Vehicle instrumentation with Data Logging

Projects General Guidance
1

Hello!

I'm after some advise on which Arduino board to go for to get the best possible outcome for my project.

My project is to create the Vehicle Instrumentation for a Electric Formula vehicle, so it must display speed,rpm, current, torque, battery conditions etc. to the driver. Therefore I am looking at LCD / TFT displays approx. 3"+ to make it easy for the driver see. I believe there are limitations on screen size for the UNO board with a dedicated GPU shield which seem to be expensive. So I could use sets of LEDs for some of the measurements that don't need accuracy - like in this example http://arduino.cc/en/Tutorial/BarGraph

The second part of the project (the one i'm hoping to start with) is data logging. I need to be able capture real time data, save it, and plot it on a graph. Ideally this needs to be done wireless for when the vehicle is in development i.e testing on the dyno. I have come across the plotty API which would seem to be perfect for this. http://vimeo.com/89003132

At the moment I am looking at the Arudino Yun, mainly due to the Wifi being built in - it seems more cost effective then buying a Wifi shield. Although I am concerned on the limitations for the size of display.

Hopefully, its given you an insight into my project. Any advise would be great as this is my first project with an Arduino - I am used to older PIC development platforms.

Thanks, Josh.

Sorry to bump a fairly new thread, but could someone shine some light on the possibility of me using the Arduino Yun. Would it be best suited and cost effective?

That display would be perfect if it works. I don't need anything graphical just text really.

By not having wireless would save a fair amount of money, however it will make development of the vehicle a lot easier. We are currently also designing the motor controllers and are wanting to do test runs.

I have my own rpi and have done a few projects with it. However I find C coding on it/for it very frustrating. There are some fantastic displays available though.
