(this is my first post so idk how to place pictures.)
So yea, this is it.
I dont even know what to say tbh, just look at the picture.
When its off, the item would be at the first dropper. When it is turned on, it will trow the item into the hopper, that will send it
to the second hopper, that will send it to the second dropper. Because there is an item there, it will power the comparator.
When it is turned off, the repeater will power the second dropper, sending it to the first, stopping the comparator from sending signal.
Turning it on has a slight delay, that depends on the duration of the signal. Because of the repeater, it will also power the hopper above it,
so the item wont go to the second dropper untill the signal stops. If you wanna, you can place a comparator in the first dropper, or placing a signal shortener before.
I searched the Minecraft Wiki and there isnt a similar model, if there is one similar out there tell me.
I call it 2H2D, that means 2 Hoppers 2 Droppers, and that is pretty much it.
So, what yours think about it?
