Feb 03, 2020· You can build only an oscillator. In theory you can avoid building the second oscillator and use, instead, a little receiver AM radio near the circuit (see figure 6). You can hear the acoustic note or a variation of the noise on the speaker of your receiver when a metallic object is detected by your metal detector.

Dec 03, 2017· The Metal detector project is designed for metallic body detection by sensing variations in high frequency Eddy current losses. Using an externally-tuned circuit, they act as oscillators. The output signal level is altered by an approaching metallic object. The output signal is determined by supply current changes. Independent of supply voltage, this current is high or low, according to the
