gribouillis de lumière Le 12 avril, les scientifiques en herbe de l’atelier du mercredi à l’Atlas ont réalisé de superbes peintures graffitis gribouillis lumineux. Cette technique originale, aussi appelée "light painting" ou "light graff", essayée avec plus ou moins de succès par de nombreux artistes allant de Picasso à Marko est à la mode puisqu’elle a été utilisée pour l’affiche du festival de Cannes 2010 (ce que nous ne savions pas quand nous avons prévu cet atelier ! ) Cette activité, à la frontière entre création artistique et technologie, a permis à nos petits passionnés de sciences de s’amuser à dessiner dans l’espace mais aussi de comprendre le principe de la photographie, le rôle de la lumière et du temps de pose.

The Toaster Project I'm Thomas Thwaites and I'm trying to build a toaster, from scratch - beginning by mining the raw materials and ending with a product that Argos sells for only £3.99. A toaster. After some research I have determined that I will need the following materials to make a toaster. Copper, to make the pins of the electric plug, the cord, and internal wires. Iron to make the steel grilling apparatus, and the spring to pop up the toast. Nickel to make the heating element. Part of the project consists of finding the places where it's possible to dig up these raw materials. Finding ways to process the raw materials on a domestic scale is also an issue. Microwaves, as we all know, are just so much more convenient - and so I tried to replicate the industrial process outlined in the patent using a domestic microwave. The practical aspects of the project are rather a lot of fun. So are toasters ridiculous?
WifiTagger The Basics: 1) Get a TP-Link WR741ND router (around $10-20) 2) Download the wifitagger firmware 3) follow the README 4) drop modem in public 5) connect to “Free Public WifiTagger”, instant unlimited tagging of networks within range, 100% satisfaction guaranteed!! WifiTagger is a router which is enabled to tag wifi networks. Too lazy to make one? Links Switchers A switching power supply is a device transforming the voltage from one level to another. Typically it is taken from the mains and transformed to the DC levels that logic requires in a PC or a battery loader. The main differences between the linear and switched-mode regulator are in the size, weight and efficiency. Since a switched-mode converter can operate at significantly high frequencies, then a smaller transformer using ferrite cores can be used. Articles and resources
The Lightgraff collective Continuum Fashion : N12 bikini The N12 bikini is the world's first ready-to-wear, completely 3D-printed article of clothing. All of the pieces, closures included, are made directly by 3D printing and snap together without any sewing. N12 represents the beginning of what is possible for the near future. N12 is named for the material it's made out of: Nylon 12. This solid nylon is created by the SLS 3D printing process. Shapeways calls this material "white, strong, and flexible", because its strength allows it to bend without breaking when printed very thin. The bikini's design fundamentally reflects the beautiful intricacy possible with 3D printing, as well as the technical challenges of creating a flexible surface out of the solid nylon. N12 is significant in being a ready-to-wear design.
PirateBox DIY by David Darts PirateBox 1.0 has been released and building or upgrading a PirateBox has never been easier! Please refer to this tutorial for instructions and more info. For support, be sure to visit the new PirateBox Forum. PirateBox can be configured to run on many devices, including wireless routers, single-board computers, laptops, and mobile phones. OpenWrt PirateBox will potentially run on most OpenWrt compatible routers with USB storage. OpenWrt with Mesh Thanks to lead PirateBox developer Matthias Strubel PirateBox can now be configured to create wireless mesh networks using Alexandre Dulaunoy’s Forban. Raspberry Pi PirateBox can be configured to run on single-board computers like the Raspberry Pi. PirateBox Live Check out Cale Black’s Linux PirateBoxLive and Windows PirateBoxLive for tutorials outlining how to run PirateBox directly from a USB flash drive. Android PirateBox can also be run on Android.
OpenPICC RFID Emulator and Sniffer Project - OpenPCD From OpenPCD OpenPICC 1 board Breaking into a Mifare Classic protected key vault that uses only anti collision as a security feature - no cryptography is used by that vault. Introduction This device is obsolete - please use OpenPICC SnifferOnly 13.56MHz instead for sniffing The OpenPICC project for Proximity Integrated Circuit Cards (PICC) is the counterpart to OpenPCD.

Intéressant de voir l’utilisation qu’il fait de la technique du light painting… brianmatthewhart / via Cubify launches 3D printed shoes you can print overnight News: designer Janne Kyttanen has created a range of 3D-printed shoes for women that can be made at home overnight to be worn the next day. Kyttanen, creative director at printing giant 3D Systems, has created four different styles of wedge shoes that can be made using 3D Systems' CubeX printer. Consumers can download the free digital files for the shoes, select the size they require and print them in a colour of their choice. The project is intended to attract new audiences to 3D printing, which has tended to be dominated by products aimed at men. "I don't know what it is with women and shoes, but I like it," said Kyttanen, in a press release straight out of Mad Men. Each shoe takes upwards of six or seven hours to print, meaning a pair could be produced overnight, assuming two shoes could be printed simultaneously on one printer. "Janne is taking the convenience of online shopping to a whole new level," says 3D Systems. Kyttanen is also working on 3D printed food.
Pachube [WebApp, iPhone, Android] - Discover and share realtime data from objects, devices & buildings around the world Pachube is a web service that enables you to store, share & discover realtime sensor, energy and environment data from objects, devices & buildings around the world. Founded by Usman Haque, architect and director at Haque Design + Research, Pachube is a culmination of 12 years of ongoing work. In a nutshell, Pachube is a little like YouTube, except that, rather than sharing videos, Pachube enables people to monitor and share real time environmental data from sensors or devices that are connected to the Internet. These do not only have to be environmental but also personal, such as weight, mood and many more ideas on how to use Pachube available here. Pachube makes it as simple as possible to build applications, products and services that bridge physical and virtual worlds. Pachube adds value to physical interconnectivity: it’s not just about datastreams, but about the environments that make up the datastreams. Useful links: This is a video of Morgellon‘s first Pachube project.
HID iClass demystified - OpenPCD From OpenPCD HID iCLASS On-Air-Protocol for mutual authentication HID Access Control Application read with a standard OMNIKEY 5321 RFID reader - shown both in encrypted and decrypted form As rumors are flying high, we would like to make some clarifications concerning the key vulnerabilities we found. The most important finding of our research is that HID iCLASS Standard Security cards can be easily read and copied with low cost consumer USB RFID readers due to the fact that the same two keys were used world-wide for all HID iCLASS Standard Security installations. An in-depth description of our security analysis can be found in our white paper Heart of Darkness - exploring the uncharted backwaters of HID iCLASS security. Meet us on recon.cx in Montreal on July 14-16, 2012 Meet Milosch and Brita of the OpenPCD hardware team on recon.cx in Montreal, Canada!

Nendo adapts Japanese paper-making to make Semi-Wrinkle Washi lamps Japanese designers Nendo have adapted a traditional Japanese paper-making technique to create a series of lamps that are smooth at one end and gently wrinkled at the other. Nendo called the collection Semi-Wrinkle Washi, with "washi" being the name for Japanese paper made from plant fibres. "Washi is made by passing fine screens through a bath of plant pulp and water to collect the pulp, then by drying the screens and peeling off the new paper sheets," said the designers. To create the lamps they collaborated with Taniguchi Aoya Washi, a company in the Tottori Prefecture in western Japan which is famous for creating three-dimensional objects using the same technique. According to the studio, the lamp shades created through this process are so smooth that they "can be confused with white glass or plastic." "After running into this problem, we decided to take the best of both worlds: to create lighting fixtures that are only half-formed with the wrinkle process," they explained.
