Scratch Blocks

A Google e a malta do Media Lab vão refinar uma nova aplicação, ao que parece a parceria foi estabelecida recentemente o que vai possibilitar o desenvolvimento de uma nova aplicação, de nome “Scratch Blocks” onde se vai unir a simplicidade/desenho criativo do Scratch (pelo MIT  Lab) com o Blockly da Google.

Esta nova ferramenta, OPEN SOURCE, vai permitir trabalhar com linhas de texto ou com blocos e de ser user friendly para dispositivos com ecrãs pequenos.

Obviamente que uma das grandes vantagens desta parceria é o de terminar com o uso do Flash que o actual Scratch “exige”. (a imagem acima ilustra a ligação do Scratch Blocks com o Lego Wedo 2.0)

Para já o Scratch Blocks tem apenas tem uma versão para developers :P

Scratch Cookbook, o livro

Scratch Cookbook | Packt Publishing

Um destes dias fui convidado para colaborar com um projecto.. e aceitei. :) E deram-me uma prenda que foi o resultado desse projecto, um livro.

O livro, Scratch Cookbook, apresenta um conjunto de situações relacionadas com o uso do Scratch, desde o nível inicial até a um nível médio/avançado onde se inclui um capitulo com o uso de um hardware extra, a picoboard e todos os seus sensores :)

O livro está dividido em 9 capítulos. Os 4 primeiros capítulos apresentam actividades que ajudam no primeiro contacto com o Scratch, mas os restantes, já dão mais algum BOM trabalho! Todos os capítulos são “tutorias”, isto é, acompanhados de explicações, progressivos e com imagens a ilustrar as situações descritas.

Todo o livro tem por base a utilização do Scratch 1.4 (que é a versão que prefiro), mas existe um capitulo no final que apresenta a comunidade, nomeadamente a plataforma onde está instalada/disponível a versão 2.0

Sem duvida um livro a usar e a ter como referência! E obrigado pelo convite :) Que venham mais..

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

Taking an Open-Source Approach to Hardware

Soberbo artigo no the wall street journal :) LINK

The palm-sized Arduino serves as an electronic brain running everything from high schoolers’ robots to high-end art installations. But perhaps the oddest thing about the device is the business model behind it.

InstructablesA wall clock that runs on Arduino hardware.

ARDUINO

Plans for the Arduino, a simple microcontroller board, are available online, and anybody may legally use them to build and sell knockoffs.

The Arduino represents an early entrant in the emerging open-source hardware movement, which like Linux and other open-source software projects is driven by the belief that allowing duplication is a better way to spur innovation than keeping designs under lock and key. Its success suggests that the open-source model could provide a new way for manufacturers to develop and improve upon products.

The main producer of the Arduino is Smart Projects Snc, based in the tiny town of Scarmagno, Italy. This year, the two-person firm is on track to sell at least 60,000 of the microcontrollers, which retail for at least $30 a piece, up from 34,000 last year. Owner Gianluca Martino, an electrical engineer, has had to contract out much of the production to keep up with growth.

It’s a peculiar predicament, since the Arduino’s designs are on the Internet for anyone to download and use.While there are clones on the market, the microcontrollers that Mr. Martino produces, with the map of Italy printed on the back of it, are by far the most popular.

ARDUINO2

“What’s interesting in this kind of open-source project is the feeling of confidence the consumer has,” he says, since people can look up the designs and tailor the Arduino to their needs.

Microcontrollers are ubiquitous in everyday life. They are used as tiny, onboard computers that do everything from tell when a washing machine is out of balance to deploy car airbags in a collision.

The Arduino got its start at the Interaction Design Institute in the city of Ivrea, Italy, in 2005. Professor Massimo Banzi was looking for a way to make it easier for the design students there to work with technology. He discussed his problem with David Cuartielles, an engineer visiting from Malmö University in Sweden, and they decided to make a microcontroller that designers could incorporate into their work.

Engineers use programmable microcontrollers for prototyping new products, but the two professors viewed these as too difficult to work with, and too expensive, for their design students.

They enlisted two students with backgrounds in computer programming to write software for the device and asked Mr. Martino to build the first 200 microcontrollers. They named it Arduino—after a local bar. Knowing that the Interaction Design Institute would close down the following year, they made it open source.

“We wanted to make sure that whatever work we did on the project would survive the fate of the school,” explains Mr. Banzi.

Open-source software, which can be freely downloaded, used or modified by anyone, has been around since the 1980s. It gathered momentum with the advent of the Internet in the 1990s, which allowed open-source programmers to easily collaborate on projects such as Linux or the Apache server software that runs many Web sites.

Open-source hardware applies the same idea to physical things. There are a number of recent open-source hardware initiatives, including the Chumby, a clock-radio sized device that runs software “widgets” to display the weather or stream music, and Bug, a system of snap-together modules that can be used to make a variety of computing devices.

So far, the Arduino has been the most successful. In the space of an hour, a layman can make it blink an LED, run a motor or send a temperature reading to a computer monitor. With a little practice, people have been able to do much more.

Using Arduino hardware, tinkerers have recently created everything from a word clock to a radio-controlled lawnmower for a contest hosted by the Web site Instructables.com.

In addition to the microcontrollers produced by Mr. Martino’s firm, there are a handful of other Arduino makers that pay royalties in order to carry the Arduino name. The development team pumps most of that cash back into the project, splitting what remains at the end of year as partial compensation for the time they spend on it. (“It’s like a Christmas present,” says Mr. Banzi.)

Leah Buechley, a professor at the Massachusetts Institute of Technology, developed a stripped-down, washable version of the Arduino called the LilyPad that can be sewn into fabric to create clothing with flashing LEDs and other effects. Manufactured by Boulder-based electronics retailer SparkFun Inc., about 4,000 of the $21 LilyPads have sold since 2007. SparkFun also sells components, such as conductive thread, to go with it.

Because it’s built on the Arduino’s design, the LilyPad must also be open source. That means that anybody could knock it off, but Ms. Buechley says a clone could never compete. “I don’t really care if someone can copy this thing, because a month from now I’m going to be making something different,” she says. “It’s going to be archaic by the time they catch up.”
