Using pi 2 to make an arcade. Right now it's just a portable arcade but soon I will make a full blown arcade machine this is actually the project that got me two love electronics when I was 11 now I'm working on a different project. The arcade was kind of frustrating in the beginning but once you download retro pi and get it set up your almost done. all you have to do next is buy the buttons and the micro controller. And once you have wired it all up then it is down hill from there.
