I am liking these piezos. Not sure about how the frequency differences affect my purpose but this seems very promising for a pressure sensor. And super cheap…. working with the Propeller Quickstart today.
And I got the COM port reading the output on Processing! My first exploration into COM vs UDP etc on Mac.
Also my paper circuit art was displayed at the Green Gallery at the Reinvention: The Mail Art Show at Green Gallery Nashville. The circuit was still in fine form. Happy to see it working as planned.
