If you are new to Linux, a raspberry pi is a great place to start. there are some great tutorials on youtube(and really all over the internet) it is just a tiny(credit card sized) computer. you install raspbian linux, and just start playing with it. They were originally designed for kids to learn about computers, but they have become powerful enough, they can be used for lots of different applications. Be warned though, once you figure it out, they become addictive. I have Ham radio sites across a few mountain tops, and have raspberry pi's running in those locations, and another 8-10 at home. jusst take 10 minutes and watch a Youtube video about the pi, I promise you, it is a great learning tool
