Using a cutting tool, make a notch in each sheet with a width of 5 mm and a depth of 10 mm. The coils will be made from 0.3mm varnished copper wire (30 SWB) following the procedure: Seal the start of the first wrap at point A on sheet 1. Passing through the notch around the side of the sheet, for coil L1).

4 12,846 6 minutes read. "Hammerhead" is a pulse induction (PI) metal detector design. It is intended primarily as a learning platform for experimenters, and as a base design on which to expand. This design is very much like other commercial PI detectors, which tend to have similar circuit designs, so it has the potential for good …

BC558 PNP transistor. 560Ω resistor. 47Ω output resistance-you can choose this resistor in range of 10Ω to 100Ω. The ESR measurement circuit can be divided into two parts, the 555 timer and the output stage. 1- The NE555 timer is a conventional astable Multi-vibrator oscillator, may generate hundreds of kHz square wave.

The scheme can use a search coil consisting of three turns of a computer cable "twisted pair" (without a screen), intended for laying indoors. You can also use a coil of ordinary enamelled wire. The principle of operation of a pulsed metal detector "VINTIK-PI" is based on the excitation of pulsed eddy currents in the area of a metal object.
