  • Lego GBC Batch Counter

    Lego GBC Batch Counter

    Lego GBC Batch Counter is a Lego Great Ball Contraption Module built for the Great Ball Pit – Challenge 2020, and is a module designed to output a batch of exactly 13 balls (or a range from 2-30) in a single batch.

    You can read more about the challange here https://www.greatballpit.com/2020/09/great-ball-pit-challenge-2020.html

    Program

    The program was written in Lego’s block language and has 3 main parts

    1. Button event capture, for capturing the inputs from buttons and changing the target count and motor speed variables
    2. Distance counter loop, for counting the number of balls passed.
    3. Motor control loop, for running the conveyor or tipping ramp.

    I also setup a control panel with buttons and guages to see what was going on.

  • Lego GBC 9

    Lego GBC 9

    Lego GBC 9 is a steampunk themed module that carries the ball through a 9 shaped path on their way to the next module. It uses a continuous loop chain and pushes it to its limits by taking a Mobius strip style of path and given the strain on the chain I expect this to be a short lived module.

    Night Lighting

    For this module I used a string of UV Leds shining on the back of trans-neon panels, the ball path itself is not directly charged.

  • Lego GBC Donahue in Red and Blue

    Lego GBC Donahue in Red and Blue

    Lego GBC Donahue in Red and Blue are builds of GBC Donahue, a simple and reliable chain lift module that was the the4 Brickworld workshop module.

    These builds of this module are a blue and red variation with a couple of gearing and support changes to make it sturdier when transporting it around for shows.

    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-red/blue brick to color the module.
