Yes! This type of situation is yours or not, if you want to make your metal detector, then this article is written just for you.

Making a metal detector on your own is quite a nice and at the same time fun activity. However, to make a simple metal detector you have to have a lot more control over different types of circuits. But today we will learn how to make a metal detector coil even with some common household things around.

If you can bring this matter under your control, it will become a fun time activity to spend time with your children. Even if you don’t know how to build a metal detector, then this article will come in handy.

Did you know that you can easily make a metal detector with very simple things in your home, such as a radio and a calculator?

Again, you can turn your own constantly used smartphone into a metal detector in a matter of moments. Anyway, this might not tell you how to make a metal detector to find gold, but you will have some decent metal detector to play with your kids.

And finally, build your metal detector quite easily by assembling several parts of a conventional metal detector. But before you do that, you must know how a metal detector works.

How to make a metal detector

We will discuss some of the easy ways to make a homemade metal detector. So, if you are interested in how to make a homemade metal detector, then be with us. Within a few reading and practicing will able to know how to make a powerful metal detector. Even you will be a proud owner of a home made metal detector.

Making your metal detector is not that hard job, this article will guide you through everything you need to know about how to build a metal detector.

The first method: Detect metal with radio and calculator

The first thing you need to do is move the radio to the AM seating. Also, keep in mind that it should be a static sound so that there is no setting in any one station.

This static sound lets you know if there is any metal on the front. That is why static sound is so important.

In the second step, you will convert this radio antenna as a search head. To do this you first need to turn on the calculator. Then the two devices should be placed on the back of each other.

However, in this case, care must be taken so that a pulse tone comes from the radio. For this, you may have to place both devices at a special angle or position. Then you can get this tone.

Thirdly, you have to tape these two devices to the position where you will get this pulse tone. Whenever this radio and calculator produces the right tone, it is in the same position but you have to tap, otherwise, your metal detector will not work.

If it turns out that you have to tap at an angle that makes it difficult to hold the device, then there is nothing to worry about. You can stick this whole device in a longboard. Then you can work only by holding the board without holding the device later.

Like a complete metal detector, this device will work like your search coil and you will get a distinct sound when you hold this device on top of any metal.

If you fit this search coil into a shaft, you will get a feel of a real metal detector. In this case, any old long stick of the house, or broomstick can come in handy.

Then you can test this device on any metal in the house if you want. First place a metal spoon on your table, then hold this search coil on that spoon.

You will see a kind of beeping sound coming from your radio soundbox. Then you need to understand that your metal detector can detect the spoon.

This is also an answer to the question, how to make a homemade metal detector with a magnet. Because the magnet from the radio soundbox comes quite handy in this process.

Recognize, now your metal detector is working well. You can then take your child out to the yard or somewhere else. Surprise everyone by detecting metal with this metal detector. Now you know how to make a metal detector out of household items. Now it’s time for you to explore some professional metal detectors for beginner.

Method 2: Convert your smartphone to a metal detector

So, you want to know, how to make a metal detector with a phone? Stay with us…

For this, you need to download a metal detector application. Now the question may come, why any kind of application installed on the mobile phone will work as a homemade metal detector?

The answer is that your mobile phone is also an electronic device. And that’s exactly why the magnetic field is created from it. This might be the easiest answer to the question, how to make a homemade metal detector.

And if you can control or detect the coming and going of this magnetic field, then it is possible to convert it into a metal detector.

And so, you go to the mobile app store and download a good rating metal detector application. If you search in the App Store by typing “Metal Detector”, then you will see some applications in the search results.

Next, hold your mobile phone with the application open on any metal. You will notice that there will be some changes in the magnetic field option on your phone.

If the data in the application changes when you put it in a metal object in the cell, then you will understand that your metal detector application is working properly.

Now the question that may come to your mind is how to detect metal in the application. The answer is that when you place the smartphone on a metal, the magnetic field of your phone will also change.

With the application, you can diagnose the change correctly if you want. And this is how a smartphone can be easily converted to a metal detector.

And that’s why when you place your smartphone on a metal, you can see that there is a metal in front of your phone by noticing the changes in its magnetic field.

Method 3: You can assemble the hardware of the metal detector

You can easily make your own metal detector by purchasing this type of separate hardware. However, these will be very early metal detectors.

It is better not to expect the service of Beach Hunting, Gold Hunting or Underwater Metal Detector from these.

You can buy different types of metal detector kits in the market. Which of these includes coils and shafts. Other kits were found to have only the control box. This way you can properly verify the kits you need to build a metal detector.

For a control box, you need to solder all the circuits. And so, when buying a kit, you have to buy a soldering gun.

If you have never soldered before, you will need the help of a professional. Also, you have to learn soldering first.

When you have assembled all the components, it will be time to test your metal detector. And so, put different types of metal on the floor and put your metal detector there. See how well your new metal detector is detecting all metals.
