A picture of Shaumik trying to 3D print the aqueduct-like structure
We decided to go to the innovation studio to perform some tasks on the project. the first thing we did was to use the soldering iron to solder all the defective piezo and then tested them all out to make sure they were working. we then connected the set of piezo on a board to test whether series and parallel connections produced the most voltage since our previous test did not give any strong confirmation for either. after testing which connection works best, we then set up a circuit consisting of a 470 micro farad capacitor which was connected in series with a diode to ensure there is unidirectional flow of voltage and hence current. other component were also attached to it and through a continuous application of pressure to the piezo disc, we were able to charge the capacitor to about 1.9volts which was very constant until the capacitor was discharged. we attempted to 3D print an aqueduct-like structure to focus the pressure on the piezo crystals. this was however not successful as the 3D printer was malfunctioning
