- First of all, you will need to arm yourself with an unused empty CD case. Then you need to take the radio. It will need to be attached by the back to the inside of the first casement of the CD case. This can be done with the help of double-sided tape, if it is not at hand, then you can use a plaster with adhesive tape.
- After that, take a calculator. In this case, the simplest one that students usually use is suitable. It will need to be attached in the same way as the receiver, but only on the inside of the casement of the CD case.
- Then, you will need to turn on the radio and make sure that it is tuned to the AM reception frequency. You will also need to configure it further. To do this, you will need to switch the receiver to the highest frequency in this range. At the same time it is important that there were no radio stations on the frequency selected by you, otherwise your detector will not work. If the highest frequency is occupied by the radio station, adjust it so that you can be as close to the high frequency as possible, but at the same time only noise would be heard from the speakers.
- On this, the instruction on how to make a metal detector with your own hands does not end there, because in order for the device to be comfortable to hold, you will need to make a handle for it. To do this, fit the usual wooden stick from a mop, of small diameter. It will need to be fixed in the center. To do this, in the box from the CD you will need to make a small hole, you can cut it with an ordinary knife.After that, a wooden stick will need to push into it and fix the nails from the inside and outside. In order for it to hold well, it will be necessary to drive the nails not fully, so that the caps do not allow your wooden handle to pop out of the case.
