How to make a Metal Detector

[jaivk1802]

I want to make a metal detector(which must be relatively simple to understand) and i have also seen some techniques to make it(with a radio and a calculator) but i want to ask that is there any way that the metal detector can be made without using the AM radio and the calculator as a whole?
PS: I am asking this because i want the project to look genuine and completely homemade with no ready-made accessories

Please reply fast(I have to submit the project by 6th June)

Nice resource. Didn't know this idea has been stolen so many times. Looks like I may have found a new activity this weekend. Good luck with the project!
