Back in 2018, we created the GBC 27 Pinball Madness Machine — an interactive Great Ball Contraption built from the LEGO 42076 Hovercraft set. A full-on pinball experience with moving mechanisms, manual controls, and endless fun.
And we still love seeing it come to life all over the world 🙌

🔌 Small cables. Big possibilities.
Not every LEGO creation fits neatly into standard connections — and that’s where our custom adapter cables come in.
Whether you’re combining different components, powering unique builds, or pushing your design beyond the usual limits, these cables make it all work seamlessly.
Built for creators who don’t like restrictions. 🧱⚡
From clean setups to complex engineering projects, our adapter cables help bring your ideas to life — exactly the way you imagined.

🎶 LEGO meets vinyl… and it actually works.
One of our customers just built an incredible fully functional LEGO record player — and yes, it plays real records 👀
Huge thanks to Jorge Pereira from Portugal for this amazing creation 🇵🇹
The secret? Our custom LEGO turntable needle bringing this build to life.
This is exactly why we love this community: creativity, engineering, and a bit of nostalgia all in one build. 🧱💡

Our GBC 36 Crazy Carnival is now being built at the GBC Camps organized by BeyondBlock — using the instructions we provided.
It’s always awesome to see it coming to life in someone else’s hands and running in a real layout setup.
Huge thanks to BeyondBlock for sharing the video 🙌 really appreciate it!
Can’t wait to see the full GBC layout in action with all the modules together.
⚙️ Behind the Scenes… ⚙️
Here’s another exciting update on our upcoming GBC 60 Funhouse!
This new preview gives you a closer look at the gear system powering the module. A whole network of gears is working together to drive the different mechanisms — creating smooth, synchronized motion throughout the build.
Designing this took a lot of fine-tuning to get everything running just right… but the result is incredibly satisfying to watch in action. 👀
And yes — this is only part of the story. There’s still more to reveal as we continue working towards release! 🎡
