“Some years ago I had the chance to drive a C6 Corvette with a HUD and loved it. The ability to see your speed and RPM without taking your eyes off the road made driving much more enjoyable.
For a long, long time I’ve wanted to make a HUD for my own car. While doing some research about OBD2 and Arduino car hacking, I decided to make one from scratch and this instructable shows how you can make one, too!
