After seeing flitetests most recent video about fpv boxes, I figured I may as well upload some pictures on one of my most recent fpv projects. Basically, I took the Quanum DIY FPV goggles from hobbyking and integrated a 5.8 FPV reciever into the screen. This allows the goggles to be extremely light and not need any cables (unless you hold the battery in your pocket. I didnt take many pictures of the build process, but I will do my best to show what I did so you can replicate it if you so choose.
NOTE: make sure your transmitter can transmit on the correct bands for the reciever
Parts needed:

rp-sma(or sma depending on what you use) female pcb adapter

some sort of battery connector(you problably already have these)
also useful but not needed:
right angle rp-sma(or sma) adapter(just do a quick ebay search)
Tools Needed:
Soldering iron
Drill
hot glue gun
Volt meter/multi meter
Steps:
- connect battery to the dc converter. use your multi meter to test the output voltage. turn the Potentiometer until the output is 5v
- connect battery lead to dc converter, as well as the screen voltage input(red wire) connect ground as well (black wire)(you may want to plug in a battery(2s or 3s) and make sure the screen and converter are working)
- solder the pcb sma connector to the reciever
- connect the 5v and ground of the converter to the 5v in and ground on the reciever
- connect a wire from the recievers video out to one of the screens video inputs
- plug an antenna in
- turn on some sort of video source
- plug in battery and hope everything works
- if everything turns on and you have a picture on the monitor, unplug the battery
- now comes the fun part: shoving everything into the case
- first hot glue the dc converter inside the case (see pictures)
- next, figure out where the reciever will go and mark hole for antenna
- drill a hole big enough for the antenna to fit through
- pour hot glue on everything and close it up
- enjoy!
back view(note the battery connecor and placement of reciever/antenna)side view (reciever adds no extra depth)
it works!(being powered from a 3s lipo)

another shot of the back without antenna
Note:you can use a 2cell or 3cell battery to power it
future upgrades/mods
add a dip switch to change channels
add a power switch to turn of reciever
add a video in lead to plug in external reciever
I hope somebody can benefit from this, and maybe even make one! If you have any questions just ask in the comments. Thanks for looking!

I've spent some time looking for an 8-position indexed rotary encoder with three outputs (well, six), or a rotary dip switch. So far, no good. It would make channel selection a snap, and better than regular dip switches. Anyone have any leads?

Too bad shipping to the Netherlands is prohibitive. Odd that I can't find a dirt cheap resource on something so useful.
