	I started with a wooden frame which surrounds an inner base plate. I divided the plate into two halves, one with acoustic foam and the other with lines and circles engraved. On the front side I attached a wire frame and connected it loosely to the body. Furthermore, I have plastic hair of a broom built into the frame. The piezo microphone is glued to the base plate. Below it are the audio interface, a small power bench and the Raspberry PI, which are mounted on the feet. They are hidden by the frame. It is important to place damping bouncers under the feet. This prevents the transmission of foreign vibrations to the microphone.		I started with a wooden frame which surrounds an inner base plate.

	For this effect I used the [https://en.wikipedia.org/wiki/Pitch_(music) pitch] example in the PD-documentation by Miller Puckette. The pitch requires a certain span of audio, therefore we need to use an array. Because I did not wanted to have a static factor for the pitch I create a sine wave as factor to modulate the input. For every instance a pseudo-random growth rate and pitch range are generated.

	==~~Conclusion~~==		==Retrospection==

			It was the first time I soldered a circuit board and cost me more time than I thought. Also programming with components on a graphic interface was a new experience for me. I think as a computer science student it is still more comfortable for me to write my code as text. I tried to write clean and commented code as good as possible, but general coding convention did not fit in the approach of Pure Data.
