metal detector to illustrate Faraday's law. Metal Detector Basics An introductory description of how metal detectors work can be found online, 5 and a general description of metal detectors and their uses is given in C.L. Gar-rett's Modern Metal Detectors.6
The detector can detect a small metal coin at a distance of 15 centimeters. Find this and other hardware projects on Hackster.io. Pulse Induction (PI) systems use a single coil as both transmitter and receiver. This technology sends powerful, short bursts (pulses) of
A Simple BFO Metal Detector. A Very Simple Beat Frequency Oscillator type of Metal Detector. These are about the Simplest of all Metal Detector types, But still quite useful for many Detecting applications. And although this one is particularly simple, I find it works very well. For use outside on the ground the coil MUST have a Faraday
metal detector on the metal part of the chairs and it worked every time. The reason our results were as such was due to the fact that the beat frequency oscillator metal detector we tried building is meant to only find large metal objects at a close range.

2019/11/5Re: Help with a metal detector circuit. so if i run the coil on 12-18 volts.. it will feed back that higher voltage to the attiny and will fry the chip. All you've got to do to stop the 12V getting to the attiny sense input is to move the top of D2 to the attiny's VCC, in theory, and maybe increase the 10k value of R6.
