CRYFTON .....

[Geo]

Hi.
Some friends sent me schematics from Cryfton OBMD.
Schematics are not so clear so i will draw them with eagle and after it will attach here.
Because i have n't many free time it is more easy for me to give at the end a part list.
For the time the basic is to see the members what is happening with this lrl who cost so much money and is a mix of schematics from Andy Flind, Alonso's PD etc.
If i know will give info but will not criticize it.
I have n't so hight knowledge level.
I suppose that the schematic that i am working on is the OBMD-2 because the other one that i have is a little simpler...
If anyone has any comments, can write here...


Regards:)

btw... is there any problem from admins????

[WM6]

Bravo Geo. You are most friendly man in our galaxy.


Regarding those Cryfton, it is big question why constructor need to go
complicated (or compilated) way, when we know, that it is more than
enough to attach simple calculator to kids pistol and make big business.

[Qiaozhi]

btw... is there any problem from admins????
It's ok as long as you don't post the manufacturer's original schematic.
Back-engineered schematics are allowed.

[Geo]

Thanks Qiaozhi.
Tomorrow i will have one version ready for upload.. :)

[Sneshko]

Thanks Qiaozhi.
Tomorrow i will have one version ready for upload.. :)

Bravo Geo! :)
Thanks in advance!

[Geo]

Problem with upload.....................
will try again.
The file is 62k and when upload it it is 157 bytes....:angry:

[Geo]

Here is the schematic of Cryfton. I don't know if it is obmd1 or obmd2.
If anybody knows can inform here.
Next days i will complete the part list and will attach here.

Enjoy it :lol::lol::lol:

[Sneshko]

BRAVO!!! :)
Thank You very much dear Geo! :)
Also, thanks in advance for the part list!

Part list next week. My opinion is that the IR iss doing NOTHING so you can find the value from other parts at Andy Flind thread.

[sakher]

thank you mr.Geo

[Geo]

Also i have another schematic (maybe the first) where there are some differences at IR section, all the rest are the same (preamplifier + Andy's MFD).
I will redraw it later.....


Also i have and newer schematics...... :lol::lol:

Longrangelocator's members love me and they give me any new schematic :lol:

:):)

[dragomir]

Geo, this is the scheme of OBMD - 1

[Geo]

Thanks Dragomir:).
So i have two versions of OBMD-1 and it miss me the OBMD-2.
Maybe a good friend to send it to me....

Hi Sneshko.
I post a photo from the coil of cryfton.
Do you see any circular coil or OO coils with critical null????
THere is only one square coil.... :lol::lol:

Regards:)

[dragomir]

Geo, is this an orginal device?

[abdou2014]

Thank you Geo. what is its inductance ?

[abdou2014]

Excuse me Geo, I did not follow your advice :)

...Аnd, Is this PCB from OMBD-1 or 2 ???
Thank you in advance for the answer!

Geo, is this an orginal device?

Yes, OBMD-1

[Geo]

Thank you Geo. what is its inductance ?

I don't know, not critical.
You wrap 30 turns and play with the capacitor

[Geo]

Ha, ha...! Very good Geo! :D
Thanks!

Sneshko

The pcb photo is the first pcb for OBMD1.
Constructor had attach to a Greek forum.
Look at top where is writes "antenna". It uses this track as antenna and this is what shows at schematic as coil with critical null :lol::lol::lol::lol:

[abdou2014]

Is it a coil stimulator, what are the values, can we know more about the IR sensor ?
Thank you !

[dragomir]

I feel like this infrared sensor is used to protect against opening the box.

[dragomir]

Geo, I did not see the second antenna in the picture

[GOLDEN LILLY]

The second antenna is not a coil, it is a in a form of a trace in the pcb(worded ANTENNA), it is connected to the input of the main coil via capacitor. This antenna is dependent on the PIR sensor. Look at the picture in the first page on this thread...
I have a complete schematic, pcb for this project...

[GOLDEN LILLY]

here is my project...this is based on the schematic posted in the forum...crypton clone.

Yes, you are right...:cool:

[abdou2014]

I need your help Geo !

