Solidoodle, Mindsets, e muito mais

Solidoodle vem na 3ª Versão, esta bem mais capaz de fazer o que querem em grande: 


Third-gen Solidoodle 3D printer pumps up the volume

Darren Quick

Over the past couple of years, the number of consumer 3D printers hitting the market has multiplied like … well, like plastic chess pieces churned out by a 3D printer. For its latest unit, Solidoodle has upped the build area to 8 x 8 x 8 inches (20 x 20 x 20 cm), which is two extra inches over the printable dimensions of the Solidoodle 2. This more than doubles the build volume from 216 in3 (3,540 cm3) for the Solidoodle 2 to 512 in3 (8,390 cm3) for the new Solidoodle 3.

Um Meta-Material, que age como uma Lente, e uma Lente extremamente precisa, para as Ondas de Rádio! Eis algo que vai dar que falar, nos mundos tanto da Rádio, como do Wi-Fi...



MIT produces new metamaterial that acts as a lens for radio waves

David Szondy

We expect the world to be predictable. Water flows downhill, fire burns and lenses bend light in a particular way. That worldview took a jolt as Isaac Ehrenberg, an MIT graduate student in mechanical engineering, developed a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision. That may not seem too disturbing, but the lens is concave and works in exactly the opposite manner of how such a lens should.
Metamaterials have an air of magic about them. The elements they’re made out of should work one way, but they way they’ve been fabricated make them operate in another. They are ordinary substances that have been engineered with precisely designed and fabricated microscopic structures. These structures interact with light or sound in such a way that they produce effects that are not found in nature. In the case of the MIT metamaterial lens, they result in a concave lens that should spread radio waves, but focuses them instead.





...E que tal Músculos Artificiais, com 85 vezes a força dum Músculo normal, do mesmo tamanho?
Parece coisa de Ficção Científica, mas isso já é normal, hoje em dia, tornar ideias fantásticas, realidade...
E com Nanotubos , e Parafina, sim, da vulgar Cera, das Velas!
Valha-nos Deus!

Wax-infused "nanoyarn" used to create artificial muscles

Adam Williams

An international team of scientists based at the University of Texas, Dallas (UTD), has developed a new type of artificial muscle created from carbon “nanotubes” – tiny hollow cylinders constructed from the same graphite layers found in the core of a standard pencil. Despite measuring 10,000 times less than the diameter of a human hair, the new muscles can lift more than 100,000 times their own weight, which amounts to approximately 85 times the power of a natural muscle of equivalent size.
The new muscles are manufactured by taking a twisted yarn of the miniscule carbon cylinders, then introducing a volume-changing “guest,” in this case the paraffin wax used in candles.

Geo Data Logger: Arduino+GPS+SD+Accelerometer to log, time-stamp, and geo-tag sensor data

UPDATES
  • NOV 19: I have added a section with code to make this prototype act as a plain GPS logger without any sensors. 
  • NOV 19: I can confirm that the program for this project works with Arduino IDE 1.02. The problems I had earlier were a result of loose wiring. 

INTRODUCTION

I thought it would be educational to build a prototype that I can take on the road to log, geo-tag, and time-stamp sensors data to be analyzed later with mapping and data analyses applications.  So I figured why not start with a gadget that can log road conditions. This prototype, the Bump-O-Meter, measures road conditions by using an Arduino, a GPS receiver, an SD card, and an accelerometer sensor.

This prototype is a generic sensor logging/geo-tagging gadget which means the accelerometer can be replaced with any other sensor(s) to log anything anywhere. 

As a matter or fact my next adventure with this logger is to replace the accelerometer with a pollution sensor to visualize levels of air quality around town.
