Quanum FPV All in one Goggles

by UltraSaucy | April 8, 2015 | (5) Posted in Projects

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:

quanum fpv goggles:

Boscam rx5808 video reciever

DC power converter

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:

  1. connect battery to the dc converter. use your multi meter to test the output voltage. turn the Potentiometer until the output is 5v
  2. 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)
  3. solder the pcb sma connector to the reciever
  4. connect the 5v and ground of the converter to the 5v in and ground on the reciever
  5. connect a wire from the recievers video out to one of the screens video inputs
  6. plug an antenna in
  7. turn on some sort of video source
  8. plug in battery and hope everything works
  9. if everything turns on and you have a picture on the monitor, unplug the battery
  10. now comes the fun part: shoving everything into the case
  11. first hot glue the dc converter inside the case (see pictures)
  12. next, figure out where the reciever will go and mark hole for antenna
  13. drill a hole big enough for the antenna to fit through
  14. pour hot glue on everything and close it up
  15. 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)

where the dc converter is mounted(top of screen)

where the antenna is mounted

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!

nice article! I made a little depron cover to put on the back of my quanum goggles and I somehow managed to get a rc832 receiver in there. works great but I did put a topstrap on the goggles so it wouldn't be that heavy on my head.

Going to have to do this, honestly. Awesome!

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?

Glad you liked it! you should post pictures when you are finished :D. Not sure about the rotary encoder, if I find anything like that I will be sure to let you know

Ah, easier than I thought. http://www.digikey.nl/product-detail/en/94HBB08T/GH7258-ND/726316 is one. The 94H series is all kinds of rotary dip switch. Should be an easy mount too, and they sell knobs that fit.

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

Thanks so much! This is an awesome mod. I just finished mine tonight. I added the channel selector switch I hot glued it inside the center hole and put the power wire out one of the bottom lower holes. I also have one external video in for a ground station since this only does 8 channels. And as a bonus the 4th switch I used to turn the internal module off to save power when hooked up to the ground station!! I never would have made it that far with out your article. Thanks again!!
