Yes, a little bit 'techy', I use something similar in my custom home automation system :-) Will be interested to see how you get on. I've been looking at similar solutions. I need quite a few digital inputs and analogue inputs though.

I would separate the display electronics from the sensor processing. Use the display to poll a series of Arduino modules, which then respond with their data. You can then add more functions in the future without having to hack your display unit around. Don't forget there is also an Arduino Mega which has a lot more I/O pins than the standard one.

The adk board has about 50 digital in/outs of which I think 10-15 support PVM. It also has 16 analogue inputs.

You can measure most things pulse related with the digital pins I think so the small number of analogue pins shouldn't be an issue.

I haven't got very far with this so don't take this as gospel but there's a lot of information to pick over here...

The main issue you will have is temperature.

Most COTS panels are rated for around 5degC to around 40degC, not much use on a cold winters day or hot summer day (if it's been sat in the sun and turned on)

Raspberry PI is not designed for automotive use and will also suffer from the same temperature issue.

Then there is EMC (Electro-Magnetic Compatibility) i.e. will it interfere with the systems on the car or other things around the car (e.g. engine management or your radio reception, tv, mobile phone etc.)

If you were building it for a production car it would need to be rated -40c to +85c.

No price on this yet but it plugs into CAN BUS, can have a custom logo, G meter, timer, day/night mode and hooks in to the car's odometer etc.

1280x800 resolution 10.1" screen.

This looks interesting and no doubt expensive!

Dredge up an old thread! Just been reading http://www.pistonheads.com/gassing/topic.asp?h=0&a... thought this connected to a Nexus7 would be an awesome custom display!

Nexus 7 + Bluetooh OBD2 reader + Appropriate app, e.g. torque.

Don't like the idea of relying on bluetooth or wifi connection!

You can enable native USB OTG on the Nexus 7 to use one of the USB cables (with adaptor!), but whether the Apps support it is another question.

I'm prototyping with a Raspberry Pi. I'm using this 9" display now too: http://hdmipi.com/

I had spotted that panel too, put a Can interface on the Pi and connect it to the Megasquirt is my plan at the moment.

It is, especially as it's nothing more than two chips (which I actually have lying around as I'm using them elsewhere in the car) and a few other pieces.

I *could* make up a board (well actually 5, MOQ and everything) but it would be take me a few hours plus a few weeks waiting for it to arrive against it arriving this week and tbh I'm getting to the stage of just buying something rather than spending hours on things that other people can do better.
