Simple Metal Detector: 8 Steps (with Pictures)
Simple Metal Detector: The other day when I was searching instructables I come across on interesting and simple circuit for metal detector. It is build with 555, coil and few other components. Instructable that inspire me to do this project was this one. Main debate was...A Simple Metal Detector CHEMELEC
A Simple design based on a CS209A IC that can give surprising results and draws very little current from a 9 volt battery. It worked good on the Bench, But not so good outside for general metal detecting.Metal detector circuit diagrams and projects SatSleuth

The heart of this diy metal detector circuit is the CS209A IC. The metal detector is built with one 100µH coil that has 40 mm in diameter and isSensors Detectors: Metal Detectors electronic circuits
A BFO Metal Detector Not the best, but Simple, and Now with a PCB. __ Designed by G.L. Chemelec. A Simple Circuit 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 Detecting applications. .micro examples : PicoDetector
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.. To detect changes of main oscillator frequency, we ...Build this simple "electronic electroscope," a FET ...
This simple circuit can detect the invisible fields of voltage which surround all electrified objects. It acts as an electronic "electroscope."Crystal Radio Circuits techlib
Crystal Radio Audio Amplifier. Here is a simple audio amplifier using a TL431 shunt regulator. The amplifier will provide room filling volume from an ordinary crystal radio outfitted with a long wire antenna and good ground.Metal Detectors Theory and Practice VLF, PI and BFO ...
The Beat frequency oscillator (BFO) is the simplest (and oldest) type of metal detector technology and is a good starting point for learning how metal detectors work. The basic beat frequency metal detector employs two radio frequency oscillators which are tuned near the same frequency. The first is called the search oscillator and the other is called the reference oscillator.(PDF) Design a simple model of electrocardiograph | B. Z ...
The electrocardiograph is an electronic instrument used to produce a written record of the electrical activity of the heart. The electrical waveform produced by the heart is called an electrocardiogram or ECG (sometimes EKG after the German
