Flicker Lamp - Having bought a cute little ‘paraffin lamp’ from a cut price shop,
I decided to make it a little more interesting. Its battery powered of course but its
continuous shine and simple on / off ‘wick control’ did not make for anything like a
close simulation of the real thing. So, I replaced the on / off control with a
variable potentiometer and I added flicker!.....(added 04/04/04) |

Flickering Fire Effect - This simple circuit uses four low-Wattage colored bulbs
and four fluorescent lamp starters to make nice flickering flame effect. (added 4/02) |
|
Flickering Fire Light - This may well be the world's only discreet logic circuit
to generate truly random output. It makes an excellent candle flicker light for your
Halloween pumpkin, and looks much more authentic than a shimmer light wherever a good
a simulated flame effect is required. I do not guarantee the accuracy or safety of any
information herein. (added 2/05) |

Heart of LEDs - One of the requests we received after publication of the Christmas
Star was "can you do different shapes?" Well, with Mother’s Day coming up soon, we
thought a heart would be appropriate. Now you can have something different to give to
that special Mum or Grandmother. or you may be able to redeem yourself if you forgot
St Valentines Day! Either way, the Heart will certainly last a... (added 4/05) |

Heart-shaped Badge - The badge consists of eight LEDs arranged in the shape of a
heart. One LED is lit at a time and this 'chases' round the shape. It would be easy to
adapt this project to create other shapes with the eight LEDs.....Designed by John
