Below is an example schematic from one of the paper explaining how to build a pulse induction metal detector I understand the most of the circuit, the problem I am having is understanding what the inputs and outputs should look like on IC4.
Aug 30, 2013 ee pulse induction 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 superhet receivers. The circuit utilises two RF oscillators. The frequencies of both oscillators are fixed at 5.5 MHz.
Dec 28, 2019 DIY KIT 46- Metal detector DIY electronic kit. Posted on December 28, 2019. April 24, 2020. by BuildCircuit. This is yet another metal detector kit for electronics beginners. After assembling the kit, if you take the kit close to a metal, the buzzer will turn on and the LED will flash. The sensitivity of the kit can be adjusted using the ...
Tracker PI-2 metal detector. The microcontroller-based pulse induction metal detector Tracker PI appeared on the market back in 2003, and immediately gained immense popularity among users. Then the circuit received some improvements, and several versions of firmware were released including and deep and from the first Tracer appeared ...
Figure 3 Schematic of the Pulse 1 Metal Detector Power Supply The power for the metal detector was supplied by 12V battery or supply. The power supply circuitry then regulated this using the REG1117A voltage regulator allowing for voltage consumption of the battery down to about 3V. The LT1054 provided

May 29, 2021 Pulse induction systems use a single coil as both the receiver and the transmitter. This DIY metal detector has a pulse induction system, and it can differentiate between ferrous and non-ferrous metals. Additionally, it is a symbiosis of Arduino and Android and has high sensitivity.
What I found were forums packed with very intelligent people working on homebrew detectors, schematics, circuits, and designs with the electrical engineering knowledge to make very interesting and cost effective metal detectors. I was delighted to find several schematics for Pulse Induction, VLF, and CCO detectors on the Geotech forum.

Very powerful yet home metal detector (DIY)-Pulse induction Metal meta detector Almeta PI deep Search. How to build a homemade metal detector, a simple house project that can quickly turn catastrophic if you encounter electricity, gas and water pipes, weve compiled a list of the top 19 DIY Metal detector plans from all over the Internet.
Apr 11, 2016 Looks promising. I built quite a few PI detectors myself, based on Microchip PIC controllers. One of the reasons of your low sensitivity might be the 10x flyback pulse amplifier. Normally, this is 1M/1K 1000x if you have a single amplifier. Also, the battery voltage to monitor is the 12V, not the 3V.
The PULSE AR III is a pulse induction metal detector up to 5 m depth ... The various searchcoils for the PULSE AR III are connected to the electronic unit in which a special circuit mechanism controls the coil electricity and adjusts the adequate search frequency automatically. By using the appropriate searchcoils (25 cm or 45 cm) smaller and ...

May 28, 2021 Pulse induction metal detectors are resistant to highly conductive minerals in the soil thanks to this pulse technology. It is only looking for metal. After detecting a metal, a sampling circuit determines the duration of the reverse polarity and
Feb 17, 2019 2019-02-17. 2019-02-27. by ukasz Podkalicki. This experimental project shows how to build a simple PI (Pulse Induction) metal detector based on ATtiny13 / AVR microcontroller. My goals were to make a circuit as simple as possible and to use only popular / cheap electronic parts. The device has been tested with very small coil (55mm diameter ...
was a simple metal detector. Later, I built various different metal detectors from plans published in electronics magazines. Today, the prices for metal detectors vary from a few hundred to a thousand Euro, and therefore I have decided to design one of my own an improved version of the pulse induction metal detector.
Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object. A sampling circuit measures the pulse and sends it to an integrator, which generates an audio tone.
