Windell Oskay at Evil Mad Scientist Laboratory shows us how to make a snap-o-lantern sure to scare the bajeezus out of trick-or-treaters. A clever use for those mini-pumpkins that bounce around our house every year for sure! Plus, it is a good excuse to delve into microcontrollers. There is still time folks, there is still time. For me, alas, there is none, being in the final stages of making two costumes for the geeklings this year that incorporate fleece, vinyl, motors, and liquid. But the snap-o-lantern is giving me all kinds of ideas to work in moving parts for next year’s pumpkin carving!
