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.
Build two isolated 8P8C cable specimens and record continuity and visible twist membership. Both map straight through, but only one keeps the intended pairs.
Sweep a passive piezo sounder and a 10 nF control. Use two scope traces and a known resistor to calculate conductance and susceptance.
Swap two MCP4922 voltages with an Arduino UNO. Compare the intermediate state after separate SPI updates with a shared LDAC pulse.
Use two film capacitors and two shunts to compare fast voltage sharing with the settled midpoint. Analyze both limits and a captured input ramp.
Make a negative rail from +5 V with an LM2662. Compare two pump speeds under two loads and separate measured ripple from capacitor droop.
Compare open and matched 5 m and 15 m coax cables, then use the reflected-step delays to estimate how fast the wave travels.
