thank you very much MR.Qiaozhi

[sakher]

Please can you explain the passive\active switch (pl1 and pl5)
how Connecting with the DPDT type ?
thank you Qiaozhi ..

[zakari]

hi my dear qiaozhi

thanks alot for great job

best regard

[Mike(Mont)]

Thanks for posting. Not that I'd buy one but curious why you don't sell the completed boards, etc. as a partial kit? That way it would be easy enough to modify to get the thing to work without having to spend how many hours for us "slow" types.

[Guard]

The last 3 weeks i am searching for information to build your project.
That was ... "the right timming". :)

Thank you so much Mr Qiaozhi.

Look at this thread ->
http://www.longrangelocators.com/forums/showthread.php?t=18771&highlight=TOTeM
where Goldmaxx did an excellent job of following the instructions. There are also several videos of TOTeM in operation.

Snesko made a PCB for TOTeM, but he posted the files on an off-site server, and these files have since been removed.

I will leave the design of a PCB to members of the LRL Forum. This project is now in the public domain, and hence it's up to you what you do with it.

[Mike(Mont)]

Thanks.

[Mike(Mont)]

Just so you know. I am not agreeing with some of your "conclusions". I'll leave it at that. Of course most say I am unconventional.

[d4rkh00d]

Thanks a lot Qioazhi

[Mike(Mont)]

Q,
I did enjoy reading about the ferrite rod, etc. I've said it before there is something about the ferrite rod I swear it pulls the signal in--makes a pathway for the signal to travel on. In the past I have used the tin can and string telephone analogy.

Something like what happens with the solar wind at times,what they call a magnetic superhighway. I'm not saying there are particles, just the magnetics. So, yeah, I don't know what i am talking about, but there is something. Like they say, when you get outside of the crowd you can see from a different viewpoint. For sure, I have the outside part down real good. :lol:

[Mike(Mont)]

Curious about the ferrite rod iron rejection. I have not experienced this with my contraption, just like to know about the cause of this problem. Someone on the forum asked me about this so I offered to help them.

[Mike(Mont)]

No problem, don't bother. Whoever asked me, I do not trust them. :nono:

Hello guys,

I just wonder to where this jumper (in red circle) connected?

[Qiaozhi]

Hello guys,

I just wonder to where this jumper (in red circle) connected?
On the schematic it shows only one connection from U3 pin 1 to LED1. I think this may have been left over from tests made during development of TOTeM, and it's no longer required.

[AurumKid]

Is it OK to replace CA3240 with LM1458?

[Qiaozhi]

Is it OK to replace CA3240 with LM1458?
The pinout is identical, and there's no special reason for using a CA3240.
So the answer is "yes".

I see that you've managed eventually to register ok, so welcome to the forum. :thumb:
At first I thought you might be a spammer who was trying to register with multiple fake email addresses, but it appears that there was some other problem.

Well done on duplicating the TOTeM project. I notice that you have modified the design somewhat, and included a DVM on the front panel. Is this something you would like to share with the forum, since this is an open-source project?

My mail was not fake, your activation link comes with a little delay.
I called my Pd as PD-GoldZeus. It not only has DVM, but also includes some internal changes.

[HaFar2010]

Hello
Dear All
Yesterday, i received a video from one of my clients.
In the video, there is an ancient hill and he is able to hunt a valuable point (buried gold).
You can see the video in https://youtu.be/UjlO-dL98BQ.

[liudengyuand]

This circuit is a little messy, and who can turn it into a complete circuit diagram?

[HaFar2010]

Hello
Dear all.
Some time that several questions have engaged my mind and i haven't a clear answer for them.
So i decided to share the questions in the forum, and ask you to consult together.
the questions is as follows:

1- What is the quickest trick for producing magnetic field of gold? How long does the trick take?

2- As you know, PD has reaction than power flow, TV and low-power light.
So question that rises here is that which of them is the best test for PD?
Other words, which of the tests has most similar to gold?

3- Why does all LRL, which work base on ferrite, has reaction than low-power light?

