As it stands, my plan right now is to create an instrument panel game controller , using a TI Launchpad and some accessories. I will be designing the controller in CAD and then having it laser cut. I also want to have a joystick 3D printed or laser cut. I will be coding in C on the launchpad, but I will also be writing the profiling software on my PC which will require Java and C#. I plan on using the Java Robot API to simulate keyboard and mouse action. I may also add some gameport components and try my hand using the JInput library.
Once I have all my parts decided upon, I am going to use a dial caliper or micrometer to measure them and build the whole thing in Autodesk Inventor.
