i would like to have one ;)
pelas mãos da Make, chega ao mercado um peça muito “bonita” que permite expandir para +13 as portas digitais (de saída) da placa de Arduino (LINK)

Miguel o desconfiado
A desfolhar o Público on-line deparei-me com este texto: “O ex-namorado de Filipa clonou-lhe o perfil no Hi5 e humilhou-a na Internet” de Ana Cristina Pereira in Jornal o Público
Fez-me lembrar uma história de um Amigo (Miguel T.) que em conversas e desconversas confessa que não “acredita” na treta do Hi5, nas “cenas das redes sociais” que isso tudo não leva a nada e que o que se passa por lá também pode acontecer num qualquer bar ou discoteca quando “se mete” conversa com alguém que é “mesmo real”.
Num bar ou numa discoteca, nas tais conversas de ocasião onde se trava uma amizade não existe tempo para uma troca de fotografias nem para uma troca de detalhes mais íntimos como a data de nascimento, mas também não existe tempo para que no dia a seguir se possa voltar a contactar para “mais algo”. Eu continuo na minha que as redes sociais vierem para ficar e que aqueles que não as aceitam vão ter mais dificuldades em promover o seu trabalho, as suas ideias os seus saberes.. MAS é certo que esses convívios esporádicos nos bares não levam de certeza a que se faça uso das redes sociais para se tentar denegrir a imagem de alguém assim tão rápido.. não mesmo :)
Cara Filipa, não que isto lhe sirva de lição, não mesmo.. mas que casos destes acontecem em todo o lado.. si é vero.
sugar+arduino
a interactividade nunca mais vai ser a mesma ;) um pequeno tutorial em como utilizar o sugar e o arduino
instalar numa USB pen drive o ubuntu
Bom, estou a instalar no meu EEE o Ubuntu Remix, que é uma derivação do Ubuntu Desktop mas para os novos portáteis notebook, para isso tive que:
_ fazer o donwload da imagem (ISO) do Ubuntu Remix aqui LINK
_fazer o download de uma aplicação de nome unetbootin (unetbootin-windows-408.exe) que se trata de um utilitário e que não é necessário instalar, fiz o donwload aqui LINK
o que é necessário:
_ter uma usb pen com pelo menos 2 gigas livres (este fim de semana vi que as usb pens de 64 megas estão a ficar com preço abaixo dos 40 euros.. oba oba fonte: mediamarket aveiro)
o processo:
_depois de fazer o download deve correr a aplicação (unetbootin-windows-408.exe) de seguida escolher a imagem e a porta da USB pen (a drive no seu computador), fazer clique em OK e esperar um pouco..
depois de instalado (copiado) na pen deve fazer clique em cancelar, retirar a pen e fazer reboot no seu EEE com a pen ligada a ele ;)
Vantagens deste processo:
_não APAGA nada da pen, apenas executa uma cópia de ficheiros para a pen (óbvio se a pen existirem alguns ficheiros com o mesmo nome daqueles que estão a ser copiados a aplicação vai PERGUNTAR se os pode sobrepor==apagar) Atenção: se tiver alguma versão do windows na sua Pen, formate primeiro (ou apague esses ficheiros) para que o resultado final da instalação do Ubuntu tenha sucesso

arduino 2010: “Uno Punto Zero”

Uno Punto Zero
Dear Friends of Arduino
On the first day of 2010 we look back at five amazing years where Arduino has gone from being an idea into our heads to become a widely used platform for hardware learning and experimentation.
We set out to build a platform that helps people get stuff done without having too much focus on the technology used to get it done. We’re pleased to see many people have managed to do just that.
We have faced a happy challenge as the platform has seen more widespread use. We get more and more very qualified contributions and valuable suggestions from a many different sources. It is difficult to satisfy everyone while avoiding the platform bloat that we sought to avoid in our original goals. We believe we have been quite successful at keeping Arduino true to its roots, incorporating suggestions and contributions but still keeping it simple. Arduino has reached a reasonable level of stability and reliability, and it’s time to crystalise the work done so far and to graduate, as the title in Italian says, to 1.0
What does this mean for Arduino?
We plan to stabilise the API and the current IDE so that for the foreseeable future the reference, the examples, the tutorials and the books you buy should stay consistent. This will help people who are teaching, wiriting tutorials and books to stay up to date for longer. We will obviously fix bugs and add new boards to the core as they appear and you should expect everything in 1.0 onward to work properly.
At the same time this allows us to open up other streams for developing “experimental” distributions that are more cutting edge that are more appealing to people with more experience that are willing to trade some stability with more performance and new features.
The schedule for 1.0 release will be as follows: we’ll start a public discussion on the API for 1.0 which will last into February. At that time, we’ll summariseall the suggestions, and incorporate those that we consider coherent with the philosophy of simplicity and ease of use.
In march, during the NYU spring break, we’ll meet up at ITP in New York to exchange notes and test our assumptions followed by a social event somewhere in town (we’ll have more details about this as we are organising it right now)
We should expect to be able to go “Uno punto Zero” by June.
We also recognise that our website has been in need of love for quite a while and we have started working on a new infrastructure where we’ll better integrate its three main elements (Main site, forum and playground) both graphically and technically. A new forum platform is in the works as we try to find a solution that will let us migrate all the immensely valuable content of the current forum without losing a single bit of it.
The main website will become, in the long run, a much more general resource for people learning about Physical Computing and Arduino. There are some amazing tutorials on the playground and around the web, collecting and organising them will provide us with a great resource for learners and we hope to recognize those contributions by including more of them in the main site
Hardware-wise we’re working on some new ideas on how to make Arduino even simpler to use and more affordable. At the same time we’re looking at how, applying the Arduino Philosophy, we can make some other areas of technology more approachable for everybody.
Today everyone of us is working on their new years resolutions, these are ours and we hope you’ll be excited as we are to work on it.

