Advanced wafers are pretty essential in Galacticraft. You need it for a NASA workbench which is how you build rockets in the first place!


A Redstone Repeater has to be placed in the top right slot of a Circuit Fabricator (Crafted with 2 tin ingots in top corners, aluminum wires in bottom corners, furnace in the middle, redstone torch on bottom, lever on top, and 2 buttone in remaining spaces), along with redstone dust in the center and two Silicon pieces in the center.
