Team:UC Davis/Signal Processing

Development began on the protoboard. Circuit designs were prepared using the CheapStat as a reference. SMD-ICs were soldered to DIP adapters and the potentiostat was wired for the first time. The protoboard became the primary device with which to develop the software. The protoboard was not designed with a switch to control current ranges, it did include noise however. Fast Fourier transform of the recorded signal showed that the largest component was from the 60 Hz range. Extensive testing showed that the noise was related to the protoboard itself as the signal persisted long after components were deteced. There was no other option but to continue the development by creating a printed circuit board.
