Gas prices are on the rise again, and it got me to thinking. I remembered a device from the 70s, that calculated MPG, but don't remember much about the details (wasn't driving yet). Seems like there must be a simple and cheap way to measure the flow rate of the fuel, and distance traveled, pretty simple calculations, and a 2 digit display should suffice (unless you install an HHO system ). The point being, that changing your driving habits, can dramatically reduce fuel consumption. If you see the numbers rising and falling, you can quickly learn what to avoid, and how to improve.
I don't know if I'll get around to building such a gadget, have quite a backlog of things to build, and in the works. Figured posting this might give a college kid something to turn in. Or maybe somebody looking to make some quick cash, since if it's cheap enough, and easy to install, plenty of people would jump on it.
Mostly, I guess I'm a little curious about whether modern cars already have the input information already available. Who knows, maybe it's already installed in those fancy new cars (mine is a '91 Explorer, gas gauge doesn't even work), lots lights, bells, and beepers...
