Hmmm. See, unlike lapis, gold actually has some use. It can make golden apples, powered rails, clocks and some other stuff. Lapis can only make a block and a dye. That is the reason I chose lapis over any other item.
The two centre pistons are meant to be directly next to each other whilst the others are 1 block away from the centre pistons.
How current would flow:
In the top image you can see that if redstone and lapis are directly connected in a line a current will not pass through them. If you use a converter (bottom image) then it will allow them to be used together like a repeater boosts the length of the power.
Sorry guys I can't accept you. I am looking for over 16's only because I cannot control anyone's language or references. Also I don't want children in my faction. Sorry.
