Made my own Metal Detector and took it out for a spin!

[goldencoin]

Hello everyone

For the past few weeks, me and my physics class have been making metal detectors. We started by printing the circuit board design on the copper side of a circuit board. Then, we dipped them in acid to eat at the copper that was exposed. After drilling holes into it, we put various transistors, semiconductors, and other sciencey stuff. Afterwards, We built the coils by making three wooden circles, one smaller then the other two, then wrapping copper wire around the small one and gluing it all together. Additionally, we glued copper on it so it would not false when we moved it up an down.Then, we made a tuning device, a volume control, and a switch. Lastly, we held it all together with hot glue and tape. Nine people participated, one didn't bother to finish it, some didn't show up for the hunt, others fell apart or shorted out. Basically, mine and one other person's worked well enough for the hunt. My teacher buried around a hundred in dollar coins and quarters, plus some foreign coins. I found $37 in dollar coins, $19 in quarters (one dollar roll and the quarters were taped together), and a chocolate coin. Then I cleaned up with my DFX and was surprised to have only found nine remaining dollar coins and 4 foreign coins. Additionally, my sister showed up and used my detector to find three dollar coins.

Very Cool. Good job.

 

[Karinus]

Good job, sounds like you had fun.

 

[crazyjarhead]

You are doing better than me Nice job

 

[detector dave]

Now that is really cool!! I would have loved to make a metal detector in school. Great job and it goes to show you can find coins with any kind of a detector.

Hey, that's not fair, you found more with your homey than I did with my SE!

Great post! Maybe you should think about giving the Metal Detecting manus. a run for "their" money!

you guys rock, and your science teacher, well he rocks a lot. You should give him a plaque and a great big hurray for putting the class on this project. Plus he went out of pocket to fund the hunt. HE IS THE MAN, give him a pat on the back.

Great Project! It must have been alot of fun building that. Where did you get the information to do that? How deep does it go?

yep, he is a great teacher

That is so cool.

The closest thing I ever did to that (in high school) was making stupid little airplanes out of foam meat trays and seeing who's plane went the furthest.

All the directions were provided by my teacher, it does not go deep (4 inch max)

This story is absolutely outstanding. Not many people, myself included have the knowledge or talent to make a working detector. You must have one heck of a teacher. My hat is off to you. Great finds by the way.

 

[kg6yll]

This is what it's all about. I say put the kid on the BANNER!!!

[bootybay]

That is so very cool..I cant believe ya all did this... I see a big future for you young man. holey cow... am dumbfounded and you deserve banner on this one... the fact that YOU made a metal detector and IT WORKED... is BANNER worthy in my book.. so what say the rest of ya?

 

[juju]

I agree. Put this one in the banner.

 

[Colonial Zoyboy]

If you don't mind me asking, what VDI did the coins read at?

I wonder how many fellers in that picture now have the metal datecting fever? Well, we all know that at least one feller does. Goldencoin, you rock, bud, you rock!

Way to go. I am very impressed.

[DDEXPII]

I agree. Put this one in the banner.

[baspinall]

Sweeeeeet! I love it!

Banner Indeed

 

[Slipperyjack47]

That is incredible, You and your teacher are very inspiring and you should be proud of the work you have done. Not only was this a fun project but you have gained knowledge of the inner workings of a metal detector which many of us, including myself have no idea on. I agree whole heartedly that this is a Banner find!!!!!!!!!!!!!!!! Keep up the good work!
