| Basically if you can get it to look like the rotor blades are still through the wheel, you can then compute the rotor head RPMs based on your tach's motor speed (estimated by differentiating the position signal from the led). The relation will depend on how you make that wheel. # of rotor blades won't matter. You're trying to freeze the picture by sync'ing your wheel's "shutter" with the blades. |
