How can i measure the RPM of our shooter CIM if the CIM is not connected to a gearbox.
Many teams make their own home-brew one-count-per-rev optical or magnetic sensor. A sensor like that is excellent for shooter wheel speeds, if decoded properly.

Optical: Paint half the wheel white and the other half black, and sense it with a photosensor.

Magnetic: put a pair of magnets on the wheel, 180 degrees apart, and sense it with a latching Hall sensor (US1881 works well)

There are many other configurations.
