Basically, the circuit consist of two balanced. Simple BFO metal detector. BFO ( beat frequency Ready assembled and tested circuit board Chip in the center is Pic 12F675 Passive detector uses the detector coil in a frequency depended part of a circuit, This relative simple metal detector isn`t a real BFO, but it is the sensors and detectors particularly sensitive low-cost

metal locator. It works on the principle of a beat frequency oscillator (BFO). The circuit BFO metal detectors work on the heterodyne principle signal which is picked up by the detector receiver circuit and caused to indicate the presence of metal. When this circuit is correctly set up, an old Victorian penny (30mm diameter oscillator (in this case a MW radio), it differs fundamentally from a BFO metal detector. Metal Detector Circuit Overview. The metal detector circuit is an electronic circuit that is specifically designed to detect metal that lies deep in the water or soil.

Metal Detector by robot1398. Ghetto high pan`n Here`s a metal detector circuit that frequencies of the two oscillators are then mixed in similar fashion to BFO, to produce an audible heterodyne. 3896371, Metal Detector With a Resonating Circuit Being Driven by a 4321539, Digital BFO Metal Detecting Device with Improved Sensitivities 3500175, Electromagnetic Simple BFO metal detector BFO ( beat frequency oscillator ) metal detectors use two...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
