Re: ?????????IS THIS POSSIBLE???????? (crj_lll)
I'm still trying to figure out what this thing does, you want a 12VAC signal to be sent out when you turn on the power to your car? I'm not sure what you mean by alternating power source and 12V pulse? Why would you want this relay anyway?

A standard relay will not deliver a "pulse". It's either off or on.
Look into a pulse-timer relay. It might do what you're looking for it to do...

Can a pulse timer relay be set to activate by a change in state? This way it would activate when the car is turn on and when the car is turn off.

Re: ?????????IS THIS POSSIBLE???????? (B18C_EJ8)
Im not sure if there is just a relay out there, but im sure you could design a solid state circuit to do the job. You could get everything you needed at radio shack for not too much..But you have to know how to design a circuit. we did something like this in high schoool comp sci class, but i cant remember exactly how

Re: ?????????IS THIS POSSIBLE???????? (crj_lll)
okay it looks like a nand gate controlling a spdt relay..
the nand gate is controlled by the ignition and a cap/resistor setup which would send another 1 to the nand gate...at a rate that is controlled by how big the cap is...
which intern's cuts makes the nand gate return a 0
this controls a MOSFET ... which is used to power and ground the SPDT relay...
thus creating a on pulse to the SPDT relay.
when the nand gate returns a 0 the mosfet has no power, and kills the relay - returning the relay to its normal state...
allowing the relay to switch on then off.. with a DELAY controlled by the cap...

looks like you are trying to turn something on.. right before u start and after u turn off the car. but only for a brief moment. - at least based on the diagram from the12volt..
the only thing that comes to my mind... that could even be sorta useful, is for the circuit to control the interior dome/map lights.
when you start the car the lights will stay on for x seconds and then when u turn off the car the lights will stay on for x seconds... but this is way to complex to accomplish such a task...
seriously, what are you trying to accomplish with this circuit? if you say what you are trying to control, we might be able to tell you an easier way to do it - other than just give u a diagram to follow with a brief explanation.
--------------------
but with your first post.. sounds like u just want a brief pulse when u turn on and shut off the car... like an auto lock/unlock door thing...
they have diagrams on how to do that at the12volt - with simple relays instead of using ICs...
you could just wire in an alarm system that adds these features to your car if your car doesn't do it already...

There is no reason to yell.
If you would read the previous entry, you would see I am trying to produce and automatic 12 volt pulse control by the toggling of the ignition.
I said that earlier and it is said on the diagram I posted. If that is not a good enough description for you, I do not know how to help you then.

other than that? what are u trying to control in your car...
doors? lights? audio??
why are u making this circuit?

This is not a mirror issue. You wish to flame, and that is you right. But the problem is not solved so this thread should not be closed. If you knew what I was doing you did not need to waste everyone's time. I am asking about this circuit. What I do with it is not the issue. IF you cannot positivly contribute then do not waste your time flaming someone.

Re: ?????????IS THIS POSSIBLE???????? (crj_lll)
don't complain about getting flamed...you asked a question...in turn, you were asked a question to help find an answer to yours. why are you hiding what you are doing with this. this question was asked of you 6 times so far<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by bpr0422 »</TD></TR><TR><TD CLASS="quote">what are u trying to control in your car...</TD></TR></TABLE>
...and yet, you still have failed to answer six times...
in order to answer a question...you need to give as much info as possible right off the bat in your very first post of the thread. you've been a member since 2003... start acting like it! you should know by now how things work around here. you're percentage isn't exactly spotless either...i wonder why??? it's no wonder you got flamed.

okay... so your are going to make an overly complex way of doing something... just because some "guru" made a diagram that you CAN'T read.
that sounds like a great idea..
btw if you read my other post.. i describe what each symbol is.
-okay i've recently edited it to include your diagram...that diagram is one way to do it, but its too complicated imo... and harder to replace stuff that can fail...
if a relay fails, just get another one at ANY auto store, radioshack, or walmart
don't just believe that that fancy diagram is the only way to do it.
keep things simple -> https://honda-tech.com/zerothre...95194

Re: ?????????IS THIS POSSIBLE???????? (bpr0422)
I have already read you solution and I have chosen not to go with it. You have come at me with an aggressive tone and I would not trust your advice. Free advice is only as good as the source and since I do not know you I can only judge you from your interaction on here. The first thing you said to me on here was rude and uncalled for, so I will pass.
As for the diagram, I have already gotten all the explanations I need. I am now working on another small problem before I install the circuit.
As I said before, thank you for you responses, but I will pass.
This will be my last response to you on any thread.
Have a nice life.

I didn't know XOR gates where now called nand gates.
An Xor gate works this way
1 2 3
0 0 0
0 1 1
1 0 1
1 1 0
You see that the only time the output is a one is when you have an opposite charge on each terminal.
Now you see that terminal 1 is always tied to a 1 so now we have a time delay on terminal 2. When terminal 1 is a high terminal 2 will be charging by the rc time delay. Once terminal 2 is fully charged the output will shut off.
When the ignition is shut of the opposite will occur. The only modification i might add is to put a 1 meg resistor from terminal 1 to ground. That way this terminal is not floating which is a no-no with digital logic.

Wow. What a douche.
All you needed to do was explain what you're using this thing for and I bet people would have had a better understanding and given you the concise answer you were looking for.

I don't see what the big deal is here. Is what he is trying to do any of our business? No not really, sure it might be interesting to know but not really needed to anwser the question at hand. He asked a simple question lets just try to keep it on topic.

Re: (nsxxtreme)
okay.. i made a mistake.. switched the symbols in my head nand/xor - haven't touched that stuff for 2 years - but really.. why use such a complicated diagram.. when u can just use 2 relays, 2 1k uf caps, and 2 10k ohm resistors?
the circuit using the the IC xor gate, isn't as easy to make, since he will have to use a breadboard, and a project box to house the circuit, then stash that somewhere...
if you use the relays, caps and resistors, all the tiny stuff (Caps/resistor) is covered in heat shrink to protect it... there isn't the question of a small project box to stash.... since the caps and resistors are wired inline to the wires that go straight to the relay.
not only that, but can an ic take 11-14vdc??? i remember in my intro to circuit design class, that most of the ics we used were 5vdc... if he only wanted help on the circuit, he should've just ask the guy who drew it, instead of coming here to h-t asking us. If you ask here, I assume that it is car related, and he wants it to control something in his car, so what is he controlling??? i have no idea......so how can i help?
not taking my advice cause he feels like i flamed him, when really i just asked him the question he didn't answer 6 times, is a bad reason.... ic, unless designed for automotive use, might not withstand the vibrations, and temperatures that a car is subjected to...
