[QUOTE="Charles Harrigan, post: 39805, member: 23"] Re: OT: those ghost hunting shows and their technology if you ever see a picture of an orb, it is a piece of dust just in front of the lens that was illuminated by the flash. I can make one of those pictures right now if you wanted. There are also many effects that can be done with long exposures to make "unnatural" things appear. Any high impedance multi-meter will read a voltage when the probes are in the air. It could be caused by anything from nearby AC lines to RF energy in the air. You're essentially measuring the universe, and there's quite a bit going on out there. Also scopes give some interesting patterns when left in x/y mode connected to antennas of differing frequencies. Also if you have a recorder with a high impedance input connected to a piece of wire, with the gain turned all the way up, it could be receiving any number of signals, from police to CB to god knows what.
