Create a Digital Dashboard for an Old Car With a Raspberry Pi
Have an old pre-OBD-II car but still need a fancy data screen ? DIYer 240SF on YouTube has figured out how to use a Raspberry Pi to add a digital display to an older Nissan with a consultation port that can probably be applied to a number of different systems.
The dashboard displays the current speed, RPM and coolant temperature. In this case, it receives data from the Nissan Consult port, runs it through the software, and then displays it on a screen powered by the Pi. As it stands, this is written specifically for those specific Nissan ports, but the concept can be adapted to something else, provided you can rewrite the JavaScript file on GitHub. Of course, there are many other ways to do this if this one doesn’t work for you.
