Controlling A Block Camera With An RC Transmitter

The world of drones and FPV remote-controlled aircraft is rapidly expanding, airframes are getting bigger, and the demand for even cooler AV gear is higher than ever. [elad] got his hands on a Sony block camera that is able to zoom in on a scene – great if you want to get close to the action while still flying a safe distance away. Controlling the zoom on these cameras is usually done through RS232, but [elad] made it work with an RC transmitter.

The camera [elad] is using is a Sony FCB-EX11D block camera with a standard SD resolution sensor. This camera has 10x optical zoom, making it a great solution to aerial surveillance, the only problem being the RS232 connection and the VISCA protocol. [elad] used an Arduino to listen in on the elevator channel from an RC receiver, translating that to something the camera will understand. The result is a controllable zoom on a camera that could easily take to the skies.

The entire camera package, with Arduino and electronics included, weighs in at about 100 grams. That’s about the same as a GoPro, and would fit perfectly on a camera gimbal. The only problem is getting a transmitter with enough channels or someone else to operate the camera while flying. Video below.

        1. it was just for testing later i switched it to elev channel
          which doesnt make any difference since anyhow you’ll need
          to calibrate it to your remote in case you dont use the same equipment
          but if you use the same equipment then you should connect it to elev ch
