I have some understanding on what extender pistons do, hence the setup on the right, but zero idea HOW to make it work. I know they need sequenced signals to pull blocks two and four out of the way and then double extend to grab one and three, but that's like eight(?) total actions just to open the door when the other three sides only need the one signal. I'd love to be able to figure this out on my own, but my mind has never been very technically oriented. I would really appreciate suggestions on how to wire up that right side.
Also weird how limiting it is to power pistons from below.
