Wibbly wobbily wiggly lines
With my new 24PCBFA6G sensor and Myself Probe (which was nice enough to fit together with minimal faffing) I can detect squishing of the probe by simply measuring the output of the pressure sensor on my shiny new scope.
and as you can see a squish provides a good positive response (yellow and blue are the 2 outputs form the bridge and red is the difference between them ie the output)
(yes I know the 2 channels are on different scales, that’s just my incompetence but it demonstrates the point anyway)
EDIT: This is a better example
All that is required now is an input amp and some software to make the PIC do something interesting with these pulses.
