4reel: a low-cost stereo depth camera board for hardware hackers

Two OV9281 cameras and a tiny Rockchip RV1103 running Linux on one board. It works out depth by block matching in the chip's video engine, and it can send depth over serial to an Arduino or run on its own. The first revision had a few bugs, and the maker plans a small batch of fixed boards if enough people sign up.
