firstly, is the wifi shield able to communicate with the Arduino
Yes, but the communication is handled entirely by the Arduino.

scusate una cosa ma AnalogWrite accende anche i pin non pwm basta che duty cycle sia >= 128 giusto??? in pratica x vedere tutto il led acceso basta mattere 128 dovrei distinguere l'accensione dei pin pwm da quelli normali digitali ??? come posso fare ....

Tu peux effacer les deux derniers 00 avec un affichage de type "25  " en rajoutant deux espaces vide derrière le "25". Ce sera mieux que d'utiliser lcd.clear sans arrêt.

Re: Arduino + ENC28J60 + Website - Problemas

Posted: 12 Mar 2013 05:18 AM PDT

Não conheço nenhuma lib para a ENC28J60 que lhe permita funcionar como cliente.
Por isso sugiro-lhe que pense essa situação ao contrário, ou seja, o arduino com a ENC28J60 disponibiliza os dados e o outro computador vai fazendo o polling desses dados.

I am planning to buy the above motor driver to build my first robot. My robot will be very basic, just be able to move with two motors. will that be enough?

Re: Servos fail to move

Posted: 12 Mar 2013 05:14 AM PDT

When I first got my servos, I searched through old wallwarts until I found one that output 6V 500mA which does the job. More current would be nicer if you can find it. Alternatively, four AAs in series will do it if you can figure out a way to connect ...

For example every 40ms the output of every sensor gets printed. How should I alter the code to print the data continuously?
"Every 40 seconds" is NOT "continuously".

soved it, it was an error in the code, i defined a pin as output  that i had used before geting the lcd. after deleting that it works fine now, thanks!

pOLymORpHic hUMansCApE: Art Installation with Raspberry Pi

Posted: 12 Mar 2013 05:01 AM PDT

pOLymORpHic hUMansCApE is an art installation by Nandita Kumar:

Size: 50cm diameter 60cm height
Elements used: Copper, Acrylic, PCB components, Raspberry Pi, Sensor, LCD
Contains 2 videos which are time lapsed and stop motion technique is used.

Documentation by Sophie Winqvist
The art piece has silent Videos but for Documentation music is by Monolake.

The modern city provides both a culturally resonant imagined space and a physical place for the everyday life of its residents. The development of a city plays an important role in the way it stirs and shapes our consciousness. The artist who lives in-between 2 cities: India and New Zealand observes two hugely variant human ecologies.

pOLymORpHic hUMansCApE is an interactive biosphere in a bottle which explores two days in an urban landscape. This installation wishes to evoke discussions on the problems faced by Indian Cities due to urbanization, high population growth and development of slums. The rapid urbanization has spread widely in the last decades, as more and more people are moving to cities in pursuit of better career, social and personal opportunities. At the same time, this massive migration strains the systems that run our cities. Over-crowded transport routes, disappearing spaces, lack of nature, ancient water systems serving a greater population than could have ever been imagined – with city living, all sorts of problems arise that can have a serious impact on our well-being.

Our existing cities should incorporate ideologies target towards sustainable human ecology, which is oriented towards furthering human consciousness. Better cities are about improved human capital, less incidence of disease, more opportunity for leisure and, thus, less stress, making for a more productive, happier workforce in general, which will also contribute to the economy.

Scientists Uncover Invisible Motion in Video

Posted: 12 Mar 2013 05:00 AM PDT

MotionMagnifiedVideo

Welcome to the fascinating world of Eulerian Video Magnification and other motion magnification techniques currently being explored at MIT.

From the NYTimes:

A 30-second video of a newborn baby shows the infant silently snoozing in its crib, his breathing barely perceptible. But when the video is run through an algorithm that can amplify both movement and color, the baby's face blinks crimson with each tiny heartbeat.

The amplification process is called Eulerian Video Magnification, and is the brainchild of a team of scientists at the Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Laboratory.

The team originally developed the program to monitor neonatal babies without making physical contact. But they quickly learned that the algorithm can be applied to other videos to reveal changes imperceptible to the naked eye. Prof. William T. Freeman, a leader on the team, imagines its use in search and rescue, so that rescuers could tell from a distance if someone trapped on a ledge, say, is still breathing.

"Once we amplify these small motions, there's like a whole new world you can look at," he said.

The system works by homing in on specific pixels in a video over the course of time. Frame-by-frame, the program identifies minute changes in color and then amplifies them up to 100 times, turning, say, a subtle shift toward pink to a bright crimson. The scientists who developed it believe it could also have applications in industries like manufacturing and oil exploration. For example, a factory technician could film a machine to check for small movements in bolts that might indicate an impending breakdown. In one video presented by the scientists, a stationary crane sits on a construction site, so still it could be a photograph. But once run through the program, the crane appears to sway precariously in the wind, perhaps tipping workers off to a potential hazard.

It is important to note that the crane does not actually move as much as the video seems to show. It is the process of motion amplification that gives the crane its movement.

Reuters visits the Raspberry Pi factory

Reuters visits the Raspberry Pi factory.

This piece of news footage is all about how the Raspberry Pi you own is made in the UK. It gives you another really close look at some of the processes in the factory – as well as some crystal-clear video of pick and place, you'll see some of the ladies on the line doing hand placement of through-hole parts, and learn a bit more about plans for increasing production (even with a million sold in our first year, sales show no sign of slowing down). The video also discusses our plans to move all of the production (except the red boards for the Chinese market) to the Sony factory in Pencoed, S Wales, where Raspberry Pis are made for us under licence.
