I'm preparing to return to a pastime that I gave up a few years ago: flying radio-controlled model airplanes by first-person view, or FPV. Telemetry to Go: My ground station for receiving video was a battery-powered Raspberry Pi connected to two Wi-Fi dongles [top]. On board the plane, I mounted a camera module attached to a Pi Zero [bottom]. The final nail in the coffin was that I discovered that the Raspberry Pi Zero's camera connector wasn't making a very solid connection to its ribbon cable.
