Here is something that I put together that is pretty simple, but nice to have..
I obtained a 9" LCD TV that runs on 12V DC and the idea was to provide a spotter a way to see what I am seeing while flying with my Fatshark goggles.
I use 5.8 GHZ for video and my goggles have a 5.8 GHZ receiver module that installs right into the goggle so it is a wireless solution and very convenient, and there is no "ground station" in this scenario that I am using.
I wanted to provide a spotter a way to see what I see, and also I wanted a method to record my flight as seen through the goggles during my flight.
I picked out a LCD TV with attributes that make it easy to incorporate into a FPV system. First, it doesn't blue screen when the signal is weak. because some dropouts are expected from time, a monitor that doesn't go into a blue screen mode is good.
Also, I wanted it to run on 12 VDC because I am using a 3 cell LIPO to power the monitor, the receiver and the DVR. I found a suitable TV and got it.
I simply used velcro to mount the battery, the receiver and the DVR to the back of the TV. I used some poster board to fashion a "hood" to help shield the screen from direct sun light. I used a immersion RC UNO receiver with a fatshark RH spiral polarized antenna to match the transmitter antenna. The receiver has two video outputs, one I connect to the TV video in, and the other one I connect to the pocket DVR, which records to the SD card. I know it doesn't look great as a package, but later I may install in in a briefcase or something.
This works quite well, I use it even when I don't have a spotter or interested companion, because it is interesting to view the video along with the OSD info that streams across. Here are some pictures:
