Candle flicker algorithm and hardware

[phile]

I was looking at some of those battery operated candles that flicker like real candles, and asked myself, "how hard would that be to make?" The main problem being, I have very little knowledge of electrical engineering. Even if I had an algorithm, I wouldn't know how to implement it into hardware.

I thought it would be neat to make my own, and just hollow out real candles.
How complex is the problem of creating such a device? Does the hardware have to be made custom for the algorithm?

Where can I start?

There was a nice article in Nuts&Volts covering both some theory and construction of electronic candles.

Perhaps their website might have it available.

Neat, i'll have to check it out.

It appears the link is broken when I do a search on their site. When I check out the cached page by google, it's just a short paragraph telling the reader that the candle circuitry info is in that particular issue.

Here's one. I wonder how big this circuit would be...

There is always the library.
