Welcome to issue 11,
The Raspberry Pi computer opens up many opportunities. It can be used as a web server, print server and as a wireless access point. If the problem can be solved with a low power Linux computer it can be solved with a Raspberry Pi.
This month we present some more articles which demonstrate how versatile a Raspberry Pi computer is. There are hardware and automation projects and several programming articles to choose from. We are pleased to provide a first assembly article and hope to see some bare-metal coding in the future.
Lastly, thank you to all of those who have ordered Volume 1 (Issues 1-8) as part of the Kickstarter project and through PayPal. We are very grateful for your continued patience. We are also pleased to announce that the binders and stickers have been printed and several of the issues from volume one have been submitted for printing. We hope to be shipping Volume 1 very soon.
If you can dedicate some time to help with article layout or testing, please email email@example.com.
