FPV Ground Station

Next Task: Waiting on paper design

For this project, I’m building an FPV ground station that can be used with my racing quad. This ground station will allow me to transport equipment and have a base of operations with an incorporated raspberry Pi for telemetry and other functions. In addition, it will allow me to show passers-by what I’m doing thanks to the large LCD screen, which can be used  to display my FPV downstream or my Pi desktop.

Planing

I don’t have a set deadline for this project, so I will have the ability to take my time and ensure everything is working perfectly and that the final product looks good. I don’t want the total cost of this project to be too high, the most expensive components will be the LCD, Driver and 5.8ghz receiver. Taking this into account I don’t want to spend more than £50 on this project. Once I have the funds set aside for this project, I shall order all the necessary components from various sources and supplier, once they arrive I shall begin the finalising the design and the build process.
