Convert Analog Gauges to Digital
OK crazy if not impossible question.
How should I go about changing my stock analog gauges to digital (you know, like the old 80's and 90's vehicles with the sweeeeeet clusters)? Might it be possible to just keep the gauges the way they are and put the digital display over it? There is a good inch or two of empty space in front of the cluster. What I would do is make my own board and cut out custom slots for individual LEDs and leave the bottom right area somewhat open so that you can still see and scroll through the computer...
The issue is how do I get the LEDs to light up at the correct speed, rpms and fuel level? These must be monitored by the computer since it knows you fuel economy and range, so is there a way to get into the computer or hook something up so that when you are going 20mph the correct number of lights will go on?
OR is there a way to set up sensors on the actual speedometer face? (1 per mile per hour may be difficult to do though) and when the needle when over the sensor it would turn on the corresponding LED and when you went slower it would flip it off?
OR (ah ha!) take off the needles and put a gear (or something... I'll just call it a gear) over the now empty knob... connected to the gear (or whatever... I don't know) have a contact (like a circuit board) and like in the previous possibility, when the gear moves whatever is connected to it will move across a circuit board with individual "cells" each corresponding with 1 mph and if you were going 20mpg... oh my... 20 LEDs wouldn't go on... it would say digitally "20" so you would have to make all kinds of circuitry... oh my... I have no clue...
