Except for maybe the addition of child-safe power tools, not much has changed in decades when it comes to carving a Jack-o-lantern. But if you want Halloween to be about more than gutting a pumpkin and sugar rushes, LittleBits has come out with a simple kit that turns a Jack-o-lantern into a lesson about basic electronics.
The aptly-named $29 Hack-o-lantern kit includes a battery power module, an LED module, and a sound trigger module so that your child's (or your) Jack-o-lantern comes to life and glows at the sound of trick-or-treaters. It's a simple hack, and while your kids are assembling the simple circuit they'll be too distracted to start a pumpkin guts food fight. Worth every penny. [LittleBits via Engadget]
