At this point you're used to gesture control on your devices — your smartphone, your tablet, the trackpad on your laptop — but true gesture-based communication with a device shouldn't rely on placing your hands on a surface. With Nod, gestures are freed from the confines of touch, letting you control just about any connected device by simply moving your hands in the air. By placing the ring on your finger, you can type without ever touching a keyboard, turn down the thermostat using your nest, even play a song on your phone without any physical contact. Made from jewelry-grade stainless steel, and available in a range of sizes to fit your finger, it uses Bluetooth connectivity to interact with a growing range of devices and technologies — you may never touch another device again.
Interested in getting into 3D printing, but not eager to fork out the cash necessary for a costly printer? All you need to take advantage of the artistic and creative possibilities with 3D printing is the Lix 3D Printing Pen. While it may not afford you the structural rigidity of items printed from a full-fledged printer, you can still draw incredible structures and sculptures as easily as placing a pen to paper. And as the smallest 3D printing pen available on the market, you don't need to worry about handling clumsy tools every time you want to make something.
