In a previous article we have introduced cheap and easy to make PVC wind turbine blades. Here you will learn how to obtain magnets for free and put them to good use in a wind turbine generator. Hard Disk Drive Magnets 50% of the world's neodymium magnets are currently used in computer hard disk drives (HDD) with each HDD typically containing two magnets. Extracting the magnets from an old hard drive is very easy - usually just a small selection of screwdrivers is required. This can be difficult - the easiest way is to put one corner of the backing plate into a bench vice and bend the other corner of the plate using a pair of vice grips. Neodmium Magnets in Hard Disk Drives The magnets used in hard disk drives are very strong neodymium (rare earth) magnets. Comment on this Article wind

antenna basics Antennas, to quote a friend, are one of life's eternal mysteries. "All I'm totally certain of is that any antenna is better than no antenna and the antenna should preferably erected as high and be as long as is possible or desirable". Here we will discuss the very basics of antennas including the the amazing terminated tilted folded dipole antenna. LAST MODIFIED: Sunday, 23-Jun-2013 12:55:29 PDT Please don't forget to bookmark this valuable electronics tutorial site! Authored by Ian C. Find us on Google+ What are the basics of antennas? Antennas, to quote a friend, are one of life's eternal mysteries. The basic antenna The most basic antenna is called "a quarter wave vertical", it is a quarter wavelength long and is a vertical radiator. This type of antenna relies upon an "artificial ground" of either drooping radials or a car body to act as ground. Antenna Polarisation Depending upon how the antenna is orientated physically determines it's polarisation. Antenna Impedance The Yagi antenna
15 Ways To Create Website Screenshots Taking screenshots of web sites is probably one of the most commonly done tasks on the internet - doubly so if you have a blog or work as a journalist. This week, we wrote about Thumbalizr, a service that lets you take screenshots of websites. However, there are several other tools for easy screenshot capturing - some standalone and some in the form of a browser plugin. Plugins Save as image - an aptly named Firefox plugin that lets you save a page, frame, or part of either as an image directly from Firefox.

Picnik for Firefox - if you use online image editor Picnik this Firefox plugin enables you to easily import a screenshot of the currently opened webpage into it. Snissa - simple Firefox plugin for taking web page screenshots. Screengrab! Standalone programs Paparazzi! Web based
C++ Reverse Disassembly Technical Detail This article's aim is to provide material for modern day decompiling of applications written in C++. We assume you have a solid understand of C++, X86 Assembly, and windows. Overview and contents Why is C++ Decompiling possible? Intro Modern Day Example Compiler Specific C++ Protocols Intro Global Variables Expressions Return Values Function calls and the stack Local Variables C++ Keywords Intro If statement For Structures Technical Algorithms Practical Decompiling Intro to Decompiling Windows application Decompiling a sample application Special Case: Compiler Specific Compiler Specific: Each compiler is different, such as their CrtlStartUp routines, their statement assemblies (switch , if, while), and numerous other things make each compiler generate different code, even if you compile the same C++ code on two compilers, the end result will be different, because of this I will stick with one and only one compiler, which is the Visual C++ Compiler. 1.1 Intro: 2.1 Intro 2.4.
