Case #95: Dick Keeps His Home Fires Burning

Design News Staff -- Design News, December 10, 2006

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.

Light Matters: The Unsung Heroes of Modern Health Care
First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
