This is a new type of module that I designed. It consists of two main arms that throw the balls over a short ramp. The loading of the balls into the arms is done by a stepper, followed by a pair of rods that tip the ball into the opposite arm when the other arm is in the upright position.
The module is compatible with GBC standards. It has an output of one ball per second. Input level is 10 blocks high, output level is slightly higher.
This module also is part of a modular system where several modules can be connected to eachother and share the same motor.
A modular system of four GBC modules. The modules can be arranged in any order. They share the same axle and only one motor is being used. Average output of 1 ball per second.
