making a noise sniffer help

Yeah me to Id love to know about that device

what you're supposed to do i sget an old cassette walkman, or some kind of tape player, pull out the head that reads the cassettes, and thats about it. i went an picked up an old panasonic taperecorder for a dollar and gutted the motor out of it, extended the wires on the head (there were only five) so they would be long enough to reach around the inside of a car, modified the play button so it was just a simple switch.

now, i think that when i took the motor and gears out i may have ungrounded somthing that i needed, becasue when i first got it i could hear static through the speaker when i hit play, and now when i hit the switch there is nothing, but im still working on it. maybe i'l try again and leave everything in tact with a different player.

ideally, when it is all up and running, you hit play, it activates the tape head which picks up electromagnetic signals, much like those that cause radiated noises in stereos, and other types of interferences as well. the device "sniffs" out the source of the noise by playing it through the speaker. natrually, the louder the noise on the speaker, the closer you are to the source.

i figure it will help determine if the ign system is causing noise, or the charging system, or an acc. in the vehicle, or where a certian wire is shorted out at, with little to no thinking.

Wow I would have never thought of that, hell I was think it was some elobrate thing you had to build from radio shark parts

Im going to give it a shot with my old walkman

Thanks
