Here is a little DIY project for anyone who has mad hacking skills and a desire to pimp out their car’s dashboard.
This digital dashboard gauge is built on an open source Arduino platform with text LCD and standard car senders. For the purposes of this hack, the gauge is being used to monitor turbo pressure, oil and other temperatures, acceleration and provide a lap timing, but the author stresses that “the code could be easily adapted for other applications (experimental purposes, weather monitoring, pet monitoring, personal health meter, RC car telemetry, robot telemetry, etc.)”
Instructions are available in the forum thread. You can also check out a demo movie here. � Sean Fallon
