O MIT não pára, notícia cortesia da Ponoko, eis Painéis Solares feitos por impressão em papel:
MIT unveils Solar cells that can be 3D printed on ordinary paper, plastic or fabric
The new printing process uses vapors, not liquids, and temperatures less than 120 degrees Celsius. These “gentle” conditions make it possible to use ordinary untreated paper, cloth or plastic as the substrate on which the solar cells can be printed.
In order to create an array of photovoltaic cells on the paper, five layers of material need to be deposited onto the same sheet of paper in successive passes, using a mask (also made of paper) to form the patterns of cells on the surface. And the process has to take place in a vacuum chamber.
Uma pequena maravilha, notícia na Ponoko!!!
The teeniest cabinetPushing pixels on a scale that makes the Nanocade look positively giant, this miniature Space Invaders arcade cabinet faithfully reproduces that classic retro gaming feel down to the smallest details.
Constructed from 6mm MDF, the unit houses a modded Game Boy Advance SP and features a tiny joystick alongside arcade-style buttons sourced from eBay. The GBA innards are accessible through a magnetically attached rear panel, so that cartridges can be swapped out for some gaming variety if those Invaders get too much for you.
Click through to see some gameplay action in a video where Victor, the man behind it all, talks through a few of the quirks of his miniature construction.
