im currently building my Millenium Falcon cockpit. I'm adding an LED driven fibre optic lighting system to it.

The top photo shows the LED circuit with a 9V battery attachment, and the bottom is a 4XAA power pack. What connection do I need to integrate the two so the LED's run off the power pack?

Deffo LED's and they do work. Already tried them with a 9V battery.

Can you buy a power pack like that one but one that takes a more powerful battery.

Yes of course. You can also grab the same kind of pack but for 6x AA in series, same effect.

I didn't explain myself properly. I also need to run this 6 LED panel off the same power supply.

I am also planning on lighting the main hold, corridors, computer, dejarik table and the rear lights and ramp. Could end up needing to power around 20 3mm LED's. Gonna have to think a bit more about this one. It's probably going to end up as a mains PSU for that lot.

Cheers, I'll do that. But I still need to know what connector I need to split it so that it can power more than one unit.

I have done a bit of soldering before, so I could give it a go. I'll wait until I have a more powerful batty pack though. maplins sell a 10AA one for 2 quid.

How do you know what voltage an LED needs?

How's the build going - I haven't started putting mine together yet.

Only just started myself.

I like waiting for at least 20 issues before starting. Gives me time to see what others are doing and any problems they have found and how to overcome them. For example, the gun turret is positioned wrong.