[liudengyuand]

Cooperate type LRL, only to the alternating magnetic field has received effect, such as high voltage alternating current (ac), transformer, switch power supply, radiation, electric spark, mobile phones, etc., it is no response to constant magnetic fields, such as a huge magnet, it is induced, buried metal, it is impossible to produce alternating magnetic field, even if it is a little inherent magnetic force, but the earth's magnetic field is much bigger than it is, so is unable to detect LRL, because a huge magnet is greater than buried metal magnetic field couldn't detect tens of thousands of times, so my advice to you is, can play, don't expect too much it can give you find any metal, even if you go to waste dump, buried inside a lot of metal, it is unable to detect, video about BBS that are false, because they do not have a video for the metal, the compass effect, study a lot of people all over the world, so far, not a true feasible LRL machine, just many profiteers in hype

[abdou2014]

Is the magnetic field of a television set constant ?

[HaFar2010]

Hello
Dear all
we have done a test for detection of a freshly ring. In the text, the machine is able to detect the gold in 20 cm distance.
You can download the video from the follow link.
Please share your opinion.

Hello
Dear All.

We again received another video from PD-GoldZeus.
In the video, the operator initially detects a probably point.
After second checking, he finally digs it and gets out a buried gold.
You can see the video from following link:

The machine in the middle of the ring a few times, then take out a thing, a machine to detect, the lowest level of lies, only weak-minded people will go to the letter,

[HaFar2010]

You're in a big mistake!
The first two videos have taken at different angle.
Please see it again attentively!

[liudengyuand]

I have no mistake, your video is not to respond to a metal, can't prove it to the role of the metal, dig out because you don't have the metal

[HaFar2010]

Since the law of his country has restrictions on digging and detecting burid golds,
it led him to take this video at night.

PD can closely detect new metal. For discrimination, you must find null line. check your digital meter.
If your pd has been created correctly, number of the meter is decreased when you close it to ferrous metal (iron rejection) !

Hello guys,

I couldn't find any Meter 250uA (full scale) 675 ohms here in my place... is there any other alternative to replace this meter? Can we replace it with digital meter or a 10 LED indicator. I'm not an expert on electronics but i can only follow instructions on how to build. Any help or suggestions is much appreciated.


Thank you.

Thank you.
Note that D1 limits the voltage across the "meter + R24" combination to 0.7V. Without R4, the current through the meter would be: 0.7V / 675 = 1.04mA. This is clearly too high for the 250uA meter. Hence R24 (3k) is used to limit the maximum current to: 0.7 / (3k + 675) = 190uA. The slightly lower then 250uA value stops the meter needle banging against the meter stop when a large signal is received.

All you need to do is replace R24 with a suitable value for your meter. Let's say (for example) your meter is 100uA full-scale deflection (FSD) with 1k5 resistance. A total resistance of 0.7V / 100uA = 7k. Hence, R24 needs to be 7k - 1k5 = 5k5 (or slightly higher). A simple solution would be to replace R24 with a 10k multi-turn preset, and manually adjust it to suit your particular meter.

It should also be obvious that your chosen meter needs to have an FSD of less than 1.04mA.

Hi HaFar2010, I See in Video that PD of your clien Detect buried metal without moving PD from Left to Right or Right to Left , my question is with How Method works it. (Ferite+Magnet etc...or ...).

[HaFar2010]

Hello
Dear All.

According to my previous posts,
my first PD has great successes
because my clients not only sent me their successes and feedbacks
from different countries, but also they proposed me several suggestions.
After analyzing the feedback and much effort, finally my new TOTEM PD is ready!
the version has a special package and higher sensitivity to gold!
Circuit of the PD is TOTEM, but I did a small change inside it in order to getting high stability.
You can see the pd in following link:

Nice job Zakari, shares the layout file pls. what are TX RX frequencies ?

[Mike(Mont)]

I was thinking of building a ToTeM and not too excited about using the strip board. Poor eyesight (cataracts) is the main reason. I have a pair of those binocular magnifiers but not good enough. Even a magnifying loupe I can't see it. So my thoughts were to try to build on just a perfboard and follow the schematic "map" not the computer generated component placement. This way I will have more space between the connections so less chance of shorting. Is there anything I need to be warned about before attempting this?

Or if anyone has a PCB they are selling?

[Mike(Mont)]

Actually i was thinking about copying this PCB format and just use perfboard and wires on the bottom of the board for the traces (scroll down the page a ways to post #212). That way it will look nice and clean--FROM THE TOP SIDE! LOL Rats nest underneath.

HAPPY NEW YEAR everyone. I hope your projects go good this year and that everyone hits a good one.

As for the ToTeM project, I guess I don't need anyone's help. This one is going to be a gamble because I'm going to hack the thing. And I'm not totally against a hand-held, just want to keep it away from my face and belly. So maybe it will end up like one of those devices they wheel around on a cart.

