How do you know it works at all?...can anyone help me to explain how the attached circuit work? can it detect metal easily?
It doesn't look much like a Colpitts oscillator to me!I'm studying about metal detector using colpitts oscillator, can anyone help me to explain how the attached circuit work? can it detect metal easily? and the function of capacitors?
It's a common (grounded) base Colpitts oscillator.It doesn't look much like a Colpitts oscillator to me!
Yes,on looking at it,& Googling,I see the resemblance.It's a common (grounded) base Colpitts oscillator.
