Lego GBC Brickworld Ball Pump is a reliable ball pump module designed by Brian Alano.
I have blue and red builds of this module and use them regularly at shows due to their reliability.
The module is highly extensible and I use variations of it in several of my other modules.
Night Lighting
The modules are setup for night running as well.
They use my custom Lego UV/Led lights, with the UV shining on the balls and the Lego light passing through a trans-green/yellow brick to color the module.
