The London AFOLs held their annual Great Ball Contraption display last weekend at the London Model Engineering Exhibition at Alexandra Palace in north London. As usual, the adults loved it and the kids were entranced. Here you can see the complete layout.
I normally exhibit my Great Ball Contraption models with my LUG, the London AFOLs. But recently I was invited by friends in the Brick Alley LUG to take my models to their Shildon Brick Show in the North East. The line kicked off with a series of my GBC builds, which then fed into some really nicely themed models from the Brick Alley members, many of whom were first-time GBC builders. There were some familiar designs on show, but also a few which were original concepts, so it’s great to see how much they achieved for their first GBC lineup at a show.
Well here you are – I present the video that none of you have been asking for – showing the full circuit of all twelve of my Great Ball Contraption modules, feeding each other in a perpetual cacophony of noise and spilled balls. I can’t link to each video for an individual module, but you can see them all in my GBC Playlist, or search for the specific module name on my YouTube channel, which will appear as we go round the loop.
This is my Rainbow See-Saw GBC module. It is based on a design by Lasse Deleuran at BrickHub.org. His version is called the Modular Tipper, you can find the building instructions linked here.
The Great Ball Contraption layout at Skærbæk Fan Weekend in Denmark was very special this year. It’s the first time that three GBC big guns have been in the same display – namely, Tom Atkinson from the US, Maico Arts from the Netherlands and Akiyuki from Japan! The trio were brought together for the event by YouTube channel Beyond The Brick, who have been covering GBC around the world for several years. When I heard they were going to be there, I knew I had to take some of my own GBC modules to play along too.
Unlike many of my other GBC modules, which I have built from other people’s plans, Buckets of Fun is one I designed from scratch myself. As this is usually a long iterative process, it has taken me quite a while to refine its performance to be reliable for long periods at a show. Here is the latest version:
