The next step in this process was to redo the four barrel defense gun on the lower right.
The outer form of the build was not changed. It is four Bar 1 x 8 with Brick 1 x 2 Curved Top End (p/n 30359). Two are trans clear and two are trans neon orange.
To do the wiring on one pair I used this setup. A large plate for stability. Two 2 x 2 plates to hold the two 1 x 8 Bars together.
In the previous build, the controller LED channels were capable of greater than 250mA. The new controller has a 25mA limit. The previous build was set to 20mA per LED. Even though I have 10 LED channels in the new controller (vs four for the original controller), with a plan for 12 barrels in the overall build, something has to change. Looking carefully at the setup in the picture, you can see four limiting resistors, one for each LED, and three wires connecting the LEDs. The two trans clear 1 x 8 Bars will be on one LED channel and the two trans neon orange 1 x 8 Bars will be on another LED channel. Having the bottom and top on slightly offset patterns, might produce an interesting effect.
The wires go down though the plate (unfortunately I had to drill a hole here), through the turntable and out through a 1 x 2 Technic brick. Then I use two Slope, Curved 4 x 1 x 2/3 Double (p/n 93273) parts to cover the wire before it goes down underneath.
This picture shows the wire going down by the gear. I will need to pull the wire back and secure it so that it does not get caught up in the gear. Because the wire descends through the center of the turntable, there does not need to be any service loop for the wire. As the gun carriage turns the wire does not follow.
The final covering. As the build is finished, the color choices may change a little as I try to balance out where the tiles are Sand Green or Tan.
