Three siblings and one GameCube is a recipe for territorial skirmishes. Many games only support two users. Jeremy Willden bought his three kids a GameCube for Christmas and quickly discovered parental intervention was critical. He initially used a kitchen timer, but soon opted for a more technology-driven solution. He created an electronic Time Turner. The gadget uses a Microchip microcontroller connected to three LEDs and a small speaker. Every 15 minutes, the LEDs change (each labeled with a child’s name) to indicate whose turn it is.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
