Once you have everything laid out on your desk here it what it will look like. The package includes: The CCFL, Inverter box, Slot cover, mounting screws, and a second box which connects to the mic, the potentiometer, and the DPDT (double pull, double throw) switch.

The second box is the same size and shape as the inverter box. It is a very unusual size being approximately 2"x1"x1" whereas a typical inverter box is 3.25"x1"x1", and having 2 boxes this size does take up a lot of space.


The 2 blue boxes are joined with a 2" wire, which I assume is for the CCFL power. In order to show you all of the components, I am going to use 2 pages. On this page, we are going to look at the non-inverter box and the components that attach to it. This first box (in order from the power supply) has the Molex y-splitter, the potentiometer and the DPDT to select CCFL modes (see below). The wires from the first box to the Pot., the DPDT, and the power y-splitter are each 18 inches long, as is the mic cable.


Here is a close-up of the DPDT switch. ICEe Computers only uses one side of the DPDT, which effectively makes it a SPDT (single pull, double throw) switch and allows you to use the other side of the switch to simultaneously control another device. Below is a quick drawing to help demonstrate what the switch is.




If you look at that picture, the colors of the bars above are the colors of the wires that are attached to the tab. In this case the black wire is ground. When the switch is in the red+black position, the CCFL will respond to sound. In the yellow+black position the CCFL will stay on constantly. Again, if you look at the drawing you will see 3 tabs (the white bars) that aren't used. If you had another CCFL or other device you could attach to these tabs and have a SPDT switch that would work with the CCFL control.

Now let's take a look at the potentiometer. A pot as it is commonly referred to, is a variable resistor which limits current (Amperage). As far as I can tell, the pot is included in the kit as a way to "tune" the sound reaction. The CCFL is more reactive all the way to the right and less reactive when the pot is turned to the left.
