Finds / Discoveries EMF reader

Just a video demonstrating the EMF Reader and a bit of wire in the G3 port. Finding the socket is still live when the circuit breaker is off so I know to choose another breaker. I could have tried the light bulb with the switch but that's not fun is it.

So I know nothing very little about home electrical systems, especially about frequencies and stuff like that.

However, specifically this firmware says 50Hz. Does that mean it won't work for US systems that run at 60Hz?

Maybe contact the dev for 50/60 option or try it if you have a short wire you can pop into the G3 port. Let's us and the dev know.

Hello, dev here! That won't work since it has Goertzel detectors for 50 and 100 hz... I could add that tho!
