Component: Diode

The Diode is one part of the redstone repeater. As its name implies it permits power to flow in only one direction. The direction is indicated with a knob at the head of the diode.

The diode does not offer as much variety as the generic cable. It is placed in a manner that the power flows the direction you are facing or, if sneaking, the opposite direction.

In the future when elemental current can be extracted from crystals, the diodes will open a GUI when activated that shows a filter of the types of elemental currents allowing for an even more compact design and programming eventually.
