Bulgarian 'PULSE STAR' (... close to Legendary one)

Hi

Hi Mr. KT3 ..

Can we make this detector detect gold only by justify the pulse frequency as the Gold frequency ...

sorry my English is not good enough ....

Hello Georgi and everyone,
Thanx for quick responses..i am allmost trough but i have few more questions:

1) ""From the Trimmer strenght from the schematic wich are multiturn and wich are potentiometers? Example: RV1= multi RV2= multi.....RV6=Pot ! .

2)Will work instead uA meter for discrimination a digital voltmeter? tension dwhat o we have on uA ?""

Regards
Marius

Hi!

RV1, RV2, RV5 trimers no multiturn; RV7, RV8, RV9 trimers multiturn; RV3 potentiometer DELAY; RV12 pot. VOLUME; RV10 pot TUNE; RV11 pot. ZERO;
Digital voltmeter is impractical, difficult to see indication ! G.L!

Coil and coil power source in series with the supply of 555 (audio) of what might be?? What is the max intensity ?

L2 and Lx (power supply), chokes (inductors) 100 ... 300 mkh (100 ... 200 mA)
To limit disruptions in supply !

[цитирам = steaua581; 109497] Здравей Георги ... Имам Vu Metter Fm Fine Tune тип nidle в midle ... ли, че тя може да работи? ... а също и какъв тип "потенциометри" Мога ли да използвам най-добрите? Също така не можах да намеря електрозахранването схеми със схематично публикувано от Гиорги .... е PapaAlex Захранване добре да се използва с Gieorgi схематично?
С уважение
Благодаря

Scheme Papa Alex; THIS IS THE SCHEME OF "PS-G "100% OF G. ZHELEV, drawn from ALEXIS!! See the power of "PS-G "from G. ZHELEV.

Hello Georgi...I have a Vu Metter Fm Fine Tune type nidle in the midle...you think it might work?...and also what type of "potentiometers" can i use best?Also i could not find the Power Supply schematic with the schematic posted by Giorgi....is the PapaAlex Power supply ok to be used with Gieorgi schematic?
Regards
Thank you
Marius

[цитирам = steaua581; 109450] Здравейте приятели,
Имам един въпрос по отношение на VU метър за черни --- цветни indicator.What алтернативи имам вместо това --- О --- мащаб ... Ive Чух, че си вид метра малко трудно да find.Is Има ли алтернатива? ...
С уважение

If you have mikroampermetar simple, do it with zero in the middle, such as the shift pointer mechanically ,opened mka and carefully move the pointer in the middle and you will receive> 0 <mka.

Question

Hello Guys,
I have a question regarding the VU meter for Ferrous---Non Ferrous indicator.What alternatives do i have instead of that ---O--- scale...ive heard that type of meter its a bit hard to find.Is there a alternative?...

GND is negative.

GND negativ!!! There is your problem. Should revise the scheme of the sampler(2х 4538 ), or to change the sheme of positive GND (GND +)
G.L!

[okantex]

GND is negative.

[georgi.g.zhelev]

I tried , but at begining there was positive value.
change was to higher positive numbers. there was no decrease .
thanks

Hi! Your scheme; GND-12v? or GND +12 v?

[okantex]

I tried , but at begining there was positive value.
change was to higher positive numbers. there was no decrease .
thanks

[okantex]

first sample at 100mks
second at 150mks
ok . I will try soon