The First 10 Things Everyone Does with their New Arduino
Eis um post de um blog muito interessante sobre as 10 primeiras coisas que se faz quando se compra uma board de arduino :), aqui fica um resumo das dez etapas:
1 – Make it blink
2 – Make it blink faster (or slower)
3 – Make a function to make the Arduino blink
4 – Send stuff over the serial port from the Arduino to your PC
5 – Merge the LED blinking with the Serial
6 – Send something from the computer to the Arduino… and back…
7 – Combine the Serial sending with blinking
8 – Put everything together in one big mega program – count, blink, echo, and blink again
9 – Copy and paste
10 – Meet people on the web who use Arduinos

Uma explicação simples (em formato de video) por parte de Hiroshi Ishii acerca de “tangible user interface”, a representação física, mudar a representação de forma dinâmica..
linguagem processing
Uma frases soltas de uma entrevista aos pais do processing :P
Acerca do inicio da programação: “I was very lucky that my dad brought an Apple II into the house in the 1980s. These early home computers encouraged programming and there were books on programming in Basic written for kids. I don’t remember if I started with Basic or Logo, but I learned a little with both. I hit a wall and I wasn’t motivated to learn more.”
“the big idea of Processing is the tight integration of a programming environment, a programming language, a community-minded and open-source mentality, and a focus on learning — created by artists and designers, for their own community. The focus is on writing software within the context of the visual arts. Many other programming environments embodied some of these aspects, but not all”
acerca do futuro: “We’re only looking as far into the future as 2.0. We’re planning a 1.5 release before that, which will have two additional components. First, the current video system using QuickTime will be replaced by GStreamer. Second, Processing will become more integrated with OpenGL, which will improve the speed of apps that use OpenGL. One of Casey’s former students, Andres Colubri is the protagonist for the GStreamer and OpenGL integration. For 2.0, the text editor (and the development environment, to an extent) will be modernized to include useful features for beginners and experts. At least that’s the plan, it all depends on how much time we have and the contributions of others.
We also want to focus on supporting other projects that extend Processing in different ways. We’d like to spend more time supporting people who are creating Tools and Libraries for Processing, or those who are developing versions that run with other languages (JavaScript, Python, etc.)”

What do you see as the best and worst technology-driven trends emerging in art and design?
By far the best technology-driven trend I am aware of is the free and open-source software and hardware initiatives and the maker communities that have been gaining popularity recently. Technology is a powerful tool for enabling people to enrich their lives, but if the price tag keeps it out of reach of the general public or restrictive rights on ideas and processes exclude others from learning or contributing, the utility and worth of this technology is diminished. The current quality of tools available to the average person are equalling if not surpassing those used by institutions that have influence over many of our day-to-day concerns. There’s enormous power in the ability to re-imagine one’s own environment, and with the advent of open source 3D modeling and geospatial software, it’s possible to redesign one’s own neighborhood and view it in the world theater. In terms of other open hardware and software initiatives, if you don’t have the money to buy a pre- built device? No problem, they provide kits or even schematics so you can build your own from scratch. Want to change something? No problem, they provide all the source code as well so that you can program your own variant of the project. Consumers of these technologies are not merely users of pre-packaged functionality, but are active participants in the development of the products they purchase.
Projects such as Rep-Rap and Makerbot are revolutionizing manufacturing technologies by providing relatively inexpensive 3D printers and CNC machines to the average consumer. Hopefully soon we’ll see average kitchens outfitted with microwave-sized fabbers along side the food processor and toaster that can print you a replacement doorknob or a pint glass from plastic… The Arduino physical computing platform is another notable example of a successful and far-reaching open source initiative. Artists, designers and makers of all types can program a microcontroller to run an interactive art installation, to control responsive architectures or to even sequence the lights in your holiday display. The possibilities are numerous, and if you’re not sure how to do something, there’s a vast user-base who are more than happy to lend a hand. What it all comes down to is the democratization of technology, putting new tools and ideas in the hands of the public, and building a community of people who are willing to learn from and teach others.
As for the worst technological trends, I’m rather concerned by current issues of digital rights management (DRM), net neutrality, file-sharing and unauthorized/unwarranted surveillance, just to name a few. These are certainly interesting and problematic times, and there are no clear-cut answers to these difficult issues. My hope is that the thoughtful and responsible use of technology, including new media artworks that address these concerns can bring awareness of and sensitivity to these issues to the public so that we can make better-informed decisions for our future.
