Pulse Induction Metal Detector Board "Pirat" Ready Module assembled version

Description

Pulse Induction Metal Detector Board "Pirat" Ready Module assembled version
The presented Pirate metal detector board was developed and manufactured by PE Tracker on industrial equipment and tested with the necessary piping connected during pre-sale preparation. The developers have equipped it with two variable resistors for the convenience of setting up the metal detector and achieving the best result when searching. A speaker is connected to the product and 15 cm wires are brought out to connect the coil. Two microcircuits of the device are installed on the board on the panel, which allows the master to quickly replace them without soldering, both during mass assembly and during repair.
In addition, capacitors with a low temperature coefficient of resistance are installed in the device to prevent the temperature drift of the metal detector during operation. All boards have a protective mask and are washed after soldering with an alcohol solution. You can see the manufacturing quality of the offered PCBs of the Pirate metal detector by going to the photo gallery. For a general presentation, the pirate metal detector circuit can theoretically be divided into four main nodes:
Pulse generator based on NE555 timer.
Search coil pumping unit on IRF 740.
Two-channel operational amplifier on the K157UD2 microcircuit.
Transistor audio amplifier.
The sensitivity of the Pirate metal detector made on this board with a sensor Ø 28 cm is:
Coin 5 kopecks. USSR - 22 cm.
Large objects - 1.5 meters.
Photo may differ from the present.
But in no case is the functionality affected.
