An UltraSimple Receiver For 6 Meters Here is a simple VHF receiver you can build without any special components or test equipment. By Charles Kitchin, N1TEV This receiver uses superregeneration for high sensitivity and low parts count. It can receive both FM and AM modulated signals. This design differs from previous superregenerative circuits because it uses a "quench waveform" control ...
Metal Detector Circuit Diagram and WorkingElProCus. A Metal Detector Circuit using IC 555. A simple metal detector circuit diagram project is designed using IC 555 as you can see in the 555 timer circuits these circuits detect the metals and a magnet is near to the 10mH choke the o/p frequency circuit can be powered from a power supply which can provide an o/p DC ...
· Metal detectors are typically very sensitive and need to be calibrated periodically. The goal of this calibration is to loe the extremely narrow sensitivity setting that will allow you to loe metal without the metal detector producing excess chatter. Turn the metal detector on, adjust the sensitivity to the maximum setting and adjust the discrimination to the minimum setting. Pass the ...
Metal Detectors in the food industry are designed to keep up with the normal flow of the production process. Conveyorized metal detectors can run at speeds of up to 120 meters a minute, which is just over 393 feet! This allows food metal detectors to inspect hundreds of products a minute without skipping a beat. Pipeline and flowthrough metal ...
· To test resistance with this milliohm meter circuit, I took a 2" (5CM) length of solder and flattened the ends with pliers. I placed the test probes in each end and the meter pointer was halfway between zero and .01 and measured .005 ohms. With my tester, I .

With 2 Ω circuit resistance and the minimum voltage of 9 Volt, the current over the coil will reach about Ampere in the 250µsec mentioned above, which is more than adequate for a general purpose pulse induction metal detector with deep seeking capabilities.
· These metal detector circuits are being used in plenty of places. Most of the security officers use it to detect metal devices like guns, knives, etc. A metal detector is a circuit that senses any metallic object closeby. These metal objects are very useful to detect the presence of any hidden object. A simple metal detector uses a 555 Timer . Metal Detector Circuit Diagram and Working. Jul ...

A sampling circuit in the metal detector is set to monitor the length of the reflected pulse. By comparing it to the expected length, the circuit can determine if another magnetic field has caused the reflected pulse to take longer to decay. If the decay of the reflected pulse takes more than a few microseconds longer than normal, there is probably a metal object interfering with it. The ...
· 5,444. Jul 17, 2015. #2. The entire premise of a "null detector" is that there is some voltage that the "adjustable voltage source" can be set to that causes zero current to flow through the "null detector", which is usually a high resistance voltmeter. In the stated problem, what is .
