Uma Impressora 3D por menos de 200 Dólares! E como fazer Caixas em Acrílico, um Lança-hamas de bolso, e um Microscópio a partir duma Câmara!

Esta impressora 3D pode ser barata, mas não é nada, nada má... 50 Microns de altura mínima de Camadas?

É muito bom!

Feito por uma Firma que já fabricava componentes para as outras Impressoras 3D, isto é feito por quem sabe...

E para a Malta do Arduino, é mesmo bom, porque a Electrónica é baseada no Arduino, é um Kit Open Source, o que quer dizer que é perfeitamente possivel, vocês personalizarem a coisa.

QU-BD One Up: A 3D printer for under US$200

Darren Quick

The home 3D printing revolution has picked up pace in recent times with printers such as the MakiBox and Buccaneer making 3D printing increasingly more affordable. Although not as cheap as the homemade LEGObot, the QU-BD One Up is claiming the title of the world's cheapest production-ready 3D printer with a price tag of under US$200.
Already manufacturing and supplying parts for more than 20 3D printer companies, such as DeltaMaker, the folks at QU-BD took the next obvious step and decided to produce their own 3D printers. Joining the company's existing Revolution, Revolution XL and RPM Rapid Prototyping Mill are the One Up and Two Up units that boast a build area of 100 x 100 x 125 mm and 175 x 175 x 125 mm, respectively.

Snap-fit plexiglas case for your project

andrea biffi

Months ago I've built a thermostat to control my electric oven temperature (and cook meringues).
You can read the related instructable here.
Meringues are still waiting, but now my device has a new plexiglas case, with snap-fit joints and hexagonal grill for the ventilation.
I designed the box in Autocad with the right measures to contain the thermostat and all the components required to be connected to wall plug and oven.

Pocket-sized Multicolored Flamethrowers and Sorcerer Staff  
Don Juan De Pyro

In case no one told you flamethrowers are really dangerous. This is NOT an instructable for kids! This is for educational purposes and if you attempt this you are doing so at your own risk. I am not responsible if you get hurt attempting this. The responsibility for your safety depends on you! I try to discuss how to do this safely throughout the instructable so, READ EVERYTHING CAREFULLY, but realize I can't think of every safety problem. HAVE A FIRE EXTINGUISHER HANDY! If you do not have a high level of understanding of the chemistry or physics involved you really should not do this.

That said, science and learning without danger would yield no cars, no fireworks, and no disease cures. So, I'm going to donate my body to some dangerous science!

New technique to print ink-based electrical circuitry using a desktop printer

Randall Marsh

Researchers at Georgia Tech have developed a new technique to print advanced, ink-based electrical circuitry on a desktop printer. Using about US$300 worth of off-the-shelf equipment, the researchers were able to print arbitrary-shaped circuits on resin-coated paper, PET film, and glossy photo paper with silver nanoparticle ink.
Printing circuits isn’t entirely new, but the team’s technique makes the process faster and cheaper. Similar to graphene-based printing done at the Max Planck Institute, Georgia Tech's method uses empty ink jet cartridges, except it does not require heating for ink placement.
Initiated by the University of Tokyo and with Microsoft Research contributing to the concept, Georgia Tech took the reigns of the project building on its materials and circuit design expertise previously seen in the creation of paper-based sensors for explosives. The team was able to print ink-based circuits in as little as 60 seconds.

SafeFlame torch turns water into fire

Ben Coxworth

The pressurized acetylene and propane gas used in brazing and related tasks is highly flammable, and thus very dangerous. You know what isn't flammable, though? Water. Bearing that in mind, the European Union-funded SafeFlame consortium has developed a torch system that generates a flame using nothing but H2O and electricity.
SafeFlame utilizes an electrical current to electrolyze ordinary water, separating it into hydrogen and oxygen gas. Those gases are then mixed and ignited as they exit the torch's nozzle. By fine-tuning the proportions of the two gases, different types of flames can be produced for different applications.

Experimenting with the Pi NoIR prototype and blue and infrared filters.

Following on from my first attempt at building a night vision time-lapse rig, I thought I'd see how the Pi NoIR performs when used with filters. Of course, you get pretty interesting results just using the camera in daylight and without any filtering; as can be seen below images have a reddish hue and infrared reflecting plants appear curiously radiant..

India starts countdown for Mars mission

David Szondy

India has started the clock on its most ambitious space project to date. On Sunday at 6:08 IST, the Indian Space Research Organisation (ISRO) began the countdown for its Mars Orbiter Mission (MOM). If all goes to schedule, the unmanned probe will lift off on Tuesday from the First Launch Pad at the Satish Dhawan Space Centre (SHAR), on the island of Sriharikota at 2:38 pm IST atop a Polar Satellite Launch Vehicle (PSLV-C25), marking the point where India hopes to launch itself into the space-faring big leagues.

Da KJMagnetics, eis mais umas dicas sobre Magnetismo, aqui, a Lição é sobre a Direcção das Linhas de Força num Campo Magnético, e como os Ímanes de Neodímio são magnetizados:

All About Magnetization Direction

What do we mean by a magnet’s Magnetization Direction?  Why do we care about this?  Can a magnet’s magnetization direction be changed?  What’s the difference between axially and diametrically magnetized magnets?  How can I tell them apart?  Why can’t I get a block magnet magnetized along the length or width?  What magnetization direction should be used with directional sensors?

What do we mean by a magnet’s Magnetization Direction?  Is it important?

The strong magnets found at K&J Magnetics are called sintered neodymium magnets,.  They are the most powerful type of permanent magnet available.  Sintered means the metal is pressed together at high temperatures in a very specific way to make a strong magnet.  You can learn a bit more about this process in How Neodymium Magnets are Made.

Discovery shines a light on potential cure for Alzheimer's and Parkinson's

Darren Quick

It is generally believed that aggregations of proteins are responsible for brain disorders such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease. However, the difficulty has been in detecting the aggregates responsible and removing them from the brain. Researchers at Chalmers University of Technology in Sweden and Polish Wroclaw University of Technology have found a potential solution using lasers.
Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease are thought to be caused by aggregates of amyloid beta protein that start to inhibit proper cellular processes in the brain. Although it is technically possible to cure the diseases by detecting and removing the amyloid protein aggregates using chemicals, these chemicals are highly toxic and harmful to the patient.

Ya know what’s really aggravating? You put many hours of sweat and labor into producing a nice fireworks display, perhaps with some homemade aerial fireworks shells and fountains, and somewhere in the show you fire some of these simple and easy-to-make Cremora fireballs. And after the show, do you hear much praise for the meticulously constructed shells that you slaved over? No! All you hear, especially from the kids, is, “Wow, we loved those big, fiery things! Whaddaya call em? They were hot!”

High Quality (and Safe) Copper Plating 
A_Steingrube

There are a few copper electroplating methods on here, but they are either dangerous, provide very low quality results, or cost an arm and a leg.  Your plated object should be a brilliant, shiny red and not blackened and your pocket book shouldn't be hit hard by chemical costs or hospital bills.

The method I am writing about here is the copper acetate method.  Rather than buying copper acetate pre-made, we will make it ourselves.


I wanted this instructable to be as easy as possible, safe as possible, and as cheap as possible.

Copper plating has a variety of uses.  Aesthetically, it can be used to create a steampunk look on otherwise ill-fitting metals. Anodizing the object after plating can create brilliant, multicolored objects. Electrically, it creates a highly conductive surface for soldering or use in AC circuits (for the skin effect). It is also frequently used to prepare stubborn materials for other platings such as nickel and silver down the road.

DIY Miniature Thermometer 

Enjoying Electronics

For just a couple of bucks and a few components you have laying around your work area you can build a min thermometer than fits in your pocket. The whole circuit sits nicely right on top of a 9v battery, and is connected to it with double sided tape. Changing batteries was never so easy!

Now I must say that the code is just kind of a example code. I've been getting a lot of criticisms on my sketch and I can see why. It wasn't efficient or practical.  I really didn't know how to go about this. Before I made the project I posted several question in the i'ble forums and the Arduino forums but I didn't get an answer so using my beginner coding skills I managed this code.  If you want to make your own code that is much better I would love for ya'll to show me how to make the code better!

Auto-Defesa! E um Simulador de CNC, nova versão, como enviar para a DesignShare, e uma Cortadora CNC de Vinil e Cartão!

Livros de Auto-Defesa, há muitos, mas só este é da Co-Autoria do nosso grande amigo, Inventor, Jornalista, Advogado Agente de Patentes, e Escritor, José Roberto Abrahão.

E como seria de esperar, ele lembrou-se, sendo Inventor, de coisas que outros não!

Como o Enquadramento Legal dos actos de Auto-defesa, para que saibam com o que contar... Ou como se defender... NUMA CADEIRA DE RODAS!

Eis o Inventor, numa Entrevista da Bueno Editora:

José Roberto Abrahão fala sobre o novo livro de defesa pessoal

“Não seja mais uma vítima”, publicado pela Bueno Editora, aborda a violência urbana e como os grupos minoritários podem se proteger. 

O livro “Não seja mais uma vítima”, escrito por Ricardo Nakayama e José Roberto Romeiro Abrahão, tem como finalidade suscitar a questão da violência urbana e promover uma cultura de paz por meio da defesa pessoal. Nesta entrevista exclusiva, Abrahão, um dos criadores do SOTAI, explica quais as medidas podem ser adotadas para reduzir o problema e os pontos fortes da obra. MASTER: Não seja mais uma vítima tem como objetivo contribuir para uma cultura de paz. Sendo assim, quais são as medidas que podem ser adotadas no dia a dia para que o cidadão não se torne refém do medo? ABRAHÃO: De nada adianta se queixar e dizer que a culpa é do governo ou de outros órgãos públicos, pois a premissa básica para que alguém seja atendido pela polícia é ter se tornado vítima da violência. Para não se tornar um alvo de criminosos, é necessário adotar medidas preventivas. Em minha opinião, baseada em mais de 30 anos de experiência profissional junto a vários segmentos da segurança e criminalidade, atitude e preparação valem muito mais que verba e equipamentos indistintamente utilizados. Como é impossível falar sobre todas as vertentes da violência e das suas contra-medidas, vou exemplificar com um ícone de segurança da nossa sociedade: o carro blindado. Hoje, as pessoas sonham com um carro blindado. Elas pensam que andar num "carro à prova de balas" fornecerá a tão sonhada liberdade. Com isso, poderão jantar fora, ir à balada, viajar, isto é, viver "a boa vida". Em contrapartida, se esquecem que, como uma arma de fogo, faca, cartão de crédito, telefone ou um lápis, o carro é apenas um objeto inanimado, incapaz de agir por conta própria, e pode mesmo vir a se voltar contra seu dono por conta de imperícia, imprudência ou negligência. Frequentemente, pessoas são assaltadas em seus automóveis blindados na hora que entram ou saem deles, rodarem com vidros parcialmente abertos, portas destravadas ou quando estão comprando os mais diversos produtos nos semáforos, exibindo carteiras durante as transações. Diante disso, cabe perguntar: para que usam um veículo blindado?
