I'm wanting to build an Arduino based flight control panel with buttons for toggling RCS, SAS, gear, ect. That part will be easy. What I need help with is writing a plugin for KSP to output game state data like fuel levels, electric charge, alt, and velocity via serial port. My plan was to have the Arduino buffer this data and then write it to a LCD screen. If someone is interested in helping with this, if it's even possible, when I have a working prototype I will post details on how to build the flight controller and the Arduino code so anyone who wants to get their hands dirty can have a nerd toy of their own.
