Re: 1:1 Millennium Falcon Console Replica
Looking great! I preferred the all-white accent lights (the colored ones look too Christmasy to me), but you must do what you feel is right, of course.
As far as power goes, each set of lights uses four AA batteries at ~1.5V each, for 6V total. You could probably use a power adapter that puts out 6V DC, or use a 6V battery if you don't want to have to plug something in. (Experts, please correct me if I'm wrong.) I stuck LED strips on my wasteland motorcycle and used a bunch of button cell batteries (12V total) to power them.
You'll need a power supply, often called a wall wart, the kind of thing that adapts your wall plug to a skinny wire to run a low voltage device, like a small radio or many computer accessories, like a router or switch. Around here I have a box of old ones I kept when I tossed the device, but you can buy them at radio shack, generally with variable output settings for different voltages and levels of power. You'll be connecting the + and - leads from the supply to your lights.
The one in the photo below is an old Logitech wireless mouse power supply, that just happened to be the right voltage and 1 amp in power, which should be plenty because these types of LED lights don't require much power to run.
I also happened to have several packages of LED xmas lights and they all use 4 AA batteries, so that's 1.5 x 4 = 6 volts. That's the setting you'll need on the variable power supply or on a power supply you find.
To get to the wires in the battery pack, I had to remove some hot glue, then it was clear which wire was +, which you need to know. I marked it by putting a knot in it.
You'll also need to know which of the wires from the power supply are +. This can be more difficult to discover without a meter, so I just tested mine by purposefully hooking them up backwards. No light then correctly connected them and the lights work fine. So at least in my case there was no harm connecting them backwards.
Once you've sorted out the connections, you'll want to solder and heat shrink the connections.
Plug that power supply into a strip and it will come on whenever you switch that on.
