73. True Wireless camera setup

For this project, we are going to utilize the same transmitter and receiver method as in the long-previous project, but instead of a 2.4 GHz frequency, it utilizes a more common 5.8 GHz frequency. The reason why we would use a 5.8 GHz frequency instead of a 2.4 GHz frequency is that they are cheap to use, can be small for r/c aircraft/vehicles, and can transmit signals on a farther range.

For this particular project, we will be focusing on the receiver aspect, since it will use the TFT screen for better viewing as we control the robot. Not only that, installing the transmitter/camera on the vehicle is self-explanatory.  To start with, you will need a 5.8 GHz receiver that can output composite video, as well as an 11.1-volt power supply, like a lipo battery. As mentioned, you will need a 3.5" TFT screen for seeing the camera's view.

You will also need a custom housing to mount the screen, receiver, and battery in. That way, the parts will stay secure while having a nice appearance. It can be done with or without a 3d printer, but it's highly recommended to use the 3-d printer since you can make custom measurements so that the parts fit. When making the screen housing, make sure to add a roof on top so that the screen will be visible even when it was brought outside.

The wiring for this project is simple to do all you need to do is hook up the battery to the 5.8 GHz receiver (with the switch installed), and connect the TFT screen to the same power lines with the receiver. In the end, you will have a parallel circuit. To get the screen to display the FPV, you will need to hook up the receiver's video output to the TFT screen input. Double-check to make sure the screen works as you connect the video signal.

The 5.8 GHz receiver will have a way of finding the right signal manually, which is by looking up the actual Frequency, and the channels. There, you can press those 2 buttons to check the right signal the transmitter is generating. If you found the right channel/frequency, you will see a live feed of the camera view on the TFT screen.

Having FPV on your r/c vehicles will open up many possibilities, since seeing the view without looking up will allow you to control to greater distances.

Be warned that if you have a transmitter that is too powerful, you will need to have a license, or in other countries, it can get banned easily. But whatever the case might be, stay safe, and have fun.
