Step 1: Connecting the Transmitter
There are two options you can do to connect the wires attached to the camera to the transmitter. The first way is to solder. To do this you will need two people. The first thing to do will be to strip off the outside of all the ends of the wires just a little bit so the actual wire is showing. One thing to remember is that the colors of the wire are going to match. There are three colors on both connectors. For example the red wires connected to the camera and transmitter will go together. You will solder one pair at a time. Before you start soldering make sure to put some heat shrink on one piece of each color. One person will hold the two matching color wires perpendicular right above each other. The other person will take the soldering iron and put it on one side of the wires and the solder on the other. Once the wires are soldered together, slip the heat shrink over where they pieces were soldered. Then use a heat gun to shrink it around the wire. The other way to attach the wires will be to crimp. We had to do this because the solder wasn’t working. After either way you should check that the continuity is working. This may be a slightly more difficult process but it will make the connection stronger. Like in the other way the first thing that needs to happen is the ends of all wires need to be stripped. The next step is to take a male connector pin and place it in the crimp. After this close it but not completely so that the wire can go in the pin. Then you can close it. After completing this for all six wires put them into pwm cables. Keep in mind that the colors of the wire have to connect together so maybe the yellow wires both go on the left.
Step 2: Making the Camera Stand
The first step will be to take measurements of your camera. You will only need to take measurements of one camera. There will be two parts for the stand. The first will be the base which will be flat on the car. To take measurements you will need an Electronic Digital Caliper. For the base take measurements of the length. Take all of the measurements in mm because the website you will be using uses mm. You will be making both pieces on a website called tinkercad. Start out by placing a box in the square. For the length double it from the measurement and add a few more inches because there are two cameras. For the height make it 5 mm. For the width make it 20mm. To print to to edit and click download and save it as an stl then open it in makerbot to print. After you print that piece it will be time to make the actual stand. Once again start with a box. For the measurements take the width. Enter the height as mm. The length should be the same as the last time including when it was doubled. Then enter the width. Repeat the past steps to print this piece. After it will be time to hot glue. First glue the base onto the front of the car so the cameras will have a good view. After glue the cameras on the edge. Then glue the stand so that the cameras are leaning up against it. Make sure the cameras are facing upright. If you are unsure test it and glue it on later after the 3d goggles and receivers work.
Step 3: Putting Things in the Car
To put the batteries in the car use zipties to hold them together. For the two transmitters you will need cloth to go under them because otherwise it will melt the car, so the cloth can be attached to the transmitters with a ziptie. It is also important to make sure the fan is not covered. After the transmitters are on the car, screw the antennas on the transmitters. It will screw on the gold part of the transmitter. The red connectors attached to the transmitters will go with the red connectors on the tenergy 7.4v 2200mah high power lipo pack batteries. You may also need another one of those batteries for the car itself.
Step 4: Connecting Receiver
The first thing you need to do in order to connect your receiver is get the 2 RC832 fpv receivers and Turnigy 1000mAh 2S 20C Lipo Pack. Next, connect antennas to both receivers. Next, connect the RC832 fpv receivers to your goggles. To do this connect your RCA cables into the AV OUT1 and the DC 12V inputs. Make sure that the wires with the white, yellow, and red is connected to the AV OUT1 and the other cable with the red end is connected to the other. This way, both transmitters connect through the white, yellow, red cords, and they connect straight to the goggles in the side of the VR Camera. There will be red cords sticking out which can connect to the transmitters both and the battery pack. Insert both yellow cords into the side of the camera and the red cords to red. There will be a lot of wiring so use velcro straps to neaten it up.
Step 5: 3d Googles
Directions to wiring in the camera are explained in the last step and the picture below. A good way to set the camera to be more comfortable on your face is to use double-sided sticky tape on the outside lens part of the camera, then cut off pieces of a pipe insulation foam piece to stick on. This will make the camera more comfortable and reasonable to work with, with some more velcro strapping for the wires. When you connect the camera for the first time, it usually will not be on the correct channel at first. To find the channel, use the button on the Receiver that says CH and FR. There are many channels, so it might take a while to find on both receivers.
