i have so much respect for people like you who not only do amazing things, and with your free time create useful resourceful tools that you will later put to use. but you even take the time to show others how to do the same. everyone is complaining about not having a job and here you are making your own equipment and going and making a job, thank you man this is just too awesome. you are awsome

@bobjo1006 Год назад

youve been such a scientific help and i loved doing the quiz even tho it was like 2 am for me when i did it

@marketingformoney 10 лет назад

Hi Frederick, great video. I have built 4 of the Silverdog boards so far. Here is a tip that will help folks get up and running quicker. Just wash the solder side of the board when you finish soldering. Do this before you populate the board. first with alcohol or a proper solvent then with warm soapy water. A small stiff bristle brush like a toothbrush works great. make sure you dry the board completely prior to powering up .The 7660 chip is very sensitive to flux residue and washing gets rid of it.

@tobymulder1015 3 года назад

Dude best video I have ever seen, thank you! You've just made crawl behind my desk and soldering and 3d printing for the next week 😂

@GoldfindersAu 3 года назад

Thanks Toby

@martinrochejocquelein1772 3 года назад

It would be nice to 3d print the coil casing..you can get a water prove container....all you need do is place the coil onto the shell and snap together.. You can plastic weld the snap together shell or glue it. The bolt of the shell to connect it to the handle can be made from plastic as well on the 3d printer..now connect the shell to the handle..you can also make a mounting shell making it water proof..

@crobulari2328 10 лет назад

After a lot of experimentation with a DB scope and pulse generator I settled for 20 Turn coil of 1mm wire Dia. 100 ohm damping resistor. I sampled after 30, 60 and 90 microseconds switcheable with secondary sampling at I believe it was 300 microseconds after the end of each pulse. (long time ago). Pulse transistor was at the time a TIP42. Receiver used was an analog devices AD507 IC which was much faster than the old 709`s used at the time. I don`t remember the slew rate offhand but it was fast. Pulse rate I used was either 50 or 200 PPS. The audio generator was a gated Oscillator running at a comfortable audio frequency . VCO`s are horrid to listen to. Power supply rails were regulated. Result ... an excellent PI machine powerful and ultra stable. Coils were 8", 12" and a large 16"diameter one. I loaned it to someone and you can guess the rest. Just thought that this may be helpful to someone.

@GoldfindersAu 10 лет назад

Sounds good careful not to overload the circuit by using 1 mm dia wire

@efgenios 10 лет назад

Being an electronics tech myself, I found this whole video very interesting and cool.... One thing I have not been able to find in these types of videos, is how does one adjust (or find) the null point on a DD coil... I am about to make a coil just for experimental reasons and dont know how the nulling is done. If anyone knows, I would appreciate the info.... (having said all that, I do own a proper detector, a Minelab Explorer of course and im about to buy the next model, the E-Track which seems better... ive also got five different sized coils from the small 5 inch to the 15 inch WOT.... )

@GoldfindersAu 10 лет назад

I dont know, but experimentation is what i use

@efgenios 10 лет назад

Ok, thanks... just after I wrote this, I found something on an italian video, he uses an oscilloscope to null it... but I cant understand a word he says.... LOL...

@1evio1 10 лет назад

loved your video, could you use a metal detector coil cover for your mold? you could fill it with your resin with the two end wires out then when the resin gets cured you could add clay to make a mold for the two brackets on top of your new coil mold and fill them with resin to hold your pole. Do you think that would work?

@GoldfindersAu 10 лет назад

I dont see why not

@tolgakarabulut8287 2 года назад

Good morning and thank you for this valuable information and I have a question please exists on this . _( How many turns are in the grand mono coil _18 inch _ and wire diameter user (gpx 5000) _and how it is linked the wires in numbers? ...my respects

@GoldfindersAu 2 года назад

the thickness of wires and turns are to suit resistance of the coil only. Powerful magnetic fields can be created using one turn only, but the circuit will fail, burn out or not work well.

@workinalday4351 7 лет назад

Hello, I see that you added the .45 insulated wire, thank you for that. Can you tell us how many loops you made with the wire, and what is the diameter of the loop itself? Having the size of the loop and how many times you wrapped the wire around will be very helpful. Thanks again, great video.

