Metal Detector based Attiny13 Description This Metal Detector based Attiny13 is based on the principle of frequency displacement when a magnetic material is close to the oscillator coil. At first the microcontroller gets the frequency of oscillation, when the frequency change it lights one to four leds, according to the displacement amount. Components BAT – …
Review of Three Inexpensive Metal Detector Kits Review and Comparison of Three Inexpensive Metal Detector Kits A metal detector is a device used to detect the presence of metal objects in the ground or other materials. It works by generating an electromagnetic field and then measuring the response of any nearby metal objects to that …
Description Pulse Induction (PI) metal detector operates on a principle based on sending short pulses of electrical current through a coil to create a magnetic field. This pulse lasts for a very short period, usually microseconds. When the pulse is transmitted, the magnetic field spreads outward from the coil. If there is a metal object …

Golden Sensitivity 3D Ground Scanner The term “Golden Sensitivity 3D Ground Scanner” refers to a class of advanced metal detection and subsurface imaging devices that use sophisticated magnetic field sensors to create three-dimensional visualizations of buried objects and underground structures. These scanners are specifically designed for treasure hunting, archaeological exploration, and locating deeply buried metallic …
The deep metal detector DBP 2010 There are several errors in the schematic of The deep metal detector DBP 2010, which may have been introduced intentionally or unintentionally. DBP 2010 Main PCB Parts List Resistors (1% Metal Film) Reference Value R1 22 kΩ R2 684 kΩ R3 317 kΩ R4 120 kΩ R5, R20 5.6 …
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 …
Clone Pi AVR Metal Detector As the warm weather approaches, I decided to make this, a little more serious than the old AVT metal detector (MD). Advantages – LCD, settings can be changed, no expensive parts, more stable (than AVT) at low temperatures, easy adjustment, reaches decent depth, shows battery voltage and turns off when …
Metal detector on AVR microcontroller Since ancient times, people have been attracted by devices for searching for hidden metal objects. The reasons for this interest are varied. Builders are interested in the location of metal reinforcement in the walls, treasure hunters dream of finding a jug of gold coins in the ruins of an old …
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 …
