I had this brilliant idea (so I thought...) of measuring engine speed (rpm) without having to go into the engine bay and meddle with the ignition distributor wiring. As such, I scrapped my plan to work on the 2-axis accelerometer and the odometer estimator and focus on this one instead.
Over the past few weeks I've been figuring out how it should work, it turned out that it was not as easy as I thought. And I was just about to give up when I managed to get it to respond the way I wanted it to.
Currently, it is still on the breadboard and the display is still on my laptop (using Selmaware's StapPlotPro). I plan to get it fixed on vero/strip board and use 4 pieces of 7 segment displays. Will start doing it today if possible.
The good thing about this engine rpm meter is that you do not require any connection except to the cigarette lighter socket for power.
This is the only thing that needs to be connected to your car.... Simple and easy..!!!
I will post more info when I'm done. Not sure whether I will post the schematics and source codes though....
