1) Absolutely gorgeous! 2) that satisfying snap when it locks into place - great attention on the detent! 3) Awesome production value on the instructable.
I'd sure love to see a video! I'm in the process of a similar project, but the issue I'm finding is that the 1:48 gear ratio is still much too tall. When driven hard enough to have the necessary torque, the blinds move way too fast (and precisely stopping at full-open is hard). I've found those cheap stepper motors seem to work very well, but I'd love not to have 6 wires per window.

How on earth did you find the TIME for this?! And the space before and after deployment? I'm just so shocked by the immensity of the build.
Well, two things, I guess: space, and the freedom to hang a giant friggin' pirate ship in it :)
Clever and simple, I like it!But you definitely shouldn't use this in any practical application. As others mention, it's got some limitations. The most important one, as far as I'm concerned, is that the relay will only last about 30 minutes before falling apart, and when it does, it'll likely fail in such a way that the transformer sees only DC from a very high power source, likely resulting in wires catching fire. Relays are typically rated for 100,000 actuations, which get used up pretty quickly when you switch at 60Hz.
Looks great, good work!
