Delta Pulse

[aft_72005]

Hi all
i can not find the D(BAT46)
i want to change D(BAT 49) .CAN I CHANGE WITH (BAT43 OR BAT42)?
can you help me for this problem?
regards!

Hi 786
If your opinion using this schotky diodes for deltapulse , you can
Use instead of it, 1N4148.
Regards.

i want to use on XR71

Hi
aft_72005
can i use on XR71 TOO?
THANKS A LOT FOR REPLY.

[aft_72005]

Hi 786
1N 4148 is DUS diode or it is popular.
Shotky diode specification and characteristic had many different with 1N4148.
In switching applications we cannot use DUS diode instead of shotky diode.
But if you use IN4148 for timing section at pin 14, 4538 IC in xr-71. yes,
You be able use it.

help for build coil.

Hi all
i live in small city.
i can not find wire 1mm . it is here 0.9mm (AWG 19).
i want to build 1*1m coil and 60*60.
turn 1*1m = ?
turn 60*60=?
and i should use shield or no.
thanks.

anyone know this software please help me

Hi all
i want to ask ,can i use this software ( Virtins Sound Card Instrument Manual ) instead real Oscilloscope?
i think that this software does not work more voltage (Signal with high voltage can easily burn your sound card or even your computer)
is it delta pulse tr0 tr1 ... and pins TLF356 more voltage? if "yes" can i decrease voltage by resistor then measure them?
anyone know the software is useful please tell me.(i have one laptop pc).
Thanks alot for reply.

[HELLO ALL]

help for build coil.

Hi all
can i build the coil 2(30*30) instead 1(60*60)?
what wire... and turn ...?
thanks

help for build coil.

Hi all
is it Inductance Calculator Coil 1.1*1.1 (D=140cm) turn 17,AWG 19( 0.9MM)=770UH?
can i use this coil ?
it is not here article about problems and method repair (like hammerhead.)
all have a nice day.

Hi all
i want to build the coil with wire 0.9mm too because i have very much this wire.
any body know how much turn with AWG 19 (0.9mm)
1*1m = turns = delta pulse one side= ? delta pulse two sode= ?
1m = turns = delta pulse one side= ? delta pulse two sode= ?
75cm = turns = delta pulse one side= ? delta pulse two sode= ?
1*1m = turns = xr71 =?
1m = turns = xr71 =?
75cm = turns = xr71 =?
please tells me.

thank

is this the teach

Hi all
i think shema metal detector without file's protel maybe build that is wrong.because....?
i duilded 3 delta pulse two sides
2 delta pulse one side
1 xr71
but all those does not work very well.
i think that this is article had prejudicial if does not had files (protel 99 or dxp ) because for change any piece should adjure until anybody answer
if this site name is the geoteach then was help without discriminate.
***************
please anybody knows which resistors are for increase(multiplier) frequency ,and wite max increase or decrease resistors.
thank for replay

Hi Hl54
You can see two various drawing Schematic diagram for delta pulse at this thread.
One from micron electronic and another drew by good friend Vladimir in proteus area
These two are ok and without error.
About pcb , I don’t build tow layer but single layer is ok . I change some section of
Singel layer pcb that you saw the version of it in this thread .
And my result with 40 cm diameter coil in air, can be detect soldring grease box with
6.5cm dia between 70-90cm.

[aft_72005]

The network which be able changing transmitter frequency contain R1=680K,
PR1=200K, C1=15NF around 556 ic.

Hi dear aft_72005
thanks for replay.


Hi dear geo
you said :
17 turns with wire 1mm is OK
can i 2*50 cm instead 1*1m? if yes , turns = ? wire = ?
already you said too :
26 turns awg 0.5mm DIM=75 (60*60)
can i 2*38 cm instead 1*75cm? if yes , turns = ? wire = ?
have good day and night.

Hi hl54. Sorry for late reply.
What are you mean 2*50 or 2*38?????
explain me.
You must know that Delta Pulse needs a coil of 1000uH inductance

HI! KT-315

I DECIDED TO BUILT THE DELTA PULSE AND I PREFER YOUR PCB DESIGN. SO THAT I NEED THE PCB WITH COMPONENTS LAYER.
IF YOU HAVE THIS PLEASE ATACH HERE.
