We developed a simple controller to pilot drones/cars/boats/etc. via 3G cellular connection, using a custom PCB on top of a Raspberry A+ with a camera.
Here is a video of test flight controlled via a 64Kbps cellular connection:
A view of the Raspberrry Pi "Hat":
All the source files, schematics and CAD files are open source and on github:
Any feedback would be welcome in order to guide the development of the project.
Anyone else interested in FPV control over cellular connection? If so, what setup are you now using?