@GoldfindersAu 7 лет назад

I used .5 at 22 turns and 8 inch diameter, but .45 at 25 turns and 9 inch with a slight elliptical shape should work better. however i found the hard part to be getting the the circuit to work.

@JosephMassimino 4 года назад

@@GoldfindersAu In the USA the wire comes in gauge, and the closest in mm in diameter was 53 gauge, which is ,49 circular Mils nominal. So when you say .45, I found nothing, so give the inductance of the coil, and that will be a good starting point as I can measure inductance.

@eddiegorden 10 лет назад

Frederick, thanks for the videos you have posted and all the information. I am interested in building a detector, but would like to find a source to get a board already built. In other words I would like to get a kit that basically have to assemble. Do you have any suggestions?

@GoldfindersAu 10 лет назад

I have considerd this and concluded that they take me too long to get the board to work 100 percent and they fail with the slightest mistake. my brother is more tec savy than me and he can get them to perform, but he wont help me anymore. so yes it is a tricky project but they can perform well in salty environments and low mineralisation

@wiggymccrackin8240 3 года назад

Quick question...if I added more copper wire for the coil, would that allow me to get a stronger signal???? If not, what will adding extra wire do? And how would I get a stronger signal???

@GoldfindersAu 3 года назад

There is a limit what is optimal, but more importantly the whole coil can't weigh more than 300 grams or it becomes tiring to use after an hour or so

@kawamoko75 11 лет назад

Hi mate confuse on diy coil,how do I calculate coil turn on 0.25mm copper wire ,any instruction for the calculation

@jasonwitt8619 5 лет назад

That is the same thing I'm trying to figure out. I have all the wire needed and the detector is an Garrett AT gold but I want to make a larger DD coil myself. How would I know how many turns to do on each side of the coil. Because each side has different size wire. One is 32 AWG Gauge wire and the other is 25 or 28 AWG Gauge wire?

@tipstricksss1453 5 лет назад

How about making a coil to go inside of a boot for a stealth metal detector? That be pretty cool. Is there anyway to add gain to a small coil with more than one coil?

@tipstricksss1453 5 лет назад

I thinking more of the yagi antenna design but putting that concept into a small coil, so on a yagi antenna you'd add more elements to get more gain so I was thinking maybe that might work with a small coil by adding more coils to get a more powerful coil.

@GoldfindersAu 5 лет назад

Nice idea but the coils would have to alternate ,i thinkl

@goldfinderspragmaticvideos. 5 лет назад

Like most mid range Pulse Induction Metal Detectors, it will detect a can at 12 inches in the most difficult salt and mineralisation,- a Gold ring at 8 inches max. The really expensive Metal Detectors made in USA like the Whites TDI now days will double that performance.

@GoldfindersAu 5 лет назад

Even then the coil needs to be much larger.

Every Detector is different. Only the designer knows what will work best.

@greggpearson2785 9 лет назад

Hey Frederick, in this video when you tested the loop you used 4 batteries. In part 1 when you make the housing etc you have 2 x 3 battery packs?? What were the voltages of the 2 x 3 batteries? Are you sure that loop is 11 inch or 28 cm? I cant find a painters bucket that large the largest I found was 10 inch or 25.5 cm. Great videos by the way. You have made me want to make the Surf PI as well.

@GoldfindersAu 9 лет назад

Gregg Pearson Double up on power, not volts. dont excede the 13 volts from li ion batteries.Around 8 inch mark for round coil is great for most applications

@greggpearson2785 9 лет назад

Frederick Barnes Thanks for the info, I noticed in your latest batch of videos you've stopped using the Surf PI?? or is it because you tried it under water when it leaked, did it not work after that? Hope you have a great New Year and thanks again for the videos.

@ChristopherJones16 9 лет назад

At 14:26 you said you "used hot melt glue and carved _____ stuck on to the bottom of the bucket" what did you say there? Timber? Just wondering how you were able to carve deep slots in the bucket for the bracket when te bottom of the bucket doesn't seem that thick. So I'm guessing you cut two rectangular holes and then created some kind of cavity to attach to those holes so the melted plastic has somewhere to go. For the hole for the cable. You said to use silicone. Not sure what you mean there but wouldn't using like a pen case in that hole suffice for when you pour the plastic into the mold? That is if the pen case too is non-stick like the bucket plastic.

