RedPower Logic Parts
RedPower Logic Parts can't be placed in the game world, but are instead used as components for crafting other logic items.
Any furnace can be used for the Stone Wafer.
The Stone Wafer is used in the creation of most of the RedPower Logic recipes. It is the most basic component of all logic gates and cells. Some of it's most notable usages are in the Timer, Wireless Receiver, and the AND Gate.
