Hi i wonder that, can i use your circuit's outputs which already drives spekaer for arduino? İ want to make a circuit that is sensing battaries,big ones or small ones....please help and give an idea...thanks..
Thank you dear friend you have made physics and electronics entertaining and tutorial homes will not flourish I wish you the best The search coil indicator L increases and audio frequency gets reduced thanks
Bonjour je vous demande s'il serait possible de me faire connaître quels sont les composants électronique pour fabriquer un détecteur de métaux à double bobine je vous en remercie
Hi, this works! But with small changes. I have a need to tell you this. A few months ago, I struggled with this (then I didn't know how to read electrical schematics) and I didn't manage to put it together. But now, last night, I made it! It is very functional and useful! But how did I do it? Replace the 2.2uF capacitors with 1uF, also very important, replace the resistor around 47k with 4.7k, instead of connecting the minus to pin 1, connect it to the minus of the capacitor that goes from pin 3. This way, this works just fine. The buzzer buzzes, when you get close to the metal it changes the sound. Use a 9V battery to make it work nicely. I did not use an excessively long wire, if you use a very long one, a few meters, then you will have a stronger effect. It also works with a diameter of 10 cm, but I put 5 cm (I used the same length of wire). I put it through the rod and that's it. I also added an LED, connected in parallel with the buzzer so that I know when it is on, although the buzzer buzzes, for the sake of aesthetics, I like it. Greetings and cheers! I am available for additional questions! Update: Instead of using a resistor, use a potentiometer, I used a 100k. It is very easy and precise to set the diode and the buzzer to react only if the metal is approached. Greeting!
@@shiva.chennai Hi, I honestly haven't tested whether it works with non-ferrous metals so I can't answer that question. It works with aluminum, iron... That's the only thing I've tested.
merhabalar ben bu devreyi bir okul projesi için yapıcam fakat kullanıgınız buzzer mı yoksa hoparlör mü ? buzzer olsa bir direncle baglanmalı sanırım degil
David A Loving Sir,notice the video carefully at 3.21sec..The Metal Detector is sounding shrill (not like a Dove). Actually there is a real Dove in the meadow or grassland where this you tuber has gone to verify the work of his metal detector project..☺☺
sooo where do you solder the cap's or the resistor? if your gonna show us how to make it then show us... don't just poke some components through cardboard and expect us to know how they are set up.. I mean if we knew that we wouldn't need to watch this eh?....not all of us have ESP...
