Current Redstone knowledge:

Past Redstone Experience: 
My best creation are ,1)Display,2)Binary 1 adder using piston,3)Binary adder, and 4)triple piston extender.display is by a repeater behind piston to make i twork in a pattern so it does not mixes the wires.Binary 1 adder is my verycompact machine.It adds 1 in binary and it infinitly expandly expandable.
