This project focuses on the adaptation, and construction of a commonly available schematic for a Pulse Induction (PI) metal detector.
The background information of the history and uses of metal detectors is presented as well as the design criteria for out particular project. The theory behind how a basic PI metal detector works is examined, along with the basic details of a readily available design for a detector.
A detailed examination of the chosen schematics and the function of each component is examined and explained, as well as explanations for certain choices of component values.
Project Aim
The aim of this project was to create a circuit that was capable of detecting metal. It had to be battery powered and use a commonly available and understood design. In addition to this, the circuit design had to be relatively simple and compact so as to fit on a size limited Printed Circuit Board (PCB) board (due to the use of the EAGLE PCB layout tool).
