OT but what were you going to use for this?[/quote:2jpyclk1]
There are a few things that end up as extra gadgets dotted about the dash that I'd rather converged into a single device:
My IBS beeps at me when I'm using the Stirling DC-DC charger because the different charge voltage confuses it, and I'd like to be able to switch between DC-DC and regular split charge on the device rather than with a seperate toggle switch. So it will include a split charge control with 2 control outputs I can cycle between and it will know output 2 is allowed to have a different charge voltage!
My BOAB Trip meter is a bit awkward to mount and neither the BOAB or OEM trip meters can tell wether I'm on LPG or petrol making it much harder to estimate MPG. So it will include a trip meter with an extra 2 counters, one each for LPG & Petrol, only one of which will run depending on which fuel is in use.
I'd like alarms and or readouts on the coolant and auto box temperatures so it will have some instrumentation for that.
Sounds complicated but it's just a pic chip with a few of it's A2D converters hooked up. The hardest part has been deciding where to put it In the end I've decided on DIN sized to use the slot under the stereo and use a pair of 2x20 LCD's side by side with one displaying instrumentation and the other showing trip data.
But if there's a commercial device that already does most of that then I'd buy instead of build.
