Welcome to another unnecessary build idea from the mind of this guy punching the keyboard right now. <3. Today my silly idea is to make a kelp cooking station from wet ocean picked soggy green kelp to firm cooked and compacted delicious kelp by the bundle.
As is per my usual I try to make my builds small so you spend all day looking around the base to find where the heck this is. lol - good fun...

This is a 1 block wide build, for the most part. Furnace at the top with hopper pulling cooked product from below and putting it into a dropper. The dropper is facing downward so as to place an item into the crafting block below it. The crafting block is facing downward so as to place an item in the barrel below it.
The comparator on the oak block is checking the dropper for an item and the observer will see the comparator change state sending power to the dropper. The dropper will place a single item into each slot of the crafting blocks grid one at a time until the crafting grid is full. Hoppers will fill the first slot to max stack before putting into the next slot. This is why I am sending items into dropper.
The comparator after the oak block is checking to see when the crafting block has a recipe ready to make. This build wants all 9 slots in the grid filled before sending power. To compare this I needed to set the lower comparator to subtract and add a couple blocks to set the power right.

It pains me to have these blocks sticking out like a broken leg but there it is.
A full composter with this setup lets the subtracting comparator trigger once the crafting block recipe is ready. Take notice that under the subtracting comparator is an observer that is facing upward and triggers when the comparator does. Then another observer sends that signal to the barrel which powers the crafter. *(sending full power into a solid block will power another block connected the the first one) I love that a barrel can transfer redstone power as well as be a storage block.
This does not work when the furnace produces more than 1 item at a time such like ores on Foxcraft and so I have dubbed this one a kitchen Kelper.
The build is very sleek and fits into many build ideas, I had several but suffice it to show the bare build.
Hope you have a great day, have fun out there.
