LED-Wiz and wiring questions
Franco B:
They should be in the region of 30ma.
So 21x30ma = 630ma + 100ma from your trackball kit = 730ma which is way over the USBs 'available' 500ma.
You will need to run a 5v lead from your PC. Its easy to do. Let us know if you need any help

Thanks so much for your response Franco, very helpful!
Ok, so my official game plan is to power about fifteen to twenty 5v or 6v bulbs, and then also the one 5v one for the trackball. Nix the 12v bulbs, I will be replacing those to be consistent.
I do have two more questions. I've attached a picture that I got from another topic and edited it a little bit. On the picture it lists both of my questions..
1. Is it correct that half of the ports are powered by the USB cable going to the pc, and that the other half of the ports are powered via the cable connected to the power supply?
2. And then I am also confused as to where that other wire goes to in that picture.
Help anyone? Thanks!
Franco B:
No problem :)
1. If you connect a separate 5v source the added amperage is available to all of the terminals.
2. Simply connect the wire to the 5v like you have shown on the right hand side. You could just piggy back it off the terminal strip on the right hand side that is connected to the 5v if it is easier. Basically what you are creating is a parallel 5v rail which all of the LEDs anodes (postive legs) are connected too.

I should have guessed that. ;D
The official directions from the Led-Wiz device mention using an "in-line fuse"
Would I need that for my set up? If so, where would that fit into the picture?

Ok, so I am sort of piggy backing onto my own post here. I came up with another question.
I bought some terminal blocks but I am afraid that I'm not sure how exactly they work.
Is the wire on the one side one single wire that's just looped over and over? And then the LED's all wire up to the one side?
I've attached a picture to hopefully explain what I am trying to ask...
So that question in addition to...
