Hi, I want to build a metal detector for my liquor store. So I have embarked on gathering the components I need. I wanted to know if you guys could help me with suggestions. What do I need to have for this project?

You will need a circuit design before you can choose components. What sorts of designs (or theories of operation) are you considering?

I'm looking to build a basic beat-frequency metal detector.

Google will reveal many designs and detailed construction tutorials for that type of metal detector.

Alright. Thanks.
