I translated forum by altavista I think they write Schema is not correct.
Maybe KT315 can help about this subject

Hi Erol,

This is not a schematic of the Nexus.

Yes i downloaded schematic and pcb from this link.
Already made it and it is ready for final tests. But only dont know values of R50 and R51?
Also in schematic 317 is noted, while on pcb some other kind of stabilisator is used. Never mind, pcb is drawn so suitable that ordinary 78xx can be soldered there without changing anything. Another mistake is transistor BD139 also noted as BC639...I put BD139, more logical to be there.
Also few components omited from pcb; some resistors arround pots. not a big deal at all. Intend to draw very small piggy pcb with pots and those omited components.
On that link they talked a lot about 317 and other things, but i do not understand Russian at all so i am not really awared about they talked???
No, i dont think this is Nexus, but never mind, schematic looks interesting enough to try it. Also that video is interesting.
I am constantly searching for good non motion vlf. Do have hopes this will be the one that suits me...or maybe not.
Only KT315 here can really solve those questions, but he is rare visitor here, latelly..? Why KT315?
So, ok, if somebody know those resistors values, c'mon and say here.
Otherwise i would experiment and probably have a lot of problems as usuall...

Hello
I can guess only , k maybe 1 you have to ask kt315 for true

Thanks Erol, but neither of those has simillar oscillator. No help.
KT315 is showing only ocassionaly here. I dont think he will come here soon.
So i am pushed to experiment.
Buah!

Altavista translation from RU forum

(need your further translation, but may be helpful)


code name since I do not know source - I think Folk it will prompt.
the idea of diagram is obvious - simplicity. [diskrim] - your eyes. i.e. switchman and his indication. a feeling on the maximum. any metal reveals moreover. which is still must…

Into what good convert on TL317, and I earlier thought this [krenka] ordinary. It is necessary to take for the armament.

This yes:. convert there that must
But still, it is possible to take for the armament the brilliant method of including the transistor of direct conductivity Q4, with which at the output never it will be sound. (BD139 - transistor of reverse conductivity.).

TL317- the [obynkavennyy] regulator. What here new? But that transistor is included on entirely correctly. Emitter always on larger + base always on smaller +, i.e., it is always opened. As soon as difference will fall to what that of level, less than 05V so it will be locked. And sound then (!) it will disappear. But it will not always be absent. But is here with the nourishment here what the [lazha]… here and all. The emitter follower at the input complete [lazha]. All disturbances from the nourishment will be at the input of amplifier. Emitter Q9 sits in no way there where it it must sit… On the whole these are not diagram, but simple grenade be casten by whom the… for which the… [nafiga] is that…
[Pitalovo] will be here actual +-4V, rest will eat up regulator. These are [och] small [pitalovo]. As for this [shemki].

The base of Tr Q4 sits on plus (but this for the straight transistor the earth) and it is fixed.
The emitter of straight transistor also sits on plus. Therefore, on the collector it will not be current. Passage C-E of Q4 will be it is always located in the break.

TL317- the [obynkavennyy] regulator. What here new? What does mean usual? In the diagram the small battery of 12 volts, and at the output two [naprugi] +11 and -11 and midpoint 0.

of course not, maestro. Base that on + but this + = 4V and on the emitter from the battery directly… i.e. it [plyusee] considerably. Difference on the base exists, it means current it will be. I.e. sound is fed to the regulator. There is indicated +Bat

Then it is understandable, if [napruga] of those is plus different. Here let they will designate precisely on the battery that very point “+ BAT”. But at the same time also +12 will rename in”+ BAT ", surely.
And will be replaced BD139 by BD140. gentlemen are artists, the fabulists

Then it is understandable, if [napruga] I replace BD139 by BD140. gentlemen are artists, the fabulists
This diagram or is not successfully copied or simply humor on the theme. The first, and the second by itself left in my opinion.

I do not know, to you certainly be seen, but impression such, as if this diagram no one [vzhivuyu] and made. Purely paper engineering. Moreover it seems that [infa] of [idet] as from the owner, connecting diagram and coils. If someone made this diagram, then it would be executed as its native and three times licked. Without single [lyapy], with respect for reading and itself. And they already at least inquired by the TL317ym, such as in it housing before it sketching.


