This design is way simpler than the first version and it only uses 1 observer block
•Repeater should be on 2 ticks
•Observer Block's face should face up
You can remove the bottom set os piston and it will work the same.
But you cant remove the top set of pistons.
Check out my account for other double piston extender designs:
YAY that's awesome Thanks!
i think ill be able to put 2 of those side by side and connect with just 1 lever so i can make a great door.
maybe 3 or 4 high would be my next idea
