[SML] Cheapie DC motor controlled by PWM?

[Nigel Worsley]

Take a look at continuous rotation servos, physically they are the
same as RC servos but the control input tells them to drive forwards
or backwards at a variable speed instead of going to a specific
position. There are plenty of DMX to servo interfaces available that
will let you hook it all up to the lighting console for control.
