  • How to build a $200 smart drone with the Pi Zero

    Erle Robotics, which I mentioned in last week's piece about the increasingly important role of Linux in robotics, supplies cheap components for DIY Raspberry Pi projects. I got in touch with the makers at Erle this week to come up with a great tutorial for our readers.

  • Add a battery pack to your Raspberry Pi

    Your Raspberry Pi’s mobility is usually restricted by the length of the power lead. Rather than limiting it to your desk or living room, however, you can use it for mobile projects as diverse as launching it into near-Earth orbit or monitoring and automating your garden.

    Of course, to do this you will need batteries, but adding battery power to your Raspberry Pi is simpler than you might have imagined. All that is required are six rechargeable AA batteries (or single-charge alkaline), a battery box with space for the batteries and a UBEC. The latter is a Universal Battery Elimination Circuit, a voltage regulator that will regulate the power supply and prevent damage to the Raspberry Pi, and can be bought for under £10.

Open is the solution to improving 21st century education

Much of the Internet runs Linux and open source software, yet in most of our schools—whether PK-12 or higher education—Linux and open source software are given short shrift. Linux has made serious inroads on hand-held devices, the desktop, and the Internet of things (IoT) that use platforms such as Raspberry Pi, Galileo, and Arduino. Despite this astounding growth, a relatively small number of secondary and post-secondary schools offer technology training that prepares students for increasingly in-demand technical skills. The growth of the maker movement and the concurrent interest in STEM skills, which include coding and ethical hacking, may provide a much-needed impetus to change this trend. Read more

Dale Raby: How do you Fedora?

Dale started using Linux around 1999 when he became disconcerted with his Windows 95 computer and a young clerk in an office supply store told him about Linux. “I started reading some of the magazines, most notably Maximum Linux and eventually got to know their senior editor, Woody Hughes and Show Me the Code columnist Mae Ling Mak,” said Raby. His first distribution was Mandrake 6.5 which came in a box with a boot floppy. Raby manages a small gun shop in Green Bay, Wisconsin. He is also an author with four published books: The Post-Apocalyptic Blacksmith, 777 Bon Mots for Gunslighers and Other Real Men, The Wives of Jacob I, and In the Beginning. Read more
