Introduction: FPV 7" Monitor DIY
Cost me $50 to build this First Person View for flying quad drones around at the park or at home. it is fun looking down at everything from the sky.
NOTE: if you need a camera to go with this, look up AIO (All In One) which means the cam comes with a mi
transmitter and antenna) cam or fpv cam, you'll have to read the band /frequency spec to link up your cam (transmit) and your reciever.
I posted links for all items required to make this work. I used my kids power wheels battery, and an old lithium ion battery 7.4v 1500mah. no c's or s's listed just straight volts works.
supplies: 7" monitor, fpv reciever, jst battery cable, (maybe an AIO cam) supplies: rca female-for vid2, jst connector-for alligator clips and for lipo/li-ion battery, fpv reciever, 7" monitor ( can be 5, 4 or 3") smaller gets cheaper. You can also apply this build to a fpv goggle set up.

you will need cut off the power connectors and introduce jst connectors. NOTE: I don't discuss camera/dvr. However, here are the links to where I got it from. try to order from us warehouse.
not the best camera in low light, BUT, it by far the most durable survivor of mega crashes

Step 1: Wiring Set Up
First of all, the plugs I used to make all connections came with the receiver and monitor. You will need an additional jst male for a battery that does not have one.
In the video you'll see that I mention, I will be connecting wires, removing wires and replacing or piggy backing wires. Also, I explain how I am setting them up.
1) I am piggy backing the female jst to the monitor's wire harness wires of red and black.
2) I connect the male jst to my alligator clips to use the power wheels 12v battery: red to + and black to -.
I am also adding a second jst male connector to my li-ion or lipo 7.4 1500mah battery.
3) I am connecting the RCA female to the monitor's vid 2.
4) I am soldering my receiver's harness wires directly to the back post of the monitor's wiring jacket where you see the cable wires plugged into at the lower mid section.
Step 2: Soldering Wires
1) I soldered the jst red and black wires to the monitor's harness' red and black, kind of a piggy back soldering.
As you are looking at the harness I soldered the jst wire underneath not at the top or the wires will not lock in or fit properly.
2) As you can see, I soldered my universal jst/aliclip cable for differing power sources.
3) My finger points to my soldering to the back of the jacket on the board where post 1 is red, post 2 is black and post 3 is yellow (video). Those three are connected to the receiver's harness.
I removed other wires I don't need from the harness.
Step 3: Attaching and Protect Wire Ends
I am taping up the tip of extra wires and exposed wires.
2) I have trimmed the RCA jack to fit tightly between the two posts (don't need screws) and between the monitor cover.
3) looking at the monitors wiring harness: I connected the vid 2 RCA jack to no.4 and 5 which is going to be black then white. Remove the green, you don't need it.
3.a) I soldered the RCA jacks to the monitor's harness 4 black and 5 white.
Step 4: Measuring to Cut Case Fitting
1) I cut a slit at the bottom of the back cover, just enough to ensure it sits inside the that groove on the RCA jack.
This is to make sure the RCA jack doesn't move at all when plugging in external vid 2.
2) I drilled a hole at the top to fit the antenna jack of the receiver.
2a) I am using the RCA plugs v/a on the receiver only for my mini dvr. You can connect an external video source if you want. This allows another monitor to view, possibly if your viewing from dvd.
3) as you notice where the receiver is going to mount, I removed a bottom nub of the three so the receiver can sit perfectly.
4) finally, the power jst wires is running out of the monitor from the left side rectangular hole that is already there.
Note: you will want to mount your wire inside the monitor housing so if something pulls the power wire it doesn't stress the solder points.
Step 5: Check Mountings, Wires N Test
1) I heated a strip of plastic to wrap the receiver and used the two screw mounts on the side to mount the receiver.
2) some batteries come with the red jst plug mostly the 7.4v.
3) Running in vid 1 you can see video feed from the wireless fpv cam.
4) Notice that the monitor has buttons to switch from vid 1 to vid 2 and on/off which I demonstrated. No need to add extra switches.
