Lego e mais Lego no Campo Pequeno

por Elisabete Silva

Ao entrar, o difícil é decidir por onde começar. Três milhões de peças de Lego compõem cidades, monumentos, naves espaciais, comboios... É a maior exposição em Lisboa do género que promete atrair crianças e adultos.  

O T-Rex tenta dominar a praça do Campo Pequeno, mas o seu tamanho rivaliza com o tigre, o urso ou o camelo (que pesa 500 quilos). São sucesso garantido por serem vistosos, mas é nos pormenores que está o mais apetecido na exposição que hoje abriu portas.
Na cidade espacial nada falta. Naves, comboios, radares, com direito a movimento para dar mais realismo. Mas numa cidade mais "real", também é impossível não se ficar perdido em tanto pormenor, cada um correspondente a horas e horas de trabalho.

MIT students turn whole building into huge game of Tetris 

By Paul Ridden

 The two-hundred and ninety-five feet (ninety meter) tall Building 54 on MIT's Cambridge campus has become the canvas for a number of carefully planned and daringly executed visual displays over the years, not strictly allowed by the administration but often looked upon with some appreciation. The building is home to the Institute's Department of Earth, Atmospheric, and Planetary Science (EAPS) and has a host of meteorological instruments and radio communications equipment on its roof - but its the grid-like windows to the front that have become the main attraction to hackers, as they are known. The latest hack is the successful realization of a long-standing challenge, a huge playable game of Tetris.

Make Your Own DIY CNC

This instructable outlines the assembly process of my 2nd generation CNC machine which I designed to be simple to build and quiet enough to be apartment friendly. I have included example projects that I have made in the first two weeks of using the machine to demonstrate its capabilities.

This is the second CNC machine that I have designed and built. My first machine was based off of oomlout’s instructable “How to make a Three Axis CNC Machine (Cheaply and Easily)” (by far my favorite instructable and the one that got me hooked on the site). It was moderately successful, cutting a number of parts from foam (a summary of parts made can be found on my abandoned blog here along with some build photos). The lack of overall stiffness and play in the linear mechanisms meant that plywood and plastics could not be cut effectively. The biggest downfall of the machine was the difficulty to setup and square the axes and lacked the ability to make fine adjustments once set up. The drive pulleys were sandwiched between the gantry sides and if a pulley loosened the entire gantry structure had to be disassembled and put back together and squared all over again (a couple evenings of work).

3-D Printing Hits Rock-Bottom Prices With Homemade Ceramics Mix

ScienceDaily (Mar. 31, 2009) — This story is, literally, stone age meets digital age: University of Washington researchers are combining the ancient art of ceramics and the new technology of 3-D printing. Along the way, they are making 3-D printing dramatically cheaper.
About five years ago, Mark Ganter, a UW mechanical engineering professor and longtime practitioner of 3-D printing, became frustrated with the high cost of commercial materials and began experimenting with his own formulas. He and his students gradually developed a home-brew approach, replacing a proprietary mix with artists' ceramic powder blended with sugar and maltodextrin, a nutritional supplement. The results are printed in a recent issue of Ceramics Monthly. Co-authors are Duane Storti, UW associate professor of mechanical engineering, and Ben Utela, a former UW doctoral student.
"Normally these supplies cost $30 to $50 a pound. Our materials cost less than a dollar a pound," said Ganter. He said he wants to distribute the free recipes in order to democratize 3-D printing and expand the range of printable objects.

rhinoreverse

rhinoreverse is plug-in software for the CAD-system Rhinoceros©. The purpose is to create spline-faces based on given mesh of point data. The user interactions have been reduced on sketching the boundary curves for the new faces. All calculations will be done automatically. This leads to a very simple and intuitive handling. One big advantage is the option to represent large complex shapes by a few faces.

Watch the Movie to get an idea how to start.

rhinoreverse enables the user to transform digitised surfaces (point meshes) to spline faces. The goal is to prepare further design steps of the CAx-process-chain like solid modelling and NC-programming.
Additional a so called "healing" algorithm was implemented. Already existing NURBS-poly-face models can be improved: Small gaps, steps and overlaps will be filled automatically. The goal is to improve data quality in order to enable solid-modelling and NC-milling.

