Nothing was easier than taking the protoboard and mounting one of the old golden resistors as a shunt to and test … some ‘piezos’ (ultrasonic piezo transducers). The ‘piezos’ that we used as a DUT (device under test) were exactly the same ones which we used earlier in the previous two updates:

It is very straightforward – connections are as shown in the instructions.
We set the shunt resistor value, selected the frequency fairly broadly, and then increased the number of steps (10 step resolution is not really representative).
