[AVR-Chat] Help with circuit

2012-05-17 by Kenny M.

Hey there :)   My whole AVR project got pushed asside due to a lack of funds so I haven't been on here in a long time.
 
I hope I don't PO anyone but I'm trying to get some help with another circuit  I'm designing (see imageshack link below).
I've tried some other forums but I don't think anyone wants to deal with it lol
 
http://img641.imageshack.us/img641/9539/allcircuits.png
 
Essentially I'm trying to get two circuits to control one set of lights.
The signal works alone, the marker works alone.
But when all three are connected power from the marker circuit no longer makes it to the bulbs. The signal circuit continues to work normally though. I don't get it...
 
I'd appreciate any assistance.
 
Thanks,
 
Kenny

Two LEDs, fed by two resistors tied to a common point. Then that common point fed by two diodes, one from Circuit A and one from Circuit B.

Hey Jim thanks for the reply.
How does this look? http://img233.imageshack.us/img233/9564/allcircuitscopy.png
I added one diod feeding the resistors without it either signals would feed all the other bulbs on the common circuit I would think.

Hmmm -

Not quite.

Get rid of the two diodes next to the 470 ohm resistors.

Add one more diode to the resistor common point

Get rid of the red hexagon

One diode to yellow arrow
Other diode to other yellow arrow.

Sorry :(     http://img214.imageshack.us/img214/2977/allcircuitscopycopy.png
 
 
a) The hexagon simply represents the third power source which when on will turn both led's on at half brightness.
 
b) The arrows represent the power source to flash the appropriate led on full and off
 
c) When power is applied to the "hexagon" AND to one of the arrows that led will alternate between full brightnes and half brightness, while the other led will stay on at half brightness.
 
 
Maybe this would be easier with 2-12V relays, if I can find a place to stick them.

I get a domain unregistered and blocked message on these links.

 

Anyone know how to get around that?

 

Cheers.

Dave.

[AVR-Chat] Circuit 2.0

2012-05-18 by Kenny M.

Hey guys me again :)  I gave up on that other circuit and just put in 2 relays. I have everything working 95%.
 
http://img846.imageshack.us/img846/5051/relaymirrorcircuit.png
 
Now for my one small problem...
 
Lets say I apply a steady 12V+ to the center circuit, now I activate my left signal pulsing 12V+ on and off.
You'll see my right LED flash slightly, then flash brighter until it's flashing the same as my left signal.
 
When the center circuit is dead both the left and right signals work independently without issue.
 
I THINK I just need to throw a diode on 87a on both relays right?

Previously the circuit was to have half brightness with running lamps. 
To do that you should have 2 separate current resistors, one for each 
LED into 87a contact. What I see happening is the current to the right 
side is spiking up when the left side circuit breaks. The resistor 
delivers the same amount of current but now it goes to just one side, 
and it gets brighter.

Okay I'll swap those out tomorrow.
I had that part of the circuit already soldered and heatshrinked so I was hoping it would work fine.
Thanks :)

Thank you very much to all of you, it's finally working.
I took your suggestion and I removed the diode/resistator I had and instead put one of each on 87a of both mirrors.
