I am looking to make a pillar that rises out of the ground and then lowers back down. To do this I need a single column piston lift that operates like the one in this video from the tutorial (). What I cannot figure out is the schematic that brings the sticky pistons back down and the video does not do a very good job of showing that particular aspect. Pistons seem to stick to opaque blocks when they are activated, so they do not naturally fall or stay stuck to the lower piston. This schematic seems to be able to unhook each piston and have the lower one retrieve it.
Can anyone break it down for me as to how this works? I can see the redstone torches flickering sending a signal up (I think), but I cannot seem to replicate it.
I would not personally use this design, I would go for a much simpler elevator. If you make a minecart elevator it will be less painful and time consuming to build. They are the fastest type of elevator too. Heres A video Link:
I have one in my world out of my slime farm. Works great.
A single column sand/gravel elevator would be much more efficient... but there are much faster ways to go up/down if you want efficiency.
(Here's an example):
Sticky pistons stick to individual blocks without meta data, and only when retracting, this means that you cannot push/pull an extended (sticky) piston (due to being 2 blocks in size, or furnaces, chests, MOB spawners, crafting tables, enchanting tables, etc. due to having meta data) and when a collapsed sticky piston is pulled back by another sticky piston, the first does not stick to any blocks connecting to the sticky face because that piston is not actively collapsing.
This unfortunately makes the redstone logic particularly complex, this video uses levers to (manually) show how the redstone circuit logic has to be delivered in order to make this work:
...getting the redstone logic to do this automatically (not manually by levers) requires some ingenuity....

Right, which is what it looks like the cat in the video I linked to has done. When the pillar retracts, the redstone torches flicker off in sequence to do what this guy is doing with levers. What I have to figure out is what that logic routine is.
I don't think the sand elevator will work as I need to be able to raise and lower the my stone brick pillar up out of the ground and then back down into it in two fluid motions. (i.e. step on panel, pillar rises, step off panel, pillar descends). Which is why the routine in your second video looks like what I need, only vertical and sans levers.
Now that you have shared that second video, I think I can take a better crack at it. Thank you the logic is clearer now!
How do you plan on making your stone brick pillar retract beyond the stone that attaches directly to the sticky piston? Remember that they aren't connected/stuck to each other for retraction purposes.

Obviously you will not be able to use the sand elevator if you use other blocks other than sand. I assume that your stone brick pillar is really just one block with pistons underneath it? This certainly is not the fastest elevator, but it is likely the only piston elevator at the moment that has the best chance to work in MCXBox multiplayer. The piston timings could still cause the elevator to fail in multiplayer games, especially as you add more pistons and if you try to increase the speed. Check out this short tutorial showing you how to set up this elevator:
Good luck.

And that's where the whole bloody plan falls apart isn't it. Ah well, it was interesting while it lived in my brain. Still, I learned a lot about redstone and pistons, so the exercise was not a complete loss.
Thanks for all the tips and tricks!

Edited to fix the broken link.
