Step 10: Attach the Fiber Optics

You can get plastic fiber optic cable bundles online from sources for creating starfield ceilings. The skirt takes around 200 feet of fiber optic strands, which you can obtain in lots of different configurations. However, I highly recommend using a bundle with a high strand count – both because the cost per foot is cheaper that way, and because the protective outer sheathing is much easier to remove from the bigger bundles.

Over-heating the fiber optics can cause them to melt – so if you have some spare heat shrink tubing and LEDs, it can be good to practice the fiber optic attachment technique before trying it on LEDs that are already sewn to the ribbon. Just put together a bundle of short/scrap pieces of optical fiber, and use them to get a feel for how long you can heat the whole assembly before you should move the heat gun away.

Carefully strip the sheathing off of your fiber optic bundle

Use a hot knife or wire cutters to cut a variety of lengths of optical fibers, from about 6″ to about 2′ (or longer, if you like). If you have a hot knife, that’s the preferred method for cutting the fibers – but some light degradation is acceptable, so wire cutters will certainly do the job.

Gather a bundle of cut fibers approximately 5mm across, aligning them so one end is flush

Dispense a small amount of clear silicone adhesive onto the tip of an LED, in the heat shrink tubing – enough to cover the LED with a 1-2 mm thickness of adhesive.

Insert the flush end of the fiber optic bundle into the heat shrink tubing, pushing the ends tight to the LED surface as much as possible.

Use a heat gun to carefully shrink the tubing around the fiber optic bundle. Keep the heat gun moving – focusing the heat in one spot for too long can cause the fiber optics to melt.

<p>you could do this same thing for cosplay costumes that need parts that light up i have seen lots of wings being lit up by led lights but in my opinion there to bulky for some costumes fiberoptics are lightweight &amp; flexable much better in my opion</p>
Nice, I'm to made it as a birthday gift to my daughter. She is five years old and she will be crazy for the bling blings :))) thanks!
<p>Great project I can't wait to get started : ) </p><p>I'm a little confused about what type of fiber optics would be best to use, do you have any suggestions? Do they come in spool or is it best to get it in some type of bundle.</p><p>Any help is greatly appreciated! </p>
I love this skirt and this is wt has gotten me wanting to learn arduino just so I can make this skirt!
found a video: http://www.youtube.com/watch?v=Df4aRbmQfjQ
I'd love to see a video of the design in action!
This seems really pretty!
I love the color-changes! beautiful design &amp; idea!
Thanks for sharing your amazing design! I can't wait to make my own Skirt Full of Stars.... :)
