Makerbot é agora da Stratasis! E um Livro sobre Impressão 3D, Renesas, e uma Catapulta Viking!

No que esperemos que signifique Impressoras 3D mais baratas, e à venda em todo o lado, a Stratasis comprou a Makerbot:

Makerbot Acquired by Stratasys

Makerbot has been acquired by Stratasys, a 3D printing business, and will merge with a subsidiary of the company, the two companies announced Wednesday afternoon.
“The last couple of years have been incredibly inspiring and exciting for us,” said Bre Pettis, CEO of Makerbot, in a statement. “We have an aggressive model for growth, and partnering with Stratasys will allow us to supercharge our mission to empower individuals to make things
using a MakerBot, and allow us to bring 3D technology to more people."

E a magnífica RepRap Magazine, traz-nos uma data de coisas boas, como esta notícia, uma iniciativa da que vos oferece um Livro que responde às vossas perguntas sobre Impressão 3D Low-cost:


The book, titled “Low-cost 3D Printing for Science, Education and Sustainable Development”, offers a practical guide to this rapidly evolving technology, giving an overview of current research on the topic and its uses in science education. It was compiled and edited by ICTP’s Science Dissemination Unit (SDU) and can be downloaded free of cost from the website
The affordable and easy-to-use technology is good news for developing countries, where 3D printing could open up exciting opportunities for research, education and humanitarian projects. As an institute dedicated to promoting sustainable science in the developing world, ICTP is prepared to advance the adoption of this technology in these regions. The book’s editors -Enrique Canessa, Carlo Fonda and Marco Zennarowant readers to understand and explore the huge potential that 3D technology provides.

Uma notícia da Designspark, têem agora à vossa didposição mais um Micro-Controlador de alto gabarito, o Renesas, que podem adquirir por quase nada, para avaliarem o bicho:

Ultra Low Power Microcontrollers with High Performance - Renesas RX200 MCU

Renesas RX200 32-bit microcontrollers deliver more performance on far less power than other MCUs whilst operating over wide voltage ranges, and offer huge power savings in standby.   With a common architecture to the RX600 100MHz family theses MCUs meet the needs of the most demanding engineers.
Very low cost evaluation boards are available.

E acabamos por hoje, com esta incrível Catapulta Viking, que podem construír, para este verão, e as vossas Guerras de Balões de Àgua, Muáháháhá!

Viking Catapult

In this step by step tutorial I will be showing you how to make your very own Homemade Viking Catapult!
You will need 5 sticks that are are 4-6 feet long with a diameter of 1-2 inches. I am using 4 foot long sticks. The 2 shorter sticks you need will be 2-3 feet long also with a diameter of 1-2 inches. I am using 2 foot long sticks. You will need all of the items shown in the picture. You will also need something that will make a hole about 1/2 an inch wide, such as a drill.
Another thing you will need is approximately 60 inches of elastic band that has a diameter of about a half of an inch. Another thing you will need is some sort of bowl of cup to use as the holder for the item you will launch. Pictures of these items come later in this instructable.
