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.
Compare 2.50 mm and 2.54 mm headers with outside-jaw readings, corrected center spans and a complete Python analyzer for bounded differences.