[dragomir]

GOLDEN LILL Yhow is the role of the infrared sensor when it is enclosed in the box?

[Geo]

GOLDEN LILL Yhow is the role of the infrared sensor when it is enclosed in the box?

No role, it don't work.
IR there is only to make the device more complex and to be convincing that it works :lol:

:)

[Geo]

I need your help Geo !


I hear.....:shrug:

[dragomir]

It soon blocks the operation of the device when opened

[abdou2014]

The audio stage does not work, I think there is an error ???

[abdou2014]

Your circuit and the original are not the same, I need values of your circuit, thank you Geo!

[GOLDEN LILLY]

Of course it is not the same. The circuit drawn by Geo is a modification from the original circuit of Andy Flind. In the original circuit, the 4016 directly drives the buzzer but in the modification, the same 4016 drives a tone generator using 555 ic...

[GOLDEN LILLY]

The PIR sensor is not inside the enclosure it is positioned at the back of the unit facing towards the area to be detected. Even without the IR, the device will still function. I think the IR senses a slight change in the surrounding temperature. Take note that a metal buried near the surface absorbs heat from the sun during daylight. This maybe the reason why crypton will detect near surface buried metals at night.

[Geo]

Your circuit and the original are not the same, I need values of your circuit, thank you Geo!

The circuit is exactly the same.
4016 and 4066 are quad switch ICs, so no problem if you will use the 1st switch or 2nd etc....
The schematics have diference only at pins, nothing else:cool:.

IR is a trick, it don't do anything.
When you make a lrl with purpose to sell it then you try to protect it from copies (at least from amateurs). One way is to make it very complex. It is the recipe by Mineoro...:lol:
So works only one module (IF IT WORKS) all the other doing NOTHING.
The same here is happenng with IR.
The same is happening at Cryfton OBMD-3 with Ion detector and GOLD SENSOR etc...:lol:

:)

[abdou2014]

I check it's still wrong, when I approach the transmitter the LED lights up all alone, and when I get closer than the buzzer produces a weak sound .
I think it's not normal that the VU alone displays before (CA3130 + 4016 + NE555)
what do you mean by an error in this post Geo ?

Please show to us your experiment...

[Geo]

Dragomir constructed a very goog clone, i have two photos from it.
Dragomir if you would like i can post the photos here...

[dragomir]

Ok

[Geo]

I post here 2 photos from a OBMD1 constucted by Dragomir.

:)

[abdou2014]

I think the andreas preamp is less reliable :cool:

[abdou2014]

Very nice work Dragomir ;)

[GOLDEN LILLY]

Very nice...will it really work in the field?

[Geo]

I don't think :frown:
Before some years a friend gave me one oBMD1 for one week.
I went at some ancient places for test.
No one beep:angry:

[Geo]

Dragomir.. if you have other photos to post here send them to my email and i will resize and attach them here

[Sneshko]

Part list next week. My opinion is that the IR iss doing NOTHING so you can find the value from other parts at Andy Flind thread.

Dear Geo!
This week passes ... You promised Part List for the scheme you set ...
I do not want to offend you - I'm just a little impatient... :D :D :D

This project has been frozen for 6 years. The device is working in general, but I could not handle its settings. Can anyone tell me what frequency does the receiver and the induction oscillator work?

Sorry i am busy.
I started to write and did let it...
Today morning i updated the schematic with parts but only for IR section, beeper and preamplifier. All the other are the same from Andy Flind magnetic field detector. So maybe tomorrow i will check it again and will post it here....:)

What do you mean induction oscillator???

[abdou2014]

Mr Dragomir , can you detect magnet with your LRL ?

[GOLDEN LILLY]

There is no induction oscillator in crypton OBMD. It is purely a passive LRL...

[Geo]

There is no induction oscillator in crypton OBMD. It is purely a passive LRL...

I agree, this is the reason that i asked Dragomir...

[dragomir]

the infrared sensor controls the power supply of the IC7. IC7 acts as an excitation generator and is inductively mixed with the signal received by the receiving coil.

