Hello you guys,
I have this wheel (flywheel on a RC gas engine) and I want to measure the RPM's.
I have paintet the flywheel black, and put a bit of white paint on one spot on the wheel. See the drawing.
Now, my problem is, what kind of optical component could be used to sense if the black or white color is in front of the sensor?
I thought about drilling a hole (or 2 to balance it) in the flywheel (to use an optical interrupt switch), but it's hardened steel, and it won't give in for the drill bit.
Any suggestions?
Regards,
Futterama
