I'm enjoying watching progress being made, even when it isn't.
Keep up the good work.
I'm sorry to hear that your "re-purpose an existing display" scheme isn't working for you so far. Are the clock and temperature gauges pretty much the only ones that had potential?
Regarding the "install an external display" plan, I still would like to have the option of using the display that I already haul around every day: My smartphone. "Need to see your SOC? There's an app for that."
Also, if one was able to get certain data into
a smartphone or tablet, wouldn't it then be possible to pipe that data onto the Leaf's nav display, perhaps as an RSS feed or something? It seems silly to have to send that info through the internet and two separate cellular connections, but it might work in a pinch. Maybe.
But a "dumb" display wouldn't be bad either, and would have a lot less dependency on user-supplied gear and software. Would you be able to use one of the many existing "OBD-II gauge" products, and feed it some suitably massaged data?
