DaOld Man:

You do know you can wire the coin door lights in parallel with the marquee lights?
It would save you the cost of two more splitters.
Just run a wire to one of the lamps terminal, then to the other lamp's same terminal.
repeat the process with a different wire to connect the other two terminals.
Then connect the two wires to the wires going to the marquee light. Polarity doesn't matter, unless you are using LED's for the coin door lamps.
Like me express again that I do not like using the computers power supply for such things as coin door lamps, but if you really want to do it, it should be ok.
Why do I not like doing this?
(1) The chances of something shorting and messing up your computer's power grow exponentially with each device you add.
(2) You are adding more current demand to a precisely regulated, switching power supply. More current means more heat. If you are using a PC in its case, the heat adds to the PCs heat.
But that's just my opinion. And that will buy you a coke, if you put a dollar with it..
Good luck on your project! :cheers:

Really sorry, but I dont quite follow your instructions - I'm a bit confused!!!

For the marquee light, I am using the Nova Matrix LED based light from GGG. This requires a 12V feed, where as the coin door lights - the Nova Gems again from GGG, require 5V each.

If this can still work, could you please explain again for me!

Thanks, Paul

DaOld Man:

Oh, I am sorry. I thought you had regular coin doors with the incandescent 12 volt lamps.
I am not familiar with the Nova Gems. They look really neat though.
If you go to the GGG website it has instructions for wiring the novagems to the ledwiz.
Here is a snip from the website:

Connection:

The buttons have 2 wires attached to them. One is RED and the other is BLACK. The BLACK lead goes to the LED-Wiz™. The RED wire goes to +5v. Be sure that the power requirements for the device are met properly, otherwise damage may occur to the components the power is being drawn from. GroovyGameGear / IDVT Inc. will assume no responsibility for damages caused by improper use.

If you look at the wiring diagram for the led wiz, I would say the two blacks from the novagems both connect to terminal 16 of the ledwiz.
Both the reds from the novagems connect to the same red wire that feeds the ledwiz.
The novagems require 5 volts, so DO NOT CONNECT THEM TO THE 12 VOLTS YOU ARE FEEDING THE MARQUEE WITH!!!!


If anyone else here can explain this better (Randy?) please do so..



DaOld Man:

I was just reading more on the ledwiz.
If you are already using the terminal 16 for one of your buttons, you may just want to connect the novagems black wires to the black wire feeding the ledwiz.
Or if you want, just buy another splitter and connect both red wires from the novagems to the red wire of the splitter, and both blacks from the novagems to the black of the splitter.
This may be the easiest way for you. But I dont think you will need two splitters.

My apologies for confusing you.
I just got around to checking out your blog.
Very impressive control panel!!

pboreham:

Thanks, that makes sense!

So you can connect the 5V Red from the splitter to BOTH red wires from the LEDs? So its a bit like this...

From LEDs Switch

    RED       BLACK
    |   |         |   |
    |   |         |   |
    |   |         |   |

Thanks for the props for the control panel - very pleased with it!
