Interested in LCD Gauges?
I'm talking with some lcd manufacturers about custom sized panels. They want to know the number of lcd panels needed to cut costs down for both of us, the more people interested the lower the cost.
Please vote, also note if you have a 4th gen or 5th gen.

As for the design? That's a work in progress.
As for the features I've got a list:
I plan on the mph and rpm to be digital read outs (numbers), and not analog gauges.
The price is almost completely dependent on the lcd panels. But, I'm trying to keep this under $250.
If you guys have any other suggestions for features let me know.

I'm def willing to pay good money for a quality product. So $250 isn't bad at all.
Check out tru vue monitors they make custom lcd touchsreen monitors. I just got them to make me one(capacitive sunlight readable one) for my car pc.

just doing some research here is one guy that did it for his 2003 eclipse
Suggestions, i think i would be better to have a digtal representation of the analog rpm/speedomenter and in the bottom middle of it the digital(numbers) read out
pretty much this is what i'm talking about

I plan on having a basic model that people can choose what options they want to add (od2, tpms, custom colors, etc).
Still waiting on some companies to respond about the LCD panels.
I start prototyping this Saturday......**** I forgot to order some voltage regulators. So maybe Sunday :P

Of course.

This will give you a little taste of some of the stuff I have to do.
Say I was to implement a voltmeter that reads the voltage directly from your battery. The main problem with this is the Arduino board can't handle all that raw power. If you hooked a micro-controller input up to that much voltage you would melt the board (literally).
In order to do this I can use a voltage divider. The great thing about a voltage divider is that its output voltage is a representation of its input voltage (whereas a regulator would output a set voltage independent of the input voltage).
I've already done the math, and decided on a 5000Ω and 1000Ω resistors. The output voltage is as follows:
In -- Out
14v -- 2.33v
12v -- 2.00v
10v -- 1.66v
5v -- 0.83v
1v -- 0.16v
Now we have to do some conversions. We could put every number in between 0 and 14 into the equation and have a map of those results. But that means we have to do it for each 0.1v (which means we have to map more than 140 results). Luckily Arduino will do all the work for us. We can simply give Arduino the maximum and minimum outputs and inputs, and tell it to map the results for us. Like this:
Simple.

{
if(InputVoltage > VmaxCap) InputVoltage = VmaxCap;
if(InputVoltage < VminCap) InputVoltage = VminCap;
return map(InputVoltage, VminCap, VmaxCap, VoutMin, VoutMax);
}
//call the function
int volts = VoltageMap(2.33, 0, 14, 0, analogRead(A0));

This project really got me thinking, i would like to do this for my senior design project(i'm a computer engineering major). Also i saw some of the digital clusters nvidia had as examples. there were two of them that incorporated both analog and digital.

What would be sick is if i would intergrate this with my car pc

I will be calling you. lol
UPDATE:
Major break through in the r 'n d departmant.
I've found a good monitor.
I've found a Arduino graphics card (ignore nvidia).
I've decided to add a back up camera as an option (I guess for ppl who can't park?).

Over 400 views and only 17 votes. :/
Anyways, I was going to use the NVIDIA (according to them you HAVE to capitalize it) ui studio to make a better img of the cluster. But, it crashes as soon as I open. Guess NVIDIA doesn't like Radeon. xD

Hi Michael,
There are some opengl features that we need that are only available on NVIDIA graphics card. Thus you would need a NVIDIA graphics card. All recent graphics card with an updated driver should work out of the box.
Cheers

I said it.

P.S.
I may need a few volunteers to let me probe your car.
