    Has anyone ever made their own metal detector?

    I've found many "How to" videos on YouTube.

    Yes, with coat hangers. It's called dowsing and can be used for water detecting also.

    If all your finding is pull tabs, bottle caps and beer cans, I've already been there.

    I started detecting in 1968 with a detector kit built in electronics class.

    I have my college students build a simple metal detecting circuit on breadboards then wind a coil and pass metal objects across its face (remember they are learning circuit theory). They can watch the waveform change on the O-scope. I believe in demonstrating simple circuits that can show real world solutions to interesting problems.

    IMO: Now for real metal detecting purchasing a machine from a quality company is what you should do if you want to get into the hobby.

    What a grand thing to do. Metal detectors are great for teaching circuits as they can encompass magnetics, analog, digital, audio, and visual responses. I wish I had been involved in detector design back when I was an undergrad teaching the EE labs at FSU, would have been so much more interesting.

    Actually yes....There once was a kit you could buy from the Sears/JCPenny Christmas catalog....I cannot remember the name since I was around 7 or so...I also built a lie detector with it....And a lot of other things....It MAY have been what got me into all this junk...lol

    Actually yes! Every now and then an electronics magazine would produce an issue with a how to build a metal detector article. I built two of these from different articles and they worked, no discrimination but they found all metals in the ground, depth was not that great and they were crude.

    I then purchased a Heath Kit metal detector kit and assembled it. It also worked, found all metals in the ground, had no discrimination, looked a lot nicer than the ones I'd built from the E magazines but again no discrimination.

    I would suggest you purchase a used machine, one that has a reputation of being a good machine but is outdated, likely it will have a bunch of adjustment knobs and switches on its box surface, a speaker, an analog indicating needle and meter face and it will work. With some experimenting and learning you will learn how to set the machine up for a basic mode (all metal, no filters), be waving the coil over the ground and by resetting the knobs and switches in sequence you will know what type of metal is under your coin with about 85% certainty. (this would be like a Whites 6000d coinmaster - likely somewhere around $100.00) Old school but it works and will be Way Better than any magazine built detector. IMHO............63bkpkr

    Note: One issue with purchasing any used detector to look out for/ask about is battery damage! If the batteries ever rotted in the battery box, stay away from the machine! Worse case is the rot also got to the circuit board, rotary switches, toggle switches and that is like the kiss of death!
