PUMPKIN SAFETY LIGHT

摘要

Light your Halloween Jack O' Lantern with this flickering LED circuit. Every Halloween, my children and I would carve a variety of designs and figures on to our pumpkins. At night, we would insert candles and watch the light flicker in the cool night air. When the children were young, I would light the candles for safety and on Halloween night make sure that the pumpkins were out of the trick-or-treaters way, so that their costumes would not get too close to the candle flames. As always the children would want their pumpkins to be lit several nights, and after the second night of having a lit candle, the pumpkin would get soft and take on an overripe smell. As an engineer I knew there must be an electronic alternative to a lit candle, and there is. I call it the Pumpkin Safety Light.
