Ok, for the longest time I have wanted to have digital gauges in my Jeep. This isnt an offroading machine (at least not yet cause Im still in college til Dec and thus have no money). This is my daily driver, and I would like to have a little input from you fellas and get a little help or advice.
I want my gauge to look like this mspaint rendering I made :
I want all six gauges on there in 7 segment and 16 segment display units. I want to use blue as shown, but I might use green. Obviously fulltime/part time wont show until active, along with "brake" and hi/lo beams.
My idea: using a basic stone aged computer running a simple program (of which I dont know what, and this is where the computer tech people come in) write code that recieves voltage data from the gauge sending units, and converts into the appropriate readout.
-convert volts from battery into....nothing actually, just display the voltage reading.
-convert voltage from oil into a range from 0-80
-convert voltage from fuel sending unit into a percentage
-take voltage from stock tach and convert into a 2 digit reading
-temp sending unit from volts to reading of 0-260 degrees
-my MJ doesnt have a mechanical speedo hook up on the NP435 tranny we are putting in it, so I will use a setup that will read driveshaft rpm a put into MPH
-write a code that uses mph x time at speed to calculate mileage.
Obviously I could use a real computer to do this, but I dont want the lag of start up time, nor the bulk. I want to use something that boots really fast. (Im not HUGE into computers/boards/electronics etc YET, but I am teaching myself.) I do have a few Dell Axim PDAs I could use as the computer, but I would rather just wire a board that does this. I'm going to try to make it plug-n-play, other than the speedo, reading off the inputs in the back of the cluster.
These are all the things I dont know how to do... I am researching to teach myself, but if anyone has ideas or inputs, then please let me know.
This will be going into a RENIX.
I know it CAN be done, but if anyone in the field of computers has input or advice, I would appreciate it.
Thanks alot guys

EDIT: I know this is a large task, but I like challenges and this wont be done in a weekend......or any time soon really
