L’atelier Hypermedia enseigne la conception d’images, de programmes et d’animations informatiques. l’accènt est mis sur la construction de dispositifs singuliers et experimentaux, plutôt que sur la maîtrise de logiciels ou de procédés standardisés : les étudiants sont invités à construire leur propres outils, par le biais de langages simples ou complexes tels que BASIC, Logo, Robolab, Lego Mindstorms, C, Lingo, Cocoa, Javascript, Actionscript, Processing, MySQL/PHP, ou Java. L’atelier Hypermedia ne voit pas de contradiction dans l’idée d’un travail plastique de la programmation. L’atelier ne fait pas de distinction entre low-tech et high-tech. les supports de création peuvent aller de Macintosh à Windows, en passant par Gameboy, Atari, Palm, PocketPC, Apple ][ ... L’atelier s’oppose à toute notion de sous-traitance, et préfére travailler avec les autres ateliers dans une logique d’interfaçage.

The processing code for time lapse captures through the iSight camera with a static centered slit looks like this:

Slitscan imaging techniques are used to create static images of time-based phenomena. In traditional film photography, slit scan images are created by exposing film as it slides past a slit-shaped aperture. In the digital realm, thin slices are extracted from a sequence of video frames, and concatenated into a new image.

Snowball is a small string processing language designed for creating stemming algorithms for use in Information Retrieval. This site describes Snowball, and presents several useful stemmers which have been implemented using it.

Do you want to test your next Mac OS X-to-Arduino project without always having the Arduino available? Do you want to test you cool Processing application when your mate hasn't finished writing the Arduino sketch? Do you want to do test driven development of your Mac OS X based application without dependency on your microcontroller? If the answer to any of these questions is yes, then VirtualSerialPortApp is for you!

Shoebot is a pure Python graphics robot: It takes a Python script as input, which describes a drawing process, and outputs a graphic in a common open standard format (SVG, PDF, PostScript, or PNG). It has a simple text editor GUI, and scripts can describe their own GUIs for controlling variables interactively. Being pure Python, it can also be used as a Python module, a plugin for Python-scriptable tools such as Inkscape, and run from the command line. It was directly inspired by DrawBot and Shoes. Thus, "Shoebot."

Processing for the Web is a proposed Mozilla-sponsored initiative to create a complete and robust port of the Java-based Processing language and environment (popular for art, design, and visualization applications) to the open web, using standard technologies such as JavaScript, Canvas, etc.

We often think of scientific ideas, such as Darwin's theory of evolution, as fixed notions that are accepted as finished. In fact, Darwin's On the Origin of Species evolved over the course of several editions he wrote, edited, and updated during his lifetime. The first English edition was approximately 150,000 words and the sixth is a much larger 190,000 words. In the changes are refinements and shifts in ideas — whether increasing the weight of a statement, adding details, or even a change in the idea itself.

OpenProcessing is an online community platform devoted to sharing and discussing Processing sketches in a collaborative, open-source environment.

This is an overview of the hardware/software/services I used:

Sensor > Arduino > Processing > PHP > Twitter

A LDR (light dependent resistor) is glued on the on/off led of the coffeemachine. When the coffeemachine is switched on the led turns on, the ldr detects this light. This LDR is connected to an Arduino microcontroller, Processing reads the value from the Arduino using Firmata and Processing sends this to a php file which will send it to Twitter.

(But that seems unlikely to happen unless someone familiar with HTML5 writes it, because anyone else would find it very hard to understand the HTML5 processing model in enough detail without spending ages learning it)

some visualisations for wiki data. My goal was to deliver some amazing visuals which could be applied to any data set. I wanted to explore the potential of two great new graphics libraries for JavaScript: Processing.js and Raphael.

Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to take the step from physical prototyping to actual product. We are creating this software in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCB layout for manufacturing.

This tutorial introduces a Processing interface sketch provides a GUI for the command-line interface written into the Arduino RFID example. You should read that tutorial first. The sketch shown here also allows you to upload tags it reads to O’Reilly’s Emerging Technology Conference attendee portal, and retrieves the resulting profile. The API for this was written by Edd Dumbill. The Processing sketch retrieves RFID tags from the Arduino reader serially, then passes the tag via a HTTP request to a PHP script on a remote server, shown below, that adds an authorized login to the O’Reilly site.

This tutorial shows how to make an Arduino-based RFID reader that reads Mifare tags and stores them in EEPROM. It is a modification of Alex Zivanovic’s code on Tinker.it. Thanks to Alex and Massimo Banzi for the reference. Once you’ve got it running, go on to the RFID to Web example, which provides a Processing interface sketch provides a GUI for the command-line interface written into the Arduino code.

Mifare RFID tags, like other RFID tags, contain a serial number that can be read using an RFID reader, but they also have a limited amount of memory space that you can write data to, and read back from. This can be handy if you want to do something like keep a user’s account balance or name directly on the RFID tag.

This tutorial explains how to read from Mifare RFID tags from your computer using a Sonmicro SM130 read/write module. The sketch below is written in Processing using my SonmicroReader library. The SM130 has a TTL serial interface that you can connect to a micocontroller, or to a personal computer through a USB-to-serial interface. Using the latter, it’s pretty simple to send serial commands to it and receive the data back. The entire Processing sketch can be downloaded here: rfid_simple_0001.
