| What do capacitors have in common with wires in water or fingers touching metallic surfaces? Quite a lot. You can use skin impedance for a v...
| The proposed measurement principle is based on constant current, making the measurement completely insensitive to the series resistance. Th...
| A bad capacitor shows different capacitance values for charging and discharging; a perfect capacitor will have the same values. Knowing this...
| In the previous instalment [1] we saw how capacitors block DC but allow AC to pass through. But that most certainly isn't the end of it – vo...
| A capacity meter is more useful than you might expect.
| Now that I am at it, might as well add this function too. Sounds familiar? This is such a project. It measures frequency, period and duty cy...
| After the resistors that we discussed in the previous episode [1], it is now the capacitors' turn. Capacitors also can be considered resisto...
| Measure: Frequency + Period + Pulse + Pulse/period + Capacity + Event counting. Bonus: decode DCF77 pulses and show date and time. The DCF7...
| I was always envious of my friends analog ESR meter that allowed him to check and find bad capacitors while they were still in circuit. The...
