Halloween is officially here, and if you´re still scrounging for ideas with precious few hours until the march for candy begins, we´ve got you covered. Entries have been pouring in to our DIY Halloween Instructables contest, and whether you´re fashioning a costume made entirely of pumpkins or wiring up a USB-powered jack-o´-lantern, one thing´s for certain-Halloween really brings out the DIY spirit in everyone.
Launch the gallery to check out a handful of terrific ideas, ranging from the divine to the disturbing. And if you´ve been too busy in the workshop to share your most elaborate Halloween build with the world, there's still a week left to enter our contest[link] over at Instructables for fabulous prizes and plenty of All Hallows glory. Happy Halloween!
