No Starch Press have a 'pay as you feel' (mostly) bundle available covering FPGAs, game consoles, circuits and Arduino available now:
https://www.humblebundle.com/books/electronics-for-the-curious-no-starch-books
It also includes "Arduino Project Handbook" by Mark Geddes which I helped bring to print by testing and proof reading the projects.
Has anyone checked these books out before?
