Lego GBC ball pump

My idea of a GBC ball pump. I was inspired by philo´s webpage, but I decided to change some things in the desing. First of all the hopper is different: I used plates to do it. In philo´s version there is a round dish instead of the plates.

The pieces are yellow and black becouse of availability; I have lots of yellow and black liftarms but no more than 10 or 20 orange liftarms, for example.

It features a lego fower funcions M motor with the same reduction of my latest GBC. I also included large pins between the 1×15 liftarms to make it sturdy. This module need at least 8 balls to work well. It has an error: sometimes the balls doesn´t fit. I don´t know why…

Here is the photo of the reduction:

Hope you enjoy!
