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

[okantex]

Thanks your method is similar to bugwhisker's QED.
he is making the same at first 10us , you are doing same at 300us.

there is one problem at my side.
I do not have chance to increase signal like you did by TL62 s .your signal is analog ,and you do not lose anything.
but if I get samples from same places , I am losing sensitivity.

thanks

Hello wm6 and forum
This is my final schematic wm6 corriged and working, it is the same that Georgi , just a small adjust in the power supply for the 5534 (47R)..
Also remember my schematic you must paste one and one..etc... to assembling the all.
Thanl you again Georgi,
Alexis.

Also i have put more 2 half amp 062 for experimenting some filter in my board,ok...the numbers for input and output of the op's is in "my own numbers for my circuit boards" everybody can put is own ..every human mind are diferent in the concept of schematic !!! but for final result it work well.

Hi, okantex. I do not understand what it is: Thanks your method is similar to bugwhisker's QED. Please explain better.

Dear Georgi ,
http://www.geotech1.com/forums/forumdisplay.php?f=38

at this link there is project. in this project , discrimination is done by samples which are taken from first 10mks.(us ) .
inspects the change of ( sample1 - sample2 ).

in your method
let say first sample ( ferrous ) is taken from 150mks-200mks A1
your non ferrous sample , 250mks-300mks A2

you are subtract A1 -A2 = difference
than multiply the DIFFERENCE by opamps.

think ...........if there is no metal close to coil , there wont be output.
if there is nonferrous metal , difference will be POSITIVE
if there is ferrous metal , difference will be NEGATIVE

is above correct. ?? I am not sure about it. to my opinion difference always will be POSITIVE ,but in nonferrous metals will be big.in ferrous will be small. but always positive.

please correct me

sincerely

Hi Georgi,

here started bugwhiskers very promising his project named "QED":

http://www.geotech1.com/forums/showp...52&postcount=1

Unfortunately, to date, we have not seen his working detector, except many claims and debate fightings that it is working and even better than newest Minelab. After 4 years of "linguistical development", "QED" is still on promising base: maybe in June (not known which year).

Thing was commercialized even before its launch (price of "QED" kit have to be about 1000 AU$), so no complete public plans, schematic and code, only kit version to buy.

On the other site, your project is here, is public, repeatable and free, and, as we can read - most important, it is working !!!.

Thank you Georgi. You are our hero!

Hi, WM6! Thank you for good evaluation of my work !! G.L.!

Bulgarian Pulse Star

I have a question as i am planing to build also this unit Pulse Star G...how is the discrimination,depht and petformance of the unit.Can someone give me a schematic with the right values i should have w/osciloscope...complete parts list and or PCB if possible...
Can you also point some good project wich might have good discrimination,id target,lcd and so on and if its been build with success.

Hi steaua,

after first post here you ca use Search function of this forum. I hope you use it succesfully.

Bulgarian Pulse Star G

Hello,Yes but i was refering to if therre is the complete project pack with all the files....i know if i will search the forum i might put some info toghether in about a week of reading and trying to distinguish between good replyes bad schematics and so on...It will be verry helpfull to have some test results with this unit and also if the Ferrous Non ferrous option works and discriminates well....Is your finished project Pulse Star G working?
What is the curent progress on this Pulse Star G project?...
So if anyone has the good schematic,right osciloscope values,parts list,pcb.
Or at least will love to have a link...thanx
Regards

You wish someone to search, read, select schematics, make and test instead of you?

Maybe you wish someone to wash your car instead of you too?

PULS STAR-G

Hi everyone! Hi okantex! You do not believe that the discriminator
does it work? I made 2 pieces PULS STAR-G, THEY WORK CORRECTLY! Discriminator WORKS! "FERROS" and NONS FERROS. I will not enter into teoriatichen dispute with you, I'm practicing. He believes that the work will make PS-G, who does not believe it does not.

Dear Georgi ,
I did not say I do not believe it.
Everything is possible,
what is your coils inductance uH value?
according to uH value tile of signal swings, maybe this could give ferrous and nonferrous results.
If will say may last word after trying your way of discrimination at my project.
kind regards

Hi, KOMSHO!
I use coils : 300 .... 500mkH, discriminator works without a problem, nothing inconsistent. tuning to coil is not necessary !
quickly looked to link that gave me interesting proekt.Mikrokontroler and that makes it unique, I prefer the analog technique, because it can be repeated and there is scope for creativity.

Hi, steaua! You are a young person, read everything I wrote here, the scheme is 100% correct and workable. good luck!
