It was 18 years ago this month that Daft Punk released their first studio album, Homework. The electronic-music duo's robotic persona recently inspired Pedro Ruiz, creative technologist at Adafruit, to do a little homework of his own. It took Ruiz three days, and enough plastic to stretch the length of three football fields, to 3-D print a replica of Daft Punk's trademark helmets. For extra pizzazz, he added programmable LEDs. Even non-fans can enjoy the helmet, Ruiz says: "It's great for scaring your small child when they act up!"
