My TOTeM project

[Dell Winders]

As I've said many times before, I have no problem with anyone wanting to experiment with all-electronic LRLs, Any experiment is a good one.

Why should anyone care if you don't have a problem with people experimenting with just all-electronic LRL's? Who do you think you are? Dell

Are you worried that LRL experimenters, encouraged by this forum, may discover something you'd rather they didn't know?

Hi mustetfa

Good work for your PCB

But we like some details for your LRL. If it possible

[Nicolas]

Type of other Lrl detectors

hi
do you share this pd all file
thanks

Hi dear Mohamad look this quote from Qiaozhi you can understand that

See Chapter 14 ->
Inside the METAL DETECTOR - Published September 2012

[Nicolas]

The difference between the two TOTeM units is probably in the coils. Even at 9.5V I was able to adjust the ferrite so that iron was rejected, and the only problem was the meter being offset from zero. I suspect your ferrite coil may be closer to the TX frequency than my unit.

Here's a suggestion:
On page 224 (TX Circuit) it is mentioned that R21 (10k) could be replaced with a multi-turn preset in series with a 4k7 resistor. This will allow the TX frequency to be adjusted, which will then change the sensitivity. If you do this test with a new set of batteries, and make the TX adjustment so that the meter does not have an offset away from zero, then the voltage regulator may not be required. Alternatively you could add both the regulator and the TX adjustment preset for greater flexibility.

Hi Dear Master Qiaozhi

Is that you solve the problem ? for the totem works in all countries of the world.

Maybe you're right for your setting.

I also 2 years before I encounter this problem. but I solve this problem . I found a good method to cancel the effect of the compass.

I suggested a frequency that varies between 30 to 75 kHz adjustable to calibrate LRL in any region of the world in a split second if this problem is encountered .

Dear Morgan I am with you when you go down on the earth to locate a treasure fled the frequency goes completely .
Directory you can watch here is my little video with a mobile phone by a friend during our experiences of my LRL .

look here is 59KHZ and Goes 1KHZ and 0KHZ when touch Ground

But in compass rest and also increases

Note: I am against the electronic swivel but my friends think otherwise hihihih
but even as it rotates. this is a first experience for 3 years beginning

Thus a buyer of my LRL has found gold and silver together in a tomb . a near distance a bit long 600 m and a depth of 1.80 m

Dear Qiaozhi to help Goldmaxx to cancel the detection of the compass using a capacitive or resistive potentiometer to find the right frequency in his country.

I do not know his country to help . because I can define the frequency by my caluculs . and the experience of my buyers LRL . I want to thank Williams for his LRlman table definition of frequencies .

And thanks for FrancoItaly for their attention to the effect of the compass. but it must neutralize adjustment of frequency.

Waiting for your good news dear Goldmaxx

HI
HOW ARE YOU SIR?
DO YOU HAVE TOTEM PD PCB FILE IN PROTEL OR PROTEUS FORMAT???
THANKS
I AM WAITING YOUR ANSWER IN FORUM

Hi mohamadder

Sorry, but I have only the book “Inside the METAL DETECTOR” from Qiaozhi.
It includes all the details to build a TOTeM PD. I can only recommend this book.
I am a LRLnewbie and have learned a lot about LRL with the book from Carl and Qiaozhi.
Of course, I am experimenting further with the TOTeM.

Check out the thread from Sneshko that he could publish something from the book

Here is the link

Hi Nicolas

I have made some small modifications to the TOTeM, but I can not test the device properly.
The problem is that I need a target (phenomenon) in order to locate it and to calibrate the device after that. I have done many tests on places, where what could be, but all without success.
I also think that, as you have already written, the problem is together with the right frequency in my country.
For this reason, I've built up from a few months ago, a small test field and buried silver coins. I hope that in a few months is build a small "phenomenon" that I can calibrate a LRL and locate it.

Now it is winter by us and I can not make any tests outdoors. But I still have some projects, that I want to build and test them in the summer.


Best regards to all

Hi Mustefa Thank you.

Here is your PCB

Hi mustetfa

Good work for your PCB

But we like some details for your LRL. If it possible

good question

[Fred]

Hi Mustefa Thank you.
Here is your PCB

Hi Nicolas,
You noticed the problems on this pcb ?
Just to call you attention.

Hi Nicolas,
You noticed the problems on this pcb ?
Just to call you attention.

Yes my friend thanks I have said that to Our friend Mustefa for correction.

and I have a lot of PCB and I have to check all.

[Fred]

Exactly
Good work !

[mustefa ubram]

hi nicolas and other freinds
I've looked pcb.pcb is correct.The problem is related to printing pcb.You have prepared in the traditional way
