Thanks for the answer Sarge!
First of all, this is not my car or motorcycle's tail/brake light conversion project, I've already done that a year ago to be more bright in the night, and explained how I did it in your "Ok, where are we now in automotive lightning" thread. I had two accidents on a motorcycle(not because of my brake/tail lights), I almost end up dead, so I know what are you talking about. I really do.
By the way, I'm no liar (and not telling you that you called me a liar ) so if it was a car project, there is no shame to tell that. But this is something very close to that when you look at the circuit way.
I do understand why are you thinking like that, and I know it sounds like a auto project, but as I said before, the very first circuits I've tried to accomplish was also tail/brake circuits which I got from this forum. I searched for the keywords of my project and end up finding that circuits.
My personal belief is, if security is involved, I should clearly know what I am doing. Not only for car modifications for every single thing that is dangerous in such a way. It can be a project like, doing your own RS232 contoller and adding it to your PC.
Anyway, my concern about the 9v -12v difference is because of the instant voltage drops here. I may use a UPS but it wont be very healty cause I need an online one of them, and they do cost too much instead of the line-interactive ones.
My basic idea about feeding the system is like,
- regulate the voltage from the dc source to 9Volts.
- use a couple of cap's to make sure leds wont die in long (1sec) power outages.
- regulate the voltage and current so the uC nor the leds will die frequently.
I don't wanna repair a part of the system everyweek, I want to build something reliable, won't die in the middle of the show.
I appreciate your concerns Sarge, and I agree with you. If you were to see how the cars modified in our county you wouldnt believe your eyes. People run on fog lights instead of headlights at the night. You dont notice them well and these things frequently cause accidents in Turkey. They use strobing tail lights, (they strobe all the time) strobing headlights, fake police light inside the radioator panel etc... So you and I have the same anticipation about these non-responsible people.
Anyway, I presumed that we will have 1A for each channel because I still didnt see the table I am going to integrate with leds. There may be more or less I dont know, because of that, I want to take this into count as high as possible so there shouldnt be any problems after completing the circuit and running it for a couple of hours.
I had to be sure that no contestant will catch fire just kidding...
Thats why I want to drive the leds over mosfets. In case of we need higher currents in the circuit, I will just change the mosfets and caps and move on right?
Anyway, If you need any specific elements for your circuits, I can try to find here in Turkey. As I said before, I'm very lucky to have my office very near to the electronics store's street, so I just walk for 5 minutes and find myself in heaven
