I am still very much a noob when it comes to Arduino. Having fun though...
I want to get a little camera, something along the lines of http://www.sparkfun.com/commerce/product_info.php?products_id=8668, and using the Arduino, log the video ( and possible GPS data at a later stage) to SD card. I am not looking for compression or any other hard work, simple to take the video (not still jpg) and log to sd card. If using a video with composite out is simpler, that is also fine.
Am I being overly optimistic? ::) How about including audio? :P
Cheers, Crispin p.s. I'm guessing HD is out the question? :-[
(kidding on the last one BTW. I know you would need the "Dual Core"Arduino for that. :) )