Festo's SmartInversion flying contraption turns itself inside out for propulsion

By Jan Belezina 

Festo, a German automation technology company that brought us, among other things, the smartbird robotic seagull and bionic flying penguins, has built a flying object unlike any we have seen. Despite the impressive biomimicry track record, this time its engineers decided to look for inspiration in the inanimate world of geometry. Based on a geometrical band first created by Swiss artist and inventor Paul Schatz, the SmartInversion is filled with helium and propels itself through the air by constantly turning itself inside out. By investigating this pulsating, rhythmical movement, called inversion, the company hopes to identify possible uses for it in technology.

Self-assembling plastic nanofibers present cheaper alternative to carbon nanotubes

By Antonio Pasolini


French researchers have produced highly conducive plastic fibers with a thickness of only a few nanometers that self-assemble when exposed to a flash of light. The tiny fibers (one nanometer equals one billionth of a meter) could become a cheaper and easier-to-handle alternative to carbon nanotubes and play a role in the development of electronic components on the nanoscale.
Researchers from the Centre National de la Recherche Scientifique (CNRS), an organization funded by the French government, and the Université de Strasbourg say the fibers combine the properties of metals and plastic organic polymers, which are commonly used to conduct electric current, and see applications in several fields ranging from electronics to architecture.
Lead researchers Nicolas Giuseppone and Bernard Doudin now want to demonstrate that the plastic fibers have the potential to be integrated into products such as flexible screens and solar cells.

Plasma Display Steampunk

This was a week-end project I created from a 6" black and white TV and a large neon bulb a friend sent me from overseas,
the smaller bulbs I found at a second hand store, I wish I didn't have to say this, but this project uses VERY HIGH VOLTAGES,
it uses the out put voltage of the TV's flyback I'm not sure the exact voltage but I'm guessing around 20,000 volts, it can burn, cause a heart attack and is just plain miserable.

12 volt air conditioner

To build a 12 volt air conditioner or body cooler you will need mostly the same items.. -flexible hose and clamps -12 volt bait well pump (I bought the 500 gph model, way over kill on the flow rate but cheap) -wiring -cigar lighter plug -largest cooler you can fit in the area it will sit. (air conditioners are rated in BTU's, the smallest ones for sale cheap are the 5,000 BTU ones, house and larger ones are rated in tons, this air conditioner will depend on how much ice you can put in it) I found the "marine" coolers the best for what I needed as they tend to be all white (less solar heat gain) and much more rectangular with less bulk (takes up space) mine also has large easy to hold handles (easy to strap into the seat belt in the car, and easy to carry full of ice and water) it also has an external hinge, most hinged lid designs have a air leak around the hinge, the external hinge type have a lid that will lock in place even if you remove the hinges. -zip ties

Calligaris introduces the use of "Liquid Wood" to its furniture collection

By Bridget Borgobello

During Milan Design Week 2012, Italian furniture maker Calligaris has introduced a chair made from Liquid Wood, a composite biomaterial consisting of polymer and wood. It is said to be 100% recyclable, and is produced with raw materials that are easily available and renewable.

Liquid Wood is molded like a normal thermoplastic polymer, reportedly allowing for versatility and high performance in terms of durability, resistance and flexibility. The material is mainly composed of lignin and cellulose, which are found in the cells of plants.

Já há quem pense em minerar os Asteróides, e porque não, se eles lá estão, à nossa espera?

Is asteroid mining about to begin?

By Brian Dodson

Planetary Resources, a new player in the commercial space industry, is backed by a host of tech and aerospace luminaries with an integrated personal net worth on the far side of US$30 billion. A press release from the company hints that it will look to establish asteroid mining operations in space.
The President and Chief Engineer of the new company is Chris Lewicki, president of Arkyd Astronautics and former NASA Phoenix Mars Lander mission manager. A press release states, "the company will overlay two critical sectors – space exploration and natural resources – to add trillions of dollars to the global GDP. This innovative start-up will create a new industry and a new definition of natural resources."
Various Internet sources speculate, based on this statement, the name of the company, and the past interests of some of the officers and investors, that Planetary Resources will be aiming toward asteroid mining, probably with a strong robotic slant. Some types of asteroids are profligate ores of the noble metals, such as gold, platinum, iridium, and rhodium, and thus ripe for exploitation.

