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.
