Ender Eye-Fi Mod which is a pretty noticable mod in Minecraft aims only to create an easier, less cluttered method of sending redstone signals through large distances.
4 new Repeater types: an ender powered repeater, 2 signal converters to convert redstone signals to and from ender signals, and a modified redstone repeater sharing its ender counterparts ability to redirect signals. Ender Repeaters work similar to redstone repeaters with the added feature of sending signals without the need for redstone dust. Ender Repeaters can send unobstructed signals up to 15 blocks away. Ender signals cannot be used to power redstone mechanisms (e.g. doors, trapdoors, etc.).
Signal repeaters Repeats a signal of the same kind
Signal converters Converts a signal
(Top left) RR Repeater, (Top right) RE Converter, (Botem left) EE Repeater, (Bottom right) ER Converter Repeaters may only receive and transmit signals of the same kind.That is, an EE Repeater may only receive a signal from other EE or RE Repeaters, and transmit a signal to other EE or ER Repeaters; and an RR Repeater may only receive a signal from other RR or ER Repeaters, and transmit a signal to other RR or RE Repeaters.
Converters may only receive a signal of one kind and transmit a signal of the other kind. That is, an RE Repeater may only receive a signal from RR or ER Repeaters, and transmit a signal to EE or ER Repeaters; and an ER Repeater may only receive a signal from EE or RE Repeaters, and transmit a signal to RR or RE Repeaters.

EE Signal Caster
RE Signal Caster
ER Signal Caster
Signal Casters are similar to Repeaters in that they can transport and convert signals in the same way Repeaters do. Signal Casters are meant only to transport signals. Unlike Repeaters, Signal Casters cannot be locked but will still block any incoming signals from passing regardless of its orientation. Signal Casters are considered full blocks therefore do not require a solid block underneath to stay. Signal Casters cannot change delay unlike its Repeater counterparts but instead has a fixed 1 tick delay. More than the Repeaters, Signal Casters feature a 6-sided input/output redirection function and can be pushed or pulled by pistons.
Signal Caster Eye
The Signal Caster Eye is a special Caster block that constantly emits an ender signal in all 6 directions.
