www.adventuresw... Make your own coil for your metal detector! Sure, you could always BUY a new coil, but what if the size or type you want isn't made for your model...then what?
Coil building is a fun way to not just expand the possibilities of your machine, but to get a deeper understanding of why things do what they do.
And oh yeah....disclaimers...not responsible for you fucking up your machine! Read though and carefully test everything before plugging in a DIY coil!!
COOL , Loved it , can't wait till part 2
I love your videos, always interesting to watch
Good DIY video. looking forward to Pt.2!!
Waiing with interest for the test!
In case anyone is curious, degaussing coils are used in CRT monitors for the following reasons...
A CRT monitor uses an electron "gun" that fires a stream of electrons from the rear of the picture tube (the pointy bit) towards the front (the flat, or slightly curved) bit. Coils on both sides as well as on top and bottom are fed current in precisely timed pulses and act like electromagnets. This bends the election stream and allows the stream to "scan" the screen.
The electron stream travels through a metal screen full of tiny holes to let the electrons through where they finally hit the inside of the front of the tube which is coated in a fluorescing coating which lights up when hit by the electrons. By lighting up (or not) various pixels, the picture is created.
If a magnetic source is brought into proximity with the monitor, it may magnetise certain areas of the metal screen that sits just behind the front of the tube. This causes a localised and permanent distortion to the picture as the electrons are deflected as they pass through the screen.
The degaussing coil creates an alternating magnetic field designed to demagnetise the metal screen and thus prevent this distortion.
Pretty simple really, just takes a long time to explain.
TL;DR - A part of the picture tube can become magnetised which distorts the picture. The degaussing coil demagnifies that part thus preventing or repairing that distortion.
That monitor wire is there for discharging the crt to ground when turned off its like a big capacitor holding thousands of volts ..reason you did not die scrapping the monitor...now thats another good reason you like that wire !
great idea for a bid jimmerz, will tune in for part 2
love your vids. They are very entertaining and informative. keep up the good work
I"m up north filling Kerosene Heaters.....
Cool freaking video man, can't wait for part 2 !!
Keep @ it and HH !!
Great stuff Jim, suspenseful day waiting for Part 2 and the big test, love the technical stuff, didn't understand any of it - but doesnt matter. Hey, and maybe get up early, mow the lawn and annoy the neighbours - a complete day. (I'm not saying your lawn needs cutting LOL). HH mate.
Jim! I'm still waiting for the next day when you'll finish this coil!!! its been 10 years.
😂😂
Hopefully by the time I finish feeding the sled dogs, and chopping up firewood for the wood stove, you'll be done part 2!
Do not tape the coil. Soak it in shellac to keep it mechanically stable and therefore minimise electrical drift. The Faraday shield needs a gap in the foil not a S/C. This is for receive side only. Ground the shield. This is for electrostatic shielding. Not necessary for a well designed detector and it will reduce the effectiveness of the coil a little.. So many varying parameters in this area. Use a good DB scope and power up the TX coil then look at the received signal. Coil positioning will be ultra critical for best results. Hope this is of some help. Nice video. Keep it up.
You are a funny guy , i'm just at 1:36 and got a big smile on my face!
damn i hate waiting for the next day : / .. looks interesting!
up north lol Im your neighbor man. Bama man here =P Love the vids keep em coming
Ok thankyou, ill go have a look.
Excellent video lol will herb help in construction 😊
building now....thanks.
Love the USMail tape. All you need now is a stamp.
Tune in tomorrow and watch me lick stamps all day long.
me hace acordar a unos muñecos,de los locos del once.
no, but lots of info out there on "Bounty Hunter" metal detector, schematics and plans, some other varieties too. easy to build. Also check national geographic store, they made an RC tector already...low quality but maybe you could build on it's designs and make a good one!
I know everyone seems to be thinking bigger , of course but I am wondering how to make a "Pistol Probe" type detector. Any ideas? I am anxious to see part two on you r coil. Thanks.
Jim I love your Videos, I was wondering if you could do a step by step video and build a super duper metal detectors pin pointer please :)
Good job! So where is part II?
