Hello. I've been working on a stacked vertical piston switcher for a bubble column where the lower set of pistons are extended by default, and pressing a button reverses the pistons for a period of time (timing mechanism I'll implement later). I've wired one side, shown below:
What annoys me is how blown-up my design is. Placing redstone torches directly behind one piston activates that one and whatever's above or below it. Are there any ways to improve my design, or does there exist a better one?
One thing to note, I do want to add the ability to temporarily retract both sets of pistons (i.e., to reveal a hidden area below the bubble column)
