An Online Opensource Robot and Hardware Shop A Trip to Maker Faire Shen Zhen, 2014 The past weekend has witnessed another giant meetup of makers across the globe. At SheKou, a costal area of Shenzhen, the “city of manufacturing”, this two-day event has aroused over 100 dedicated groups of makers to showcase their projects to the coming audience. Being one among them, Team DFRobot take this chance to recall and share what we’ve seen and heard during this trip. Before the Show Thanks to the incorrect weather forecast, we enjoyed a couple of sunny days before Maker Faire Shenzhen, and took visits to some local “spots of interest”. Maker Faire Shenzhen The “Great Show $ Tell” begins with an enormous Bumblebee, standing at the entrance of plaza, fenced off.
"Netduino - Getting Started with *" Series | Coding4Fun Blog The final Hardware Friday post of the year can't just be on one project now can it? Let's get ourselves set for another great year and get set to hit the ground running building some fun Netduino projects with a great set of Getting Started series by Jeroen Swart Netduino - Getting Started with LCD If you want to show more output then blinking LED’s, an LCD module is a good and usually affordable option. They come in different sizes, from 2 numeric-only digits to 40x4 alphanumeric dot-matrix modules. You can also get graphic LCD’s, that range from modules with small resolutions (e.g. 122x32 or 240x128 pixels) to more professional LCD screens (e.g. 5” or 7”), but I will stick with alphanumeric LCD’s for this post. Netduino - Getting Started with steppermotors, shieldless In my previous post, I explained how I used the Adafruit motorshield to control a steppermotor.

Débuter en domotique Situation immobilière, solutions techniques adaptées à vos besoins, budget et compétences utilisateurs sont les éléments qui détermineront les orientations de votre projet domotiques. Il n’existe pas de solution idéale car chaque besoin sera spécifique et différent. Cependant, je vous propose avec cet article de passer quelques obstacles avec un peu de recul sur votre besoin en vous posant quelques questions. le confort (automatisation, personnalisation suivant votre environnement, et intelligence de votre système) ;les économies (connaitre vos consommations pour appliquer un modèle économique adapté) ;la sécurité (alarme incendie, alarme inondation, alarme intrusion, surveillance vidéo …) ;l’aide à l’autonomie (le contrôle distant de votre habitat depuis un terminal informatique). Tout au long de cet article, j’utiliserai trois expressions permettant de définir les trois grandes classes technologiques de la domotique actuelle. 1.1 – Locataire ou propriétaire 1.2 – Type d’habitation
Microsoft, GE Healthcare to form new health IT company, Caradigm The companies completed their joint venture agreement, receiving regulatory approval to form a new company that combines Microsoft's data platforms with GE's clinical applications. The two companies have just received regulatory approval to form a new health IT company that combines Microsoft’s strengths in developing large-scale data platforms with GE Healthcare’s expertise in building healthcare applications. Caradigm (part care, part paradigm) wants to help “health systems and professionals to use real-time, organization-wide intelligence to improve healthcare quality and the patient experience,” they announced in a news release on Wednesday. The joint venture will develop and market an “open healthcare intelligence platform” and “collaborative clinical applications” focused on managing population health. Caradigm is where Microsoft moved almost all of the hundreds people and handful of products that formerly were part of its Health Services Group. Image: Caradigm Jun 7, 2012
Maker Faire New York Debrief - News by Emcee Grady | October 06, 2010 | 8 comments Share Use this URL to share: Share on Twitter Share on Facebook Share on Google+ As you may have known, Maker Faire New York has come and gone and SparkFun was in attendance. It was awesome! One of our favorite things to do at Maker Faire is meet and talk with some of our customers. A pair of happy young soldering gurus! We also ran soldering workshops! Playing the SparkFun "Snake Stomp" game. We hope those who made it out to Maker Faire had as much fun as we did! Cables de RED 100/Gigabit -Tutorial de armado -resubido Titulo : Tutorial de armado cables de redes. Hola taringueros, como siempre dejandoles algo de conocimiento, puede ser que algunos o muchos sepan como armar un cable de red; pero muchos no lo saben y estan en la duda de como armar su propio cable de red. Alicate (preferible de corte recto/puede ser que no sea necesario) Pinza para crimpear cables red/telefonico Cutter (Trincheta en algunos lugares) Tester (Puede ser no necesario) Probador de Lan (Puede ser no necesario) La pinza de crimpear tiene cuchillas para cortar el cable de red y del otro lado cuchilas para pelar el cable en la longitud necesaria. Introducimos el cable un poco y cortamos Ahora podemos comenzar el trabajo prolijo, introducimos ese cable cortado por la parte de las cuchillas de pelado y miramos que el cable haga tope en la cuchilla de corte Presionamos un poco la pinza para hacer solo un corte en la vaina del cable de red, en mi caso solo toco la vaina y la voy girando para que se corte solo la envoltura.
The Internet of Things (and With Things) (By Roberto Saracco, IEEE ComSoc Senior Member, Chair of ComSoc Strategic Planning Committee) It is happening. More and more objects (mostly sensors so far) are connected to the Internet. STEP 1: Why is this happening? Electronics is cheap, and getting cheaper by the day. Electronics and software make objects aware of their environments. Communications is getting more and more pervasive. IEEE Communications Society (ComSoc) is active in all these “enabling” technologies, from radio to networks and protocols. STEP 2: Is it business as usual? Our telecommunications networks were designed for symmetric traffic at 64 kb/s with individual transactions lasting about 3 minutes. And now, it's changing all over again. And ComSoc, again, is on target, looking at the future of the internet, at the future network architectures. STEP 3: Is IoT the next Big Thing? IoT is using limited traffic capacity, and it is not going to generate tremendous revenues to operators in terms of traffic sale.
Liudr's Blog Utilizar el pc como osciloscopio Con este sencillo tutorial construiremos una entrada al ordenador para ser utilizado como osciloscopio. Transformaremos nuestro pc en un osciloscopio. El osciloscopio es quizás el instrumento de medida más deseado por todo aficionado/a a la electrónica. Más deseado, porque es un instrumento caro y no todo aficionado se puede permitir ese gasto. Sin embargo podemos convertir nuestro ordenador en un osciloscopio "casero" con prestaciones aceptables. Lo que vamos a hacer es utilizar la tarjeta de sonido de nuestro ordenador como entrada, y un software especial para mostrar las señales que apliquemos a esa entrada. Vamos por partes; En cuanto al hardware lo que necesitamos es: - 2 metros de cable rojo flexible, - 1 metro de cable negro flexible, - 2 conectores estéreo jack hembra de 6,3mm, - 1 conector macho jack estéreo de 6,3mm, - 2 pinzas de test rojas, - 1 pinza de test negra, - 2 resistencias de 100K ohmios y - 2 trimmers de 20K. El esquema sería este.
CarTel [MIT Cartel] Road transportation is a “grand challenge” societal problem. With close to a billion vehicles on the road today, and a doubling projected over the next 15-20 years, we face pressing challenges to the efficiency and the safety of this infrastructure. The CarTel project combines mobile computing and sensing, wireless networking, and data-intensive algorithms running on servers in the cloud to address these challenges. CarTel is a distributed, mobile sensing and computing system using phones and custom-built on-board telematics devices; one may think of it as a “vehicular cyber-physical system”. CarTel helps applications easily collect, process, deliver, analyze, and visualize data from sensors located on mobile units (mobile phones and in-car embedded devices). VTrack and CTrack are two related systems that process error-prone position streams to accurately estimate trajectories and delays. The results of VTrack/CTrack are accurate delay estimates for road segments. Version 0 Version 2
