polyethylenimine (PEI) is an organic polymer, inherent in the process of detergent, cosmetics production, or employed as a wet-strength agent in paper-making process. however, the ingredient is most known for its capability of removing carbon dioxide, which has led to its use in the porous components of space aircraft interiors. while looking for the best and most permeable structure to impregnate polymer with, the scientists discovered that fumed silica is the most efficient material in terms of its absorption rate. once it is full of the chemical compound, the process can be reversed: heating the material to 85° C produces high-concentrated air (2 to 5% CO2), which could be used next to make methane or during the farming.
very interesting tool for technological urban permaculture
The team from the Monterrey Institute of Technology (ITESM) in Mexico designed an experimental new walking stick. Packed with high tech, it will be synchronised with a virtual map inside the stick and a GPS system so that it knows when the person is off course.
Researchers have put a charge into sticks that buzzes for up to three seconds if the user fails to turn when they should. Blind people are being shocked with electricity (2 milliamps) to make them go in the right direction.
The charge is connected to the user’s vestibular system, which is located in the inner ear and deals with balance and movement.
Alfredo Victor Mantilla Caeiros, a professor of mechatronics at ITESM, said that it was 99% accurate in tests so far.
Unlike apps which have been developed for the blind it does not interfere with other senses like touch.
a new visualization system developed by MIT researchers, combines ceiling-mounted projectors with motion-capture technology and animation software to project a robot’s intentions in real time. (Learn more about the system: http://bit.ly/1thQBSQ) The researchers say the system may help speed up the development of self-driving cars, package-delivering drones, and other autonomous, route-planning vehicles.
looks like the MIT is going to get itself some Google funding on that one - but it might already be the case :)
HuddleLamp uses our free and open source computer vision software to continuously track the presence and positions of devices on a table with sub-centimeter precision. At any time, users can add or remove devices and reconfigure them without the need of installing any apps or attaching markers. Additionally, the users’ hands are tracked to detect interactions above and between devices.
a great potential for mobile gaming and collaborative work
Google has launched a new cloud platform in Germany called Open Roberta, as the internet giant looks to simplify “programming for small robots.” With Open Roberta, Google is looking to... Keep reading →
school projects of the 21st century. Exciting time to be a kid and make the best of it
Drawing Robot uses edge detection to reproduce an image. It's got a little bit of Arduino and a dash of MATLAB coding. But most importantly, you'll be making a robot that draws, which is incredibly cool.
Stop-motion animator Dillon Markey works on projects for animation powerhouses like Robot Chicken and PES. While on set three years ago Markey tired of moving back and forth between the set, camera, and computers for each shot and conceived of a numerical keypad he could use to help control some, if not all, of the devices he uses for animating.
He could have done it with other tech as his need is rather simple BUT the Power Glove is FUCKING AWESOME :)
Less measures the storage conditions of your silo bag 24 hours, 365 days a year. It helps monitoring through a smartphone app and notify you against any deviation from moisture, carbon dioxide concentration and / or temperature inside.
It is also a monitoring system that detects potential theft at the time they are happening because it monitors the movements of the silo.
interesting tech that could easily be modded for other monitoring within a 2.0 farm
For each Soundscraper, 84,000 electro-active lashes would cover the metal frame and pick up noise from cars, trains, pedestrians and passing planes. Each of the lashes is armed with sound sensors called Parametric Frequency Increased Generators. Once the noise is picked up, an energy harvester converts the vibrations to kinetic energy. Transducer cells then convert the energy to electricity, which is stored or distributed to the grid for regular electric use.
The team estimates that just one Soundscraper could produce 150 megawatts of energy in a densely populated city, which roughly converts to 10% of the lighting needs of Los Angeles. The clean energy would also help the city reduce carbon emissions and reliance upon fossil fuels.
Mind blowing architectural innovation. They do look ugly, but isn't it the case with most skyscrapers anyway. AT least, they're good for something!
To hear Google's designers explain it, material design is more than a redesign. It's an effort to establish best practices for the fledgling field of interactive design as a whole.
That's ambitious... and Google ambitious tech revolution often fail because of the lack of relevant communication about the benefits (remember Google Wave). Here it's no different, I know it's powerful stuff in some extent, but I fail to see concretely why :)
The Kano kit wants to make computing as easy as playing with Lego. Does it succeed?
Not only this project introduce kids to coding, but it also allows them to understand how a computer / OS work. They can make their PC their own and it's something most adult don't ever come across. Great tool.
L'imprimante 3D GO est la petite dernière des ateliers de Portabee, un fabricant né en 2011 à Singapour. Dimensions de 20.8 x 22.5 x 7.9 cm. Pour autant, le volume d’impression n’est pas en reste et permettra de fabriquer des objets jusqu’à 12 x 16 x 12 cm.
Dronecode started as 3D Robotics' free/open codebase for UAVs, and it has grown to the point where it has flown off on its own, with a formal, community-run board and an ambitious roadmap for the future.
