Metal Detector Schematics. White s surfmaster pi schematic diagram. The one coil design that has been used for this project is known as the pulse 1 metal detector.
The most difficult part is making. Schematics and construction notes for both one and two coil metal detectors. The one coil design that has been used for this project is known as the pulse 1 metal detector.
The metal detector circuit shown here must represent the limits of simplicity for a metal detector yet the design works surprisingly well.
The circuit was chosen for its learning value and deemed complex enough to mitigate a complete design from scratch. The beat frequency oscillator bfo is the simplest and oldest type of metal detector technology and is a good starting point for learning how metal detectors work. Schematics and construction notes for both one and two coil metal detectors. The first is called the search oscillator and the other is called the reference oscillator.
