Candle Simulator Kit

This circuit was developed as an offshoot of The Rabbit Hole, our local hackerspace's pumpkin carving night. There was interest in using LED candles to illuminate the pumpkins. And we didn't thi...

I need more

I need about 10 more of these kits, maybe up to 15. Can you get more of these, I purchased what you had!

A fun easy project.

I like the project so well I am buying a second one and modifying it ti better suit my needs. The red LEDs detracted from the effect I wanted and I am going to try amber and white mixed with higher output LEDs. I placed the module in the bottom of a new Kerosene lamp after removing the wick. The LEDs are in the slot where the wick would be. I used tissue paper to diffuse the light. I want to change to 3 AA batteries so they can be charged by a nano-hydro waterwheel (http://tigermountainsprings.net/) on one of our creeks. I may add a light sensor so it is only on at night. I will also add some 1 Watt LEDs separate from the module that will activate on movement. Review Image

Exactly what I was hoping for!

I love the cheap led tea lights you can buy everywhere else, but they're not bright enough to produce the light you'd expect from a candle. This simulator does the trick! Not only was it fun to build, but it worked exactly as shown in the videos with no tweaking. I'm using mine in a scarecrow with a jack-o-lantern head for Halloween, and even though the head is larger than an average pumpkin, it fills the whole thing with fire light! I ground the rounded lens off the LEDs with a dremel so they'd be less focused, and it really helped spread the light around. The only thing I might change is swapping out the red LEDs for a more realistic candle flame color, but I do like the subtle change between the two colors that helps sell the flicker effect. I will be back for more! :)

Looks Great

The LED Candle Simulator was easy to build and solder using the instructions provided on instructables. Worked first time and it looks great. I am new to soldering but was able to put it together without issue. Only question I hand in construction was in regards to R2 but that slot wasn't used.
