Simple BFO Metal Detector
A Very Simple "Beat Frequency Oscillator" type of Metal Detector.
These are about the Simplest of all Metal Detector types,
But still quite useful for many De...
Pulse Induction Metal Detector
This project is offered totally Free for those who are interested in it.
I have tried to make this article as complete as possible, but I will Not

Metal Detector circuit
The circuit described here is that of a metal detector. The opera- tion of the circuit is based on superheterodyning principle which is commonly used in superhe...
Metal Detector
A single chip metal detecor with a range of a few inches. This is useful for decting nails or screws in walls and floors, or for locating buried mains cable....

Two-component metal detector
The circuit shown must represent the limits of simplicity for a metal detector. It uses a single 4093 quad Schmitt NAND IC and a search coil -- and of course a ...
