    Didn't read the whold thing but it you want it all underground 100% you have to use sand so that the top block will fall back down.

    Simple put two pistons with two sand above them, set them up so the bottom one will activate first and deactivate last with an abba switch (I never figured those out...) and you have basically what you are asking for.

    (Or gravel.)


    Well, obviously. But I'm trying to use non-gravity affected blocks. I could easily just strap a double piston extender onto a pair of sand blocks, but sand/gravel doesn't fit with my color scheme. Thanks for the suggestion though.

    Theoretically, you could push the blocks of the wall up with sand, store them somehow, and then have the sand fall back down. Not too difficult.

    Don't beg for comments. People will reply if they have something to say. Don't sound desperate.

    Yeah, you need more angles. Not to mention, that way of making a piston door is extremely inefficient. Better designs are easy to find. You should make one of those.

    EDIT:
    Hmm... interesting. I know what causes it. Due to your timing, upon firing, the misfiring piston gets BUD'ed, and when the repeater for the 2x2 set of pistons fire, it fires the bottom pistons of that set before the top row of pistons. This may be a hashset error, not completely sure. That bottom piston firing updates the BUD piston before the top row of pistons push it out. An ABBA switch should fix this though.

    Make a toggleable clock attached to a dispenser. You can get up to a 0.5 tick arrow interval if you use the dispenser update bug.

    P.S. I have a $300 laptop that runs MC fine, so you don't need a good one at all.

    A T Flip Flop switches outputs when the button is pressed, so just have 1 output activate A and then B, and have output 2 activate B and then A.

    posted a message on BUD switch multiple repeaters, weird behavior
    I know the mechanic behind this, but it's a little lengthy, so bare with me for a bit. A BUD switch, by definition needs a block update to push the piston forward, and then another block update (also with the power to the piston off), to retract the piston. In the first design, you update the piston, removing power from the repeater. Now, the repeater and the redstone wire update at the same time, causing the retraction. I'll explain this better. A piston can receive a block update through the piston base, but ALSO through the piston arm. When the repeater goes off, it also updates the piston arm, causing a block update, retracting the piston.

    HOWEVER, on the 2nd design, the 2nd repeater adds something significant. When you update the piston, yes, the piston extends, cutting off power. However, when the 4 tick repeater turns off, the 1 tick repeater is still on, continuing the power to the BUD piston. Only after 1 tick (because repeaters delay a signal turning off as well as turning on), does the repeater cut off the power. However, after cutting off the power, the first 4 tick repeater has already been turned off, and it will not cause a block update to the arm of the piston, so, it effectively only receives 1 block update, from your initial block update.

    You, sir, have discovered the difference between a T-BUD and a BUD Switch. If you're still confused, don't hesitate to ask me.

    That awkward moment with redstone when someone asks you to make something, you tell them it'll be done in 10 minutes, and you take 10 hours.

    Nope. 1.5 ticks to extend, instant retract in 1.2.5. The reason B didn't extend for 2 ticks is probably due to the fact that you probably didn't delay it by 1.5 ticks, you delayed it by 2 ticks. In 1.3, it's 2 ticks to extend, but still instant retract, so then B could extend after 2 ticks.

    I like how all his facts were wrong.
