Carpintaria enquanto Arte, Uma Câmara vídeo, um Sistema Lego-compatível, e uma Targeta LED

Eis uma dica do Blogue L'Air du Bois, sobre um Carpinteiro Inglês que desdenha as Ferramentas Eléctricas, e entre um mundo de coisas, vejam-no falando sobre a Arte, como só fala, quem a ama:

The Art of Ancient Hands
Paul Sellers
A Chisel 1/16” slides into pine like a hot knife into butter. Mortising holes is not always for large work. Many years ago a customer brought hundreds of rosewood parts to me in a cardboard box. It was a multifaceted Chinese lantern made up of frames that housed painted glass panels. Each meeting point intersected with mitred tenons into mitred reception mortises on the adjacent stiles. The owner had missing parts by the dozen, but in the scheme and scale of things, what was missing seemed very small.


Eis uma pequena Câmara Vídeo, com muito que falar...
Dica da Red Shark, esta pequena maravilha vai fazer justiça às vossas Demosntrações de Protótipos, sem compromissos, porque tem resolução para isso, um Sensor de 1 Polegada trata bem do assunto:

New Sony X70 - a 20 megapixel 4K-upgradable XDCAM. Our first hands-on report 

Sony has this week announced a small XDCAM camcorder with an unusually high specifiation - which will be extended to 4K with a future upgrade
The world contains a lot of small, handheld camcorders. They're often especially small and hand-holdable now we're beyond the point of including a tape mechanism and the only moving part is often in the lens. Sony's new PMW-X70, therefore, enters a crowded field, and needs some genuinely interesting specifications to distinguish itself.
Perhaps the most arresting development in the X70 is the sensor – the same one-inch chip as has already been deployed in the FDR-AX100 and in at least one of Sony's compact stills cameras. This technological convergence is no great surprise, although this is the first time we've seen  the sensor married to a 4:2:2 10-bit recording system, which should be as able as anything to demonstrate the successes – and failures, if any – of the imager.


Para aprender Robótica a brincar, que é uma actividade com um óbvio Futuro, para os vosso filhos, eis mais um Sistema compatível com as peças Lego, e não só acessível, como uma alegria de programar, no fundo juntar outros tantos blocos, como os da Lego, mas lógicos:

Edison offers affordable and Lego-compatible robotics education

Heidi Hoopes

Named to reflect its "inventive spirit," Edison features a host of sensors and runs on open source software. Each small bot is programmable and interacts with the world via IR transmitters and receivers, line tracking, barcode reading, playing sounds and music, and sound detection. One Edison can communicate with another over IR, with the units also able to be programmed to by controlled via TV and DVD remotes.
It’s in Edison’s open source programming tool where the micro action really happens. Edware, similar to Scratch and other graphical drag-and-drop programming languages, allows users to create programs for Edison that users can upload to the bot via their computer’s headphone jack and a cable that ships with the robots. Edware is already available for download for Windows only, though Linux and Mac versions will be provided later.

E o que temos a seguir, é um simpático sistema de Targetas LED, para fácil identificação, nas vossas reuniões de Fabbers e etc. que usa a Técnica do Corte CNC de Acrílico, tudo isto, que podem criar nas Fab-Labs:

LED Nametag 

As a part of the Helle Koepfe-workshop for kids we designed some nametags, such that each kid could make their own led nametag at their short visit of the FabLab Aachen. Therefore ist shouldn't be too complicated, fast to build, not too expensive, and has to be awesome... at least that were the requirements.
Only a 2032 coin cells, two bright 3mm leds and a piece of 2mm acrylic and two short pieces of wire are necessery. The clip-on could be of cource be replaced by a piece of wire, but we had a bunch of them from another project.
The one and only tool which is used is the epilog zing laser cutter of the fablab.