[abdou2014]

I think it's the mixing point between IR oscillator excitement and receiver ?

dragomir I had no answer ???

[dragomir]

The IR manages a transistor that turns on and off the power supply of IC7. The IR does not participate in any process. When the device box opens, it blocks the operation of the IC7 and the excitation generator stops working. This is probably done so that the principle of operation can not be traced when the device opens.

[dragomir]

abdou2014 i think this is the oscillating antenna but this is done for you in another way

[abdou2014]

Mr Dragomir , can you detect magnet with your LRL ?

[dragomir]

My LRL does not work because I do not know how to set it up. I remember detecting a 3-meter monitor, but it works only as a receiver without the excitation generator. now, if I remain free, I can experiment with it

[abdou2014]

At the beginning it is impossible to detect a magnet with coil 30, I detected it with only with solenoid coil. after the modifications I managed to detect it with the coil 30. but I do not know if this result proves that it is operational , I would like to have the opinion of Geo !

[Geo]

This project has been frozen for 6 years. The device is working in general, but I could not handle its settings. Can anyone tell me what frequency does the receiver and the induction oscillator work?

The device works at 68.5 Khz

[Geo]

The IR manages a transistor that turns on and off the power supply of IC7. The IR does not participate in any process. When the device box opens, it blocks the operation of the IC7 and the excitation generator stops working. This is probably done so that the principle of operation can not be traced when the device opens.

It is NOTHING.
If IR sensor receives signal then there are many methods to display it.
One simple is to drive a led.
Other is to driving the beep generator or to give the signal at input of 358 or to give it at input or to make an other one beep generator etc....
Here the constructor prefers to gives the signal at input with a most sophisticated technology method. He connected the output (555) to a antenna and try to excite the input coil. You must see only the coil for preamplifier input (30 turns) nothing else. Be sure for it:δροσερός:.

I don't know.
I never used a magnet to test a lrl.

[dragomir]

Thanks Geo. Does this device get a compass effect?

[Geo]

If i remember good i had compass effect when i had very hight gain (especially at preampl..)

[GOLDEN LILLY]

The two small coil wound in a wood former is not an excitation coil. It is used to add the inductance of the main coil. The small coil is connected parallel to the main coil. Adjusting the small coil distance in each winding makes a slight change of the total inductance but only in picofarad...It is like a capacitance trimmer to get the exact frequency...

[dragomir]

I think it's not. I think things are the same as Francoitali, but at a lower frequency

[nelson]

Hi Geo.
Since i stopped my attemps to fix my crypton obmd1 that i got from Andreas that never worked, i m asking you if we can exchange information to see if we can make it work.
Yes crypton has Andry flint circuit on it. Crypton at first time turned on, make beeps, but i notice that beeps were cycling and are we not stable, making me thing that the circuit i owned has some induced errors, because Andreas sold it to me has a demo unit.
Please lets talk by PM.

Hello Geo and thanks for your response.
Mmmm i have doubs if it really works, because lrlman hho also design tha arc geo logger, for it looks like a very serius and honest person. Mr Tim Williams, has made a few test with crypton and those test shows that it really worked for him. However, his devise is obmd2 and not a demo unit like the one i have.
When i get back to home, i will send you some exra information.

Don't have you any doubds... it don't work.
I tested it without results, also i have a friend that has it at his team but he did n't find something. Another friend has the OBMD3 baut no gold. Another member here has the OBMD3 but again without results. I have the Andy flind's mfd with all the adds and mods from Esteban but i had not success except some very small objects at mountain Olympus.

[GOLDEN LILLY]

So OBMD models are just expensive nonsense lrl...What about crypton PD of Andreas, is it also a nonsense lrl?

Other option is to buy expensive and totaly useless LRL from known fraudster.

Device that you build by yourself, even useless as LRL, can at least teach something about electronic and this way it come out as useful.

Hi Geo.
I agree with you. Crypton is just a waist of time and money.

About other devices and counting your expirience building lrl´s, is one of this devices really working? Wich one?

For my experience i think pdk was the closest device it seems to work and also Franco Italy device.

I nelson,
I have confirmed that my lrl works in different countries but at the same time it does not work for some members living in the same countries. You and also Geo are proof of this fact, certainly my lrl works in Greece. I can not give an answer to this fact, the only thing that comes to mind is that there is not enough amplification, in fact I noticed in my lrl that (for a weak signal) it is enough to decrease the threshold slightly to lose the signal. However, if you have the compass effect this guarantees that the gain is sufficient.

Best Regards

Hi Nelson.
I live at a City with "difficult" terain.
So Modified Mineoro FG80 works little at my City and good at other places
PDK don't work at my city but works at other cities, the same with Alonsos PD.
Andy Flind's MFD (or Cryfton...) don't work at my City and work a little at some places.
Franco's lrl works at my City with lower detection distance but it locates iron objects. Only one time i located copper and silver at test area. I have n't tried it at other Cities.
So what advice to give you??? Maybe to begin with the PDK if the terain at your area is good. About me i use 2 lrls with ferrite that are most better that everything else but they are very complex.

[abdou2014]

I think the best way is to work in infrared .

Is the two ferrite LRLs that you mentioned are Gold Gun ?

[Geo]

No.They are the No1 and 2 at photo here http://www.longrangelocators.com/forums/showpost.php?p=154651&postcount=5

Is it Andy flind modified or what ?

[Geo]

No, nothing similar.
At right from attached photo is the No2 lrl and at left is the pcb from No1 lrl.

[abdou2014]

good work :)

[Geo]

Thank you.
The right lrl detects all metals but the left (not the same but a modified version) only noble metals.
At left (normal version) the coil is wraped on a ferrite and there is n't the black coil at front of lrl.

[humhum]

Hi Geo, Which is No:1 and No:2 (with Discrimination ) and Maximum Detection from how much meter for big or small object ?

[Geo]

I have locate very big objects from 300m with the No1 and from 70m with No2.

[abdou2014]

it work in VLF ?

[Geo]

One of them yes (7.1 Khz) and the other at 130Khz.

[abdou2014]

you use them alone without a transmitter ?

[humhum]

I have locate very big objects from 300m with the No1 and from 70m with No2.

Ok Geo Good distance ,
Your two LRL Detect object with fast Moving from Left to Right or with very slowly Moving ?

[GOLDEN LILLY]

I guess slow sweep speed to catch the phenomenon...

Both with slow or medium motion but not quickly.

[humhum]

Ok Master , thanks . Maybe one PD is from Zahori + ...mod ;)

[GOLDEN LILLY]

Does anybody tried the Gold Zeus PD? How is this PD compared to OBMD?

[abdou2014]

what is the operating principle of your Battlefield laser detector , IR transmitter and HF or FM receiver or what ??

[dragomir]

My opinion that OBMD and similar devices work but not everywhere has the signal they have to capture, and this is related to the structure of the earth.

The hf receiver with the LC circuit,i dont know how this work but work :χαχαχα:

taxma, do you think that is right to post all the time irrelevant comments, in topics about specific detectors ?
Why you don't start a new thread about your cell-phone magnetometer, or your battlefield detector ?

hi Franco and thanjks for your response.

I was out of home for some vacation time and now i m just reading your post, that help me to continue with the project. So i apreciate your help and orientation about your free project.
When i finish a new pcb and mounting parts, i will start new test and of course i will share here my expirencies, to feedback all mambers on the forum.
Thanks and best regards

Nelson


I nelson,
I have confirmed that my lrl works in different countries but at the same time it does not work for some members living in the same countries. You and also Geo are proof of this fact, certainly my lrl works in Greece. I can not give an answer to this fact, the only thing that comes to mind is that there is not enough amplification, in fact I noticed in my lrl that (for a weak signal) it is enough to decrease the threshold slightly to lose the signal. However, if you have the compass effect this guarantees that the gain is sufficient.

Best Regards

Hi Geo. I just returning from my vacations.

