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

[georgi.g.zhelev]

PS-G

My schematic is different. I use PIC .
just wanted to use your timinng .
I got samples in 3us .I got first from 100us. and second from 250us.
first is always bigger than second sample.

TEST: DELAY second sampler 150mks around! (not 250mks)
G.L.!

Hi. You make the scheme or use simolator program? On simolator will hardly get a real rezoltati. Make the scheme a PCB, only then you will understand how it works

Komsu Georgi ,


excuse me , but I could not get same results

all results were positive after subtracting second sample.

Hi serban! 5532 (dual ampl.) Is not equivalent na 5534! Use LF357.OP27 (no OP37). Mikkroampermetar be binding, it is basic discrimination. indicator! LED FER. LED NON FERROS and have little sensitivity
Test should be done not in the workshop, only real test of the field (forest), the scheme is very sensitive. Coil 20 centimeters to 30 centimeters!

A test should be done not in an workshop, the real test may be done only at a field and in a forest, the schematic is very sensitive. take the coil from 20 to 30 centimeters of diameter!

SERBAN, please write what the results obtained, the sensitivity of the sound channel (target) and discriminator, what sensitivity are you working (ferros and non ferros).

G.L!

Salut Marius !
Daca nu gasesti ne5534(5532) si vu-metru cu zero pe mijloc nu are sens sa te apuci de constructia ps-g ; eu personal am construit-o cu lf357 , functioneaza dar momentan are performante la detectia in adancime mai slabe ca delta-pulse .

Thanks Georgi for your project !

salut steaua , dali aj pcb kare je bun jou am fakut dila molah pcb ama nusint sigurat ka jeste kum trebuje dar ojavja tu bun pcb sema alu gjorge jeste misapare korektna de puls star g.

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