Delta Pulse

[1843]

My coil is 4" (35 Turns) and the test got done indoor since it is free from most indoor noise. (bbsailor suggested to me)
I tested different coils (350uH,750uH,1mH... also with resistor in series them) and I found that instability doesn't depend on the coil.
I think that problem is around D4, but I want to know your opinion...
I also tried with different frequencies. (100Hz,450Hz...)
Thanks for reply Geo

I don't know why it has a such waveform:

[Geo]

Hi 1843.
I opened my DP and i took 3 photos that i attach here. The first is with the power at midle, the second with power at max and the other with power at min. The photow are with a 955 mH coil connected to the detector. It is absolute stable .
Sorry for the bad quality of photos but they are with mobile phone

[Geo]

I forgot something

Ohh i forgot...... My DP works at 350Hz and the coil (10 in) has 8.5 ohm resistor (without resistor in series), i don't remember about turns and wire diameter.

[Geo]

Big mistake

Hi 1843. It was a bag with foil near the coil so the waveforms are not ok. I attach you 4 photos. The first 2 are with power at min and max. The other 2 are with gain at max and min (there is a change at the down place of waveform.

Your waveforms look OK...
I will try to finding the problem...
Many thanks dear Geo,
All the best.

DYNAMIC DATA ON DELTA PULSE

Hi Geo. My name is Paulo from Brazil, this is my first post on this forum.

I´m working on my 3rd detector right now. I have successfully built the Stuart´s PIC PI project and the Clark´s IB project.

Now I´m starting to work on Delta Pulse and I would appreciate some dynamic data such as:
test points tr0 until tr9 figures like range of
pulse width, frequency, dc values, relationship
between them and so on, for debug purposes only.

thanks in advance

Paulo,

Go and wash your a-n-u-s, then come and ask about Delta...

Hi paulo. Sorry but i have closed the box of DP. When i will find time i will open it and i"ll send you the photos of test points.
Btw The previous photos that i sent to 1843 are from TR1

....


These days interest grows on Delta Pulse.....!?
So i made two more.....
It showed as best compromise between costs and performances...
I deeply advice everybody to make one....
Regards!

Hi paulo. I attach you a file that i found today in my hard disk and it has waveforms from Delta Pulse (i don't remember where i found the file, but is very useful ).

para Paulo pci Delta pulse

Sorry! I don't speak english very well. I am from brazil too, I need a circuit printed board for Delta Pulse. I don't obtain to manufacture it and its price is expensive.
