Impulse Hopper - HenryLoenwind/EnderIOAddons GitHub Wiki

The Impulse Hopper (new in version 0.2.0) is a bit like a hopper (hence the name). However, instead of simply moving one item a time from its input, it always moves a complete "set". And the set can be configured. So you can tell it, that it needs to move "1 red flower, 17 stone bricks, 5 gold ingots and 1 potion of invisibility" at a time. It will then do so---but only if it has all the items.

It can be configured to act on redstone signals like the Ender IO machines, but it has 4 more modes: "Rising edge" moves one set of items every time the redstone signal changes from "off" to "on". "Falling edge" does the opposite. "High pulse" moves a set when the redstone signal goes all the way up after it has been off. And again "low pulse" does the opposite.

The GUI shows if the Impulse Hopper can move a set of items. Unused slots have white arrows. If all is OK for a slot, both arrows are green. The upper arrow turns red if there are not enough input items. The lower arrow turns red if there is not enough space in the output slots.
