FelezJoo Discrimination Fix

After a few months of research for the problems of discrimination and “Coil Error” in the Felezjoo PI, I finally find a temporary solution that can make the device more useful. this problem is often encountered when the components used do not match the detailed description given by the developer of FelezJoo. Since the source code is not available, it …

Hammerhead PI metal detector

“Hammerhead” is a pulse induction (PI) metal detector design. It is intended primarily as a learning platform for experimenters, and as a base design on which to expand. This design is very much like other commercial PI detectors, which tend to have similar circuit designs, so it has the potential for good performance.This project includes a layout for a simple …

Terminator-3 metal detector

Terminator 3 is a coin searching metal detector that operates according to the induction balance principle (IB). The “Terminator-3” scheme was developed based on the Tesoro metal detector. However, there are significant differences from these metal detectors, both in its work principle, in the process of its manufacture or configuration.The main advantage of the Terminator-3 metal detector is the ability …

Chance PI assembling

The “Chance PI” metal detector uses the 1602 LCD display. We will connect the display to the microcontroller on the board via a 4-bit parallel interface. I will reproduce part of the scheme with the connection of the display. You can use a cable from the HDD drive as the wires for connecting the display, its pin header just went …
