Title : Raspberry Pi for Secret Agents Edition : 3rd edition Year : 2016 Authors :  Matthew Poole Publisher :  Packt Preface The Raspberry Pi was developed with the intention of promoting basic computer science in  schools, but the Pi also represents a welcome return to simple, fun, and open computing.  Using gadgets for purposes other than the intended ones, especially for mischief and  pranks, has always been an important part of adopting a new technology and making it  your own. With a  £25 Raspberry Pi computer and a few common USB gadgets, anyone can afford to  become a secret agent. This third edition by Matthew Poole takes the previous edition's projects and brings them  up to date to now support the new Raspberry Pi Zero, Raspberry Pi Version 3, and the  Raspbian Jessie operating system.  There is also a new chapter that looks at ways to connect sensors and gadgets to our Pi to  protect ourselves against other would-be secret agents.
