This is my latest FPV project. I wanted to make something that would be more portable and easier to use at the field than my original ground station. The solution involved integrating a 5.8GHz receiver into a compact 7" monitor. The following are the basic steps I went through in order to succesfully integrate the receiver into the 7" monitor.
I also have a complete build log with pictures and documentation on my website:
The Haier 7" monitor when I received it in the mail. Very good quality considering it only cost me $40.
The monitor has AV inputs on the side of the screen as well as a coaxial input for the built in TV-tuner.
The pins holding the TV tuner down had to be cut and desoldered from the board in order to completely remove the TV tuner and make room for the 5.8GHz receiver.
All the pins succesfully removed and desoldered from the board.
This is what the PCB of the monitor looks like when the TV tuner is removed.
I removed the 5.8GHz receiver from the metal case that it came in and placed it on the PCB of the monitor. I tried my best to line it up with the hole in the side of the case that used to accomodate the TV tuner's coaxial input.
Soldered cables from a location on the monitor that was supplying 7.6V to the 5.8GHz receiver.
Soldered an audio and video cable from one of the receiver's outputs to the AV inputs of the monitor. Due to the fact that I had soldered them from the inside, the AV terminals essentially became AV outputs and I was able to plug in goggles into the terminals so that a second person can watch the FPV flight.
Secured the receiver to the PCB using several layers of double sided foam tape.
Screwed the case back together and it was all done! Very compact and extremely easy to use and setup at the field.
