I designed this vending machine for a Vanilla SMP server to be as full-featured as possible, but as a result it also got quite large. As it stands it's 13x17x12 blocks. I'm hoping someone might be interested in helping me shave a block or two off the measurements.
I think the biggest space issue is the redstone wire runs up, down, and all over. Is there a way to replace some of the logic circuits to move the outputs around and reduce redstone wire? Can the clock circuits be consolidated? Is there a better way to handle the sellout protection?
Help?
