Hello, I'm sorta new to the drone building world and I'm fairly confident that with enough research and learning, I'd be able to build my custom quadcopter. I wanted to look into this "is it possible" question before I get really invested though. For this build, I want to make my own remote controller for the drone to make the drone (which will also be custom) do some fancier things, like a button to deploy emergency parachutes, a button to allow smaller drones to be housed on a deck that will lie across the top of the drone, etc. I believe that a pair of arduinos with the right transceivers could accomplish 100% of the additional stuff I want to outfit my drone with.
For those special features, I plan to use a basic remote controller that transmits and receives the basic stuff (like up/down/left/right/forward/backward as well as the battery status and whatnot) and then build around it with the additional stuff. I also plan to have an video feed to the FPV camera on the drone on the top of the controller so that I can still see if the drone gets out of sight. The last thing I am going to have is a raspberry pi on both the drone and the controller that will be sending data between each other.
With all of this in mind..... I need to figure out how to keep these signals from interfering with each other. Forget battery load, physical weight, and other stuff you might find flaw in with this monstrosity of a design. From what I've researched so far, the video signal for the camera should be on a 5.8 GHZ channel and everything else should be on a 2.4 GHZ signal.
The problem is that I potentially have 3 2.4 GHZ signals with the communications happening for the Raspberry pi's, the arduinos, and the regular radio input/output signals for the regular quadcopter stuff. I considered making the flight controller from an arduino and essentially combining 2 of those signals into 1 signal but upon looking it up, it looks like a very messy thing to try to pull off even for veteran drone builders. So what I essentially need is a way to have those 4 signals (video signal, arduino signal, drone movement/battery signal, and raspberry pi signal) coexist sending and receiving data to and from the controller and the drone. Is there a way to set all of these devices up so that they do not cause interference with each other? Is the solution to this problem as simple as soldering a wire from the 2.4 GHZ transmitter to all 3 of the devices that need it? Because I REALLY don't feel like spending hundreds of dollars and tons of time on this drone to have it not lift off or fall straight out of the sky due to signal interference.
Any/all help would be greatly appreciated. Thank you very much!
