How would I go about getting a candle light effect using a 12 LED ring from Adafruit? I tried Fire2012 from @Mark_Kriegsman , but that doesn’t look right. I want it to just be sort of a bright candle effect, limited color range, and using a palette so I can modify it to be and ice candle for cool nights.

I’ve got a tiki torch using a ball mason jar and a photon to drive the lights. I frosted the glass, and am putting it on top of the tiki torch base you can buy from Home Depot or Lowes. So far, so good. But now I gotta get the right effect. I am just striking out. Good coder, just not artistically creative, so I am not getting something that might look like the flame from a tiki torch.

I might also make it use the Adafruit Jewel which would move the lights farther from the glass. Just a thought.

Anyone creative with this? I’m drawing a blank. I will share my Eagle board via github which fits nicely into the 3" mason jar opening leaving the electronics sealed for the most part.

Have you tried modifying the palette or changing some of the variables around?

I saved these two links a while back. I have not tried either of them but maybe it can give some ideas to work with.

You might also try adding an internal diffusion right over the pixel ring. Maybe half a ping pong ball over the pixel ring or a 1/4 sheet of paper crumpled/formed into an upside down cup shape.

I read this article a little while back and it was super interesting: https://cpldcpu.wordpress.com/2016/01/05/reverse-engineering-a-real-candle/
Use an arduino to log data from an actual candle and then use that data to power an LED.

Thanks guys. Marks code does something fundamentally different though, and even tailoring it, I don’t get something I like. It’s excellent for another project I have in mind though to go with these lights though.

And diffusion isn’t a problem really, the ring sits low so most the LEDs are hidden anyway. The problem I have is that the animations are clunky or tend not to look like a lantern/candle at all. I got something close using heatcolors() but I can’t change the palette, so no ice lantern.

I’ll take a look at the links. Hoping to get this done soon so I get them installed. It’s finally nice enough to sit outside.

@Peter_Buelow - check out the post by @Christopher_Smolinsk and his digital fireplace (put the word “fireplace” in the FastLED community search box and scroll to the bottom). He uses @Mark_Kriegsman ’s “holiday twinkle” code with a palette of red, orange, and yellow. I tried this with a 24 NeoPixel ring using an Arduino Uno and a glass with tissue paper in the glass covering the ring. It looks nice. I am sure you can adjust the palettes and other variables to get the effect you want.
