Ever since I was old enough to drive, I've dreamed of having a car with a computerized dashboard, but it seemed out of reach until recently. With the advent of affordable tiny embedded computers like the Arduino and Raspberry Pi I was finally ready to make this a reality. I wanted a system that could grow with my dreams, so I created CADI, an open source Computer Aided Dashboard Instrumentation system. I'll take you with me from concept to integration, taking a look at how I choose my hardware, what I've learned trying to integrate with my car's electronics, what it can do today, and where I'd like to take it moving forward.
