How to build electronic devices on your own Building electrical devices is probably the most inexpensive engineering you can do because most electronic components are very cheap, like less than $1. How to actually build devices on your own isn't taught enough in engineering courses, so here's a quick summary of how to get started making devices like I have on my site. In this page, I kind of assume you're an engineer/scientist of some sort (or studying to be one) and that you've already had a few electrical engineering classes. If you don't know any electrical engineering, you'll obviously need to learn the basics before you can start inventing. A good place to start is the book Make: Electronics , which teaches you theory and practical knowledge of components at the same time. First, get an idea To get an idea for something cool to make, it helps to go to online stores for electronic components (Jameco.com is a good one) and look at the components they have. Also, I really recommend getting a microcontroller, like the Arduino. . .
How to Surf the Web Anonymously" The Internet has a way of lulling you into a false sense of anonymity. After all, how can anyone know your true identity in a virtual world? The truth is that simply by connecting to the Internet, you share information about your computer, your geographical location and even about the Web sites you visit. The goal of anonymous Web surfing is to circumvent the technologies that track your online activity and may potentially expose your personal information to others. By surfing anonymously, no one knows who you are, where you're connecting from or what sites you are visiting. When people think of surfing the Web anonymously, they automatically associate it with extramarital affairs, malicious hacking, illegal downloading and other sordid behaviors. As you'll see in the next section, surfing the Web anonymously isn't as easy as erasing your browser history.
