Capture a BPW34 light signal near 173 Hz, then see how keeping fewer samples creates a 77 Hz alias without changing the circuit.
Pulse a Coilcraft LPS4018-333MRC through a current limiter and compare its incremental inductance in two measured current bands.
Measure a 1N4148 at 100 µA and 1 mA on two dry temperature plateaus. Use matched currents to separate forward-voltage drift from current error.
Pulse a Panasonic CR2032 with two known loads, measure the voltage droop and recovery, and calculate the effective ratio from paired scope captures.
Measure both windings of a Triad TY-145P at three audio frequencies. Compare a floating meter-only secondary with a 600 Ω load and locate the voltage drop.
Build an isolated USB-C sink fixture, map both plug orientations, then open one pull-down and compare the Configuration Channel and VBUS readings.
Wire two SN65HVD230 transceivers to one Pico. Try four CAN input combinations, measure CANH minus CANL and see why either node can make the bus dominant.
Clock the same eight bits through a SN74HC164N twice. Keep the LED dark during one transfer while the register outputs still change.
Use two SN74HC125 buffers and an Arduino UNO to compare a guarded handoff with a resistor-limited overlap. Measure both enable edges and the shared node.
Record the same small voltage step at two DC bias levels. Estimate a ceramic capacitor’s local capacitance and check the result against a film control.
