I am trying to get two pistons to synch their pulses for an item sorter (nether).
In the attached pic:
- Observer which has a string in front of it (far side) that sees items drop down out of a cobweb, it pulses the redstone to start the pistons
- The primary piston (#2) that pushes the items a block over towards the secondary piston (#3)
- The Secondary piston (#3) that pushes the items along the ice path.
The redstone and repeaters are currently set up so that the observer pulse pushes the primary piston first, then after a short delay pushes the secondary piston.
What I am trying to do is prevent the primary piston from extending while the secondary is active. What's happening is every now and again due to timing of items dropping past the string, the secondary piston is extended and the primary piston pulses pushing items onto the top of the extended slime block attached to the secondary piston, vs. those items dropping into the empty space while it's withdrawn.
Any help appreciated!
I am by no means good at redstone, so I do not know if my solution is compact or efficient (or any good at all!).
My approach is to make the pistons fire alternatively constantly until the string is not triggered for a few seconds then it stops firing the pistons. This way there is always a constant piston firing rate and after the last item has fallen through the string the pistons still fire a couple of times just in case some items fell on top of a slime block then this will clear the items.
In the images you can see I made a pulse extender coming off the observer that is looking at the string. Then there are observers looking at the dust that is part of the pulse extender and every time the pulse degrades the observers trigger. Then after those observers are repeaters to slightly extend the pulse so that the pistons fire slow enough not to leave their slime blocks behind.
Note that the repeater after the left observer is 3 ticks and the repeater after the right observer is 4 ticks.
that's a novel approach, thanks for this - I am going to test it alongside my current version based off @authorinthedark@lemmy.sdf.org 's suggestion. Will come back with findings, thanks!
