HOW TO – Make a realistic electronic flame flicker

The latest Gadget Freak, holiday style! –

Give your Christmas lighting a country look and make your Nativity scene more realistic with an electronic flame flicker. This device can be used as a lamp dimmer or a flame flicker simulator, and may be switched on and off with the switch on a lamp. The flicker dynamics may be customized for candle, kerosene (or oil) lamp or campfire. Replacing the controls with fixed resistors yields a version inexpensive enough to build an array of them for independently flickering electric candles.

    Flickering fire and smoke is certainly what you will get if you use the 200V recommended rated parts outside the US (on a 240V mains system).

    You can also build digital candle-flicker simulators. A couple years ago I wrote one that runs on an AVR, based on the (much more sophisticated) project on Philip Ching’s webpage. An ATmega8 can run a good several candle simulations simultaneously: all you need to do is filter an LFSR’s output with a low-pass filter (running average with the correct weights will do it) and PWM a pin with the result.

    (While hunting down that page just now I also found this useful Producing Flicker With Software page.)
