A single, variable speed stepper motor is used to rotate two B size gobos. Always rotating in opposition, the movement can be as slow as 0.5rpm for building subtle, naturalistic effects. The maximum speed of 24rpm is perfect for creating a raging inferno or wild kinetic effects. SimpleSpin is primarily a manual control, "set and forget" device. Define the perfect look for your lighting effect by precisely trimming the speed control knob and then simply power the speed control knob and them simply power the SimpleSpin up and down from the mains. Where varying speed control is needed, SimpleSpin can be plugged into a dimmer and controlled by a lighting desk. Configured this way, the speed of rotation will increase or decrease as the level on the dimmer goes up or down. Using a stepper motor and thoughtfully engineered control circuitry avoids one of the most common complaits lodged against budget rotators - low speed stalls and insufficient torque. Specifications:
