#TEST : Le Nabaztag:Tag n’est pas mort ! Faites parler votre installation domotique à moindre coût! Salut à tous! Il y a quelques temps j’ai fait l’acquisition d’un Nabaztag:Tag d’occasion, vous savez, l’ancienne version de l’actuel Karotz, ce petit lapin connecté capable de communiquer avec vous ! Le but était de pouvoir faire communiquer mon installation domotique avec les personnes (et animaux ) vivant dans ma maison. Par exemple, rappeler qu’une fenêtre est ouverte depuis trop longtemps si la température extérieure est faible, annonce des heures creuses … Bref Si je n’ai pas choisi le Karotz, et bien, c’est tout simplement à cause du prix! Voici une petite photo du joujou accompagné de ses Flatnanoz : Pour ceux qui ne connaissent pas, ces petits portes clef (flatnanoz) servent à déclencher des actions lorsqu’on les passe devant le lapin (ex: annoncer la météo, appeler une Url..). Une fois votre lapin fraichement déballé du carton et branché, vous allez devoir le synchroniser avec un serveur afin de vous en servir. Les plus connus sont : Exemple de services proposés par Nabalive :

WikiCitoyen | Hardware / Gasser Gasser is a self-contained mobile sensor for sensing NO2, O3, and SO2. Currently we run it only with NO2 as that is the most present pollutant in Paris. Gasser has essentially three main parts: The sensor (any analog or digital sensor can work) -- top left in the main box. After testing an ensemble of various sensors and holding many long-winded discussions with experts in the field, we have currently settled with the Alphasense B4 series of sensors. Output of the sensor is in the sub-mV range, and therefore proper grounding and filtering of the lines to and from the sensor is essential. We currently use a Raspberry Pi with a Delta-Sigma ADC. We quickly fell in love with the Huawei E220 GPRS dongle, it has proven to be extremely stable, cheap, and have rather good reception. We currently use an 8Ah battery often billed as something to "recharge your iPad and iPhone" with.
PCIDatabase.com - Repair Tool of the Week After you do a clean install of Windows, you go to the Device Manager and discover the dreaded question mark next to an “Unknown Device”. You could just download the driver for this device, but you don’t know what it is! This is where PCIDatabase.com comes in handy. To find out what a PCI Device is, go to Device Manager, right click on the Unknown Device and choose Properties. You will want to get the ID starting with VEN_ and the ID starting with DEV_. For this example I am just going to use the Device ID and go to PCIDatabase.com. If it knows the device, it’ll come up with something like this: Keep in mind, this site is based off user submitted data so there are no guarantees about its accuracy.Site: Thanks to forum member rusty.nells for recommending this.

IoE is changing our world, but its effect on daily life will be most profound. How will the IoE happen? As a leader, Qualcomm has an unmatched portfolio of visionary solutions that deliver the connectivity and communication needed to support the IoE opportunity industry-wide. AllJoyn™ is the universal open software connectivity and services framework that enables smart things to seamlessly connect across brands and operating systems. Qualcomm solutions deliver at the scale of global enterprise, with cellular and connectivity technologies that transform the way business is done and customers are served. Qualcomm AllPlay™, built on AllJoyn, brings the freedom of wireless audio to everyone.
index The idea I wanted to control and monitor parts of my house. So I thought about building a device that would: Control my Insteon devices Monitor some relay triggers (alarm system PGM, my sump pump, doors) generate wakeup calls control IR cameras generate sounds (alarms, welcome message, ...) I decided to get a Raspberry PI and make an expansion board to do all this. Raspberry PI preparation This is what needs to be done on the raspberry pi: Prepare a Linux image Allow ssh root login and configure network Enable sound card and install alsa-lib Enable serial port Configure a syslog server Configure timezone (make symbolic link /etc/localtime -> /usr/share/zoneinfo/Canada/Eastern) Install berkeley DB (5.3.21) Auto-start server in /etc/rc.local Install bind (DNS server) For this project I decided to use ArchLinux on the rPI. To enable sounds, I had to create the file /etc/modules-load.d/sound.conf and add a line that states: snd-bcm2835. CC=arm-unknown-linux-gnueabi-gcc . Development Chassis

Piloter des dispositifs sans fil Électronique | Informatique Niveau: Avancé Jonathan Schemoul Montage avec la Leonardo Partie 1: Réception en 433 MHz Vous avez sans doute entendu parler ou vu des détecteurs de fumée, d'ouverture de porte, des télécommandes, des prises murales, etc. sans fil ? Que ce soit les modèles chers que vous trouvez en magasin ou les modèles chinois bon marché, la plupart, s'ils ne sont pas avancés, utilisent la bande de fréquence 433 MHz (n'essayez pas ceux en 315, ils sont illégaux en France). En ce qui concerne ces capteurs en 433 MHz, il se trouve qu'ils utilisent pour la plupart un protocole très simple, introduit par des circuits intégrés chinois à bas coût, les PT2262 côté émission et les PT2272 côté réception (d'autres plus exotiques comme les SC5262 / SC5272, HX2262 / HX2272, EV1527, RT1527, FP1527 ou encore HS1527 peuvent être trouvés et fonctionneront aussi).

Don’t Waste eWaste: UnMaking a Canon Printer/Scanner/Fax into Parts Make: Projects Don’t Waste eWaste: UnMaking a Canon Printer/Scanner/Fax into Parts Before you make something it is helpful to unmake something. By David Nutty Category: Hacks, Home Time Required: 30 - 60 minutesDifficulty: Easy View Comments Share this: Email This guide will unmake a Canon printer/scanner/fax into Maker resources. So let’s disassemble someone else’s product. Tools Tools Print Project Steps Step #1: Break it Down! PrevNext This is a multi-function machine so we will have a printer, a scanner (copier & fax), and miscellaneous paper trays and feeds. Step #2: Paper Tray: Remove It! Let's start by removing the top lid of this puppy. Step #3: Paper Tray: Remove flaps & screws. Investigate the paper tray for any obvious screws, etc. to take off. Step #4: Paper Tray: Feed Rollers! Okay ... so we removed the screws and got this neat paper feed mechanism out. Step #5: Paper Tray: Flip over and remove screws. Nothing major here - easily-visible screws to remove.

Qualcomm IPQ : les puces mobiles mènent à tout, même aux réseaux intelligents Le groupe Qualcomm conçoit des plates-formes mobiles pour smartphones et processeurs et domine largement le secteur avec sa famille SnapDragon mais son activité le conduit à explorer également des domaines annexes de la connectivité sans fil et des problématiques de réseau. Ayant racheté le spécialiste des composants WiFi Atheros (devenu Qualcomm Atheros), le groupe a acquis une expertise dans les composants sans fil mobiles mais aussi dans les questions plus générales de WiFi domestique et de gestion des flux dont il tente maintenant de trouver des débouchés. La plate-forme Smarthome voulue par Qualcomm repose sur une unité comprenant un processeur d'application dual core 1,3 GHz sous micro-architecture Krait (utilisée dans les familles SnapDragon) associé à un puce dual core 730 MHz Qualcomm Atheros de gestion de flux et pouvant agréger jusqu'à 5 Gbps de bande passante en combinant 4G LTE, WiFi 802.11ac, HomePlug, Ethernet...
Yoctopuce The Embedded Beat: Maker movement will fuel the innovations needed for IoT edge nodes Earlier this year, Tom Simonite published an article in MIT Technology Review titled “Wanted for the Internet of Things: Ant-Sized Computers” that included a review of our Kinetis KL02 chip. The article highlights its size: 1.9mm2 X 2mm2, which makes the KL02 is the smallest 32-bit MCU in the world. And thanks to ARM’s powerful M0+ core, it brings robust real-time embedded processing capabilities to enable what Dr. Prabal Dutta of the University of Michigan calls “smart dust.” After the article was published, I was bombarded with emails from a variety of individuals and what seemed to be very small start ups (lots of gmail addresses!). Thanks to ARM, one can now get access to the latest MCUs from their licensees such as Freescale, and all the tools you need to program the device, along with the development boards in form factors such as Freescale’s Freedom development platform or Arduino boards for less than $15 USD.
