PicoDetector : a PIC-based simple and cheap metal detector. A short video clip is sometimes better than a long explanation : 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.
Hey guys and gals, I'm trying to build a metal detector that can detect foreign metal objects in otherwise non metallic material passing through a loop. Basically continuously searching and then alerting a user if it detected something metallic pass through it. My loop needs to be ~24 inches/0.6 meters in diameter, but I only need to detect objects within about 12 inches/0.3 meters away from ...
The metal detector circuit consists of two main components: transmitting and receiving . The transmitting node consists of a pulse generator on a KR1006V1 chip (an analog of NE555) and a powerful key on a KP505A field-effect transistor (an analog of IRF740, IRF840).

Pulse metal detector PI polonese We present one more (in addition to the numerous ones available on the site ) construction of an impulse metal detector. The details here are inexpensive, widespread, and the scheme itself is taken from the bourgeoisie, where, judging by the reviews, it passed all the tests and was highly appreciated.
Pulse Induction Metal Detector. This metal detector project named as GoldPic 3.01. Trevor R Hill designed this project to detect coins and jewelry on the beach and in shallow water. The timing and circuitry is optimized to detect small items like coins and rings at a good depth. The main part of this project is microcontroller PIC 16F84.
