About this video

So, I have been trying to noodle this out for a while and the only videos I could find on using logic gates was their basic use or how to make a two way switched door.
I wanted a setup that would allow me to just pull x number of x components into any given builder (50 each lets say)
Then for the builder to press out what ever it can of item X on what it got.
Then when the builder stops producing item X the vacuum hopper will power on and put all the extra back into inventory.
