10C10.50 - Vectron
Seel also 6J11.31 in Optics.
This device shows several high tech principles. The first of these is rotational stability. As you can see in the movie when the device is started it spins. The spin gives it a very stable flight.
To allow the ring to move left or right or back and forth very fine control of the motors is required. The control console is used as the point of reference. If we want the ring to go to the right then every motor that spins around to the right side of the ring must slow slightly relative to the other motors.
Another high tech part of this device is the LED advertising billboard. Basically there is a single strip of LED that is flashed at the appropriate time when the ring is spinning. This flashing combined with the eyes' persistence of vision allows you to see words.
The Vectron Ultralite is a version of the original Vectron that is much simpler to use. There is no tether and no lateral control, only controls for up and down. The toy will move according to the currents in the lecture room.
NOTE: Works best in a room with flat ceilings no higher than ten foot.
The vectron can be also used for the Skywriter demonstration 6J11.31.
