Daniel Burnham, Anuj Patel, and Sam Bell created for their embedded systems class at Georgia Tech a bathroom mirror / information display. Dubbed Cloud Mirror, it is essentially a partially silvered mirror placed in front of an LCD television, hooked up to a WinCE box with some Phidget sensors.
The User controls the display by waving his/her hand across eight infrared sensors (four across the top, and four down the side). Swiping across the top. the display is toggled on and off, while various modes (weather, news, traffic, and calendar) are controlled through the sensors on the right side. (Video after the jump.) Obviously, it is prototype level technology, but is a bit interesting. Basically, they were thinking about how to integrate typical morning information gathering into daily grooming rituals.
Ying Liu, et al. from Michael Dickey’s Lab at North Carolina State demonstrate how simply using an inkjet printer to put black lines on shrinky-dinks, one can transform them into a heat activated self-folding material. (Paper.)
The idea is very simple. When a light is shone on the taped up shrinky-dink, the black tape absorbs more energy, and thus the area under the tape heats up faster than the uncovered material. Since shrinky-dinks contract when heated, a hinge is created. By varying the width of the tape, the rate of closure and the resultant angle can be controlled.
While the men fell as well, apparently they didn’t fall nearly as much. These are supposed to be some of the best dirt bike riders in the world, they look like what I could do, and I have never ridden a dirt bike in my life. The sexist youtube comments write themselves.
In case you’re wondering, the event is called Enduro X, which is basically just indoor dirt bike racing with bigger obstacles.
