Every so often there comes around a neat little DIY project that can be both fun and educational. If you don’t know much about circuitry, this halloween project might be the thing that finally moves you from gadget user to gadget maker.
The project is to create a light-sensitive jack-o-lantern that turns itself off during the day and comes alive during the night with two glowing LED eyes. All you need is a phototransistor, several transistors and resistors, LEDs and some AA batteries(plus holder). The detailed list can be found at the Evil Mad Scientists website.
Of course, placing something you just made into a goopy mess of a pumpkin might not be too appealing to you. But you can always buy a fake pumpkin from a craft store so that you only have to do this once but get years of use out of it.
