I am trying to create a remote for my shades. My shades are top down\bottom up, meaning there is a cord on each side (one raises the bottom, the other raises the top). Currently you need to pull the string to the side to unlock the string, then pull up and down like a regular shade.
My plan was to break the locking mechanism so that if you pull the string, the shade goes up (or down) and you need to hold it. I need a pulley and motor so that when it is at the proper setting, the pulley would stop and be able to hold without power.
If I could find a motor like that, I would simply have to go in one direction to pull up, in the other direction to go down, then stop when at the right height. I can’t supply tension using the motor since most of the time it will be off.
I also need something that is somewhat small so that it can be mounted below the window. I will probably need two for each shade, one for the top and one for the bottom. I will also need a set of these for each of my 4 shades. I have seen small motors, but nothing that will suite my needs.
