Avões Open_Source, Repoarar Madeira, e Tricorders

Porque não? Avionetas Open-Source, eis algo de novo... E recorrendo à Fabricação 3D, para ser ainda mais acessível!



Makerplane aims to create the first open source aircraft

By David Szondy

The idea of owning your own plane is the stuff of daydreams. It’s incredibly appealing, but despite some (relative) drops in pricing in recent years, it remains incredibly expensive. If you build your own plane from a kit, it’s a bit cheaper than buying one, but the odds are that you’ll never complete the job because kitplanes are notoriously difficult to build. However, that may be changing. MakerPlane is a project that aims to create an open source aircraft designed by contributors and built with digital manufacturing processes. You can’t download the plans into your 3D printer and fly away that afternoon, but it does hold the promise of making amateur aviation a lot more accessible.





Eis algo mais terra-a-terra, reparar as rachas na Madeira, de forma a que mantenham as tábuas as propriedades originais...


Repairing Split Wood

Scotttland

In an otherwise attractive piece of wood, an unsightly split or crack can run deep like family turmoil.  Most wood fillers are intended to be little more than aesthetic solutions.  Even the hardiest fillers are intended to withstand compressive forces but not sheer stress.  Here I will demonstrate my solution for when I don't want to give-up on a piece of wood.  This block was salvaged from a eucalyptus tree that fell on my grandmother's house (don't worry, I'm fine).  I want to be able to work on it without risk of further splittage.
  I do all my wood repair at TechShop.

Lembram-se do Caminho das Estrelas, Star Trek?

Eis um passo para o Diagnóstico em poucos instantes, de várias Doenças, e condições ambientais de Higiene:  

 

"Real-life tricorder" to be tested on International Space Station

By Darren Quick

While still impressive, the capabilities of early "tricorders," such as the Scanadu and Dr Jansen's tricorder, fall well short of the Star Trek device that inspired them. But new technology to be tested on the International Space Station (ISS) brings the age of instant diagnosis of medical conditions using a portable device a step closer. The Microflow could also make its way into doctor’s offices here on Earth where it might help cut down on the number of follow up visits required after waiting to get results back from the lab.
The Microflow is a miniaturized version of a flow cytometer, which analyzes cells suspended in a stream of fluid as they pass single-file in front of a laser. As the suspended particle passes through the beam, various detectors positioned where the stream meets the laser can analyze the physical and chemical properties of the molecules or cells in the stream. Because they work in real-time, flow cytometers offer diagnosis in just 10 minutes of everything from infections, to stress, blood cells and cancer markers. They can also identify bacterial pathogens in food or water.
