CRYFTON .....

[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 !

The device works at 68.5 Khz

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.

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..)

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

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.
Regards
Nelson

If anybody knows can inform here.
Next days i will complete the part list and will attach here.

Enjoy it

[abdou2014]

have you made any changes ?

[Geo]

Hi .
The member BRS inform me that there is error at schematic near to audio generator 4016.
After check i found the errors., so i attach here the edited schematic.

BRS.. thank you

Hi Nelson, how are you.
I believe that this lrl can't give good results but if you want sent me an email and we can see for any solution.

Regards

[GOLDEN LILLY]

OBMD 1 may be good but the newer model may be better...Anyone who has the schematic of the new model? I am referring to OBMD 2 or 3.

[Geo]

Another one Fraud....

[nelson]

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.
Regards

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?

[Geo]

Another Fraud....

[taxma1981]

Thr long distance detector don t work perfekt and every day,i can find treasure only with a magnetometer now:χαχαχα:the time is precious

[Geo]

Who asked you how you can find treasures???
And why are you laughing ?? Are you dumbfounded??
If you have something to write about Cryfton write it here otherway open a new thread and write there how you can find treasures.

[taxma1981]

You are the fool who hurt the world with the useless schematics:Π

[WM6]

Schematics that Geo posted here are free and that is a big difference.

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.

Yes, I am fool because I present free schematics of fraud commercial constructions to protect the members. Yes, I am fool because I am giving the opportunity through the free schematics to see the members who are hiding in these scams. Does not matter, keep going with your wisdom and let me go with my craziness.

[taxma1981]

if this circuit works, he would put the project on a common view;

this Mr only blames others, has ever made his own and shared it with other people here;?

it's wrong, we're not here to learn electronics or to waste our time and money, this forum is called (longrangelocators)
