Raspberry Pi gets an official touchscreen display

Although it's pretty easy to hook up a Raspberry Pi to a screen using its HDMI port, it's not exactly the most portable of solutions (especially if there isn't a TV or monitor around). The Raspberry Pi Foundation recognized this, so it set about finding a "simple, embeddable display" capable of giving Pi owners a screen from which to work from, but that also embodies the DIY spirit of the board that it connects to. It's taken almost a year, but the official Raspberry Pi touch display has…

The main reason behind the incredible popularity of Raspberry Pi is its usefulness. The small computer can be used for a number of fun projects that not only satisfy certain needs but also are fantastic educational tools for people of all ages. One of the most popular things to do with the Pi is to turn it into a capable home server. Such server can host a website, give you an easy access to your music and video files, or let you share a printer between different computers. The whole thing…
