I’ve had a few people ask me to clarify where the servo actually goes. And as I stated before I planned to do a full, start to finish video tutorial. I still will, but I lied on the timeline. It’s summer, I’m a home owner with many things to do, and I’m a beer drinker with many women to slur at. This blog will be more lively in the winter.
Anyway this blog post with be a live document where I will continue to add more how-to details on the blinds project. I’ve decided to start a new post because my original one was getting very long.
Tutorial #1 – Where does the servo go?
Taken from a photo that a viewer sent me, I’ve updated it with the latest in computer graphics to demonstrate that in my case I had to remove the manual crank, shorten the rod (mine was plastic) and hot glue the servo into one of the spools.
My question/advice was to see if you can turn the rod, by hand, with the manual crank still in place. Is there resistance? If so that means the crank needs to be removed. It’s pretty easy; in my case it’s just held in by clips. Looks the same in this guy’s case too.
One issue with this guy’s set up is where the green arrow is pointing, you can see that the rod is what rests on the brackets/holders. But in my set up, the spool (metal drum.. plastic in my case) has a lip on each end and this is what rests on the holders. So, this guy will have to be innovative to get this to work and I look forward to seeing photos of how it’s accomplished.
p.s. I’ve been super negligent in my task of offering a tutorial of this. I just haven’t built anymore yet.
Home Awesomation 
Yup I removed and the rod spins freely. But as I mentioned my rod is square so how would I glue it where the silver thing is. If I remove that it is just hollow with just the rod. See how I pushed the servo in the manual crank. I did that because the space that is left I can just fill with hot glue and it will make them touch, but since the rod is square, it makes this project a lot harder, or maybe impossible with a square rod.
I dont think that the rod being square matters at all. Mine was a hexagon. Remove the manual crank box. Slide the rod back, so that it is only half way through the silver spool. Stick the servo into the square hole in the silver spool. Bond the servo spline to the square hole with hot glue.
My real concern is the last paragraph in my post.
