I’ve got a J120 board from Jurgen at Auvidea.ea and a TX1 board. The J120 board seems to work pretty much as advertised. It’s small enough to fit on a medium sized quadcopter (won’t fit on a small IRIS) and it comes with the various cables needed to connect it fairly easily to a Pixhawk.
The first step I’m attempting is get the board up and running with MAVProxy (works!), OpenCV, Python, Dronekit. Sadly the software that comes with the TX1 doesn’t support WebCam + OpenCV + Python. Apparently using a non USB camera or using C++ instead of python works.
I’m also attempting to setup the board to act as a wifi access point so that we can connect a GCS to it easily using Wifi but sadly that’s not going well yet.
Yet another challenge is that I’m not yet sure how to save/restore images. With an RPI it’s quite easy to make images to share with your friends but so far I have not figured out how to do that with a TX1.
