For some reason, Yenka thinks that the ICs that are blowing up are powered by 5V, which is 9V less than 14V. 5V is probably the default power supply for those ICs. You apparently have to tell Yenka the ICs are using 14V.

 

You already are using CMOS gates. .... the inverter and the and gates.

oh yeh.
but then what does he mean by use "power connector"?
where and why? whats it do?

 

did you unzip the example file that Jony130 so kindly gave you?


On edit:

What project are you working on where you have 260W and 200W 14V lights?

yes i did and that works. BUt i want to try and get my one to work, and his looks very complicated?
Its a project i need to get done.

Jony130, since u seem to use yenka, would you happen to know why my those 3 components in my circuit are blowing up?

 

Jony130 already told you why the components blew up in post #17

If you want supply CMOS gate in yenka you must use power connector from power supplies folder.

 

Jony130 already told you why the components blew up in post #17

yes, but i dont understand what that means? if you haven't read this post from the start i am a "beginner".

What do i do with the "power connector ", and where do i connect it?

Well I was thought about this

Ok i tryed that, not only do the same things blow up, but now the switch blows up. I put it in the same place as the diagram.

If i upload my circuit from yenka, could you or someone who has it, have a fiddle with it and see if they can get it to work?

yep, no-problem

 

yep, no-problem

ok thanks, its attached to this comment.

Also if you do manage to get any success with it, please try and keep it simple and relativley cheap, because i am new to this and dont wanna destroy expensive parts.
But if you can't, do what you can, thanks alot.

 

inverter and 2 AND gates keep blowing up?? why is that??

The Cmos logic ICs will overheat if you do not properly disable the unused ones. Disable them by connecting unused inputs to ground.

do you mean connect the 'S' pin of the flip flop to the negative?
If so, i tried that, and it does nothing. still blows up.

The S and R pins of a CD4013 must be grounded for it to work. All the inputs on the unused flip-flop should be connected to ground or to the positive supply.

Yenka is designed for old fashioned 5V TTL logic ICs that blow up when the supply is as high as 14V. You must use the "power connector" somehow to power the Cmos logic ICs with 14V.

im sorry but i dont understand much of what you said. Why would the 'R' pin be grounded? isnt that where the power is supposed to come from?
And there is no un-used pins, except the 'S'? so i connect that to ground?

Well do you know of a simulator i can use that is for modern IC's? and is free?

 

Sorry. You are using a 74HC74 dual flip-flop which is completely different to a CD4013 dual flip-flop that I thought you had. The 74HC74 has a max allowed supply voltage of only 6V.
Its unused half must be properly disabled and its unused pins must connect properly to ground or to the supply voltage so that it performs the functions you want.

No, i am using the CD4013, if you check my more recent circuit post you'll see i changed it. But still, it's design is exactly the same. And like i said, isn't R pin the input power and then S pin for negative? because both Q's are output and are for the lights, and the clock is connected to negative with a positive push switch to swap from high to low.

I need someone to figure out why the inverter and AND gates are blowing up, because i have no idea, and unless i figure it out i cant test my circuit because they are holding me back at the moment.

If anyone has yenka, i have uploaded my circuit in a yenka format a few posts back, please take a look and see if you know whats wrong thanks.

 

Here is the simplest version that I can make:



If you have some problem with contact bouncing then you can use as a debouncing device not use D flip-flop in the IC.




PS. C3 and R4 determine the shut-down time.

 

Jony,

the thumbnails are difficult, at best to read. why not just upload the original graphic to the forum?

After adding the pullup resistor on the CD4013 and a pullup on the 555 trig, the circuit works somewhat normally. However, you have not expressed what the desired outcome should be. I know what it is, but what is unknown is your specifications. You have been secretative about those specifications.

 

Jony,

Why do you say that?
The schematics were uploaded to this forum and appear as a thumbnail until you double-click on one then it becomes normal big size.
