Retrievulator





The Retrievulator is a block from the Tubestuff mod.

It is similar to a Regulator, with noteable differences.

A Retrievulator must be placed next to a powered Retriever to work with an invenstory block on the other side, such as a chest, relay, or ejector. IC2 machines do not apear to work with it.

Inside the retrievulator GUI, there are two sections: R for Retrieve, and T for Threshold/Transmit.

The R section is the input buffer. It will be placed into the Retriever one stack at a time, while the connected output inventory has less items than are in the T section.

The T section sets a threshold for retrieval. If the connected inventory has less items than are present there retrive more.

The Retrievulator will emit a constant redstone signal when the inventory directly next to it contains at least the items in threshold.

It will emit redstone pulses to all ajacent blocks (including the retriever) when the connected inventory contains less than the items in the T section. The retrievulator does not require EU or restone signal to work.

Setup
The Retrievulator has an input and an output face. Make sure that the input face is facing the Retriever. The Retriever needs to be powered with blutricity. Now you must make an input chest and an output chest. The input chest must be connected (with Pneumatic Tubes) to the input face of the Retriever. The output chest must be connected in the same way to the output face of the Retrievulator.

Now you can fill the retrievulator's GUI. The R side is the amount the retrievulator will pump into the output chest, and if the output chest gets lower than the T side of the GUI, it will pump the same quantity of items specified in the R side to the output chest again. The input chest can be filled with the resource you want to pump to the output chest.
