idea was to create the Drehorgel out of cardboard. The major cogwheel would be rotated by a smaller cogwheel, which can be rotated using a handle outside the box. I planned to attach the breadboard and wires on the inner walls of the box so that they can be close enough to come in contact with the materials and stay out of sight when in operation. With cardboard, however, the audience couldn't see the interaction between the piezo and materials, and that was one of the goals for this assignment. So I decided to use metal spokes as the alternative material for design simplicity and transparency.
