If you're like me and you're flying FPV with some older Fat Shark goggles, and would like a quick, easy, affordable way to add a DVR to record your flights with, then check out the Makerfire Mini DVR. This little DVR has a built in battery, so there is no need to connect it to an external power source. This makes it perfect for attaching to FPV goggles that don't already have a DVR. The problem I have seen some people have with these DVR's is that they aren't out of the box compatible with Fat Shark goggles, or other brands of goggles that use a standard A/V 3.5mm plug configuration. Why they manufactured it like this is beyond me, however it is a very easy fix. In the images below you will see that the signal order of the cable included with the DVR has the ground, and video lines reversed when compared to the plug configuration needed for our Fat Shark goggles. The fix is to simply cut the included cable in half (or shorter like I did). Since you will be splicing the cable back together anyway now is a good time to adjust the length to fit your needs. Now that you have the ends of your cable open you will need to strip the 4 individual wires inside enough to allow you to solder (or crimp if you prefer) them back together. This time however you will reverse the red, and black wires, and connect them red to black, and black to red. This will put the ground, and video signal wires in the correct order on the plug for proper communication when plugged into your goggles. The first image below shows the plug order for the Fat Shark goggles. The second image shows how the cable included with the DVR is wired. The video below is taken with the Makerfire DVR attached to my Predator V2 goggles, and I have also used it on the Teleporter goggles that I use for passengers. If you have any questions about the process feel free to ask, and I will do my best to help. Happy Flying!!