Well, my horoscope said to rev my engine because victory is at hand this year. Maybe they meant I am DUE for a good find. "Overdue" is more like it. LOL :D That's what I call a catch-all phrase or safe bet. LOL I guess I could write horoscopes, too!

[Mike(Mont)]

Pahom, thanks for your reply and encouragement. The Contraption seems to work as is but I just need to find out if the ToTeM receiver will work better (actually some sort of hybrid). Honestly that computer generated stripboard looks like near impossible for my eyesight and somewhat shaky soldering technique. I lost count of how many jumpers on that board, nearly 70, so times two that is a lot of soldering right there. I'd never get it working because the strip board peels apart when doing repairs, at least at my skill level. I wish somebody had a PCB to sell, but for now this project is just experimentation so I don't care how pretty it doesn't look. :D

[abdou2014]

I want to know about the people who built the TOTEM, if it detect a spark of a battery 1.5V and at what distance ?

[abdou2014]

nice news abdu bro .. that's mean's with your modification The device has become very sensitive !

yes my friend , and it detect also a bip from clock every one second !

[abdou2014]

it's not just a question of sensitivity , i removed the comparator , it's a fast pulse extender and display !

[Qiaozhi]

TOTeM is capable of detecting the spark from a 1.5V battery several meters away (not just 1.5 meters). Also, an old style CRT television can be detected from 6 meters.

[abdou2014]

did you detect the battery spark several meters away with or without the transmitter or stimulator ?

At first my Totem does not detect the spark, and when I change the comparator and the audio, I have succeeded !

[Qiaozhi]

Spark detection does not require the transmitter to be operational. You can detect it in passive mode.

Do you think that Heathkit's sensitivity is comparable with the circuit receiver that you have made for the totem pd? I would like to build the heathkit with the omega coil system but by using your circuit. The only doubt i have is the fact that heathkit has a regenerative feedback and i am not sure if the opamp solution can reach heathkit's sensitivity. What is your opinion?

The Heathkit GD348 detector is very old and not very sensitive, even with its 10" coil.

It is also important that you understand TOTeM is an experimental PD designed to investigate the claims of LRL proponents, and that there is no accepted scientific theory to back up any claims for this type of device. It's main purpose is to give you an opportunity to explore the pseudo-scientific world of LRLs, and make up your own mind on the matter.

Thank you my friend! I am also a sceptical experimenter as i have built a ton of LRL's the last 10 years. But i always wanted to put a finger on Alonso's pd, and your circuit looks perfect for that. Simple and reliable.

There are no PCB details.

[Mt724]

Although Edition 1 of Inside the METAL DETECTOR (ITMD) has been completely sold out for several months, we still receive requests directly from people who are interested in Chapter 14 (The Pistol Detector).

Therefore, as an early end-of-year present from the administrators of this forum (and authors of Inside the METAL DETECTOR) we hereby release complete details of the TOTeM project from Edition 1.

Enjoy!
Ok, thanks

Sch V1.19 have several errors.
Tuning of this LRL is very-very difficult. I don't recommend building.
Thats all.

Hi brother, is there any version of this pistol that you recommend with no circuit errors?


Thank you

The schematic you're referring to (V1.19) is for the Alonso Pistol Detector. There are no errors in the schematic, but there are a lot of unknowns regarding the setup.


Note that this thread is for the TOTeM Pistol Detector, and all the details are in post#1. TOTeM is not difficult to tune, and there are no errors.


If you want to discuss the Alonso PDK, then please start a new thread.

wrong thread sorry

It seems that this device can be operated for infrared detection. Make the transmitting circuit independent and put a variable resistor to facilitate changing the frequency until it matches the resonance of the receiving unit. It seems that it is possible to balance the coils on a single ferrite in some way while reducing the transmission power of the coil. I'm not sure, unfortunately I didn't make the device. I try to simplify it for amateurs and get rid of unnecessary accessories that will pose a problem for some.

Merhaba ?mer

So how will this happen?
TX and RX will work on the same ferrite. How to connect IR RX?
Is there a way to remotely detect when the tx coil is vibrating?
We need an explanation for those who don't know

[omar]

Unfortunately, my friend, I do not know why I tried the device, but I found praise for its work. See the attached video. I think it is a commercial version of the device. They found a way to set the files to one fret and the device became physically decent. His work has not changed and he discovers new and old metal. The method of adjusting the coils and resonance frequency is the most difficult in the device, as it determines its operation and the metals with which it will interact. It seems to be a mixture between a metal detector and a radio, I don't know.

okay omar

There is a sound analysis program for androids called Spectroid, listen to your ferritin and look at the result (of course, a phone is required) you will understand how much our measuring instruments are misleading us.
Then think about the resonance-related dimensions of the ferrite length. Why couldn't we find this program before?

[folharin]

I had built the totem! but it didn't achieve good results.. I hope that with the modifications it will be really effective!!

[omar]

I have improved the drawing a little and got rid of the connections. You may need to shield the sensing stage. It appears that the transmitting coil and the receiving coil are capacitively coupled to operate at one frequency, and thus this process increases the sensitivity to the resonant frequency. You may need to raise the value of the variable resistance to facilitate the adjustment process. Anyway, as you know, nothing is guaranteed in this field .

The drawing I present is one-sided. Perhaps this post will help you, my friend, and help others. It contains useful information about this device.

You're welcome. Good luck

You're welcome. Good luck

hello omar
I made an application suitable for your project but with pcb holes. I could not solve the LED situation. It seems to work. There is detection as the tx power is reduced and the frequencies change. It is a workshop environment, not a natural environment.

[omar]

Frankly, this modification needs the support of someone who has successfully tried the device with a similar modification. For example, how much transmission power is appropriate for capacitively coupling the coils with the ability to balance and adjust the threshold. Is shielding the sensing phase binding? What is the correct direction of the current in the two coils? presented to you the idea and the path others took in developing it, and it seems that they succeeded in the operation process. Now it's up to you to try it. I hope that whoever succeeds with this amendment will help the rest of the members.

hello Omar imade this TOTEM but its prduce the 65khrz frequincy but i cant balance tx and rx its work with sparks need some one show as by vedio how to balance it imade:https://youtu.be/9xdu1eedKZk

Hi

does the totem really work in practice as a long range.. Has anyone discovered old metal with the totem?
there isn't any report totem work as long range

[abdou2014]

must change the TX circuit

[aft_72005]

must change the TX circuit

totem TX without problem .. why transmitter must change ?

Hello my friend .
Anyone who wants to try this device.
First, he must make a receiving circuit with only the receiving coil and test the device according to the operating instructions in the file attached to the first post in this topic, such as sensing the electric spark... etc. After making sure your device works very well and there are no problems or errors in assembly or parts. You go to the second step, which is manufacturing the transmission circuit and adding it to the receiver. I do not advise anyone to manufacture this device, but there are people who want to try this device (for them I am providing this information) to help them and make things easier for them and to make the appearance of the device more dynamic and acceptable. Because I think something useful can come out of this device. I will post pictures and links explaining my idea regarding the device?s narrow-band antenna. And manufacturing methods.

I wish everyone good luck and thank you

[aft_72005]

Hi omar
yes , i agree with your opinion . but i remember my experiments for some years ago Tx and Rx on ferrite couldn't act as long range.

[aft_72005]

may be designer of totem had feedbacks from people that built and trying totem .

thanks Omar this one is defrent than TeTOM in this one RX and TX are in one frett road
and how long the freet road in this one.?.
in last tow day
i make ready the circuit

[Anwar2]

thanks how to delet this message

[omar]

I apologize to you, my friend Anwar.
I did not understand your problem. I placed the drawing files open so that members could change as desired. The device does not accept calibration. You may need to flip the transmission coil (change the direction of the field), or the transmission power is high and needs to be reduced and the resistance value increased by 1 K.

[omar]

Don't worry, my friend Anwar. I know the amount of effort it takes to create a device manually, the challenges with this type of device, and the disappointment when it does not work the first time. Or even when it works and its feasibility is discovered much less than expected, it is hope that makes us try and try. I wish you success in your life and abundant livelihood.

[Anwar2]

how to connet the test point I think with press switch and Ground

[omar]

This frequency measuring point is connected to an external device called a frequency meter. To adjust the transmitter frequency

thanks Omar between RX there is acapacitor on the PCB What value of that

[omar]

Capacitor value with coil inductance. Determined by the frequency at which you will operate. I advise you to use the original transmission scheme, as its value is set to 65 kHz. Especially if you are using the original version. Note that not all 555 timers provide a stable frequency depending on the quality of manufacturing.

[Qiaozhi]

BC108 or BC107 ... it doesn't matter.
Any general purpose NPN transistor will work.
You could also use a 2N3904.
