Delta Pulse

[salim]

sorry kt315 i maked simple side pcb succefuly but double side make me creasy i will check all track again plz delate FANTASY post thanks br!

[kt315]

salim, the Ground/Zero of the schematic is output of D6A. it is kinda a power supply voltage splitter. you are misleading. DO WHAT YOU SEE AT SCHEMATIC AND DO NOT TURN UP YOUR FANTASY HERE

[salim]

hi i maked double side bord by triti without battry checker but delta pulse note workng at all after making test i found that the ground isnt connected to negative of battery are this normal br!

[kt315]

folks,

you ask me about to sell you the PCB in PM... I did not order PCBs but I have a contact with someone who has them now for release. so please you can request PCB via address [email protected], his name is Sergej. here I attach his PCB. it is new traced one by him, not classic I used of.

trully

Dear Geo and KT315
I finished single side DP.but when i run it after few second NE556 is
very very hot and if dp is not Off NE556 will be burn!
what is problem?i checked direction of diode ,Tr,Ic,electrolit capacitor all of
them are correct i confuse.pls guide me
goodluck

do preliminary/first power-on WITHOUT T1 IRF740! desolder T1 now off! you must get Tr2 and Tr3 signals VERY CLEAR via o-scope AT FIRST - look the diagram! you will get a very great hot problem if Tr3 signal instead the impulse will be some 'opened'/positive DC voltage!

For KT315
Help me pls

Who can measure pulse widths on 556 ? T2 and T3. I thing that latest scope diagram is wrong

yes, 'my' diagram is another than 'original' because I rendered it to what I am really seeing on my o-scope screen and did wish to get. if it is wrong... you can change RC values and get what you would be get.

trully

I failed to translate the most important text in the above poster, posted by KT315 in posting #1040:
"С 23-м ФЕВРАЛЯ!!!"
This means: "Greetings in the event 23 February".
23th Feb is "Red Army Day" or "Day of Soviet Army and Navy" in the former Soviet Union, also held in various former Soviet republics.
23 Feb 1918 – First victory of Red Army over the Kaiser's German troops near Narva and Pskov. In honor of this victory, the date is celebrated from 1923 onward as "Red Army Day"; it is renamed Defender of the Fatherland Day after the fall of the Soviet Union in 1991.
Officially, as the name suggests, the holiday celebrates people who are serving or were serving the Russian Armed Forces (both men and women), but unofficially, nationally it has also more recently come to include the celebration of men as a whole, and to act as a counterpart of International Women's Day on March 8.
The holiday is celebrated with parades and processions in honor of veterans, and women also give small gifts to the Russian men in their lives, especially husbands (or boyfriends), fathers and sons. As a part of the workplace culture, women often give gifts to their male co-workers. Consequently, in colloquial usage, the holiday is often referred to as "Men's Day" .
An anecdote from Russia: Putin decided to appoint the 23rd day of February of global warming, because this should celebrate all the men in Russia. It was this winter, we realized that only through this warming of our women now wear less clothes, and soon they do not need to be coats and sheepskin coats .

But what means "KT315"?
Let he explain this.

I don't know why this question is in the DeltaPulse thread but I'll answer anyway.
Sometimes, when somebody specifies a "4066" they assume that the CD4066 is understood.

Don't you have about 20V on the Goldpic-3 IC4-14?
Observe the "Absolute Maximum Ratings" on the datasheet for whatever part you have. (74HCT4066?) If it's less than the pin-14 voltage, there is your problem.

When these devices overstress there is always the possibility that whatever they are connected to will also take a hit.

Yes thats correct porkluvr..all mine detectors works perfect

start making dualside delta pulse now

I need to know board outer size on this
Do you have size for deltapulse dualside pcb?

I need to know size ...Can anyone PLEASE mesure a dualside pcb for deltapulse

,,so might thats why irf740 and diode get warm ??
