Yeah I've seen that wire. I may use it for the next build. I'll connect a common negative so I don't have to feed too many wires down the tube. I may use the Arduino board to run all the lights, got myself a starter kit and i'm just learning about that.
I've updated my blog. Pop over and take a look. Prydien's Blog | USS Voyager Model building
I haven't got too far to go now
I'm going to use 'Micro Krystal Klear' for the windows.
I've got some dental acrylic recommended by Steve Neil (look at his youtube channel >steve neill's garage< he's fantastic, a real inspiration, he works so hard)
But I think dental acrylic is best used before you paint.
What do you guys use for windows?
Thanks for the comments everyone, all input is greatly appreciated.
