The MagPi issue 28 out now! #piday #raspberrypi @Raspberry_Pi

Issue 28 28 The MagPi

The MagPi issue 28 out now!

This month’s Issue is packed with hardware and programming articles. We are pleased to present the first article in an OpenCV (open source computer vision) image recognition software series by Derek Campbell. The robot that Derek used to test the software configuration is shown on this month’s cover.

Expanding the I/O possibilities of the Raspberry Pi is often a first step of electronics projects. This time, Dougie Lawson presents a review of the Arduberry board from Dexter Industries. This little board provides an ideal microcontroller interface for more complicated electronics projects. This month’s hardware articles are rounded off by Karl-Ludwig’s third BitScope article, which includes examples of preamplifier circuits and associated test and measurement.

The Raspberry Pi provides the opportunity to run many different software applications. Voice over IP (VoIP) allows telephone calls to be carried over an internet connection. Walbarto Abad continues his mini-series by describing how to setup an Asterisk VoIP server.

The second application article this month continues the discussion of git (distributed version control system). Git was originally produced for Linux kernel development, but is now a mainstay of many different development projects and has been adopted by several schools too. Alec Clews leads us through his second tutorial on the subject.

This month’s programming article demonstrates how to build an arcade game using FUZE BASIC. Jon Silvera includes instructions, code and images to build a horizontally scrolling game.
