PicoDetector : a simple metal detector
https://www.electronics-lab.com/picodetector-simple-metal-detector/
Bruno Gavand build a simple metal detector using PIC12F683. He writes: The idea of this circuit is to hack PIC oscillator circuit, by replacing the crystal by a coil : the frequency of the oscillator then depends on presence of metal near the coil, just like in a classic metal detector. PicoDetector : a simple metal […]
