How to make a homemade metal detector with a radio and calculator?

Creating a metal detector using a radio and a calculator is possible, but it will be very basic and may not be as effective as a dedicated metal detector. Here's a simple way you can try:

Materials needed:

A portable AM radio
A calculator
Insulated wire
Metal object
Battery
Steps:

Tune the AM radio to a frequency where you hear static noise.

Attach the insulated wire to the antenna of the radio and extend it out.

Connect the other end of the wire to one end of the calculator.

Turn on both the radio and calculator.
Place a metal object near the wire and move it around. You may observe changes in the static noise or interference on the radio when it comes close to the metal object.

This simple setup may help detect metal objects; however, the sensitivity and accuracy will be limited compared to commercial metal detectors. Remember, this is just a basic experiment and not a substitute for a proper metal detector..
