Video about the pirate metal detector



Materials:
1_payment
2_plastic pipe
3_link of lithium batteries (or other power supply) for 12 volts
4_ wire (preferably immunity to interference)
5_ copper wire d 0.6 mm
6_ speaker
7_ regulator
8_case for fixing the board

To start, we make a board as in the diagram
Next, solder the speaker, toggle switch and power source, solder the cable and placed in the case
We glue the body to the pipe (no metal fasteners!), We make a handle convenient for you.
We make an “antenna” from wire, for example, winding it onto a bucket, about 20-24 turns, fasten it with electrical tape (you can also put it in some kind of case), solder it to the cable and fasten it to the end at an angle convenient for you.
