Week 4, we were concentrating more on getting our specs right. Our timeline suggested that we had to begin with the electrical design, but we were still waiting more our piezo crystals order, that we got the night after lab. We then proceeded with finishing the Creo model of the shoe sole and we tried to mess around with the electrical devices we got from the lab. We started with a breadboard and connected diodes, resistors and capacitors trying to build a functional circuit, using a 9 V battery as the power source. While playing with the circuits, we did some research online about the optimal capacitance that we should be using for the circuit we were intending to build. We also got the chance to talk to Dr. Fred Allen to get an idea of how to control the amount of voltage going to the capacitor using a voltage regulator. After lab we headed to the Electrical Engineering department in Bossone to get the voltage regulator and a multi-meter to use when working at the dorm.
