Formcard! Mais o novo Raspberry Pi, Armações 3D, a Impressora 3D Tetrix, e Micro-motores

Eis algo para ter sempre no bolso, Plástico termo-moldável, para reparações, Moldes, bases para o Smartphone, e tudo o que calhar! 
E numa placa bem maneirinha, que cabe no bolso da camisa:

Melt, Mold, Make, Mend  
FORMcard is a handy, pocket sized card of meltable bio-plastic. Simply drop it in a cup of hot water to make little solutions to everyday problems. When it's cool it's really strong like nylon, so you can make solid durable solutions with it, and then you can reheat it again and again to adapt, change and reuse it. Because it's a convenient card size, you can keep one in your pocket, wallet, kitchen drawer or tool box so that it's there whenever and wherever it's needed.
A great benefit is that when it's very hot, it sticks to some other plastics, so you can actually use it to instantly fix say.... a favourite plastic shovel when you are on holiday.
(please remember that hot water and hot FORMcards should be handled with GREAT care as either can scold you. Very hot FORMcards are sticky when they first come out of the hot water and can also stick to wooden surfaces. Work on a ceramic plate and if in doubt about using it, let it cool down first, you can always heat it up again later on!)
FORMcard is designed and developed by Peter Marigold and launched on Kickstarter on the 11th November 2015. It was successfully funded on the first day and completed the campaign with 816% funding and more than 2000 backers. It will soon be fully commercially available around the world. 
It would be great to connect with you on social media where we will be posting updates as the project develops by clicking on the links at the bottom of this page. 

O Micro-computador Raspberry Pi vem com 10 vezes mais potência que o oroginal(!), e Wireless LAN e Bluetooth, é só verificar as capacidades cada vez maiores desta pequena maravilha:

Raspberry Pi
A small, powerful and lightweight ARM based computer. 
Introducing the new Raspberry Pi 3 Model B, the latest member of the Pi family. Delivering up to 10x the processing performance of the original Raspberry Pi and added connectivity with 802.11 b/g/n Wireless LAN and Bluetooth 4.1. 
The new board is not only great for learning to programme, gaming and hacks it’s now perfect for IoT projects too. 

Eis algo de interessante, peças de canto para fazerem as vossas próprias Armações, de Impressoras 3d, Fresas 3D, ou lçá o que seja...
Feitas por Impressão 3D!

Há mais barato, há mais caro, mas não há, é mais Didáctico.
Uma Impressora 3D para a Educação, que a brincar, a brincar, faz os alunos aprenderem CAD, Electrónica, Programação, e Técnicas de Construcção, ficando-se com uma Impressora 3d, por Bónus!

Ficam ainda a saber, se não sabem, que a Tetrix, é um Jogo de Contrucção, como a Meccano, mas muito mais preciso, tão mais, que serve para montar destas Impressoras! 

TETRIX 3D-Printer
The TETRIX 3D-Printer was designed as an educational tool for middle and high school technology students, robotics teams, and adults. The purpose of constructing the printer is to train people's building, tool usage, electronics, CAD, and programming skills with a single project. You also get a 3D-printer once you're done!
The printer design is based on TETRIX parts, which are designed by PITSCO and used in the FIRST Tech Challenge robotics competition. The printer also utilizes elements of various RepRap printer designs, such as the Printrboard control system. The design is completely open-source, so feel free to personalize and alter your printer.
The overall cost of the printer is about $640, and the educational value is priceless! The majority of the cost is attributed to the TETRIX parts, but the high accuracy of the pre-drilled, pre-sized aircraft-grade aluminum saves time and reduces error, which outweighs the price.

E cá vai Dica, para terminar por hoje, estão sempre a perguntar onde é que se arranjam aqueles micro-motores dos Quadracópteros de ter por casa, pois aqui está um Link para os poderem comprar, à fonte...
