Delta Pulse

[kt315]

I do not see a problem. what you mean? low sens on a coin or what?

[g.s]

dear attilawap We believe that the YOUR delta normally work..
play around a bit after pot width and delay and threshold and you find that normally work...

GOOD LUCK


ΚΤ give me thread I get and I dvd ...........

I think Attilawap is trying to say that his Delta Pulse is only detecting large metal objects, but not small objects like coins.
Also, surely the ticking should increase in frequency when metal approaches the coil, not decrease.

You guess my problem! My Delta Pulse can sensing only bigger metals but not coin sized features. And this is normally that I take a metal away, the ticking sound surrounding a delay?

[kt315]

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

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

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

[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.

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

[kt315]

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

Thanks for the clarification kt315 and Geo.

Good evening ..

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

Thanks in advance..

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 ..
