Thanks..
I'll ask the guy to make some footage of it once it is mounted in the miata. I havent got a chance to test it yet, my mazda familia uses a different ignition system. Might try it on moms miata if the opportunity arises.
The little black box is approx. 5cm wide and 2,5cm deep. It is meant to be mounted on the steering column or wherever in the line of sight.
The bigger red box contains the Arduino and the interfacing PCB.
Could have tried to stuff the transistors in the little box, but it was nigh impossible since I had to assemble everything inside the box (because it was impossible to stuff the leds back into the holders when attached to the PCB).
For anyone interested in the supply part of things, I'm using some pcb's taken from DealExtreme car USB chargers (5V, 1A), and am feeding that directly into the 5V pin of the arduino. Cheapest way to get reliable power without overheating the linear regulator of the Arduino.
Anyway, this way I have room for expansion.. I'd like to tap into some important sensors like oil pressure and temp so I can use the red LED as a warning light.
For my own purposes I'm planning something a little more ambitious.
Busy putting together something that will allow me to log:
-sensor data
-rpm
-accelerometer data (wiichuck offcourse)
-gps
And then throw in an LCD or other type of display for eye-candy's sake. My brother is busy putting together some code in matlab that plots gps data onto google maps tiles (coming together nicely).
Would be nice if I could get a laptime display too.
Sort of poor mans datalogger, I'm guessing I will have to use my Arduino Mega for that project.