So has i told Franco, i will restar building LRL proyects that i left for a while.
You are a very expirienced man about LRL´S, so your comments are apreciated.
For my was not easy to know at first time here on the forum, wich device was correct to build and study, because has you know many proyects and schematics where posted and also many builders has started to build units and tested normally with no success.
Indeed i goy one crypton unit from Andreas that never worked for me. But this risk was assumed by me, because it was one way to know who was the real honest man.

Today i can see more clearly that none of this devices works on all terrains or countris due to diferents field conditions. So for that, i can see now that may be some may was right and some not, depending on what they build, how they tune it up and where they tested.

I belive on Esteban devices, your devices and Franco lrl, because it shows that on the backup, was a complete interest to learn, experimenting and share information.

All and all, i will try againg my experiements, taking in mind that after all this learning years and expirences, today i have more knowing about the correct people that is keeping their work on lrs´s, without be interested on taking your money from your pocket.

Thansk Geo and will keep talking here on the forum.

Hi Nelson.
I live at a City with "difficult" terain.
So Modified Mineoro FG80 works little at my City and good at other places
PDK don't work at my city but works at other cities, the same with Alonsos PD.
Andy Flind's MFD (or Cryfton...) don't work at my City and work a little at some places.
Franco's lrl works at my City with lower detection distance but it locates iron objects. Only one time i located copper and silver at test area. I have n't tried it at other Cities.
So what advice to give you??? Maybe to begin with the PDK if the terain at your area is good. About me i use 2 lrls with ferrite that are most better that everything else but they are very complex.

I Nelson,

I would like it if you could make my lrl work. As I said it is necessary that the lrl is adjusted for maximum sensitivity and that this can be achieved without self-oscillation. It is useful to shield the box and the handle, when you grab with two hands the sensitivity increases considerably and this is a proof that the body intervenes in the revelation of the phenomenon. Another factor is the nature of the terrain and how long the test metal has been buried. In fact it could be that it takes several years for the phenomenon to appear. It would be useful to try the lrl in a real field (and hope that there is something buried for a long time).

Best Regards

Ok Franco, no problem and i agree with all what you said.
Let me finish this month and i will get into bussines againg
Thanks for your advices.

Geo, where are the components list of OBMD as you promised??? the circuit diagram you posted here is useless without them...

[jacob]

there is always difference between promising and do

[jacob]

very beautiful lrl is not like the number 1 that does not work or the number two that does not work or the number 3,4,5 also. its work I salute you

What do you mean? I don't understand your statement. I am only asking Geo for the component values of DC2008 based on the schematic he posted. As I understand, Geo keeps on promising and he never keeps his promise. So we never expect Geo to give us anything.Maybe he will only give selected members of this forum. That's what i think.

:lol::lol: maybe you have right... maybe not.
If will give all the data then some member maybe to ask for a ready lrl :lol:.
Also other members if will not have success with construction will say that i give false schematics... (i saw allof these all the years that i am at this forum).

Anyway... everybody is free to have his opinion!!

Hi All friends
anybody can send me this circuit component numbers?

Thank You

Hi Dear Morgan , may be this is Original OBMD-2 , without modification from You ,
But for works very stabill ( if OBMD-2 Sch is also or similar so like OBMD-1) , need ......... , You know What .

Hi Morgan
I remember well about crypton obmd1 . I had dummy target more than 5 years old . it is included 10cm x10cm 99.99 % coper . only some times had beeps.
But in other test crypton OBMD1 detect 70 years old target from 10 meter .
Morgan I saw your movies in youtube ,please show in movie Alonso PD , from how much distance can detect 1.5 volt batt, short circuit? . please use wire long 30 cm.
Regards .

1,5V spark

ALONSO PD, 60cm

OBMD-2 , 40 cm

PDK-2 ,2,20m

the spark distance only means sensitivity to that frequency, more important are the field tests.

My LRL made by my friend catches the spark 1.5v from 2.20 meters. But the TV from only 30 cm. I'm not electronic, but I can not explain, and I have no field to try it.

[Geo]

Battery spark is good test only for RF sniffer.
For all other methods ..... :nono::nono:
