Walkman, Is there a hex file for the PIC processor from the board?

What's the use, it can only be used 300 times, he is just a decoration. Faroukbns, do you have unlimited program files?

Hi
Can any one share the sprint layout file of this discriminator of delta pulse2 please??

Hello, brother
I just thank you for this project which worked perfectly with me (turkish pcb)
for the ICs I used original circuits from texas instrument with a TL081 instead of the lf357
and I set the pulse widths using the attached help
Thank you very much once again my brother

Can I also have a link to download files ?

H, i nearly finished all, i have 2 question:
- the trimmer P.P.S. 100K which value has to been set? If i move the value what does it change?
- tantalum capacitor are on the bottom side right? And i have to see the position in the picture dp__mir_bot31.jpg in the folder "new board"?
Thank you

hi
1/ noticed on the schematic
2/ noticed in BOM file
3/ 100Hz or 120Hz

tantalum just on bottom side. they all are SMD, just SMD type.
polarity is visible by (+) sign in bottom mask layer, try to look by zoom glass.
PLEASE learn the tantalums using GOOGLE search.

pleasure

R23-R24 and R25-R26 again

I confirm that i received yesterday, really good PCB. I ask you one thing: in the DP_BOM file, in the list there are precision resistors R23-R24 and R25-R26 with 4.70Kohm, but on the PCB is written 4.72KOhm. Do you think that is similar and not important if i use one or the other resistor or is better one value? I noticed that they must be tuned in pair.

good. you had got Winter Project.
there was not a note to set precision resistors but my understanding of schematic says me to use them.
so i added this demand.
you need fundamental knowledge... open tables https://riedon.com/blog/e24-e48-e96-...sistor-values/
you can use - 4,6
4.72
4.75
or, take much resistors 20-50pcs, 1% 0.5%, from/off one party and choice the pairs by measuring.
remember, after soldering their values can floated... another way you can measure after the heating.
all the best

Thank you brother, merci infiniment

take turkish layout of our turkish amigo. it is free. now is a time for Winter Project. good time... long long time under a snow...

Thanks a lot br
Can you share gerber files of sniffer please?

[kt315]

sniff is re-tuned on 300PPS, it maybe good if you use good reserve batt, meaning Amper * Hour value of the batt.

An ampere hour or amp hour (symbol: A⋅h or A h; often simplified as Ah) is a unit of electric charge, having dimensions of electric current multiplied by time, equal to the charge transferred by a steady current of one ampere flowing for one hour, or 3,600 coulombs.[1][2]

The commonly seen milliampere hour (symbol: mA⋅h, mA h, simplified as mAh) is one-thousandth of an ampere hour (3.6 coulombs).
