 Timed fades circuit for stage lighting desk I’m building a stage lighting desk for an amateur dramatics group and need a timed fade-up and timed fade-down circuit to achieve the following: -adjustable timed fade up from 0 to 10v over 0 to 10 minutes, initiated by rapid fade up of a slider pot -adjustable timed fade down from 10 to 0v over 0 to 10 minutes, initiated by rapid fade down of a slider pot Can anyone help please? | |

| This circuit should work. When the slider is at the center, the time is very long, it may be dificult to determing a setting for 10 minutes. zero to 10 minutes is an infinite ratio, so that is not possible. The minimum time is about 50 milliseconds.
