My Digital Pulse detector Delta Pulse 3

[Nicolas]

Hi Nicolas
-Remove all the components which depend on the +5v like glcd,pic,4094
Then measure +5v on out of 7805 ,,,In order to determine Is 7805 or not Mistake.
- 2n2097 180-degree wrapped
- bs 250 Keep

Hello Jap thank you for reply. for the +5v I resolved the problem it the connection to GLCD pin 1 is GND not +5v

Yes I have changed also the two transistor 2n2097 because is bad placed- I return 180° yes is correct

Also bs 250 I have return 180° because I have the type of bs 250 the drain is to the right

Now the IRF 740 is not warm

but I have one other problem always sound in my DP when I connect the coil and keep signal. the current in coil is only 0.05A

the two led A and B is always off. I think the problem is the 74 HCC4094BF because I have replaced by 74HCC4094B1.

Hi Jap

I checked all is correct now. The 2n2097 is correct and BS250 following diagram and picture I attached here. the IRF740 not warmed

I changed another PIC 18F452. Now all is correct.

my problem has not solved yet is that the coil does not detect anything.

only detects electric fields!!!

the current in the coil is still 50mA

how to solve this problem?

hello excellent project, build me one and I wish you business is not in my power, could help with the costs of hex arechivo the pic, I'd appreciate it thanks my email is: [email protected] Thanks ....

Hi pigeon

how is your DP3?

it works well because we have problem

bad frequency and the coil no detect objet alywas sound when it is connect

for the BT169D you can replace with Bt170 or connect charger direct in battery and not use the circuit of charger


good luck

hi to all

hey jap
we can"t edit demo hex file with winhex software or hexaditor?

Hi alonejax
-U can"t edit HEX file!!!!!!!!!!!!!!! , forget,,
it was a waste of time.

_U must have c.file to edit & get from it NEW HEX file ,,,, -If you are an experience, make New better work .

thank you jap,maybe any body can write new hex file
any boady don't have full hex file?

hi Jap


is a good coil for dp2? thanks
do you have good coil for dept?if give me i so thank you bro..

Hi alonejax
-try with Coil-Calculator to test .

Hi pigeon
-BT169D=MCR100-6
---For assist Download datasheet of BT169D & MCR100-6 replace it In relation to arrange of pin K,G,A.

I do the DP3 three months.Did not succeed, my WG12864B can not display properly, I suspect that the HEX file can not be applied, I am very disappointed

Hi liudengyuan
-IF U HEX file can not be applied-->U cant ON
-test u connection!
-TEST +5V
-test contrast R37,40,43
