Induction Balance Metal Detectors use electromagnetic fields to detect metal objects. They consist of two coils: a transmitter and a receiver. The transmitter coil generates an alternating magnetic field, while the receiver coil is designed to cancel out this field in the absence of metal. When a metal object disrupts the balance between the coils, the detector senses a change in the electromagnetic field, indicating the presence of metal. These detectors are commonly used in treasure hunting, archaeology, and security.
Blitz PI Metal Detector Project Description: High-Performance Blitz PI Metal Detector Overview: The Blitz PI is a professional-grade Pulse Induction (PI) metal detector built on the powerful STM32F103 32-bit microcontroller. This project stands out due to its exceptional stability and high-speed signal processing, which is far superior to traditional 8-bit detectors. Key Technical Features: …
KROT_STM – F1 A continuation of the Krot MD line, using a modern 32-bit microcontroller from the STM32F103 series. The device is based on the KROT PRO MD firmware and case, and therefore has a similar menu and controls. It now features a single frequency range of 8-17 kHz, as well as the previous 88-101 …
Simple BFO metal detector BFO metal detector uses two generators. One generator uses a search coil, the second a smaller coil that is used to pattern the signal. By tuning the two coils so that their frequencies nearly match, the difference between the two frequencies begins to be heard through the speaker. The sound frequency …
How to program microcontrollers for Zabava-m1 r Zabava-m1 Zabava-m1 Zabava-m1 I program microcontrollers Zabava-m1 using the Algorithm Builder program and a programmer, the circuit diagram of which is present in the help system of this program. I take power for the microcontroller from the “crown” through the 78L05 stabilizer, be sure to …
Installation of parts and assembly of a homemade metal detector Zabava-m1 Installation of parts The parts are mounted on a piece of single-sided breadboard according to the diagram. The board size is selected based on the case size. The leads from the case of the R8 resistor are significantly larger than the holes in the …
Metal detector “Megatron” This metal detector was developed by Evgeniy based on the “Terminator Pro”. The device has shown itself to be the best, high-level discrimination, low current consumption of the device, cheapness and availability of parts, as well as the ability to work on heavy soils. The device board has been tested and …
SELECTIVE METAL DETECTOR SPECTRUM Modern industry offers a huge selection of various equipment for carrying out work on searching for metal objects in the ground, walls, water, etc. No fewer (if not more) different schemes are submitted to the public by amateur authors. Some author’s works have absolutely no analogues among factory devices, but still …
Simple and sensitive metal detector Here is an extremely simple, but worthy of existence, metal detector, for the production of which only one cheap integrated circuit op-amp TL084 is required. What is needed to assemble the circuit Quad operational amplifier TL084 Variable capacitor 100 pF Search coils Headphones The project was featured in Everyday Practical …
METAL DETECTOR TESORO TSGL SCHEME We present another rather successful scheme of the Tesoro Golden Sabre Light metal detector . In the lightweight version there is a discrimination mode and an all-metal mode, switched by a toggle switch. When installing parts according to the scheme, everything is balanced, when switching, there is no need to …
Détecteur de métaux Bonjour les Ptits Bricoloups ! ! Pour les ceusses qui pensaient (ceux qui peuvent) que j’étais en grêve….eh bien c’est raté ! Non, je travaillais pour vous tout simplement. En 2000, j’étais Prof d’atelier à Aytré près de La Rochelle. A l’époque, les élèves travaillaient encore à l’Ecole, eh oui, et j’avais …
