Hello, I've made this metal detector with 2 changes. 1) i didn't get 100nf (100v) capacitor. So i used 100nf (160v) capacitor. 2) i made coil with 0x, 22x, 72x windings. But now metal detector keeps buzzing all time. Are those changes that i made is the problem for it keeps buzzing all time? Please suggest an edit. Thanks

use the varistor to reduce the noise

[@sa3eedz568]

I think you should use a bigger variable resistor then trim until the sound stops'. You can instead add a resistor in series with the variable..

[@stargazer279]

This circuit has some flaws, it will be very unstable. Take note that is may or may not work. Some may be able to make it work. There are metal detector circuits on the internet that are working properly. Please take note the first stage of the circuit (transistor and buzzer) is wired wrong. Also, the soldering makes the circuit very unstable. Source: over 35 years of electronic engineering.

[@rtm5296]

Parece simples e eficiente para iniciantes como eu porem eu fiz o circuito em um app de simulaçao e acusou que o capacitor 1 estava em curto. Se puderem me ajudar com isso, eu agradeço.

هل هذا يكشف الذهب

[@stargazer279]

@@user-dl5jv3cr7y , You are asking if you can find gold with this. Well, i would say yes and no. Let me explain. Yes you can find some gold like rings and chains. But if you are looking to find some pure gold nuggets from a mine, you may not be able to detect much. If you wish to find gold nuggets, you will need a much better metal detector such as a Minelab detector.

How many volt the battery and the coil. How many turns and how I can increase the noise

[@yiannisyiannis]

If by noise you mean depth that the thing can detect... i dont think you can.. it is 3.7 to 4.5 volts.. and there are 2 coils of 20 turns each.. then you connect one of the leads of each coil to make a center tap and..yeh thats all.. follow his instructions
