A reader reminded me of the LumiGram FibreOptic fabric sample I got a while back. I made quite a simple modification to the sample, adding an auto-changing two-leg Red-Green-Blue LED.

The connector is designed to come apart so you can change colours, or packs in case of damage. The plastic tube pulls back onto the battery-pack leads. A small plastic cage comes away in two pieces. (It's used to hold the LED pointing directly onto the ends of the fibre-optic fibres.)

So I just wrapped the legs of my RGB LED in electrical tape, placed it in the register marks of the cage, and held the whole thing together with more tape. (It's a temporary set-up.) Then held a 3V coin-cell battery between the LED legs, and voila.


A look at the connection mechanism. My LED in cage on left, provided LED and sleeve on right.


The RGB LED is rated for 4.5V, and I think here it really would benefit from the extra power. (Surprisingly it's quite a sunny day here.) Otherwise, yeah, kinda nice. Here, have a video.

You can see the colours being produced by the LED on the left, and on the very right at the end of the fabric see how it gets mixed. With a bit more power it would be prettier.

My sample from LumiGram arrived!

Show&Tell )

This fabric is very very delicate. You can't really cut it into non-geometric shapes, can't fold it or bend it too much across the grain, or do anything to damage the fibre-optic strands. But as the LumiGram website shows, there are still plenty of things you can do with it. I'm going to try incorporating this sample into a piece of clothing. And if it goes well, maybe come up with a bigger project to do with this stuff. But it'll have to be on a body area that doesn't move too much! Still... pretty...
