An introduction to Practical Electronics, Microcontrollers and Software Design is a PDF book (700 pages+ and growing) that I have written for my students who are starting out in electronics. It is based around the PCB CAD software Eagle, the ATMEL AVR microcontroller and the BASCOM-AVR cross compiler. It aims to help students use software like Eagle and Sketchup for their chosen projects, and how to write and plan successful code using statechart principles. There are many examples of block diagrams, circuits, layouts, flowcharts, statecharts and code in the book for many different interfaces and products. (The latest update includes 35 pages on using the SSD1928 and HX8238 color graphics LCD controllers with ATMega644)

All money received from the sale of the book will be given to support work of 'Children at Risk' an organisation in Cambodia supported by the church I go to. I think the book is worth $15USD (about $20NZD) and its for a great cause. Along with the book you get access to any full versions of my software.
