Above are some of the process photos for this project. As the project went along I realized that some if not all of what I wanted to achieve was not going to work.
So this project didn’t work out to be as pretty as I would have liked but in the end it does do what I wanted it to do which was show two different frequency waveforms generating a phaseshifting effect.
One of the things that I need to make this project better is a second piezo mic to pic up both of the outputs so that I can “remove” the motor noise and isolate the bell sounds, run them through a spectrometer or oscilloscope and show the phase cancellation.
