So I wanted to drill into my wall but was unsure if there's a wire behind I don't want to cut through but didn't have a sniffer.

I'm now using my CardPuter ADV with literally just a jumper wire on an ADC pin as an antenna... and it can detect electrical fields inside walls!

I can't believe it but: it actually works really well for finding live wires !!! inside walls !!!.

As always, better use a real sniffer but I really like this!
