The metal detector was made
The metal detector was made by the radio and some electronic pieces became possible
You will only need 8 pieces of electronic equipment that you can get from any old electronic device or better bought from a very cheap electronics site.
The radio is only here to pick up the signal from the metal detector and turn it into a tone that can be heard.
Here is a list of pieces
Transistor bc547
Capacitors of one nanofarad 1n
Capacitor 4n7
Capacitor ten nanofarrad 10
Twenty-ohm resistance
resistance 47k
The coil are fifteen centimeters in diameter
The capacitor 47uF
Circuit breaker
batteri 9v
