1000w inverter homemade.wmv. CONSTRUYA SU VIDEOROCKOLA.COM > Como calcular un transformador. El transfomrador componente eléctrico que tiene la capacidad de cambiar el nivel del voltaje y de la corriente, mediante dos bobinas enrolladas alrededor de un núcleo o centro común.
El núcleo está formado por una gran cantidad de chapas o láminas de una aleación de Hierro y Silicio. Ésta aleación reduce las pérdidas por histéresis magnética (capacidad de mantener una señal magnética después de ser retirado un campo magnético) y aumenta la resistividad del Hierro. Funcionamiento de un transformador El cambio de voltaje o corriente que hace un Transformador se sucede gracias a que el devanado secundario es inducido por un campo magnético producido por el devanado primario en conjunto con el núcleo.
El cambio de voltaje o corriente, que entrega el transformador es inverso, es decir que cuando el transformador aumenta el voltaje, la corriente baja; y cuando el voltaje baja, la corriente sube. Construire un transformateur électrique (DIY) Freeside Atlanta makes space for local hackers. Click to enlarge At a regular Tuesday night meeting of Freeside Atlanta, there's talk of building a RepRap machine.
A RepRap, treasurer Raiford Storey explains, is a prototyping device that can make its own parts. Once one's built, it can be used to create another and another and so on. Thousands of machines could be made, replicating one another like a hive of robotic insects gestating inside Freeside's Metropolitan Warehouses space.

TLC "Guides" Why hack a calculator? Why climb Mount Everest? So you're a programmer deciding where to invest your energy.
What's a better idea: the latest Apple device, where hot new games can mean big bucks and millions of users, or a calculator introduced 10 years ago? Most go for iPhones and iPods. But another community thrives in its own way. These are the folks who spend hours trying to elevate their Texas Instruments calculators to a level far surpassing their modest roots. Among their achievements: adding new features, creating new operating systems, connecting the calculator to keyboards and other hardware, playing a video excerpt from "The Matrix," and even running Nintendo Game Boy video games.
Python Interfacing a USB Missile Launcher. I watch Woot on pretty much a daily basis and as a result I frequently end up purchasing toys that I really don't need.
Most recently I picked up this silly pair of USB Missile Launchers for just under 40$ shipped: I finally found some free time yesterday to open up the package and plug them in. The hardware is coupled with a simple GUI controller written in Delphi (MissileLauncher.exe) and a USB Human Interface Device (HID) interface written in C++ (USBHID.dll). Team debuts electronic-hacking how-to videos at HOPE conference. NEW YORK--Want to know how to build your own cell phone charger?
How about putting an old-fashioned pay phone in your home to make voice over Internet calls? A team of do-it-yourself technology gurus are creating a video series that will show you how to hack everyday gadgets to get more--and novel--uses out of them. Limor Fried, who owns the Adafruit Industries electronics building business, and Phillip Torrone, senior editor at Make Magazine, are calling their series "Citizen Engineer.

Introduction DealExtreme propose pour 7,9€, un afficheur à led (rouge, bleu) alimenté par une pile bouton et programmable directement par des boutons situés sur le verso de ce dernier, en plus de tout cela, il est vaguement indiqué qu'il existe une connection USB permettant peut être une programmation depuis un PC.
Il possède 203 leds disposées en 29 colonnes de 7 leds. Quelques semaines après la commande, je reçois cet afficheur, il fonctionne parfaitement bien, malheureusement, le connecteur USB est d'un type inconnu, un démontage s'impose alors pour en savoir plus sur ce dernier, pas de vis, il va falloir employer une manière un peu brutale pour séparer les 2 coques collées.
Une fois ouvert, plusieurs surprises, bonnes et mauvaises : Le connecteur USB ne risque pas de fonctionner, il est connecté nul part (je m'apercevrai plus tard pourquoi) Le tout est piloté par un seul et unique micro-controleur, un Atmel AVR Atmega88, aucun multiplexeur… Un port de programmation est disponible.

Home & Garden: October 2008 : Planet Green. Backyard Graywater System. My garden loves the system, which cost less than $150 in materials, and I’ve already installed pipe and outlets for another one that will reuse the rest of our house’s graywater. Our household of 5 adults does about 6 or 7 loads of laundry per week.
At roughly 40 gallons per, that’s 260 gallons saved. And it’s energy saved as well; around 20% of the energy used in California is related to water use — pumping, treating, disposing, etc. As far as I know, the type of system I built was originally described (although perhaps not designed) by Art Ludwig of Santa Barbara, Calif. He calls this type of system a "branched drain to mini-leach field system" and describes it in detail in his book Create an Oasis with Greywater, which is available at oasisdesign.net.
