It's done! The item retrieval system is finished. Inspired by a designs from youtube artists Ipismai and CobblestoneAndDirt . Make sure to check them out. I borrowed Cobble's one-wide timed loader design for the final product... I made several attempts at reproducing and enhancing their examples. The main goals became to reduce the overall footprint, make it scalable, and most of all practical to use in SMP.

I went through a couple iterations, each attempt running into problems with circuits cross talking and flaking out. Eventually it dawned on me to flip the whole thing around and tuck the mechanism underneath the sorting system. It just clicked from there, and I was able to improve the trigger circuits, compact the footprint to fit neatly under the BFMC Warehouse system (or any standard one at that!), and it will scale to any even numbered bay size (although it might not be practical). NextI really need to make a video explaining the system and fixes you must make due to how the schematics place tracks and droppers...

Let me know what you think.
