I need Digital Mdf project

[wtrk]

Hey all.
Some of my friends have a project works with brass rod.
There are 12 type of selection unit ( gold,silver,metal, hole or void etc. )
2 brass rods putting inside the ground and people take another L brass pod , walking around this device.

I think some signals are sending and receiving between L pods and device pods.
Can anyone see or done this kind of Mdf

You can buy a cheap signal generator for under $30. Battery operated. Just remember it is 80% operator skill and knowledge. And that is assuming you have everything correct and know what you are supposed to know and have good locating conditions. They've been around since the 1980's. Nobody even wants to talk about them any more. Dell Winders, one of the pioneers in MFD, quit selling them. Said they don't work reliably any more. His advice is don't buy one.

Thanks for your answer.
Bu t some of my friend use this and they said definitely work..
I would like to create my own, if I find project files.

According to me; you mean " dont buy it or use " right ?

[Mike(Mont)]

I didn't say they don't work. If you want my advice (not likely LOL) get a cheap one and see if you can get it to work. People use a cheap one and sell it for high price. I suspect you already.

Im a newbie in electronic and interested in treausre more than 8 years.
After that I want to make my own device and I saw some device.

I want to make " which is I explained before " that kind of device.
So ; If I buy a signal generator
1- Can I set with programming some value of that device. for example
Gold 2000-5000hz
Silver 5100-6000hz
Metal 7000-80000hz
Void 700-800hz

like this ?
Is that possible ?

I dont know how can I programming hex

[Mike(Mont)]

No, no. You buy a cheap frequency generator, read the instructions and just use the keypad to enter the frequency you want to use. The controls don't work worth crap on those cheap ones.

You might look at the Eliminator e-120 at imagelocators.com The euro is low price now.

could you please show me some of them ?
A few friends diverted me here, and they said I can get help here..

You can build your own MFD here ->
http://www.geotech1.com/cgi-bin/page...mfd1/index.dat
Guaranteed to work as least as well as any MFD on the market.

Thank you Qiaozhi.
After I done this project, can some one help make this digital??

[Mike(Mont)]

Yeah, you can build Carl's and probably sell them for a thousand bucks.

Is there any digital type of this mdf project ?
It could be difficult to set frequency settings.

[Mike(Mont)]

I don't understand why you want to reinvent the wheel. If you can't locate how do you expect to get it right? Did you look at the Eliminator e-120?

[Mike(Mont)]

Why are you trying to put a hex on somebody? This ain't witchcraft.

[Mike(Mont)]

I guess nobody has a sense of humor around here.

[wtrk]

I think analog system settings are more difficult than digital system.
I just want to do it this ;
for example
1- Gold ( 500hz - 1500hz )
2-Silver ( 1500hz - 2500hz )
3-Void ( 2500hz - 3500hz )
4-Brass ( 3500hz - 5000hz )

after I done it, I want to choose some time gold mode, some time void mode etc..
It could be easier for me.
I dont want to reinvent wheels.
Could you please help me ?

[Mike(Mont)]

I guess i don't understand. You put up a range of frequencies. Are you trying to sweep through these? I've never known anyone to do that. MFD uses one specific frequency like 8.7 KHz for silver. Possibly you might adjust that one way or the other like 8.6 KHz. It takes some time for the frequency to lock on what they call phase loop lock. If you are constantly changing the frequency this will not happen.

Hmm..
Not constantly changing.
For example : X place I just set void mode and will look for void. 1 hour later I will set gold signal frequency and will look gold..

Is that possible ?

maybe Im a new in electronic and cant explain what I want. sorry

[Mike(Mont)]

I already told you that's what a frequency generator does. Your brain is locked.

Gold : 5.25 khz
Silver : 8.95 khz
Lead : 4.25 khz
Void : 700 hz

Hi this is our digital MFD not MDF that mean

Magnetic frequency detector and other Synonyms hhhhh

Hey I didnt find something the link.
So, I want to make, 1st picture left place located kind of MFD.
It looks fine

Hi it's work both together the 1st left is for ground the second work same rods.

Do you sell it or defining to make it

Dear it is for sell is commercial not for free project

We have a problem to buy something here..
Prices more than 70 euro or 70 $, we have to go to gate and should pay %18 tax.

So I should make it myself..
