Seasonal? Maybe.
In keeping with the occasion (albeit somewhat late - the server lost my
previous posts), here's something for lighting up the Jack O' Lantern. Most of the components are mounted directly on the negative end of the AA cell. A stiff wire soldered to the positive nipple is used to stand the light up inside the pumpkin. With a teaspoon of water inside the pumpkin to improve conductivity, enough current will flow when the open end of the 220k resistor touches the surface to light the amber LED to 30mA. Used 10 hours on Hallowe'en night, an alkaline cell should last 3-5 seasons. QS My LED circuits: http://quantsuff.com |

Not just the circuit, but the concept, too. Also, that's some excellent pumpkin carving. Is that John Lennon I see? Thanks for posting. Tom |

The stencil can be found at http://www.fabulousfoods.com/holiday...umpplans2.html. I just zoomed the image on the monitor and traced the outline. I also did Buddy Holly but it did not turn out well at all. Here's a closeup below. QS |

I haven't carved a Jack O'Lantern in years, but maybe I'll give it a try next season, following your inspiration. Very cool stuff! Tom |

How did you draw the "seasonal" schematic on the image? Ed Can you post a pic of it again? For the circuit imprint, start with a 'negative' (white on black) image of the schematic and 'OR' it to the base image. A breeze with Photoshop, but doable on Thumbsplus, which is what I used. QS |
