I’ve been working on this project for about 6 months now. It’s a digital multigauge based on the arduino. In its current form it shows oil temp, turbo pressure, accelerometer readings, a timer, and two misc temps. The code is freely available (though not 100% complete) as are the schematics. I designed the project to be an in car sensor display but one could modify the code and general idea to have a simple weather display, watch stocks, view environmental readings, check on a robot’s health, etc.