Fabricating a Heavy-Duty Rocket Stove

Rocket stoves are small efficient stoves that can produce a hot flame with only a few small pieces of wood. The reason it is called a rocket stove is because when wood is added to the fire the flames create an internal draft. As the draft is created, the fire begins to produce a jet of fire coming through the stove pipe. The stove flame eventually becomes so hot that it produces very little smoke. The stove should be able to produce a hot continuous flame that will lick the bottom surface of a pot or pan placed on top of the stove.

Self-sculpting smart sand could assemble itself into solid replicas of objects

By Jan Belezina

Research currently underway at MIT’s Distributed Robotic Laboratory (DRL) could lead to an innovative replicative manufacturing technique with the disruptive potential equal to that of 3D printing. Imagine a sand-like material that could autonomously assemble itself into a replica of any object encased within. Incredible though this may sound, the DRL researchers have already managed to build a large scale proof-of-concept, with 10-mm cubes acting as the grains.

Before we go into how these cubes - or "smart pebbles" - work, let’s sketch out the general concept. The idea is to create objects using a subtractive method, where excess material is removed just like when carving in stone. Each grain of smart sand would be a self-contained micro computer. These tiny machines would use an elaborate algorithm to communicate with the neighboring particles in order to establish the exact position and shape of the input object so that it can be replicated.

Open source resin 3D printers in development

Hobbyists work on affordable resin printing tech

After posting about Junior Veloso’s resin 3D printer last week (and its higher-than-expected price), commenters arthur and Adam B. pointed to a couple of cost-sensitive open source projects in the works: Lemon Curry and an unnamed printer by Christopher Jansen.

Both are still in the experimental stage, but expect to deliver low-cost, open source solutions that any person should be able to put together and get running. In the case of Jansen’s printer, his running tally of costs is under $200, including a used DLP projector from eBay.

Unmanned nanomaterial Piranha threatens to redefine naval warfare


By James Holloway

You've heard of UAVs, unmanned remote controlled military aircraft; but what about USVs? Standing for Unmanned Surface Vehicle, a USV is quite simply an unmanned boat, like Zyvex Marine's Piranha concept. We've looked at USVs before, and the Piranha specifically in early 2010; but what was then a prototype under development is now a fully-fledged production craft, having shipped its first unit last November. "Our production facility is closer to rocket science than traditional boat building," says Zyvex Marine VP Byron Nutley of his boat - the only one in the world, it's claimed, that is made out of nanomaterials.

Compound found in red wine could help fight obesity


By Bridget Borgobello

Researchers from Purdue University in Indiana are testing a compound found in red wine that has the ability to block the processes of fat cell development. The research into the compound known as piceatannol may lead towards finding a simple method to combat obesity.
Piceatannol results from the conversion of resveratrol – a compound found in red wine, grapes and peanuts that is also thought to combat cancer, heart disease and neurodegenerative diseases. When resveratrol is converted into the piceatannol compound, which naturally occurs after consumption, the compound has the ability to delay fat cell growth.

Atenção, a Inovação 3D também fala Português, eis o Brasileiro Júnior Veloso, e uma máquina comparável:

Fundraising begins for Junior Veloso’s resin-based 3D printer

Long-awaited project aims to raise $300,000

Well, it took a bit longer than the post last month indicated, but Junior Veloso’s awesome-looking resin-based 3D printer is now taking preorders.

Since the project will need a certain minimum amount of interest to be practical, the preorders are being done in the form of an Indiegogo campaign. (Indiegogo is similar to Kickstarter, but with more flexibility in funding and location terms.)

