I'm not a big believer in ghosts and all those paranormal reality shows only ever seem to film ghosts with no other aspiration than to knock on stuff however EMF is something I find interesting because we're surrounded by electro magnetic radiation (whether or not you believe it's paranormal is up to you) and I wanted to build a EMF detector - so I did and here it is.
there is an audio output so you can hear/record the actual EMF being displayed on the meter.
it's quite important that you have the pickup inductor mounted away from the device (as you can see in the picture) because you don't want to pickup the EMF of the device (not that there's much of it!)
so if you go out ghost hunting with this - make sure you send me the pictures of the places you're hunting cause I love abandoned places.
and if you record anything weird send me a link!
