both of these are simple requests for the Leaf.

Kudos for you! I knew someone would pick up on that. :D Seemed appropriate.

Obviously, I can tell you the answer to that for the Leaf easily enough, but I did write the code to put the device to sleep if there is no traffic for 5 seconds and will wake up on traffic even if the Leaf is off. One of the things I am looking for is some indication of the energy used by cabin heating and AC for better DTT computation. It must exist since you can see this in the Energy Info screen but isn't used in the car's built-in DTE calculation (uses some formula or look-up table instead of the actual climate control power).

I know less about the Rav4. If they come down in price I may find myself learning a lot more... ;)

The current price is in the mid $30k range. I don't know what competes with over 100 mile range, that is physically larger than a LEAF, far more room for stuff inside, and has beau coup power.

Oh, and proper designed climate controlled battery cells.

Why 2 displays? It seems like one would be plenty to display everything and would greatly shrink the unit down.

True. One is probably enough but I wanted the second mostly for aesthetic reasons and had a very specific space on the dash I wanted to fill. I wanted the final assembly to be closer to the same width as the center console it is sitting above but no more than 3 inches tall so it wouldn't obscure visibility. I tried to find a short wide display but quickly gave up and settled on the dual.

will the enclosure be at a place where you could put a camera facing the front of the car and record video in a loop while the car is on? with a usb drive or sd card, this would make your Geekathon Canary a great accesory, not only for propeller heads.

Yup. If you look earlier in this thread, you'll see this as one of the future enhancements. There are already several people sharing code to do this with this micro-controller.

I would mention, though, that I won't be able to display video. Snapshots, yes, but I had to use a single wire interface on the displays since I needed to use the other io's for the other features (can busses, touch screen, 12v monitor, speaker, USB connector, etc). Plenty fast for text and basic graphics, but not video.
