They are a function of the instant atomic arrangement, how we arrange the atoms: same composition, simple example, one inch thick pine board, one inch thick plywood.
John Kestner and David Carr created Twine, a 2.5 inch-square device with on-board temperature and vibration sensors, as well as an expansion connector for other sensors, such as moisture sensors and magnetic switches, all tightly integrated through WiFi with a cloud-based service.
As for the rest of the specs, they include a 1.2GHz dual-core processor, a 4.3-inch capacitive touchscreen, 16GB of on-board storage, 1GB of memory, and an 8 megapixel camera 'round back that's paired with a 3 megapixel front-facing cam.
Carrying a 4 x 4-inch form factor between a Raspberry Pi and mini-ITX board, it'll be equipped with a Core i3 Ivy Bridge processor, HD 4000 graphics, two SoDIMM sockets, an mSATA slot for an SSD drive, three USB ports, one HDMI port and a mini-PCI slot for wireless connectivity.