Frederick Barnes look online for how to make the surf pi 2.1.the coil used there is better for salt and normal ground.

@crobulari2328 10 лет назад

Hi, Do NOT cover your coil with foil. This idea was used by some manufacturers for their BFO machines as a Faraday shield. Not a complete shield but with a say 10mm gap in it and connected to 0V or ground. This is not required and must not be fitted to a PI coil. Not in my book anyway.

@greggpearson2785 9 лет назад

Crobular I I tried the Faraday shield on my PI before setting in fibreglass. Didn't do a thing on mine, hehe excuse the pun.

@MrAndreapas79 4 года назад

@dresoul5600 7 лет назад

Ingenious! Quick question, is it advisable to waterproof my stock coil with a rubber liquid spray such as Perma-Seal?

@GoldfindersAu 7 лет назад

No , Dirt will stick to it. Usually the only part that lets water in is where the wire comes out ,but if you damage a stock coil you will most likely have to buy a new one.

@JosephMassimino 4 года назад

Also, if you get rubber between the wires, it will add capacitance to the coil, and may not work as you want as a detector.

Thanks for the reply Frederick, and thanks for the compliment. It did take a lot of trial and error! I'll try some thinner foil. I've currently got my ~8 inch coil detecting just over 6 inches. Trying to get a little deeper. Took a ton of tuning, I thought it was broken at first, but it seriously took 20+ turns on each dial before it got a signal

@ChristopherJones16 9 лет назад

What's a surf pi? A metal detector? Or is that like a raspberry pi board?

@ralphroc 9 лет назад

It's a Pulse Induction circuit, search "surf P.I." on google and you'll find the maker selling out of Europe. It's basically a kit for building the brains of a metal detector, and then you need to build your coil, etc like Frederick's video. It's a tough circuit to build, minimal instructions, and a lot of small soldering to do, but if you can make it, you'll have a $1,000+ detector for a fraction of the cost ($150-200)

Frederick Barnes i based that comment in work of a guy named Joseph Newman he had a giant spinning magnet powered by allot of 9v bat in series, high voltage and from what i understood of his work, the more wire u have of smaller gauge, more u can increase the voltage and bigger is the magnetic field. i'm not sure if i got the thing right.

Is there any reason that you cannot purchase a professionally made detector loop and use that instead of making your own? Is there anything about the electronics or any other parts that would make that a problem? The casting, etc. seems like a huge hassle to me. I'm confident with the electronics and the shaft/handle/etc. but the casting, while I'm sure I could manage it eventually, seems like a hell of a lot of work.

Frederick Barnes Actually, after pricing professional coils, I am reconsidering making my own. Most largish coils are $300+. Way too much. Hassle or not, I'm going to need to mold my own. Is there any reason why I could not use a small diameter (say 18-20mm) flexible PVC pipe filled with araldite or hot glue to make a circular enclosure for the coil and then glue some braces in a + pattern up/down and side/side to it in order to keep the geometry from distorting and to provide a mounting point for the pole? Or, how about cutting off all but the bottom 10-15mm of a 300mm diameter plastic bucket, placing the coil into the shallow "dish" that results, placing the coil and then just drenching the entire thing with hot glue, araldite, or some similar waterproof adhesive? Oh, I see that that is exactly what you have done. Is it compulsory to mold the mounts and cut out areas in one piece or can you simply glue them to the coil enclosure later? Apart from being light, waterproof & rigid is there anything else that needs to be considered? On a related note, how do you prevent water, dirt and/or sand from getting in via the hole left for the plug connecting the coil to the cable? Seems like an obvious point of intrusion. Thanks.

@tvsinesperanto7446 8 лет назад

Oh I almost forgot, what are you using to cast the coil enclosure? Is it proper molding material as used by artists/sculptors, etc. or are you just using large quantities of araldite or something?

@GoldfindersAu 8 лет назад

araldite is best cos it wont shatter

@tvsinesperanto7446 8 лет назад

Holy crap, really? How much did you have to use? That's a hell of a lot of araldite. Do you think casting material would work instead, for example this stuff: www.bunnings.com.au/diggers-500g-cast-and-embedding-resin_p1874117 Or is all casting material prone to shattering?

