[Justin N] sent in one of his projects. It’s a digital dashboard gauge for his Subaru. It’s built around an arduino board with a text LCD and standard automotive senders. He’s using it to monitor oil temp, turbo pressure, temperature, acceleration and provide a lap timing. The details are buried in this forum thread, but its worth a look if you’ve spent time geeking out on your car.

I’ve added more info to the first post in the thread to make life easier for everyone. It is incomplete, but I will try to upload code/diagrams when I get a chance.
Would this make a good base system for a HUD?
It could. It is essentially a bunch of off the shelf components put together for a greater functionality. You could swap out the lcd with some sort of HUD. I have no idea how one would go about finding or controlling such a piece of hardware though. I’m guessing that it would probably not be controlled via a serial interface and you may have issues with space on the atmega microcontroller. Currently what I have flashed on there takes up about 9-10k of 14k.
Hahahaha my 2.5rs is next!!
