hi guys
I am a final year student of bachelor of Computer Engineering. As my final year project i am required to digitize all the displays present on the dashboard.that include the tachometer the speedometer the fuel and temprature guageand other realted items. Before converting them to digital i must firat know how they work. So can u please explain me their workin. I think that regarding tachometer when we step on the accelerator the current increases and the rpm needle moves . I wana know how the current varies.Also plz tell me how can i covert all these items to digital. Would i be requiring analog to digital converters. I fu have answers to any of my question plz reply and also plz send me if u have some useful links. Ill be refering to u guys from time to time as my project progresses
Thanking you in anticipation.

Actually It's been my experience that electrical engineering degrees teach you jack shite. Most of the practical stuff I learned was from hanging out with the electronics technicians who ran the labs. They were really cool, and drank scotch. Umm... scotch... Anyway, the degree only puts you into an environment where you *might* learn some stuff. Then they give you so much coursework that you never have time to really *think* about what it is you are doing, so you never actually learn anything directly. I found the most useful stuff I learned was from talking to random people in the department and asking questions. I picked up SOME stuff from my courses, but most of it was very introductory. The only good thing about it is that now I know where to look if I need to know something in particular, and I've been given enough of the 'language' to be able to understand new stuff as it comes along.
I got crappy marks in my undergrad, and only got into grad school after a long battle with graduate studies.
Now my students in the labs I teach wonder how I learned so much stuff. The secret is hanging out on forums like this and getting your hands dirty and blowing stuff up, and asking smart people practical questions.

Number one, try posting to the correct forum.
Number two, read books. All this info is completely elementary. Car sensors (for any car that is not ODB-II) are very simple devices.
Number three, how can you not already know this if you are a "final year student"? Now that I think of it, I used to get a tonne of email from "final year students" wanting to know very elementary things...

you could find alot of this on google.
i mwould put a crt or a cld in place of the meeters. then use a computer in the trunk to take in the info and spit out an imige