Here’s how the main campaign levels break down:

– $599 Basic Kit I

Software, controller board, schematics/plans

– $1,999 Basic Kit II

Above, plus motors, linear actuators, power supply, building tray, building head

– $3,999 Full Kit

Above, plus DLP projector, 1kg of resin, assembly tools

Tutorial: Gears & Joints with SketchUp and SketchyPhysics

Continuing my commitment to using free software even though it drives me up the wall sometimes

Following my recent obsession with drawing machines, I’m working on a new project with lots of gears and linkages. I figured it would be a good time to learn how to do mechanical modelling in SketchUp. Sketchy Physics is a plugin for Google SketchUp that allows you to simulate mechanical models. It is very capable but also very frustrating!

A Sculpteo tem este novo Material para Impressão 3D, Alumide, um Compósito de Plástico e Alumínio:

Alumide

Alumide is a blend of polyamide and grey aluminium dust. Strong, slightly flexible material that can withstand some pressure when bent. The surface has a grainy, sanded appearance and is slightly porous with shiny aluminium dust on it. 

Technology

Alumide objects are produced by laser sintering of alumide powder. The models are printed layer by layer by a laser that draws the object in the powder, by solidifying the material. Layer thickness is 0.1 mm and the minimum size of visible details on the model is 0.5 mm. Minimum wall thickness for this technology is 1 mm. Alumide is more rigid than regular plastic. This material is convenient for complex models and moving parts. Maximum size is 308 x 308 x 600 mm (12.1 x 12.1 x 23,6 inches).

• Matte Grey
• Strong
• Convenient for complex models and moving parts

New technologies detect seizures, and could possibly even eliminate them

By Ben Coxworth

Seizures can be very scary experiences for people who suffer from them, especially since they may sometimes result in the need for medical attention. Unfortunately, they often come on so fast that the people getting them aren’t able to get out a call for help beforehand – they simply have to ride out the seizure on their own, and hope for the best. Now, however, two new technologies may be able to help.

A wearable alert device

The watch, known as the SmartWatch, is made by California-based tech company SmartMonitor. It can be worn 24 hours a day, and detects repetitive, excessive arm motions outside of the user’s regular movement spectrum, associated with grand mal seizures.

A system to stop seizures

At Baltimore’s Johns Hopkins University, meanwhile, assistant professor of biomedical engineering Sridevi V. Sarma is leading research into software that could more efficiently stop seizures before they happen.

Currently, when people are prone to seizures that don’t respond to drug treatment, they sometimes have electrodes surgically implanted in their brains. Algorithms running in an accompanying electronics package monitor the brain’s electrical activity, and cause the electrodes to administer a electrical pulse to the brain, when seizure-like activity is detected. While this setup is often effective at stopping the seizure from proceeding, it is also very prone to false alarms.

Em Àreas onde falta tudo, eis uma maneira de desinfectar as mãos, por Plasma, que elimina Bactérias... Que é uma limpeza!

Battery-powered plasma flashlight makes short work of bacteria

By Darren Quick

An international team of scientists has created a handheld, battery powered device that has been shown to effectively rid skin of bacteria in an instant by blasting it with plasma. The plasma flashlight, which shouldn’t be confused with a plasma torch that will damage much more than bacteria if used on the skin, could provide a convenient way for paramedics and military personnel to deal with harmful bacteria in the field.

The self-contained device is powered by a 12 V battery and doesn’t require any external gas feed or handling system. The plume of plasma it generates is between 20-23°C (68-73.4°F), so it won’t damage the skin. It is also fitted with resistors to stop it heating up and becoming too hot to touch. Its creators say it can also be easily manufactured at a cost of less than US$100 per unit.

Não tem muitos usos Médicos, mas muitos usos na Oficina, um Aquecedor por Inducção:

30 kVA Induction Heater

Induction heaters are used to heat conductive materials in a non-contact process. Commercially, they are used for heat treating, brazing, soldering, etc., as well as to melt and forge iron, steel, and aluminum.
This Instructable will walk you through the construction of a high-power (30kVA) heater, suitable for melting aluminum and steel. Note that to take full advantage of this design, you will need a 220V outlet, at least a 50A single-phase one and preferably a 50A or 60A 3-phase outlet
