Pushing forward on the Lighting Controllers
My soldering skills are growing and my knowledge of the DMX lighting protocol is inching forward.
Pictured are the first part of the required components:
Router
CG 1500 Cable Box Enclosure
5V 60Amp Power Supply
SANDevices e682 Controller
WS2811 Pixel Strings (2 are shown connected)
Laptop for configuration and to run Madrix (the lighting software)
My cat, Mithras... who has not been very helpful
There will be 5 of these boxes on the mothership, each one will control 16 strings of pixels.
What I have learned about the controllers and DMX
The pixel strings are 50 pixels each, Each controller can control 6 DMX Universes
We will be using 5 controllers and 80 strings of 50 lights... for a total of 4000 individually addressable pixels.
DMX address assignment for the controller is a 3 step process.
1. Configure Madrix by assigning pixels to specific channels an DMX Universes
2. Assign each socket on the controller (in our case, clusters of 4 strings) to matching DMX Universes in Madrix. (slightly tedious because it's done via command line, but I'm patient)
3. Map the channels within the sockets to the pixel strings.

Bobsicle takes a crash course in RGB pixels
Considering that I knew nothing a month ago, I feel pretty confident that we are on the right track with the lighting.
We will have 3000 individually addressable RGB LED Pixels on the "belly" of The Mothership. We are using 5v WS2811 pixels we got from Ray Wu.
After a lot of research, I've decided to go with 3 San Devices e682 controllers.

We are going this route because we are controlling a lot of pixels and will be running DMX over Ethernet with something called the E1.31 protocol. Many thanks to Jim St. John of SanDevices and the friendly people in the DoItYourselfChristmas forums.
If you are interested at all, I highly recommend the SanDevices primer.
The flow looks like this:
