Ligar qualquer coisa à Net? E um Guia para Impressoras 3D Profissionais, Makers pró Espaço, e Fibras para casas.

Eis a ùltima da littleBits, como liguar tudo à Internet, com o cloudBit, para realizar os sonhos de tanto Engenhocas, para ligar tudo em casa, testar protótipos, registar dados em qualquer lado, etc:

We're extremely excited to announce the arrival of the cloudBit, the newest addition to the littleBits library. The cloudBit is the most powerful product we’ve ever engineered. Now you can use the littleBits library to connect the physical world to the internet. Recreate the most popular internet-connected devices, use littleBits to prototype the next billion dollar idea, or invent a project that solves your own, unique problem. Whether you're a designer prototyping a new smart device or a family inventing a way to feed the pet fish from vacation, the cloudBit just opened up a world of limitless possibilities!

Querem entrar no mundo da Impressão 3D Profissional? 
Eis como o fazerem com este Guia, uma página impecável da Sculpteo, que vos explica tudo, tintim por tintim...

 Guide to Professional 3D Printers
There are over 100 industry-grade 3D printer models currently on the market. These printers are large, commercial 3D printing machines intended for professional use. At Sculpteo we exclusively uses professional 3D printers.
We’ve put together a guide to these industrial 3D printers based on a selection of printers from each manufacturer that best represents the range of options out there — from price to materials to build size.
We hope this guide will help you determine the best 3D printer for your business needs. And don’t forget, you don’t have to buy your own printer to have access to professional quality 3D printing. Sculpteo offers an online 3D printing service using a variety of the printers listed in this guide.
Note on pricing: Because commercial 3D printers are sold through third-party, licensed resellers, there is not a standard retail price for each printer. Prices are only available via a quote from one of these resellers. We have recorded the pricing below based either on a quote from a reseller that asked to stay anonymous or from another online source (with a link).
The guide is organized by printer technology. For details explaining each process, check out The Different Technologies Behind 3D Printing.

Space: The Final (Maker) Frontier

Andrew Back

A look at three relatively low cost routes to getting your electronics project into space.
There was a time — not that very long ago — when if you wanted to get a functional piece of electronics into space it took an obscene amount of money and a few hundred tonnes of volatile rocket fuel. Suffice to say that, unless you were part of a national space programme, a global telecoms company or an evil supervillain, you were probably out of luck.
Thanks to ever smaller and lower cost technologies, coupled with a burning desire to get in on the action and a healthy dose of inventiveness, this is all changing — and at a somewhat rapid pace. This post takes a look at just a few of the options available for getting your project into space.

E esta Técnica cabe na Categoria de "porque é que ninguém pensou nisso, até agora?"!!!

Todos conhecem o Algodão Doce, mas podem-se utilizar Fibras de toda a espécie, para construír Estruturas leves e rápidas de fazer!
Até se poderá pensar em máquinas CNC para sabe-se lá mais o quê!

Spraying natural fibers to build cotton-candy surfaces

Zoe Romano

During Fab10- Fab Festival in Barcelona I met Jin Shihui who introduced me to CandyProject, a research project exploring the process of spraying natural fiber to create a non-woven textile that can be used to produce anything from building components to ornamental artifacts.
By means of air pressure we separate the fibers from a roving allowing them to self-organize and reassemble due to the surface tension caused by a fine mist of adhesive. This creates a controlled fibrous aggregation producing an emergent morphospace encompassing the initial substructure.
The robot Jin is holding in her hands in the picture above uses air pressure to separate fibers into individual strands. While the fibers are still separated they are embedded with an adhesive spray and all parameters are controlled within the robot  with an Arduino Uno:
