It's a HUGE HUGE book that teaches all about electrical components and circuits, It covers everything from Inductors to Sensors to Micro-controllers, from audio to visual components. It even covers the arduino circuitry and how it works and how to work with it. This is exactly what I was looking for because I had bought an arduino a few months ago and haven't used it yet due to the lack of my own experience. Thank you so much Ryan, this has got to be the most relevant, the most interesting, and the best gift to give to a nerd (and hopefully evil genius) like me :D .

P.S Sorry I gave you a hard time looking for a gift, I kinda suck at writing descriptions about myself
