Hi everyone, I am building a FPV (first person view) to place into an other project (a rc plane). I am looking for a gyro that would attach to my video goggles, so that when I pan my head left or right it would move my camera left or right. The same for up and down. I am planing on useing a 2 channel futaba radio to send out a single to my recievers/servos that are hooked to my camera. I guess what I am looking for is a gyro that I can directly hook up to the potentiometers in the transmitter at the control sticks to send a signal or a gyro that hooks up to servos(2) that is mechanically hooked up to the potentiometers in the transmitter. Please forgive me if this is in the wrong forum, I am new here. I know there are a lot of smart ppl in here and I hope you take the time to help me out.
Thank you

ps. lol yes I know I can buy one, but…there is something about building it yourself and saying I did that!
Welcome to the RobotShop forum. You have certainly come to the right place. Your project is entirely feasible, but some of the details need to be clarified: from what we understand, you want to use a gyro to control a pan/tilt system wirelessly using a 2ch Futaba R/C system. First, you should be considering an IMU (inertia measurement unit) rather than just a gyroscope as it helps compensate for drift. This means you will have to manage the output from two gyroscopes and three accelerometers (your R/C control only uses two analog inputs with unknown specifications).
The easiest approach is to use a microcontroller such as the Arduino Nano or Diecimilla as intermediary – you would program it to calculate the angles based on the inputs and then output an analog voltage from one its A/D pins. You would need to use a multi-meter to determine the output of the Futaba controls before you “hack” it. This will enable you to devise code that makes the output proportional to the head movement. Note as well that an IMU can do complete 360 degree motion, whereas the joystick on a Futaba remote is limited. You will need to account for this somehow or else your camera position will be inaccurate very fast.
