Flickering LED Candle for Chandelier

[mrpugowski]

I have 24 points for candles on a chandelier, and want to simulate a flickering candle, can anyone reccomend a way of lighting this using LED?
What kind of transistors or random current generators are reccomended or is this really the way to go?
Any help appreciated
Thanks
Andrew

That is beyond my expertise, however, using a pmm and changing the timming should produce what you are after.

You might contact an administrator and have this moved to the batteries and electronics section. I bet you would get more ideas and help there.

You're gonna want to go with microcontroller+power transistor+LED. Pretty simple, if you can get the microcontrollers coded or code them yourself.

I read somewhere that a lot of the LED flickering candles actually re-use cheap sound chips from those "singing" greeting cards as pseudo-randomness sources. The way to test it is to see if the pattern repeats on power-up. I tested that with two sibling LED tealights from the same batch; sure enough, when powered on at the same time, they flickered in unison.

So, a project for the curious: find a way to determine what "song" is in your candle

Has anyone tried listening to what's recorded? Maybe it's some creepy message. That would also be an awesome ways for spies to do a dead drop... record a message in the candle.

This is just a guess. A repeat cycle timer ( I use one as a way to turn my misting system on for 1 sec. every 60 sec.)

They are many choices of timing (some quite short) and you could use more than one(set up differently) to get a chaotic range of flashing.

I would be aware that not all drivers are rated for flashing.

Might not get the effect you want.

Hope this helps.