@stuartoneill2663 5 лет назад

The more wire you use the stronger the detecting ?

@GoldfindersAu 5 лет назад

The coil becomes heavy, and no better results

Can you give us a link of the metal detector circuit if you are not allowed to show us. Thanks.

@samommar 7 лет назад

I have questions please? what is the best for wide range thik coil or thin coil? or what is reason for a wide range and deabth?

@GoldfindersAu 7 лет назад

Thin and light is best,- no more than 300 grams 8 diameter works best on coin size objects.

@samommar 7 лет назад

Does it work good with the rocks?

@GoldfindersAu 7 лет назад

Better than most

Hello! How is wire gauge? And how many turn you do? Thank you :)

@GoldfindersAu 5 лет назад

.45 wire 22 turns is close to being right. i used .5 to save time.. not enough wire will burn out the board however

@frankm9328 5 лет назад

Thank you!

@OG96932 10 лет назад

how much turns did you use for you coil and how what is the width

@GoldfindersAu 10 лет назад

20 turns at .5

@user-pt3jj5nq6m 9 лет назад

how much turns did you use for you coil and how what is the width thank you

@GoldfindersAu 9 лет назад

احمد عبد العاطى i used 22 turns with .5 insulated copper wire 8 in diameter. but you can use .45 so long as you dont use too little as the resistance can damage the circuit

Frederick Barnes Hello Mister Frederick first thank you for Alrdaly my question and secondly Aezrny errors in the language because I unto thee by Google Translate and I hope to visit us in our city Alascndar and see the beautiful beaches Alascndar please Sidi I want to know what is the perimeter SEARCH COILS and you very much

@robinrwilsonsauls 9 лет назад

Frederick Barnes If you went in and out of the nails-as you were making your coil-would that distort your signal-and for the last few rounds could you rope the copper around the circle? In Wires/Cords the signal is boosted by going around the strands-that is why I was asking.

@GoldfindersAu 9 лет назад

Robin Sauls i will try that in my next experiment

@Munzer1977 2 года назад

@briandelanis7348 8 лет назад

Is there a factory metal detector that you would consider similar to yours?

@GoldfindersAu 8 лет назад

There are various pulse induction detectors around. these are used to power through salt or mineralised Gold fields. they are expensive however. CS4pi by c scope is similar in power but it cant operate well outside salt water.

@briandelanis7348 8 лет назад

Thank you. I have watched your build videos, you put alot of effort into them. I appreciate that it gives me more confidence to try this. I dont think a $1500 plus store bought detector is in my immediate future. Thanks again

@GoldfindersAu 8 лет назад

Difficult to master water hunting, but if you find a spot where heavy items gather you can get a good return

@numisaccent6723 9 лет назад

can thicker wire be used for the coil?

@GoldfindersAu 9 лет назад

Numisaccent You would have to use a lot of it, otherwhise it will burn out components on the board.

I have found that the best coil is made with a generous application of paypal ;)

@GPCTM 5 лет назад

what if the coil was made of Ag (silver) wire instead of Cu (copper)?

@GoldfindersAu 5 лет назад

Very little energy loss through the coil and with a more efficient battery life i think.

@GoldfindersAu 11 лет назад

See part 1

@kenny444tourist4 9 лет назад

More. buy a none working coil, cut the bottom out, build coil in top and use a cover as a base. :-)

Could I buy a Minelab X-terra 6" or 10 x 5" coil on ebay and then build the rest?

@GoldfindersAu 8 лет назад

Coils are matched to the circuit, chances are it will destroy the circuit or not work well. There is a possibility that it will work well,- but the circuit is tricky to build or repair

@worldwidemetaldetecting8034 10 лет назад

i was just curious, because there isnt many coil's for my metal detector as i need a big one, is it possible to use a same KHZ coil as the machine, aslong i transform the coil connector anyone?

@GoldfindersAu 10 лет назад

I dont know but i dont like your chances of unwinding a specialy made coil it in theory should work with new same length same size wire and less turns larger diameter tip-By broken one and reverse engineer it remember you loose sensitivity on smaller objects if you do go bigger i am not an expert but
