Delta Pulse

[kt315]

hi Nicolas, must still say additionally... Deepers 10DD detector has discrimination ability. but it is NOT the discrimination on principle of 'Ferrous-Non-Ferrous'. it is discrimination 'small target - big target', some threshhold that you can control by a pot.

[Nicolas]

Delta Pulse are working with big coil and for big target finding. big target from ferrous and un-ferrous are leading itself alike.
you had misleaded something in your life.
what discriminator is if DP IS NOT FOR DISCRIMINATION BECAUSE THERE IS NOT
DISCRIMINATION IN PRINCIPLE??? even 28 frequiencies Minelab does not able differentiate gold can from ferro can. why you are so naive
why you do not wish to read books, articles, learn what write in metaldetecting forums? why you so believe in sh-t info from bull sh-t guys?

I AGAIN SAY FOR EVERYBODY TO LEAVE OFF THIS THREAD FROM ANY 'VERY NICE DISCRIMINATOR BLOCK FOR DP PROJECT'.

Hi Kt315

You are right

Thanks to clarify the stupid things

Hy! I build a Delta Pulse discriminator and I have a problem: https://www.dropbox.com/s/c8gqen5si944ccb/00006.MTS
What is the Rx resistor? What is the correct value? I soldered a 100ohm resistor.

Hi

Change the Rx by pot for calculate the value

all LCD type has its value

Cordially nicolas

Good evening again in ALL HERE ..

I WANT YOU TO ask about the pulse , The deformation that exists in the pulse T.X at coil UP . looked a bit picture I believe that it should not be so .
from what can to this is happening ..

[g.s]

Good evening ..

Can someone from here Please note the schematic point (sampling integrator) ..
I want to understand this part..

Thanks in advance..

if you take any PI schematic you will see there a reference point on +12V (+BATT). because you must sheild a coil from +12V, if you want to shield. so this bulgarian schematic is not right on reference. you may use then -12V=-BATTERY or what you want.

Hello.
-12v, so -12 to +12 = 12V.
-12 to gnd = 6V

Regards

Thanks for the clarification kt315 and Geo.

Hello to all, can anyone tell me where is the reference point for DC measurements in this scheme?

[Attilawap]

He used a huge coils, but I don't know what the parameters the coil that I send (youtube link). Because I believe this metal detector can sensing a ring size metals.

what size of a coil he uses at backyard IN REALITY?

[Attilawap]

Please watch this video: http://www.youtube.com/watch?v=XNG0rR9DXyM
The Delta Pulse can sensing a coin sized features relative small coils.

[kt315]

delta pulse is NOT for coins' sized features. DP works with HUGE COILS. HUGE!