TL317 occurs also in this housing ([umoshchnennyy] version), and here are coils, so I would make [dubl]D, than this “eight” to pull with itself But “[bylo]/[nebylo]” is made [vzhivuyu] - this theme not [sushchevstvovalo], if was immediately lined [fotka] of the assembled signet or, at least, its figure

With [izminenii] of the form of coil from the circle to the ellipsis will change only the inductance (it will fall) and the quality (also it will fall) that in principle not what it will not influence. Diagram in effect there will be the same. I see no reason in this the schematic of coils.

Uh...as i understood they claims that this is intentionally faked schematic and also values on pcb....
Blah...blah..blah...and pretty rough translation.
Ok at least now i do know what to do;
i will take this and toss in garbage for good.
Russian, bugarian and turkish schematics are far history for me, from now on!
Also russian, bulgarian and turkish schematics,projects,hints,tips and datas are TO BE TAKEN WITH LOT OF DOUBTS in future. Why? Simply 90% of those turned to be faked (intentionally) so far.
I can stand here and claim that i made relly a lot of hanmades so far. Relly huge number. Also NEITHER of one workables was from russian,bulgarian and turkish schematics. Neither one!? How come!?
So far i tried 4-5 from those to make and all was bogus and intentionally faked!
From now one they simply do not exist for me.
All workable schematics came to me from my Dutch friends, few Germans and few Americans or British.
So...this "statistics" simply will define my further trust and type of people i will cooperate and share with in future.
Regards!

ivconic, you are right! do not cooperate and do not share what you have with us!!! we have what we have and we give what we have! you will always get all info from us, even it would be a truth or not. BUT if you HAVE NOT a good filter in your head you CAN NOT filtered the info. then I am SORRY! then I can help you nothing! good doc is able to help you in any case!

[kt315]

why you so unhesitatingly think the internet MUST give you all 100% of honest information if you do not want give only 1% him?!
try to give all of yourselves on all 100! and - MAYBE! - internet will agree to give you this 1%! internet PROMISES NOTHING and you know good it.

[ivconic]

KT315 just look what you posted here???

First, if somebody looking you here for help - you are not showing. Or you are showing here just to add some unuseable comment latelly.
Nio benefits from your posts latelly at all.
As i remember, it was simillar in the past. You gave here half informations and for other half you expected money! Is that what you use this forum???
Not fair.

[ivconic]

why you so unhesitatingly think the internet MUST give you all 100% of honest information if you do not want give only 1% him?!
try to give all of yourselves on all 100! and - MAYBE! - internet will agree to give you this 1%! internet PROMISES NOTHING and you know good it.

Internet MUST NOT "give" me 100% accurate informations, but registrated members of this forum MUST! And i will repeat - MUST! Same as i MUST give them back only ACCURATE informations.
Otherwise this forum and membership doesn't make any sense!

I gave here only 1% ....??????!!!!! Shame on you KT315! Shame on you much!

Because of the people like yourself i am thinking not to post here any more...
I already made very nice friendships here with several nice people. I dont need forum to exchange with those. I can share and exchange by mail.

I never asked money for schematic like YOU DID!
You are SHAME of RUSSIAN people! You and frauds like yourself!
You think you are smart? By giving faked schematics and later "blackmaling" for money here. You are missusing this nice forum by advertising some Grozdas, Mozdas,Dickas,Pussas and simillar russian garbage already known as very bad copies of western metal detectors.
You think you have brain?
You think you know something in electronic?
I DONT THINK SO!
Good bye for you!

[ivconic]

BTW, i still remember Jackdetect's words upon you:
"..do not consider KT315 as serious e.e. So as i noticed he is electronic ignorant only use to advertise somebody's else handmades...i intend somehow to skip KT 315 and directly contact that russian e.e. who is real maker of those few detectors that really can be used with minor mods..."
At the time i didnt understood Jackdetect's words well, now i do.
