Sheeesh where's the facepalm emoticon when you need it? how you can make 137 posts in this forum and not learn anything from it is beyond belief.
The comapny you have taken it to is robbing you if they want to charge $100. All the information needed to build both of these kits is on this forum, but you need the right equipment and knowledge to set them up. Have you even read through the build threads?

Problems with building a Silverdog Kit.

Dear Paku,

I have been making electronic kits since 1955. I worked as an electronics engineer for many years on computers and other equipment. I too, with my knowledge and owning several multimeters, Cap meters and other meters, as well as an Oscilloscope, must work VERY carefully when building a metal detector. About 2 years ago I built a Silverdog IGSL kit, it is still not working as well as it should, but I am waiting for the final changes that Davor appears to be working though.

You also need to build the search head coils very carefully, or buy a finished one.

I would say that building a GOOD WORKING metal detector is probably one of the most difficult projects for a hobbyist.......there are many, many things that can go wrong....

But my lack of success is not Silverfog's fault!!!!! Nor are your problems.

I personally feel you should apologize to him , here, publicly as soon as possible.......we do not need such rudeness.....

Also the company you are using are not the right people either, as mentioned elsewhere here, they appear to be:- "taking you for a ride!"

If you do not have the knowledge, experience and equipment to get your Metal Detector working all by yourself (with a bit of help from the other people online here of course!) , you would be better off selling the parts you have cheaply to someone with more knowledge and to add that money to the $150 you are paying that company and buy yourself a cheap but good finished metal detector. There are plenty around.

Beginners when building from kits mix up the parts by not reading the markings correctly. For example:- fitting a 100K resistor where a 1000K was required. They do the same with capacitors......I still always check each component using a meter to make sure I have picked the right one as its easy for ANYONE to make a mistake.

Just accidentally swapping ONLY two resistors over will mean your metal detector will be completely useless. Swapping over two caps can do the same.

You should be able to follow a PCB and compare it to the schematic correctly, before trying to build a kit, but you are obviously not that far yet. So you must persevere, not insult great members of these blogs......if what you said was even 1% true, I am sure that there would have been a lot more complaints about the kits, I remember none other than yours, so I feel you are the one who is "off base!"

Apologize to him.

Andy

its ok maybe im the loser one
but i dont want apologize
that becos i dont get any help fix the TGSL kit From silverdog if i get the fix
i will apologize

If you were able to send the TGSL kit to me, and pay the return postage, I would get it working free-of charge. Unfortunately I fear the shipping costs would be too great between Malaysia and the UK.

You may have noticed that many people have had problems with an even simpler design (the Surf-PI) and trying to help fix it via the forum is a major task when that person does not have access to an oscilloscope. I fixed one recently for another member, and the problem was caused by 4 resistors being fitted in the wrong place, and one faulty IC. It would have been extremely difficult to debug remotely, even with a scope.

I don't think there's anything wrong with attempting to build a kit without a basic knowledge of electronics, as everyone has to start at the bottom at some time, but you shouldn't blame the innocent when things don't work out as you expected. Building a metal detector is not something an electronics beginner should attempt if they have limited experience. Have you read "Inside the METAL DETECTOR"? This will help you to understand some basic concepts of how metal detectors work.

why do not you just keep on trying to teach how to repair the damage
why to show my offense right
why are you all mad when I say cheat
is it really cheating
and you just abuse the referee all right
and not help to correct what he should be right Correct

Can you post a picture of your idx board?
That would help a lot.

Is it possible you have an IDX board with the short circuit on? you need to look at the IDX thread here ( http://www.geotech1.com/forums/showt...PRO-VDI/page54) and check your board carefully.

[Qiaozhi]

why do not you just keep on trying to teach how to repair the damage

Because even my patience is not infinite, and eventually [if the process goes on too long] I just simply lose the will to live.

why are you all mad when I say cheat

The answer is simple. You are accusing Silverdog of cheating people out of their money by selling kits that do not work. In reality, Silverdog is providing a valuable service to Geotech members with very reasonable prices. Many people here are more than satisfied with the kits they receive.

Also, you previously said "My Friend Have Make IDX PRO From Silverdog IT IS Working Nice Target and i have buy 2 kit from silverdog idx pro and TGSL its Very Nice Detector bro".
So the question is, why don't you ask your friend for help? You know the kit works OK (you've said that yourself), so how can you say that Silverdog is cheating his customers? That's why everyone here is unhappy with your response to the problem you're having. The kit is not at fault.

Looking at your youtube video, the overall build quality looks good. However, as an inexperienced metal detector builder, you should start off using a commercial coil , and not try to build your own. It just adds too many variables to the equation.

have post the picture the board dont have trimpot dont have 3 Diode

you can see the board from silverdog picture http://www.silverdog.co.uk/shop/imag...t-1024x768.jpg

that its not same like there ar post to me

[gtdavid]

post a picture of YOUR board..
i will look at it and compare with my board that works..

Hello Paku. Sounds like you had not read the entire thread. Clearly, in this version missing trimpot diodes and there are also different values of resistance in the control sensitivity in other versions.There are three or four versions of Eduardo's circuit! (Which is different from White's original diagram) and each of us tried the different settings (or new ones) to make the IDX work to our personal taste.
I personally chose the Silverdog PCB configuration (though my PCB is made in house) and everything works fine.

Post some good pictures of your board and your coil and so surely the most advanced forum members can help you (if there IS a solution for your problem)

Regards,

Fabian

yes i have found the short circuit on that thraed

PCB from silverdog. It is short circuit X and Y signal
