WarpeD, I do have an idea for internal access. Stand by for more details on that though.
Roger that, Red Leader. Standing by.
Still bouncing around the electronics playground of the mind. Right now the plan is a good bit more pricey, with an Arduino Uno and a Bluetooth shield (add on card). Given the size and complexity of the project, I will want to be able to get at it after the beast is done. From your pix, it looks like the top of the "wedding cake" would be easy to convert to a removable cover with some magnets in the corners. The Nexus 7 remote control idea is gaining momentum, especially given that I've got some programming challenges to add sauce to the goose. The instructional sources I'm finding are very encouraging.
One reason to keep this train of thought going is that micropro's in models are a great way to add flexibility to a lighting installation. Naturally you don't do this sort of thing for every single build, but I can see this as a great solution to lighting an Enterprise kit - anything with a variety of flashy blinky things. Programming something using C, as opposed to using IC controllers, is the way to go. But that's just the computer geek in me - it's but one good solution.
Still, I can see the day in my mind when I'm sitting in my recliner, and as dusk settles over my living room, I pick up the Nexus and start commanding all of my models to turn on...one happy event at a time.
(And if you knew me, the thought of having multiple completed, lit models is truly a delusion of grandeur!)
Thanks for the encouragement on the Revell Snap Destroyer, too, by the way. I'm torn between a semi-serious build up and some very serious and widely varying experimentation. What's that color you used on yours, by the way, Robiwon?
