LEDs flicker and shimmer randomly like a candle flame or fire LED or bulb flickers and shimmers randomly like a candle flame or fire.  HOME


This may well be the world's only discreet logic circuit to generate truely random output. It makes an excellent candle flicker light for your haloween pumpkin, and looks much more authentic than a shimmer light wherever a good a simulated flame effect is required. It flickers even more authentically than a candle in a light breeze.

Here is a 120VAC hot chassis version of the above circuit. This is the one I use to run my pumpkin every haloween. Note that the AC line provides the low frequency oscillator waveform.