Hey Jim pick me up a bag of weed off your neighbor! Bring it with ya next time you come to Coshocton ! Nice mini coil ! You might wanna use the coil to check your neighbors for weapons too! Good show as always bro! lol!
Hey there, im working on building a remote control tracked vehicle for my electronics project. Im incorporating a metal detector on the front of it as its purpose is to detect metals buried underground. I don't suppose you have any written plans or blueprints i could possibly refer to when building ? Thanks.
Man,that is cool! Hope you also make a 20" coil.We can discriminate the Chinese army helmets out!
question: I have a whole roll of copper wire i took out from my "no good" circular saw last month.though i dont know if it's wrapped in nylon or not.it's pure copper to me! can i use IT for a good coil? or does it need to be magnetic copper wire?
ok,i just tore out the exact same thing from an old pc monitor,nicley taped up thin copper wire.What's the diff between that and the copper i tore from a non usable circular saw? circular saw copper wire is 4xs thicker but not coated with any tape.can i still use it?
"Fucking neighbors" lol I hate noisy fucking neighbors
I know this is an old video but any chance you can do an updated version where you make the coil from scratch and showing the 3 lines of wire and what each is for? thanks :)
I have massively upgraded my ideas since this brutal fail of a video...there is an insanely cool way to build a metal detector, but life keeps getting in the way of my hair brained inventions. Hopefully soon!
How can I make my trans/recv. be more in tune with gold? I am a prospector.
Me gustaria entender tu idioma sin embargo comprendi la mayoria solo que no se cuantas vueltas se dieron en la primera y despues en la segunda.Muchas gracias por enceñarme.
Excuse my stupidity but is it possible to use such a self-made coil with an E-Trac (Minelab) and would it really work adequately?
can you make an EMP
how bout a BLT for when you're done? ;)
*****Metal Detecting DIY: make your own coil part I*****
Hi, I try to make a BFO, its working but not on the ground, its always beeping, is this normal? i already make faraday shield aluminium foil and conect the end to the ground, nothing change. HELP!!
+Arief B which one did you build? there are several different designs.
+Adventures with Jim
From this one:www.easytreasure.co.uk/bfo.htm
All ia work, not on the ground, tiles and wall...
I found a site where the villagers found some gold piece near ruined temple.
there is no such thing as "magnetic copper" it's simply what they call thin, epoxy or resin coated wire used to make coils. test the conductivity of your wire, see if it's raw copper or just red paint. if it's raw, no good for most coil apps, needs to be coated.
....its a bit late ...but I just came across those plugs ....fairly cheap
{Flange Form GX20-4 Aviation Connector Plugs Round Flat Head 20mm Dia] = ebay
No, but I'm working on an SBD...you know for grocery store lines and shit.
keep one eye out for those next door i think their metal detecting is when your not home !
dang its " Dean Friedman "
hi jim iam form ireland and geting into detecting can u make me one and send to ireland i have 18ct gold diamond ring ill give you that
Is a ace 250 a good beginers detector..
Thank you
Yes
Is the 350 worth the extra bucks,..?
Or is one as the other..?
Mike S I have never owned one before.
How difficult is not to spend all day finding tabs off cans or cans and such..?
What is my fear I can figure out its use so I can not find trash with it..?
The 350...Ace.?
Little more but is it worth the extra cash..?
Thank you
Mike S Sounds like wisdom thank you..
Mike S I going to get one...God willing..
My uncles from the older days.
When they were young the found a flat rock stone what ever.
but on its back side was a map in spanish.
They couldnt figure it out so they broke the rock into both having a piece..
When I was younger I seen one half of it.
But it was old really old looking even then worn down..?
It needs insulated wire the wire you use is not suitable
wrong. this wire is insulated, designed exactly for creating electromagnets. this video failed on a variety of other levels, but thanks for playing anyways.
Go to school. Magnet wire is not thin copper! That's just a tinning.
@garbageguru1 ahahahaahahahahaha! no 20" models but I do have plans for a 12" that *should* be awesome and a 2-box conversion kit for off the shelf detectors...should be able to dig to China with that one.
Very small coil, small coil in a small dtection
that hair
You look like a homeless - homo dude!! u should cut your hair man!
