How it works is the feedtape cycles the observer and when it activates that front piston, it pushes a blue glass block up. There are 11 blue glass blocks, the stone block which is already being pushed by the back piston, and the redstone block. So when the redstone block reaches the back it fills up the push limit for that back piston, stopping the whole machine. It also activates the 2 pistons next to it which push the observer clocks into place that dispense tnt. My problem with it is that it can only travel about 288 blocks, since it cycles a blue glass block every 24 blocks or so. 288 blocks isn’t very practical for a bomber like this. If you know any way I can increase the range without having to manually reset it let me know.
Also I know the screen looks goofy because I’m on bedrock and my friend put that stupid money display on the side and I can’t get rid of it lol.
