Complex storage safe edu project

This is an educational project designed to show how some redstone devices work in relation to eachother, the building is a nearly inpenatrable combanation lock storage facility, THE CURRENT COMBO IS 1234.

inside there are detailed instructions for reseting the combanation lock using a system of binary splitters that i came up with, there is also a single minecart safe, and a chest storage room, i recomend that you explore the facility thourougly in order to see how everything works.
