This instructable is very EASY! IF you know how to connect a LED to V+ and Gnd. This is for you.

I had some spare 3mm fiber optic cable from my previous project,that need to direct IR light source to a very focus beam to use on the IR camera.

It would be a waste to leave the balance items at one corner, collecting dust and remained wasted.

EL wires are cool, but they are kinda pricey and need a 9v inverter to work with.

Part list.
2x blinking LED 5mm: s$0.5 each

3x 1.5v cell battery. FREE. Pulled out from cheapo laser pointers.

10cm fiber optic cable 3mm diameter:s$1.2 (s$12 per meter from Sim Lim Tower, Singapore, B1 Continental electronics)

11cm 3mm diameter plastic tube. It is those you use in your aquarium to connect to an air stone. FREE.

total cost:s$2.2

Step 1: The Body of the Bling

1. Insert the 3mm diameter fiber optic cable into the 3mm diameter plastic tube.

fiber optic cable is the media for light to be conducted.
the transparent plastic tube provides a housing for the optic cable. We will be using it to hold our LED.

2. If it is difficult to slide in the fiber optic cable into the tube. Apply some mineral oil to lube it. I have used some johnson&johnson baby oil. Can't seem to find my mineral oil from the local supplies.

Step 2: Add the LEDs!

1. Shove in the LEDs at both end of the plastic tube. A pair of sharp nos pliers come real handy.
2. Make sure you do not break the LEDs by using too much force on the pliers.

3 repeat step2 for the other end

Step 3: All Wired UP

I used 4x 1.5v cell battery as the v source. All these badboys are encased in a plastic drinking straw which fits them like a glove. These are my voltage magazines that going to sustain for party whole night. Made a few, they will come in handy.

now, make the +ve to +ve and -ve to -ve connection between the LEDs and the battery.
Use the method of your choice listed below
Solder, pigtail wires, conductive glue etc.

you might want to add a slide switch, just in case you want to turn it off.

Step 4: It Is Party Time!!

Where it on your neck as a deco
as a bangle
decorate your bag, your jacket ala TRON (I am so gonna watch it when it is release in the cinemas at the end of the year) on your shoes.

On a side note,
if you have some SIDEGLOW fiber optic cable come in handy, it might pull off even better.
Alternatively, you could carve the surface area surrounding the perimeter of the fiber optic cable. Too troublesome LAH!
