Analog Metal Detector Circuits

Title not fully descriptive of integrated CMOS op-amp and I said, but used in some specific integrated in projects Metal detector circuit with the same features as the previous microcontroller circuit can measure 1.5 meters pb circuit diagram has all the details a list of materials used in the coil winding information on page 5 of the pdf file

Circuit 4011B, 40408, LM318, 4016B, TLC555 (NE555 timer) based on the integrated these parts can be easily found in the market but there BY4O7 research, but I have a special diode can be difficult
