Modified version of the Clone PI-W The 14th version of the circuit board turned out to be quite successful. Today, the commercial attractiveness of the device has significantly decreased – even an increase in the price of scrap metal does not lead to demand for this device among traders. I hardly see metal hunters in …
Connecting Raspberry Pi to 4G network In the Internet of Things IoT projects shared in the previous articles, we noticed that they usually have one thing in common: they rely on Wi-Fi hotspots and connect to the Internet network through this hotspot. Connecting to an Internet network via a Wi-Fi hotspot is perfect if you …
GPS tracker using A9G GPRS/GPS module In this article, we will make a GPS tracker using the A9G GPRS/GPS module and Arduino development board. The A9G module GPS tracker based on Maduino is a product based on IoT (Internet of Things) solutions that integrates the microcontroller ATSAMD21G18 with the best power management and storage functions, and …
Arduino and PN532 NFC module In this article, we will use a development board based on Arduino and PN532 NFC module – Maduino Zero NFC board. Maduino Zero NFC board is an IoT solution based on Atmel’s 32-bit SAMD21 MCU and NXP near field communication controller PN532. This development board can be used in payment applications, entrance …
Solar light controller based on Arduino development board This article mainly introduces a light sensing switch unit controlled by Arduino. Its main use is to control solar lights to turn on outdoors in darkness, but it can be used in many more applications. This guide will walk you through every aspect of the building process. This article has …

Metal Detector PIRAT MTX The PIRAT MTX metal detector has ended up in need of repair. I quickly sketched out its circuit, PIRAT MTX, and took a couple of photos inside the electronic block. In case someone has to repair such a metal detector, as quite a few of them have been produced. The Detector …
Metal detector Thunder-4 The device is designed for searching in “quiet” soils, following the principle – I hear everything. That is, black and colored metals without ignoring. This model does not replace the previous one but complements the series with a few different features. Sync detector, similar to Thunder-3. Similar to Thunder-3. Sensor imbalance during …
METAL DETECTOR THUNDER 3 THUNDER-3 SCHEME AND DESCRIPTION The metal detector is designed for searching for metals in the ground (and beyond) with discrimination by types (ferrous and non-ferrous). Type: VLF-IB. The search for metal objects is carried out by scanning the magnetic field of the ground and registering changes in the primary field due …
Improved Pulse Metal Detector Like metal detectors of other types, Pulse Induction (PI) metal detectors are continuously being improved. The application of new circuitry solutions has led to even higher sensitivity in these devices. For example, sensitivity of the metal object detector described in the previous section can be enhanced. In the author’s opinion, the …
Simple Metal Detector (Pinpointer) Among the advantages of the device, we can mention very low power consumption (5 mA from a “Krona” battery), ease of adjustment, and the absence of problems with any interference. simple metal pinpointer detector . Device scheme: Its sensitive element is the oscillatory circuit of the generator, assembled according to the …
