Timo Arnall, who, together with Jack Schultze brought us a touchless Rube Goldberg machine based on RFID back in 2009, has teamed up with Jorn Knutsen and Einar Sneve Martinussen to produce Immaterials: Light Painting Wi-Fi, which is a project that visualizes wireless network signal strength in city areas using a custom-built 4-meter measuring rod equipped with LEDs and conventional light painting techniques.

Ring flashes are often used for macro and glamour portrait photography, but that kind of professional equipment can be quite expensive. Wolf made his own using a bundle of fiber optic strands originating at his camera’s flash and terminating at an acrylic ring he cut himself.

You might know them for seemingly ridiculous innovations like Segway shoes or the HRP-4C pop star robot, but the folks at AIST have put away the gimmicks for their latest invention -- a full-color night vision camera. Produced by Nanolux, an arm of AIST, the camera uses a series of algorithms to read and process wavelengths reflected by objects lit with infrareds, allowing it to successfully reproduce reds, blues, and greens in the darkest of conditions. The company hopes to make the device available by the end of 2011 at a price point lower than conventional night vision cameras, and says they will work with different lenses to improve long-range photography for the device. Such an invention could have serious implications for fields like surveillance and wildlife observation, but fear not, AIST hasn't lost its sense of humor -- the company used a Bullwinkle figurine rotating on a Lazy Susan to demo its latest invention at Printable Electronics 2011. Check out the video after the jump.

Simple and satisfying craft technique from Photojojo: Take pictures of your favorite object, print them at 1:1 scale on inkjet canvas, and sew them together to make a hollow cloth facsimile of the real thing. Use it as a pouch or slipcover that advertises what it contains or, alternately, conceals it. [via CRAFT]
