great project.
For the rotating section you could use a rotary feedthrough or multiport swivel. Got to check ebay there should something be available for a few bucks.

Here's an idea:

If you need only + and ground you could use a music jack like this

https://www.ebay.de/itm/3-5mm-Mini-Jack-Socket-to-6-3mm-Jack-Plug-Adapter-GOLD/200306388645?epid=1905297515&hash=item2ea330eea5%3Ag%3AaWsAAOSwNe9aQglg&LH_PrefLoc=2&_sacat=0&_nkw=6%2C3mm+jack&_from=R40&rt=nc

It is rotationally symmetrical, the plug can rotate in the jack, if you use stereo you can feed through 3 cables (e.g. steadylights, flashing lights, gnd) video for 4 cables and it is dirt cheap. Needs to be mounted in the center of rotaion though

Otherwise you can look for Through hole slip ring connector

Will this kit be available for others as well?

Yeah ive been looking at slip rings, and did briefly consider using an audio jack, but they'd have to be around the center of rotation, which means either inside the supporting rod, or would have to cut the supporting rod so the sections can rotate separately.

What i'm thinking, is to basically turn the centre rod into a headphone plug. So drill a small hole for wires to come out, connect them to a couple of rings of adhesive copper tape around the rod. Then 3d print a cover to go over them, with a couple of copper or aluminium sprung contacts (probably salvaged from my parts box), within the cover.

So effectively turn the rod into a headphone plug, with a jack that can rotate around it. Make sense? Might be easier once ive drawn a model of it. Hopefully i can integrate it into the large gear that will attach to the bulkhead, do it all-in-one.

And yes this will be available to others. In fact i'm already printing one for someone.

Decided i should design something to make the rotating hab section, actually rotate!

I'm going to attach a large inverted gear (teeth on the inside, opposite to a normal gear) to the center support bulkhead in the rotating section. Then clamp/screw a small platform to the central aluminium tube that runs down the centre of the ship for support.

On that platform will sit an Arduino Nano, and a servo modified for continuous rotation. I do have a small stepper motor i could use but i dont think it will have the torque to rotate the whole section, which weighs about 1kg. Will have a small pinion gear on the servo, which will in turn drive the big gear on the bulkhead.

By going small pinion to large rotating gear, and by controlling the servo speed i should be able to get a nice slow rotation.

Also by mounting the servo/arduino on the support tube, they wont actually rotate, so they can be powered externally.

Only problem is that this will make it difficult to light the rotating section, as any wiring to it will also need to rotate. If its connected to the same power, the wire will wrap around the tube and seize up. Only 12 LEDs in that section, may just have to throw a 9V battery in.

That is really well done! I love the hangar shield lighting
Who makes this kit? How big is it?

Thanks TK Iain,

The warp core was a fun thing to build. Especially the light core and figuring out what led's gave the best result was a challenge that in the end paid right off.

Hi - seems the build pics have been lost. Any way they can get reloaded? I am really looking for a good spotlight suggestions for my NCC-1701 refit 1/350 build and need some visual examples to help with the text. Thank so much in advance.

Hi there.

I am so sorry to say that when Photobucket collapsed/wanted money I lost all the pics of this build and a few others.

Sorry I can't help with your request.

Thanks. I thought insead to stick the photoetch with ca glue . Follow this with Krisal clear for the windows . Place clearcoat then decal.

Hi - have had the PolarLights 1/350 NCC-1701 Refit sitting under my workbench for years and I'm trying to inspire myself to get 'er done with lights and nice painting. I will probably lean on this forum for tips, tricks, ideas, thoughts so I don't get snagged in "gotchya's!"  Thank you in advance!!!
