welcome

Raspbian has had its biggest update ever thanks to a dazzling new desktop environment called Pixel. This huge software update gives you a desktop environment that wouldn’t look out of place on a personal computer, rather than a microcomputer like the Raspberry Pi. Read on to discover how to use Pixel’s crisp new interface and all of its new features and programs. If you’re going to start using Pixel as your default desktop, you might also want to create an email monitor to alert you to incoming messages using Python. If you prefer to get hands on with you Pi projects, you can also discover a Wi-Fi-enable walkie-talkie, how to hack your toys and bring them to life, as well as make a game with Sense HAT.

master pixel desktop

Pixel (Pi Improved Xwindows Environment, Lightweight), is the latest iteration of the Raspbian desktop. The major changes are apparent the first time you boot up – the multitude of boot messages has been replaced with a simple splash screen with the release number. There are now 16 stunning desktop background images to choose from thanks to Pi Foundation developer Greg Annandale. The icons on the file manager, task bar and menu now have a crisp, professional appearance. Menus are also cleaner and more readable as application icons no longer appear by default. The rather clunky windows we formerly knew in Raspbian have now been replaced with rounded corners and a modified title bar. The infinality patchset also makes for much cleaner font rendering. RealVNC Server is now bundled to allow you to easily…

how to turn a raspberry pi into a walkie talkie

Where did the idea for talkiepi stem from? I had the idea a few years ago to use a Raspberry Pi as a walkie talkie, but it wasn’t until I watched Stranger Things that I got the itch to do something for my kids. Kids nowadays have smartphones and tablets, but they don’t have any simple single-purpose electronic devices that do one thing well. I had recently purchased a 3D printer, the Monoprice Select Mini 3D to be exact, and had started tinkering with Fusion 360, so I thought it would be a great project that I actually had all the tools and hardware to see through to completion. Did you encounter any significant problems when building your Wi-Fi walkie talkie? It was about keeping it simple and kid-proof. I found the cheapest…

make an egg-drop game with the sense hat

Some of the most basic and repetitive games are the most fun to play. Consider Flappy Bird, noughts and crosses or even catch. This tutorial shows you how to create a simple drop-and-catch game that makes excellent use of some of the Sense HAT’s features. Start off by coding an egg – a yellow LED – to drop each second, and a basket – a brown LED – on the bottom row of LEDs. Use the Sense HAT’s accelerometer to read and relay back when you tilt your Sense HAT left or right, enabling you move the basket toward the egg. Successfully catch the egg and you play again, with a new egg being dropped from a random position… But, if you miss one, then it breaks and it’s game…

hack a toy with the raspberry pi : part 1

Combining an old toy and a Raspberry Pi, you can embed a selection of components to create your own augmented toy that responds to user input. For example, take a £3 R2-D2 sweet dispenser, light it up, play music and stream a live web feed to your mobile device. Part one of this two-part tutorial covers setting up four basic features: an LED for the eye, a haptic motor to simulate an electric shock, a webcam stream from a hidden camera and the Star Wars theme tune broadcast to a radio. You may choose to combine these with your own hacks or use them as standalone features in other projects. Don’t feel limited to just using a Star Wars toy either – we used the R2D2 figure because it was cheap,…

check your mail

Since the Raspberry Pi is such a small computer, it gets used in a lot of projects where you want to monitor a source of data. One such monitor you might want to create is a mail-checker that can display your unread emails. This issue, we’ll look at how to use Python to create your own mail-checking monitor to run on your Pi. We’ll focus on the communications between the Pi and the mail server and not worry about how it might be displayed. That will be left as a further exercise. To start with, most email servers use one of two different communication protocols. The older, simpler one was called POP (Post Office Protocol), and the newer one is called IMAP (Internet Message Access Protocol). We will cover both protocols…
