exercice de style #2: le circuit

Working with Elio Bidinost at the Sensor Lab. The objective is to build a circuit where a microphone would capture the sound environment. When the environment would be silent, vibrating motors would be activated to create a visual and sound wave in the textile layers. Here is the first version. The challenge was first to remove all kind of noise in the circuit. Then, it was to accurate the sensitivity of the microphone; at first, it was feeling touch and blowing, but not the environment sound waves. The following visualizations have been made with the Fritzing software.

Eventually, we will have to invert the microphone so silence will be the input instead of noise. We also might need to integrate a micro-controller to control the activation of the motors, so their own noise won't stop the output going on for a determinate period of time. Here are some short videos of the circuit while working (the vibrating motors are replaced with a LED for debugging reasons) and of the use of the oscilloscope to adjust the potentiometer.
