Issue 9

February 2013


Welcome to Issue Nine,

Many thanks to all of you who generously supported our Kickstarter project. The Kickstarter raised over four times the target amount, with 616 backers. After a small delay, we are gearing up for printing. The folder design for Volume 1 (Issues 1 to 8) has been finalised. If you missed out on the Kickstarter, Volume 1 can still be ordered from our online shop

This month we are very pleased to present an interview with engineer and founder of Adafruit Industries, Limor Fried.  She has been an encouragement to many, providing tutorials, answering questions and supplying parts to build all sorts of interesting projects.

This issue also contains hardware articles, setup instructions for RISCOS and Arch Linux operating systems and our regular programming articles on Scratch, Python and C.
