My Digital Pulse detector Delta Pulse 3

[jap]

Hi All!

I Almost done with the soldering, but I need some informations:

- I bought a LCD, this: http://www.ebay.co.uk/itm/160375870532 , than i would like know which resistors need to? R37, R40
- P1 is 3 pin, than wire go to LEDs?
- D8, Idont found Schottky, which value is it?


Thx

Biogas

Hi Biogas
-For U glcd R37=2.2K,R40=6.8K,R43=47.
-For D IF NOT =SHORT
-P1 is 3 pin?--->PIN2 IN P1 COMMON +12V

Hi Jap!

Thank your help!

Can you share your DP3 photo? (I would like see, what I wrong done... :/)

Hi Jap!

I need a lot of help, what I write whit red bolt italic.

Frequent questions for DP3 ver3 and easy board was divided into parts as schematic:-
1 - part of the coil and power.
2 - part Charger and can not mounted it.
3 - part programmed controller + keyboard + audio{SP} out.
4 - part GLCD and control.
5 - part scope and its components.
6 - part determine the type of metal and match between the signals used by pic.
7 - part of a normal delta pulse .
-----------------------------------------------
I've put all the notes in every part of the answer to all questions.[*]-dEMO HEX =~ver3 used only in ver 3 pcb.
-start test with coil 40cm , 3~4 ohm,400~500uh. How many is the wires diameter and how many turns? For 1x1 m coil, have you information? Wires diameter (CAT5 is ok for it?) and how many turns? (4 m CAT5 wires is enought?) And how can I connect to the 5 pin connector? Or I need just a 2 (or 4) pin connctor? Than conncet 8 wires to 1. (or 1-2.) and the another side the 8 wires to the 2. (3-4.) pin(s)?
-Must use keyboard sw1~5. 1-5 pins are 5 keyboard, what is the 6. pin?
-follow measure at points as schematic & PDF .
-adj TR1 Will help in setting.
-all value of R,C are All worked and change values for improvement.
-All value of R=560 will changed later to improve performance.
-All value of R of U2,D6 Can be modified to obtain the best results.
-Most problems of choose different types of GLCD and followed connection method.
-R43,37,40 Changed for the relation for GLCD[part 4].
-in case not use Charger ,can use sw on/off in P3[part2].
-all C 100n is mk type.
-There are important components in the function, such as Q3,4=2n7000,Q6=BS250,D4=LF357,D6,Q5,Q9,U1.
-Responsible for higher sound both T14,R79.
-Responsible for the delay in the start vd12, C22,C24,C28.
-The difference in results is due to the difference in components and quality of connections of the pcb.

For battery pack is enough 10 (or 12) 1,2V AA 2-3000 mAh battery, or I need another 12V battery whit high capacity (mAh)?
What is it the two leds? (Low battery and battery charging?) First Pin is a LED, third Pin is an another LED, and what is the second pin? (+12v coonnect?)

Thank you!

Hi!
Is Pasha still selling pic? I would be interested to buy pic or kit.

Hello Jap
Please do not go out from Forum
I have some questions

[volcano]

Hi Jap
Thank you very much
You have guided me to change somes resistors in the in my 1st project (PIM-2).
And I have done the same thing with the 2nd project (DP3).
Now I am very interested for DP3.
But I have a problem ( the display run without coil normaly, and it does not run when I connect the coil)
and when it is ON, just I connect the coil, it will be OFF .

THANKS

Hi volcano
-When it switches off when you connect the coil it means it is working short on the battery voltage decreases and thus reduced voltage of +5 volts
-the IRF740 bad
-change VD7,VD8
-Test & change VD12,13,15,C22,C24

Hi Jap

You are right

when I run, the tension decrease to +5V

So I will do all what do you say to me

thanks

[volcano]

Hi Jap
you are really wonderful
thank you very much
I changed IRF740 and and diodes.
Finally, the display is ON with coils.
But it remain a one problem : ( I can not get this bandwidth ).



I want to say that I have the first problem ( the PIC can not detect the coil )

THANKS

Hi,
finally my OSC looks like this:

Hi turboaleks

Congratulations to you

Hi Jap!

Thank you!

If I have time, than I do it onward, because under Family (1 year olds girl), and under Work it is not possible...

[turboaleks]

Thank you Volcano. I hope you will finish your DP3 soon.

[volcano]

Hi Jap
it remain a one problem
the PIC can not detect the coil.
the IRF740 is very hot when I connect the coil.
I can not get this bandwidth.



thanks
