Cette lentille de contact affiche un écran sur votre œil
On dirait bien qu’ en ce moment , tout le monde travaille sur des lunettes intelligentes . Mais qu’en est-il des lentilles intelligentes ? On dirait bien que les avancées sont assez spectaculaires dans ce domaine ! Des chercheurs de l’Université de Gand ont travaillé sur les lentilles de contact intelligentes.
How to Build a Computer from Scratch, Lesson 2: Choose and Buy Your Parts
Now that you've got a better understanding of what goes into a computer , it's time to actually choose and buy the components you're going to use. In this lesson, we'll show you how to most effectively pick out your parts. Important Considerations for Each Component Even with the above steps, the process is going to feel overwhelming, especially if you don't keep up with all the latest hardware news (as many of us don't).
Back in 2007, a company called D-Wave made waves by claiming it had built a 16-bit quantum computer at a time when most academic labs could only manage a handful of bits. What they demonstrated, however, wasn't a quantum computer in the sense that most people use the term. The company has since started calling its device a " quantum optimizer ."

Par Korben Si vous aimez votre Raspberry Pi, vous avez peut-être décidé de vous lancer dans le développement d'applications pour ce mini ordinateur. Mais avant de faire tourner un programme sur le Pi, il faut d'abord le développer sur son propre ordinateur, mettre les sources sur le Rasberry, puis compiler les sources, puis tester, puis corriger les bugs sur l'ordinateur, puis envoyer à nouveau les sources sur le Raspberry Pi, les recompiler, voir ce que ça donne, recorriger...et ainsi de suite.

Par Korben Si vous êtes un peu court en WiFi chez vous parce que vous habitez une grande maison, je viens de voir qu'il y avait un répéteur WiFi TP-Link TL-WA850RE en promo chez Amazon . Ce petit appareil se branche sur une prise électrique et est conçu pour étendre la couverture réseau et améliorer la force d'un réseau sans fil existant afin d'éliminer les "zones d'ombre". Avec une vitesse sans fil N de 300Mbps, un bouton Range extender (pour se connecter via WPS), une taille minuscule et une conception pour utilisation sur prise murale, étendre un réseau sans fil n'a jamais été aussi facile. De plus sont port Ethernet permet au TL-WA850RE d'agir tel un adaptateur réseau sans fil pour transformer un appareil réseau à connexion filaire en un appareil sans fil.

One of the best ways to take full advantage of your solid state drive (SSD) is to use the performance-maintaining TRIM command. Technology blog GHacks shows us how to make sure TRIM is enabled in Windows 7. While using something like Intel's previously mentioned Toolbox application to TRIM your drive is extremely useful, you need to make sure Windows 7 has enabled it first. And, while Windows is designed to automatically detect most SSDs, sometimes it doesn't work as intended. If you find the performance of your SSD is degrading (or just want to make sure TRIM is properly enabled), run Command Prompt as an administrator and type:

11 Arduino projects that require major hacking skills—or a bit of insanity
Raspberry Pi has received the lion's share of attention devoted to cheap, single-board computers in the past year. But long before the Pi was a gleam in its creators' eyes, there was the Arduino. Unveiled in 2005, Arduino boards don't have the CPU horsepower of a Raspberry Pi. They don't run a full PC operating system either.
Just some cuts and engraves. The rocket model is from elabz . He has some nice models on his website , too. Craft foam - 2mm - black - 75 mm/sec Balsawood - 1 mm - the dark lines were engraved with 50 and afterwards with 10 mm/sec. The outer rings were drawn with 100 mm/sec.

Identifing the parts of old devices is often a pain but I had luck with at least the scanner stepper. For the printer I had found a service manual. But this didn't helped me alot. Scanner / X-Axis The scanner is an old Tevion 2400 dpi scanner. Equivalent to a Microtek Scanmaker 5800. The stepper is a 96 step bipolar stepper motor.

by The Ars Staff There are three ways to obtain a personal computer. You can purchase retail, "mail-order" (when it's sent to yer house), or you can build your own .bonjour, je suis aussi en train de jouer avec la wiimote sur ubuntu et j arrive aussi au meme constat que "wiimote whiteboard" n'est pas très sensible (il consomme aussi pas mal de cpu). Par contre, j'ai essayer la version python "gtk wiimote whiteboard" qui est beaucoup efficace ( http://www.stepd.ca/gtkwhiteboard/ ).

How to Build a Computer from Scratch, Lesson 4: Installing Your Operating System
Now that you've put everything together , you're past all the difficult stages—the rest is a cakewalk. Here's how to install your operating system and get everything up and running. If you've never installed an OS before, it's remarkably easy.Now that you've bought all your components , it's time for the moment of truth: You're ready to actually put together the machine. Assembling your computer can seem daunting, but it's actually pretty easy. Here's what you need to do. Best viewed in 720p. Background music by Tom Woxom .
How to Build a Computer from Scratch, Lesson 3: Building the Computer
The market for cheap single-board computers is becoming one of the most surprisingly competitive spaces in the tech industry. On the heels of the million-selling Raspberry Pi , a variety of companies and small groups started creating their own tiny computers for programmers and hobbyists. Today we have a new entrant that may provide the best bang for the buck for many types of users. It's called the BeagleBone Black and it's the latest in the line of "Beagle" devices that first appeared in 2008, courtesy of Texas Instruments. On sale now for $45 , BeagleBone Black sports a 1GHz Sitara AM335x ARM Cortex-A8 processor from Texas Instruments, up from the 720MHz processor used in the previous $90 BeagleBone released in 2011. ( Edit : While the purchase link is live, the device may not be available until tomorrow morning.
