Three addtional redstone designs using the 1.21 snapshot crafter

Turns out the "complex" design also works for dispensors. Just have the non-stackable go in first (for what would now be the empty slot). Some trickery around extending the duration of the clock to allow all the items from the hoppers to filter through, but not enough different to justify recording another video. Basically have the "on pulse" also trigger a fader circuit to hold the clock off instead of coming back directly via a repeater. In terms of being able to feed items into the droppers, can always put solid blocks with redstone on them over the solid blocks, between the droppers and the comparitors, this allows the droppers to feed into the side of the hopper hopper line to the crafter and allows hoppers to feed into the top of the droppers.
