I took some pictures of the part to be rotated, found at the links below. It will also be a bit less complex, a better starting point. This will drastically reduce the amount of force needed, enabling me (I hope) to use a Servo instead of fooling with a DC motor. Instead of actually pulling the blinds up and down, I'm going to just tweak the little rotating spindle that opens and closes them. Update 4/2/13: I'm modifying the project objective slightly. Maybe someone with more servo experience could tell me what to expect? Will the servo continue to weaken over time or will it reach a plateau? So in the long-term, it looks like I'll need a more durable solution-unless this is just a breaking-in period for the servo. I tell it to turn for 15 seconds and during those 15 seconds it doesn't open or close the blinds as much as it did a few weeks ago. The only problem left to fix seems to be that the servo seems to be weakening over time. This was an easy fix I printed one with a thicker triangular rod. The Servo Mount I originally printed wasn't sturdy enough-the triangular rod that's perpendicular to the wall (out of which emerge the two circular rods that allow the servo to be mounted) broke off.(BTW, the Arduino enclosure is attached to the wall with just one of these picture hanging strips and that seems to work just fine.).I solved this by printing the blue Servo Mount and putting TWO strips on the back of it. This didn't provide enough support for long and the servo would sometimes peel off the wall as it tried to open the blinds. At first I just stuck a "Picture Hanging Strip" right on the servo.One mounts the servo to the wall next to the window (with the help of some "Picture Hanging Strips" from Home Depot) and one connects the servo arm to the blinds rod. The blue parts I had to print from my university's 3D printer, which is a MakerBot Replicator 2, I believe.
