When i first thought of it i looked at the Amarino Android kit looks very nice and might be the best way to go. I have left this to the wrong time of year, I should really have looked at it when the nights were dark and cold
Morning,
With the huge reduction in the price of 7" tablets i have been wondering about creating a second dashboard with one. I wondered if anyone knew
of any existing projects out there before I look at doing a scratch build because there is a lot of work to build an interface for the sender signals
and the software side of it
Some discussion here. Most I have seen use the CanBus/OBD2 for the interface, not what you need I think?
If you want to hook up to senders etc, I would probably suggest getting an Arduino dev board and the Amarino Android kit.
I've seen this done on a home built plane in California. It had a two switchable displays, one for the engine/flight monitoring and a second for
navigation.
It was a good piece of kit but, when I asked how it worked it all came across as gobble-de-guke. It's probably simple, but beyond me.
If you have a megasquirt ecu it already exists in several flavours
unfortunately Im using the stock r1 engine management.

This may cut down on the interfacing work for you

Steer clear of any thought of using Bluetooth, go for a USB based interface as it has much better latency characteristics and throughput.
If you do this with Arduino then go for the mega board because it has more inputs (hence more flexibility).
I'd worry a bit about how to deal with rev counter and speedo (fast triggers) owing to the way that the programming works (it is all sequential
stuff). I had a speedo working fine, but not sure what would happen if a speedo trigger coincided with a tacho pulse.
The ADC's on Arduino are not that fast either.
But cheap and easy to play with.
