Optical sensor

Post by Shaggy1505 » Sat Dec 30, 2017 10:15 pm

Hi, I am looking at designing a piece of equipment that will reduce the vibration in a small scale RC Helicopter. For this I am looking to measure the phase of the helicopter and the dc motor I will be using as the shaker. To then ensure the motor is 180 degrees out of phase with the helicopter. The question I have is how will I design a circuit to utilise an optical sensor to collect phase information of the helicopter and then the dc motor? Thank you in advance for your input

An interesting question for the end of the year. You don't give much idea of what space there is on the helicopter, but if you can fit everything in I expect the easiest thing to do would be to use a couple of reflective opto-sensors. Have one looking at the shaft of the blades, and the other at the motor. Tie it all together with software in a raspberry pi or similar. Search Google for optical sensors.
