Ah, the alluring glow of the LED light. Whether you're looking to create a bit of romantic (albeit extremely geeky) ambiance, or you just want to have some extra emergency lighting around the house, a set of mini LED candles is a great thing to have. They also happen to be quick, easy, and cheap to make yourself. In this video, executive editor Mike Haney demonstrates how to do it.

Lookin good Mike. For more 5-minute videos keep an eye on DIY channel.

Wouldn't the resistor also reduce the life of the battery; creating resistance(small short/heat), it be better to use a series of leds that wouldn't require a resistor that way all the energy would go into making light from the leds instead of spending some energy in the resistor?

I remember seeing the article by Wallich in the Aug '06 PopSci. I never did the project, but now I am tempted. You should have added the Web site where all of the parts can be found. Three things that would really make this project killer:
- adding a part (photoresistor?) to make the candles turn off in light
- adding a part to make the lights flicker
- adding a photocell to recharge the battery during the day
Keep up the great projects!
