David Mellis from the MIT Media Lab has been designing and refining his DIY cellphone, one that you can build yourself from his open source design files and code. A “difficult, but potentially do-able project,” the phone has the basic features that you’d expect: you can make and receive calls and text messages and it has a phone book for storing numbers. To coincide with CES, we got an update from David on his homebrew consumer electronics device.

What was the biggest design challenge?

Balancing the desire to make a functional phone while keeping it as easy as possible to assemble by hand. Mostly, this was a question of sourcing the right components: parts small enough to fit into a reasonable overall size but still big enough to solder manually. For example, I was lucky that the GSM module on the Arduino GSM shield (the Quectel M10) was both fairly small but with reasonably big solder joints — unlike many GSM modules with 0.5mm pitch connectors. Finding a small and robust screen was also a challenge: the LCD I used initially would break after a month or so of use. The LED matrix I’m using now has been fairly stable, but only shows eight characters. Similarly, I managed to find a nice small speaker, but the audio quality isn’t amazing. In general, there’s been a lot of tradeoffs: balancing functionality against ease-of-assembly. This problem is a lot harder when you’re trying to make something that you’re going to carry in your pocket every day.

What’s the next feature or improvement that you would implement?

I’m less interested in adding specific improvements to the phone itself than in exploring other ways to help people make their own devices. For example, I’m working on a GSM module that’s effectively a cellphone and an Arduino in one, so people can build their own cellphone interface or form factor. I’d also like to find ways to make PCB design appealing to new groups of people; making simple boards doesn’t seem that hard, so I’m curious to see how we might be able to place it in a design context rather than an engineering one. Finally, I’m also interested in finding ways to get the phone itself out to more people, whether by having them build it themselves or otherwise distributing it.

David's cellphone module allows people to build their own cellphone interface or form factor.

ex: O grafeno pode fazer quase tudo

Visível a olho humano em uma camada de apenas um átomo de espessura, capaz de dobrar-se em formas que fariam a minha mãe corar (e olha que isso não é pouca coisa) e muito provavelmente o material mais forte do mundo: o grafeno é, sem dúvida, um valentão de primeira.

Na verdade, ele mostra suas propriedades incríveis em quase todos os campos de força e condutividade. Ele transporta os elétrons 10 vezes mais rápido do que o silício e em breve poderá substituí-lo como material principal para transistores e peças de computador. Se isso não é impressionante o suficiente para você, que tal o fato de que o grafeno é tecnicamente um plástico, por isso não deveria ter nenhum papel em conduzir eletricidade – no entanto, ele desempenha esse papel melhor do que ninguém?

Abstract

The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes. The acoustic axis of the ultrasound beam in conventional studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers. In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and moved three- dimensionally by localised ultrasonic standing waves, which were generated by ultrasonic phased arrays. Our manipulation system has two original features. One is the direction of the ultrasound beam, which is arbitrary because the force acting toward its centre is also utilised. The other is the manipulation principle by which a localised standing wave is generated at an arbitrary position and moved three-dimensionally by opposed and ultrasonic phased arrays. We experimentally confirmed that expanded-polystyrene particles of 0.6 mm and 2 mm in diameter could be manipulated by our proposed method.

project veasyble

 

http://www.veasyble.com/projecteng.html

 

What: VEASYBLE is a set of wearable accessories that can be converted at a touch into a means of isolation.
Composition: VEASYBLE is made of paper bonded to polyethylene and fabric.
Objects: visor, ruff, bag, mask.
Keywords: Isolation, Ornament, Revelation, Intimacy.

The project is based on three keywords: isolation, intimacy and ornament. It consists of a set of wearable objects that can be converted into means of isolation, to create a personal intimacy in any environment. The idea derives from a reflection on the change in our relationship with the domestic environment, due to the effects of our increasing mobility, and how this has affected our concept of intimacy, creating new demands. This led to the design of four accessories, screen for four different parts of the body: eyes, ears, face and upper body, expressing, through their shape and colour, our desire for intimacy at any time, any place, on various levels.

An ornament that can be worn.
A gesture to transform it.
A secret place for personal intimacy.
A reminder of our exterior aspect.

Extraordinary and historic debate on human nature in English plus sub-titles in English for parts in French and Dutch..

Dutch philosopher Fons Elders invited two of the world’s leading thinkers — the American linguist and activist Noam Chomsky and the French social theorist Michel Foucault — to debate a thorny and perennial question: is there such a thing as an “innate” human nature, and if so, what are its implications for our ideas about power, justice, revolution, and the shape of the ideal human society?

Dutch Design Week 2013: Portuguese designer Susana Soares has developed a device for detecting cancer and other serious diseases using trained bees ( + slideshow).

The bees are placed in a glass chamber into which the patient exhales; the bees fly into a smaller secondary chamber if they detect cancer.

“Trained bees only rush into the smaller chamber if they can detect the odour on the patient’s breath that they have been trained to target,” explained Soares, who presented her Bee’s project at Dutch Design Week in Eindhoven last month.

Scientists have found that honey bees – Apis mellifera – have an extraordinary sense of smell that is more acute than that of a sniffer dog and can detect airborne molecules in the parts-per-trillion range.

Bees can be trained to detect specific chemical odours, including the biomarkers associated with diseases such as tuberculosis, lung, skin and pancreatic cancer.

Bees have also been trained to detect explosives and a company calledInsectinel is training “sniffer bees” to work in counter-terrorist operations.

Los caminos del arte son desconocidos, a veces inescrutables, así le ocurrió a esta joven artista quien abandonó la abogacía por sus, hasta entonces, pasatiempos: la pintura y el dibujo. Su interés por el arte contemporáneo se intensificó hasta que decidió abandonar las leyes para convertirse en artista; de la carrera de Derecho aprendió las habilidades de gestión e investigación, las que más tarde le ayudarían a legitimar su producción artística y fundamentar su obra para el escrutinio público.

What is Botanicus Interacticus?

http://www.ivanpoupyrev.com/projects/botanicus.php

We envision a future where interactive devices are not manufactured but are living, growing organisms. Botanicus Interacticus is an exploration into the design of highly expressive interactive plants, both living and artificial. It has a number of unique properties. The instrumentation of living plants is simple, non-invasive, and does not damage the plants. Using our Touché technology, only a single wire has to be placed anywhere in the plant’s soil.

Botanicus Interacticus allows for rich and expressive interaction with plants. Depending on the physiology of each plant species, Botanicus Interacticus can allow a broad variety of gestures such as sliding fingers on the plant stem, detecting touch and grasp location, tracking proximity between the user and plant, and estimating the amount of touch contact.

With Botanicus Interacticus technology any living plant can be turned into a musical instrument, a game controller, a light switch, an elevator button, or a motion detector. Interactivity and responsiveness can be added to homes, streets, and even entire cities, unobtrusively and sustainably simply by growing plants.
