Case #95: Dick Keeps His Home Fires Burning

NO RATINGS

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.
