Hi there? I am experimenting with metal detector using PIC. I want to vary the inductance of the loop sensor in order to trigger the PIC to indicate the presence of metal. My problem is how could I simulate a variable inductance in Proteus ISIS. Any help would deeply appreciate. Thanks...
i am trying to build a PI metal detector for it i made the research, which states that with the presence of the metal the pwidth of the decaying pulse increases can any one guide me how to made a circuit that could detect the width of the decaying pulse and with this we can detect the presence of the metal or how the (...)
Hi every body I want to know how can I change my VLF metal detector to distinguish between two metal with the same type at nearby places? thanks a lot
I am looking for metal detector's shematic based on microcontroller. I'm especially interrest by the tesoro's metal detector shematics. If someone could help me. Thanks
I have stored 2 kind of metal detector based on microcontroller. I build both and i am sur it is good. Have a look at filemanager: Neron/metal_detector. If someone have other schematics i am interrest.
Hi guys! I'm looking for any schematic, pcb etc about metal detector. Only thing I need is a WORKING CIRCUIT. I anybody know where to find it, please tell to me. I´m looking metal detector schematics, pcb's theory, or any related thing, specially any circuit easy to make it.
hi, AVR based metal dedector.
I am looking for good and simple schematic of sensitive metal-detector on large width (approx. 1,5-2 meter). Please, help! Please search forum first or use google. and I think both elektor and EPE mag have published such projects. Alos try to post in right topic
Has anyone a scheme/circuit for a good metal detector?

hello I wanna buy metal detector to work for about maximum 50 cm but with high precision to find at least 20 coins together metal finders support this?
- Some time ago we discussed about the detector, but I havent foud anywhere more information about it. For example. Does anybody now how deep it recognizes metal and stuff? 0,5m? 1m? 1,5m?
hi i'm giving you metal detector schematic and pcb. its realy good. regards.
HOW can i get help of design a gold metal detector that deepest and sensetive one,,,,,,,,,,,,,,,, and how i get the sensor of it please help me:idea:
This is a microcontroller pulse metal detector.

twin loop Treasure Seeker by Robert and David Crone This pulse induction metal detector utilizes a dual-loop search coil for canceling ground effects and RF interference. It was published in the September, 1989 issue of ETI, a popular electronics magazine that is owned by UK publisher Wimbourne (...)
Hello I'm new to the forum and a total novice in electronics. I would apprecriate any help that can be offered about my project. I want to build a small metal detector, instead of having it beep or make any kind of noise when it detects metal I would like to have it signal by vibrating, or some element connected to it vibrating. I (...)
Dear Friends, I need to a simple circuit for metal detecting. The detection object is coins in the depth 10cm. I need this circuit for a small robot. So it's very good if i can connect alarm output of circuit to a microcontroller instead of a buzzer or LED. It's important that i know the details of circuit parts. Thanks
I wanna a metal detector circult which is test for aluminium casing drink. For example, the coke outer space metal. When the detector feel that is close, It will make a output which are logic one. (5V) Thank for help:D
hi all can anybody give me, schematic diagram for metal detector venuselectronics
This is the Eti 549 metal detector circuit I'm referring to. I'd really appreciate it if someone could guide me and tell me what's exactly happening in the transmitter section. The first stage is a relaxation oscillator producing 800 Hz which is being fed into the next stage, which is a Colpitt's oscillator, which modulates the signal to 130 Hz...i
Hey I've built a metal detector using a colpitts oscillator. I used two 1uF capacitors in series. I've been measuring the voltage output from the center tap of the two capacitors. When I bring metal close to the coil, the amplitude of the oscillations goes down to zero. Can anyone please explain why this happens? Someone told me that it (...)
