Two teams, one small Technic set, and a whole lot of GBC chaos. See how both groups turned the same LEGO tractor into two wildly different—and surprisingly clever—great ball machine modules in this year’s GBC Set Competition Cup.
Read MoreGreat Ball Contraptions are almost ubiquitous at LEGO conventions. But where did the idea of a GBC loop come from and how was it standardized into the hundreds of amazing machines moving thousands of balls that we know so well today?
Read MoreWhat tools do you need to get started with a LEGO GBC module? Today, we explore the essential materials required to build your own Great Ball Contraption.
Read MoreDo you want to build a LEGO GBC module but don’t know how to get started? Build these five core mechanisms that make balls move and you’ll have your own Great Ball Contraption loop in no time!
Read MoreHave you ever wanted to design your own LEGO GBC module, complete with a story to wow people at conventions? Perhaps instead of creating a new function, focus on the style!
Read MoreHow do you build a LEGO Great Ball Contraption module from start to finish? Peek behind the scenes at the concept development, creation and testing of this soccer module to see if it scores a goal!
Read MoreCan you build a Great Ball Contraption using only one small LEGO Technic set? We found out by hosting a competition at LEGO World Utrecht and the results were impressive, resulting in some amazing GBC alt-builds.
Read MoreEver wonder how those Great Ball Contraption gizmos worked? Or what they're called? You can count on Ronald Vallenduuk to explain it all, and rest assured, he won't drop the ball...

Read MoreI’ve always been fascinated by great ball contraptions, or GBCs. They’re wonderfully complex design to do a wonderfully useless action tickles my Rube Goldberg fancy. Builder and mechanical evil genius (ok, not so evil) JK Brickworks has crafted his very first GBC, and of course it’s a wonder to behold. Watch the video to see it in action.
Check out this awesome feat of pointless engineering, the six-headed great ball machine. For the uninitiated GBC is a collaborative event at a great many LEGO conventions and exhibits. The idea is to build a machine that accepts LEGO balls (Zamos Spheres, basketballs, etc) on one side and cleverly convey them to the opposite side to deliver to the next module. Why? Because balls, that why!

Today we are joined by Katie Walker who shares the concept of a “Flash MOC” and the evolution of one of her stunning backlit LEGO cheese slope mosaics.
Today we are joined by Katie Walker who shares the steps of creating a LEGO cheese slope mosaic that almost looks like a stained glass window.
What is a LEGO cheese slope and how can you tessellate them to make patterns that dazzle and amaze? This tutorial will teach you everything you need to know about cheese slope mosaics.
Can LEGO Botanical sets be used as “tree battle packs”? Yes! Here’s how to transform 10373 Mini Bonsai Trees into minifig-scale trees for all your MOC needs.
August is here with a fresh selection of LEGO contests and challenges. Don’t miss your chance to build a MOC and maybe even win some awesome LEGO prizes. With Frogust, Paradisa, and even some stop-motion in the mix, there’s plenty of inspiration to start building!
Sometimes the best LEGO projects solve problems nobody actually has. Follow the design of the Kong-o-Matic 2000, a motorized machine that plays LEGO Donkey Kong so you don’t have to!
Now you can build your own iconic upscaled LEGO tree! Instructions are available right here on BrickNerd and in BrickJournal’s most recent issue.
