Figured i'd share a little project ive been tinkering with. Running a model train with a Raspberry Pi. No, i didn't write the software, i have enough trouble just navigating Linux. Takes a while to load, but is super stable once it does. The walk around is my Ipad, that controls the JMRI software on the Pi.
