The startup company Occipital launched a Kickstarter campaign for their new device—the Structure Sensor. What is it? It’s a gadget that works with your iPad to turn it into a 3D scanner. The Structure Sensor is a bracket-style clip that fits over your iPad and uses its own infrared sensor and black-and-white camera (for depthperception) as well as the iPad’s own camera. Occipital CEO Jeff Powers says there’s a lot you can do with it. Scan and print replacement parts, or use it to create replicas ofthings around you. Act fast though! Be one of the first to pledge $329 and you get the full kit by December. After that, the price tag jumps up to $500 and you have to wait til February.
