It is known, dear brothers, that converting the radio into a metal detector is done by using a transistor to be a signal transmitter, and the radio can be used to receive the signal. Only the voltage and its parts are available, but today we are talking about a topic that I thought of in order to overcome the defects of instability in the first way, and therefore we need a signal transmitter other than the transistor.
Convert radio to metal detector using ic555
Since the ICSI 555, which is known as the timer, is a signal transmitter that we can control, I thought of sending a signal to the ground through a coil (coil) that is connected to the IC555 output, but first we must know what is the best signal to transmit, and in fact I thought of the same value as the signal sent by the transistor With a difference in shape.
Pieces required in this method:
a radio containing short wave or am wave
ic555 with its base (1)
Capacitor 104 number 2
capacitor 10 micro number 1
Resistors 390 ohm 1 number and 1 kilo resistance 1
transistor 2n3904 number 1
Shi'a (file)
5 volt battery
