Hi to all
How can detect electrostatic field with ferrite rod ?
Anybody have circuit?
Best regards.

You need a journalist tape recorder. Dismantle the audio head and instead connect the ferrite, via preamp. You have here 2 versions. Treasure give great signal.

Will be discuss better this "case" in private RS forum. There are many other details.

Ivconic made modification in power supply. Simple only 10 K sensibility control is the best. The other potentiometers are replaced by fixed resistors. The switch is not necessary. Pin 9 is no connected to ground.

Hi,

Please explain this schematic (Electrostatic field detector with ferrite rod) more, how to build ferrite antenna like turn of wire and used capacitor ?

He will not say you...

better if you pay an hacker and get into his PC...

But I don't know if now he has removed any file from there already...

Dear firend Esteban, can you plase tell me were i can find a preamplifier and beep schematic, cause i want to make your Medium Distrance Treasure Locator.
Already have the tape recorder, ferrite and new oscilloscope and also digital signal generator to build and experiment with it.
Sorry for my english and i hope you can help me investigate with this simple circuit.
Kind regards
Nelson
Un abrazo hermano
