Remember the MITAC Gyroscope? Well perhaps I'm showing my age. It was a classic back in the 60's. Our gyroscope is very similar but is updated with modern slip rings and a stepper motor to give precise rotational speed to the rotor. The apparatus is large enough to observe from the farthest seats in your classroom with the rotor some 8 inches in diameter and the outer gimball over 12" in diameter. Custom made on request.
