New Lego GBC Module - Laminar Flow

 

This is Laminar Flow, my latest Lego GBC module that I built for the 2021 Great Ball Pit Challenge.  The main constraint of this years challenge was to lift a ball to a height of 24 inches (64 Bricks).  I achieved the height with a twinned conveyor powered by a Lego PF-M motor.

This module features a Zamor Sphere (Part: 54821) filter that recirculates the Zamor's inside the module, while Lego GBC Balls are allowed to exit.  Well... this is what's supposed to happen.  Sometimes the Lego GBC balls are also re-circulated, which is something I will need to improve in the future.

The filter is simply 2 beams spaced apart at a distance that allows for the GBC balls to fall through.  The new beams with pinholes on all sides (Part:71710) seem to work well for this application.



The gearbox is fairly simple, with the medium motor clutched and geared down so it can move the large conveyor without any issues.  The conveyor is tensioned like my other Technic built conveyors using a pair of light-grey spring shocks.



In summary, I'm really happy to have been able to use up the following quantity of parts that were sitting lifeless in my workshop:
  • Blue Zamor Spheres (Thanks VLC Diana)
  • Blue Duplo Slides that were once used in my 8 foot long slide video VIDEO HERE
  • Lots of LUGBulked Black 1x16 Technic Bricks and  Black 7x11 Technic Frames
This module is sure to have great table presence if I can ever get it to a live GBC event.  (Hopefully sometime in 2022).

Great Ball Pit - Challenge 2021


Welcome to the 4th annual Great Ball Pit - Lego GBC Build Challenge

Before we get into the details, let's take a look back at the previous 3 winners and their modules.

(2018) "16x16" Winner: Serendibite

(2019) "Wheels Up" Winner: Ryk Field

(2020) "Bakers Dozen" Winner: Sam Friesen



2021 Challenge

This years theme is "Great Heights" where the challenge is to build a module which will lift a ball up to a height of at least 64 bricks ( 24 inches / 61 centimetres ). This will be referred to as "The Minimum Height" in the guidelines below.

Module Guidelines

  • The module can have any size footprint, and use any lift mechanism.

  • Multiple lift mechanisms can be combined and chained together to reach the minimum height.

  • The minimum height is not the maximum height, there is no maximum height.

  • Once the ball(s) has/have reached the minimum height, anything is allowed to happen to them. I would recommend removing some of the energy from the balls before they exit the module.

  • The module must meet the GBC standards for input bin height (10 bricks high), and capacity (30 balls minimum in the input area).  Output speed needs to be "reasonable" which should be a maximum of 1 ball per second.

  • The module must be powered by official Lego components such as: EV3/Mindstorms, Power Functions, Powered Up, Boost, or Control+.

  • The module should be something that has generally not been seen before.  Existing mechanisms are *OK* but try and be original.

  • If you have any questions about the module guidelines please PM me on Discord.
