After being interested in FPV and areal video. I wanted to use my GoPro Hero 3 Black Edition as a video camera for FPV. I read about a special cable I had to buy, but on one hand it was pretty expensive and on the other hand it looked very bulky and heavy.

So I found and article of David Windestal, in which he describes how to build your own lightweight video out cable: rcexplorer.se/diy/2012/11/diy-gopro3-video-out-cable/

Having that read I ordered those proprietary 10 pin mini USB connectors from China.
And finally built it my own! 😉

Here are some pictures and a video below:
