Gold Detector Circuit | How to Make Gold Detectors
08.10.2019 · Gold Detector Circuit. At this point the voltages within the coil RX are zero and we continue to increase the gain slightly. and moving the coils slightly. We repeat the process several times, increasing the gain every time. The higher the gain, always having the ability to locate the zero point, the more reliable the detector will be. Attention always drives the coils from full contact to ...
Gold Detector Schematic - Electronic Schematic …
Here the very simple and easy build gold detector circuit. The circuit capable to sense gold or metal or coins from a distance of about 20cm, depending on the size of the object to detect. The circuit oscillates at about 140kHz and a harmonic of this frequency is detected by an AM radio. You can simply tune the radio receiver until a squeal is detected. When the search coil is placed near a ...
