ME Level Emitter

An active Level Emitter
The ME Item Level Emitter can indicate either the level of a specified item or the ME Network energy level. You can set the threshold and if the ME Item Level Emitter will emit a redstone signal or turn it off.
Requires a channel to function, if its power or channel is lost the emitter will switch to an off state.
These can tap into the crafting system when a crafting card is installed, allowing you to output redstone while an item is being crafted, or even configure the system to output redstone to preform a crafting task, its important to note that you cannot mix level emitter craft via redstone with interface patterns.
