Welcome to the eighth edition of The MagPi magazine,
It’s Christmas! In this issue we hope to entice you into some festive projects to try after gorging yourself to the brim with Christmas pudding.
In this month’s edition, we introduce you to a simple home automation project allowing you to control lights and appliances in your house using the power of the Pi! Just in time to catch Mr Claus! We get your Skutter project in motion with Morphy’s article on adding wheels to your base. Gordon teaches us how to light up a Christmas tree, we have more on using the Pi to control an Arduino and Ben describes how to control servos attached to the Pi using the internet! If this isn’t enough we have more of the old favourites plus an introduction to SQL.
As always, we have some great prizes for you to win in our monthly competition. The MagPi would like to say a big thank you yet again to PC Supplies Ltd who this month has outdone themselves by offering up for grabs a 512MB Raspberry Pi!
In addition to this we have some exciting news for you this month. As of December 1st, we at The MagPi are so excited to be able to offer our readers the possibility of a printed version of all eight issues of the magazine! This is something which gets constantly requested of us from our readers. All eight issues will be beautifully wrapped up in a limited edition MagPi binder making it a great gift to yourself or any of your loved ones of any age. For more information on this please visit www.kickstarter.com/projects/themagpi/the-magpi-magazine-from-virtual-to-reality.
On behalf of the whole team, thank you again for all your support. We hope you have a fantastic Christmas and we will see you in the New Year (1st of February).
