A new design from an Australian high school student aims to solve both problems at once: While the device purifies wastewater, it uses pollutants in the water to boost power production in a separate compartment. 17-year-old Cynthia Sin Nga Lam, one of 15 finalists in this year's Google Science Fair, started researching renewable electricity generation last year, and quickly realized that she could incorporate water purification into her process. Her prototype, called H2Pro, is a portable device powered only by sunlight. Dirty water goes in one end, and a titanium mesh, activated by the sun, sterilizes the water and sends it through an extra filter. Building Open Source Hardware: DIY Manufacturing for Hackers and Makers: 9780321906045: Computer Science Books @ Amazon.com. 21 Technologies That Will Decentralize the World. Across the planet, new technologies and business models are decentralizing power and placing it in the hands of communities and individuals.
"We are seeing technology-driven networks replacing bureacratically-driven hierarchies," says VC and futurist Fred Wilson, speaking on what to expect in the next ten years. View the entire 25-minute video below (it's worth it!) And then check out the 21 innovations below. Thanks to Jenny Ryan whose Open Garden newsletter inspired this post. Here are 21 innovations that will help make it happen: 1. Decentralized technology will become mainstream in 2014, according to the Open Garden Foundation, a San Francisco-based startup dedicated to net neutrality and internet access for everyone. 2. Commotion Router is free, open source software that allows for communities to build their own mesh networks. 3. Do you really want to trust your data to Twitter?
4. The future of devices is micro and wearable. 21 Technologies That Will Decentralize the World. Meet the Man who built a Hoverbike with Sacred Geometry. Now, I know by now you might be tired of me talking about Sacred Geometry.
“Pattern of the Universe” blah blah blah “Keys to unlocking the secrets of the reality” yada yada yada… I get it. It can get pretty out there sometimes… Which is actually why this article and video is so important. You’re about to see what happens when you merge Sacred Geometry with our Modern Scientific Approach, coupled with a strong engineering mind. Today, you’re about to see Sacred Geometry harnessed for the power of flight. Más allá del wearable: 4 casos de gadgets implantados en el cuerpo. The Isoscel-Ease Drawing Robot.
Maybe you’ve built your own drawing robot, but I doubt it comes with a geometric pun like the Isoscelease pen plotter device.
As the name would imply, this robo-plotter uses a constantly varying isosceles triangle that is able to angularly expand and contract as well as move as a unit back and forth. This allows for an innovative way to move in the “X” and “Y” directions. One limitation is that this plotter doesn’t have a way to pick the pen up, however, as seen in the video below, it can still draw a beautiful image. To drive this motion, a servo motors powers a belt drive for each of the two arms. As noted on Darcy’s page, the belt is in tension, while the linear rail that it rides on is compression, giving nice rigidity to the design.
Currently, work is being done to generate pen paths for portraits using Processing.org. Jeremy Cook. Printrbot Reveals CNC Router. A prototype of Printrbot’s new CNC machine.
The final model will be constructed of folded and machined metal. (Photo: Dave Hays) Printrbot Founder and CEO Brook Drumm was on hand at MakerCon today to reveal a beta of the upcoming Printrbot CNC router. While it’s targeted as a tool for beginner CNC’ers, the machine is quite capable for maker-pros alike. It can cut wood, plastic, and aluminum at “respectable speeds,” according to Brook.

Chica UTEC. Para poder conseguir que el vapor se reparta por toda la figura, y no solo por la parte inferior, utilizaremos un ventilador, que permitirá repartir el calor por todo el recipiente.
De esta manera, conseguiremos acabados como los que se muestran a continuación. El proceso de acetonado para la mujer es tan simple como el que se muestra a continuación: En el vídeo se muestra como simplemente se echa la acetona dentro del recipiente y el propio vapor va consumiendo la superficie de la misma. Evidentemente, dependiendo del tamaño de nuestra pieza y la forma que esta contenga, el calor le afectará más o menos a según que puntos de la misma.
Por ello, si nos apoyamos con la ayuda de un ventilador, este puede repartir de manera ecuánime el calor por el interior de todo el recipiente, sin dejar que el calor solo afecte a los puntos más bajos. No debemos olvidar, que si lo que queremos es no perder tanto los detalles superficiales, existen dos opciones:
