Allright, i know how to do this using relays and steppers and all that stuff, but I figure there's a solid state solution and I'm looking for someone to help me out.

Here's what I need a ciruit to do:

It needs to power three lightbulbs in a fixed sequence. it needs to light one, light the next, light the third and then shut off and repeat itself until power is terminated to it.

visually each X is one light on, O is a light off
1-XOO
2-XXO
3-XXX
4-OOO
5-XOO
6-XXO
7-XXX

And so on and so forth. I would like the flash speed to be adjustable as it needs to match an existing flash pattern.

If anyone could help me out i would really appreciate it!

uh...solid state relays? lol sorry...

I said I can do it in steppers and relays, I'm asking if anyone out there knows how to do it WITHOUT them. Read before responding.

Justin

I can design a printed circuit board and write the code to make a microcontroller do this for you for a fee.

You're talking 120VAC light bulbs right and not just LED's?? I have a bunch of left over optoisolators and triacs that I used one year for a TJ christmas lights competition using a computer to control them, so I have this figured out too.

It's 3 12 volt 1157 bulbs (automotive brake lights). What would you charge for this?

At this point i'm not 100% sure i need it done. Half of the circuit works, but the other half doesn't. If i can get the other half working I won't need this, but I need to keep all of my options open.

Dude, I read your post, relax. Just trying to joke around a little bit.

heads up, no matter how much you don't want it to, sarcasm tends to get lost over the internet. I've also had it up to my nose in people saying 'this or that won't work' even though i know damn well it will.

There are alot of idiots on earth, but people need to stop assuming that anyone that asks for help with something is an idiot.

Justin

Oh, i get it, a tail light sequencer.

I can build two sequencing circuits (one per tail-light) for around $35-40 total. This includes two printed circuit boards, all parts, etc. Speed is adjustable via a dip switch, controlled by a microcontroller and not some crappy 555 or other "analog" solution.

Interested? email me amlmr2@umr.edu

555's aren't crappy, they are just overly simple and don't require the programming that a microcontroller does. Granted it would be "analog," but it would be reliable.

They rely on a rc network most of the time in order to function, therefore in my opinion they are still an analog part and subject to varying operating conditions dependent on the temperature response of the rc combination. Sure, 555's are simple elegant solutions to many problems, but I don't like setting the timing settings of something with resistors and caps anymore.

Then don't be such a jackass about stuff. Many times the people who joke about it know more than anyone else. I found the inherent sarcasm in his statment, maybe you should either be more perceptive or less sensitive.

I think your idea is cool. Old Mercury Capri's had it. Anyways, do you really need it on PCB? It would be much cheaper to solder the circuit onto a project board.

By the way, go FTE. I'm on there too.
