You need a microcontroller and MIKEMI's motor reversing circuit with limit switches. Search his recent posts or look for the motor reversing threads. You might substitute the CD4060 for the microcontroller. Good luck!

Do you already have a motorized drive for the blinds?

If so, what voltage does it run on? You might as well incorporate the timer into the drive.

What is the 1 minute period? Is that how long the motor must run for the blinds to completely open or close?

Does the blind actuator have its own limit switches? i.e. does it stop moving when the blinds reach the fully open/full closed position?
