LED Flicker circuit |
|
|
Hello!
I'm working on an art project that I wish to illuminate with 26 white
LED's and have a simulated flickering candle. I found Bob Bowden's web
page of Hobby circuits and the diagram/description of the "line powered
white LED's" with how to use 25 LED's and how to add more or
less...seems pretty straight forward. But as I'm not a circuit
designer, I'd like to ask for some help with the candle flame flicker
circuit.
My project is a 26 point star that I want to be illuminated by the
white LED's from the points toward the center, at the center will be a
candle with the simulated flame. I like the idea of the line powered
LED's...don't have to mess with a heavy transformer and the wires
should be pretty easy to hide along the frame of the star.
I have been kicking this project around in my head for a while and have
decided that it time to complete it. Any help/suggestions are greatly
appreciated.
Greg

OOPS! It should be BILL Bowden's web page! Please accept my
apologies!

The Oct '05 issue of Nuts & Volts had a short article on using LEDs to
simulate flickering candle flames. Check their website for some info,
although they don't have the text of back issues on-line. Maybe your
local library? The project described in the column isn't line powered
but you might be able to adapt some of the ideas.

Hi, |
Here is what I did with a PIC and a small lamp....

Hey Thanks! I found the Nuts and Volts article at parallax.com. This
is what I'm looking for but I don't know about microprocessers and
stamp modules...this is a very interesting possibilty though....The PIC
has potential too. but I would like to adapt it to LED's and really
don't know hao to do that or programming the PIC. Is there any
possibility of a lower tech solution? I'll keep on looking!
Thanks again!

What size are we talking here Greg?
You can buy those candle-shaped light globes that run on mains power with a
simulated flame already inside it. Should be able to get it from a local
lighting specialist.
