Building a ring tester that can test transformers and inductors for short turns, even in a circuitboard. It can easily identify shorted windings, including just 1 short turn. Irreplaceable, especially when fixing switching power supplies and inverters, but also for vintage CRT television and monitor high voltage transformers and deflection coils. It's a simple ring tester, testing the winding based on the number of damped oscillations it can make with a resonant capacitor. An internal short will turn a high Q factor transformer or inductor into a very low Q one, resulting in way less damped oscillations (rings). The Q factor is affected by the internal short turns way more than the inductance is. This tester can also ring test capacitors to estimate their dissipation factor.
