The other night at a restaurant I became fascinated watching one of those flickering white LED electronic "candle inserts" because I couldn't sense a regular pattern to the flicker rate changes.
It would flicker rather regularly for a while at a rate of about once a second then occasionally change to a more rapid flicker rate for a bit and then go back to the slower flicker rate.
The times it spent in the two different flicker rates didn't seem to be very regular.
It reminded me somewhat of a neon lamp near the end of its life.
Anyone know what sort of circuitry is employed in those gadgets? I rather doubt that it's based on a random number generator?
Thanks, Guys,
Jeff
