I thought it might be handy to have some kind of box to place the small DVR recorder as well as a 5V BEC and two Plugs to connect everything easily. The parts are the base and the cover. I used two cinch sockets from an old SCART Connector as well as a small 5V BEC ( http://www.banggood.com/3A-UBEC-Module-Low-Ripple-Bluesky-Mini-Switch-Mode-DC-BEC-5V-12V-2-6S-Supply-p-993056.html?p=5I2013540154201404DT ). The box features some holes for the power connector (I used a red JST connector), the video out plugs to connect a display or your goggles, the two cinch sockets and the micro SD card.
