Our metal detectors practical diagrams. The advantage of this type of metal detector is simple construction of both the device and the search coil, but a drawback is the high influence of soil conditions to the detector's perform-ance. Transmit/Receive (T/R) Figure 5 shows a block diagram of T/R type metal detector.
As a practical example, we'll set the search oscillator up to operate at a frequency of 100,100 Hz, and the reference oscillator to a frequency of 100,000 Hz. ... Here is an artist's diagram of the completed metal-detector unit. Any inexpensive AM transistor radio can be used in conjunction with the detector. Building The Loop
The above circuit diagram is of a low-cost metal detector using a single BC548 transistor and an old radio. This is just a Colpitts oscillator working in the medium band frequency with a radio to the same frequency. First, the radio and the circuit are put close, then the radio is tuned so that there is no sound from the radio. ...

Figure 2 – Block Diagram of the Pulse 1 Metal Detector The basic design of the metal detector consists of four parts as seen above. These are: • The power supply (four IC's), • The pulse generation circuit (four 555's, and coil), • The detection system (coil, amplifier and integrator), and • The instrumentation system (555).
The Simple BFO Metal Detector schematic diagram consists of several components, including two metal coils, two capacitors, a zener diode, and other electronic components. The two metal coils create an electromagnetic field, which can be detected by the metal object when it passes through the field. The two capacitors are used to adjust …
Here is what each of its features does: I. The Search Coil. Your metal detector's search coil is the circular loop of wire that generates a magnetic field and detects metal objects. You hold the metal detector so that the search coil is close to the ground and start sweeping it back and forth to find your treasure. II.
The following image shows the circuit diagram for do it yourself (DIY) metal detector circuit. Through the electronic circuit diagram it is possible to notice the availability of various electrical elements You can refer to the following article for a practical example of a metal detector that uses an Arduino circuit. Source Instructables.
A metal detector as the name indicates detects the presence of any metal that is found anywhere closed to it. This device is helpful in many aspects as it can detect the metals buried under the surface or hidden metal objects. The device may be fixed on the wall or on the stand, or it can be a handheld device or unit with a sensor enclosed in ...
3.1 Very Low Frequency (VLF) Detectors. VLF detectors are the most common type of metal detectors used today. They operate by transmitting and receiving electromagnetic fields at various frequencies. VLF detectors are highly versatile and suitable for a wide range of applications, from treasure hunting to relic hunting.
The most popular coil size is usually 6″, which works well when detecting specific items from under long grass, heavy soil, or sand. This size has a good detection depth making this coil perfect for coin-hunting enthusiasts as they will detect coins at good depths depending on the setup of your machine. Metal detector search coils are located ...

This is the reference oscillator, and is based on a Clapp Oscillator. The variable capacitor C11 is there to finely tune the frequency of oscillator, so that both the reference ...
Geiger-Müller Detector and Counting Statistics . Purpose To understand how a Geiger-Müller detector works and, by counting radiation events, to test the model that the Binomial, Poisson and Gaussian probability distributions describe, in different regions of parameter space, the statistics of counting experiments. We will also use
Step 1 – The Circuit Board. There are several diagrams available if you want to build your own circuit board. The first step in making your metal detector is to build the circuit board. This can be done in a couple of different ways, and there is an almost unlimited supply of circuit designs available online.

The first stage of the BFO metal detector, revolves around the transistor Q1. This is the reference oscillator, and is based on a Clapp Oscillator. The variable capacitor C11 is there to finely tune the frequency of oscillator, so that both the reference oscillator and the VFO are in sync and there is no heterodyne production at the output.
