 ### Thanks Henrik!
 For those who don't know, Henrik made [a board](http://hforsten.com/making-embedded-linux-computer.html) based on Atmel's SAM9N12 SoC roughly a year ago. This is what showed me as well as likely hundreds of others that such a thing is possible to do at home without thousands of dollars in equipment. His fantastic walkthrough is what inspired for me and guided me through nights of confusion and bewilderment, and if it weren't for him and his walkthrough this would have not been possible. So, Henrik, thank you!
