Uma Impressora 3D de alto detalhe, e notícias da Comsol

Da Itália, vem esta nova Impressora 3D de Secretária, e promete uma muito maior resolução, reparem que ao lado do Objecto impresso, está uma moeda de 1 Cêntimo!

Desktop 3DLPrinter offers high resolution at a high price

Jason Falconer

Digital Light Processing (DLP) is the method of choice for the next generation of personal 3D printers. The DLP process prints objects with a very fine resolution that surpasses that of typical Fused Filament Fabrication (RepRap) printers which extrude molten plastic layer by layer. An Italian company called Robot Factory has created the latest prosumer printer. If judged by appearances alone, the 3DLPrinter would be one of the more attractive 3D printers we've seen – but can it measure up to its competition? 

Like most 3D printers, the 3DLPrinter outputs sliced STL files at a minimum X/Y resolution of 50 microns, and a minimum Z resolution of 1 micron. However, this is somewhat difficult to verify as the example objects have a layer thickness of 50 microns and 100 microns. If it can actually print at 1 micron in the Z axis, it would qualify as one of the most accurate printers available today.

Robot Caterpillar Tank Treads, Johnny Five Style - 3D Print 

Tomdf

When I was but a wee little inventor, I saw a movie that forever imprinted itself into my soul. This picture told the gripping tale of mans' ever loosening control over its own technology; a film that dared ask the question "What makes us alive?" This masterpiece of the cinema was, of course, Short Circuit 2.

During November of 2012 I was fortunate enough to play as an Artist in Residence at the Instructables HQ, and was given full access to a room full of Object Connex 500 multiple material 3D printers! I had always wanted a toy version of the robot from Short Circuit, Johnny Five, and I found myself with the means to print one at my fingertips. Later on I will be adding components to this robot until I have a completed, functional model.

To begin, I drew a handful of rough pencil sketches just to give myself a an idea of how the treads could work and eventually moved the idea over into 123D beta 9. A copy of the model was printed, and the pieces of track snapped together just as intended.

Parallel Leg Vise with St. Andrew's Cross 

Scotttland

  In woodworking and fabricating, a leg vise can be enormously useful.  They offer a large, flat clamping surface on which you can impart a surprising amount of clamping force.  A properly aligned leg vise can hold large workpieces such as doors or 6x6 beams.  But few companies make proper woodworking leg vises or even the hardware for them.  The issue with making a leg vise is keeping the chop (the part that moves) parallel to the bench leg when under tension.  This Instructable features a solution.

  I make all my leg vises at TechShop.

Exercício para os Tarecos! 
Cá vai esta ideia para que os vossos gatos se exercitarem, agora que chove e faz frio, e nem dá para eles saírem:

The Cats Tower 

thattori

The design concept of the cats tower is all-in-one-cage which is narrow for human being, but wide for cats. In the all-in-one-cage, cats can eat, can do exercise, can do excretion and can sleep in the cage.
Those are [1]high curiosity to environment, [2]high mobility and [3]high ability of self decision. The high curiosity to environment brings out high ability to move, and the high mobility brings out high ability of self decision. The curiosity is the path to the mobility, the mobility is the path to the self-decision. The three features are genetically pre-installed within cats, I guessed so.
Cats can't stop learning of environment. The curiosity is expressed as [1]freely exploration, [2]freely research or [3]freely strolling. It looks like action gathering information for keeping their own life.

Thermite fire-fighting robot removes firefighters from harm's way

David Szondy

Howe and Howe Technologies of Waterboro, Maine, has unveiled the firefighter of tomorrow called the Thermite RS1-T2. Based on technology developed for the U.S. Army, this squat little modular robot on tank treads is a small, powerful fire fighting machine that provides crews with a means for remote reconnaissance and fighting fires in hazardous areas safely.

The Thermite is designed to be used in areas of extreme hazard, such as aircraft fires, refineries, chemical plants or nuclear reactors. In fact, brothers Mike and Geoff Howe, who founded Howe and Howe, used the Fukushima nuclear disaster as an example of the kind of location where the Thermite is intended to be used. Not only is it preferable to risk a robot instead of a person, the Thermite is also immune to smoke, fumes and fatigue – the last of which is a major cause of death in firefighters by heart attack.

E enquanto cá, se desprezam os Inventores, e se deixou morrer a APC, na América, diz-se "Inventors are the lifeblood of our country and economy". 
Assim é que é!
Cá, em Portugal, são só umas Tiradas Bacocas sobre "a Inovação"...
Vejam só o que é uma Cultura com Sentido Prático:

2012 DaVinci Inventor Showcase 

Inventors are the lifeblood of our country and economy. The strength of our nation has been due in large part to the ingenuity of inventors. They use their hands to fashion the components, their minds to create function and strategy, and their hearts to feed the passion that drives their work forward.
In tough economic times, inventors bring hope and inspiration to everyone they touch and have the potential to bring exciting new jobs along with them.The inventions being unveiled at this event are a powerful force. In fact, our future is being created inside the minds of these inventors. They live a life of passion and dreams, driven by a desire to make our world a better place.
The 8th annual DaVinci Inventor Showcase is a rare opportunity to meet inventors, feel the intensity of their spirit, touch their creations, and experience the transformation as they step us from the here and now to a better tomorrow.

Mindsets é fenomenal.
À vossa disposição, Kits Didácticos impecáveis, e uma Fonte de Alimentação ajustável que dá para tudo, 200W, Muáháháhá!

Solar Concept Vehicle 

This amazing solar-powered model has been designed for Mindsets by product designer Neal Turner - whose work took centre stage at the 2012 international Kinetica exhibition. Neal has designed a concept vehicle, of which this is the working model, to demonstrate that wheels can function using rim bearings rather than a conventional bearing at the centre (hubless wheel). The model itself was originally conceived as an executive toy, but we think the styling can provide design inspiration for pupils and, at the same time, illustrate the creative potential of the laser cutter. Powered by a single solar cell, the beautifully engineered and detailed vehicle comes as a kit of parts that can be assembled in approximately 30 minutes. The model is powered by a single solar cell that stores energy in a supercapacitor. When the capacitor is charged, it is simply switched over to drive the motor.

200W Adjustable Power Supply

A regulated 5~15V power supply with current limiting from 0~15A. With an LCD readout showing the voltage and current supplied, it can also be used to charge Lead Acid batteries.

Features:
• Input Voltage: 220~240V AC
• Output Voltage: 5~15V DC Regulated
• Current Rating: 0~15 Amps
• Output Connections: 4mm Sockets / Clamp

E o Brasil voa alto... A terceira maior Fabricante de Aviões Comerciais é a bem Brasileira Embraer!
E criaram emprego em Portugal!
Toma e embrulha!
Com estes nossos Irmãos, é que estamos bem, a CEE, dá cá o pé, é só tangas.

Com tecnologia de ponta, Embraer é o orgulho da indústria brasileira

Empresa brasileira é a terceira maior fabricante de aeronaves comerciais e é apontada por especialistas como líder tecnológica no segmento até 120 passageiros.

A recente abertura de duas fábricas da Embraer na cidade de Évora, no sul de Portugal, deverá resultar na criação de 600 empregos diretos e 1.200 indiretos. O investimento total da empresa brasileira é de 177 milhões de euros.

Com as novas fábricas, Évora deverá se tornar uma referência internacional em tecnologia aeronáutica de ponta, avalia o jornalista especializado Jens Flottau. Ele lembra que a Embraer é uma referência mundial no setor. O novo modelo militar KC-390 deverá ser, ao menos em parte, construído nas novas instalações em Évora.
