Really neat transparent RCD/GFI. (with schematic)

Last of the "trebley-audio" videos.. The circuitry in this is breathtakingly simple, and is based on standard components. Standby power is effectively zero.
The video of the new recording device isn't up to the standard of the original Moto G4, so I'll probably be going back, which is a shame as the audio was louder and clearer.

Here's Mike's "test" of a breaker that went really well from a viewers perspective.
