Create your own GBC by combining some of our modules and connect them together in your own custom loop. This is very possible and Szilard Gyalay from the USA proves it. He combined some modules from our GBC 36 Crazy Carnival. Can you spot which ones?

This is what he wrote himself:

This build is inspired by GBC 36. The original PV-Production build features two of my most favorite elements. I used a very compact format for these two with a tight return circuit.

Yet again a build inspired by a PV production design and added my “spin to it ” and just my own lego pieces and fun, no need to own the set. Use your imagination to make it work. That is what Lego all about is in’t it ?

Got the new LEGO 42152 Firefighter Aircraft set this Christmas? Great, you now have all the parts necessary to build our GBC 52 Flight Fair.
Monique Simon from Luxembourg had the same thought and build it in record time with our building instructions.

The amazing builders from the Beyond Blocks Workshop (in the UK) took on a new challenge.

After building our GBC 23 Ball Color Sorter they decided to create their own software in the programming language Scratch. This visual programming language makes it easy to get started in software development. And they did a great job!

There code is (not yet) the fastest but it can sort out the different colored GBC Balls, just like our original software does. When watching the video you can feel the tension and excitement being present in the room. Great job and keep those videos coming!

Earlier this week, a very proud father (Canada) send us a video showing our GBCs that his son has build. Both wish to stay anonymous and of course we fully respect that.
This is what he wrote to us. Couldn’t make our day better after reading this!

I am sending this because my son wanted to show his Geneva Drive. He built. played, disassembled and rebuilt Geneva Drive for some times since August. Children played GBC #49 Geneva Drive and #52 Flight Fair this holiday. Those GBCs made our holiday much more fun. Thank you for all those products and services, and we wish you all a Happy New Year.

Tip: Turn up the volume if you want to stay in the Christmas spirit ;)

Beyond Blocks has the answers! This is quoted from their website. Spoiler, don’t buy new LEGO directly: Get our building instructions to rebuild with your existing parts.

My next recommendation for what new LEGO kit you should get your child for Christmas is….nothing.

LEGO is the most versatile toy on the planet. It’s designed to be taken apart and put back together in different configurations and one of the aims of Beyond Blocks is to get people to a level of skill where, rather than wanting a new set, you should be able to see the possibilities already in the LEGO you have.

If your LEGO loving child already has some Technic sets at home, instead of buying a totally new set for Christmas, why not try something different and get instructions for building something amazing from the set(s) they already have?

PV-productions share our values of making your LEGO go further and they create instructions for building the most amazing Great Ball Contraptions (GBCs) based on single LEGO Technic sets. A GBC is a complex machine built from LEGO to move balls from one place to another and some of the designs that they’ve made are breathtaking.

PV Productions have made some epic GBCs, making use of the huge LEGO Technic sets, but also have some really great ones for smaller sets too, like this Geneva Drive made from the LEGO 42120 Hovercraft, which you can pick up for under £40.

So why not dust off that LEGO Technic Bucket Wheel Excavator that your child has made and hasn’t touched ever since it was finished, take it apart and build something epic over the Christmas break that makes them look at their kit with wonder again.

LEGO wasn’t built to stay on a shelf and be looked at!

Szilard Gyalay from the USA build our latest GBC 52 Flight Fair made from the LEGO 42152 Firefighter Aircraft set. Once setup correctly he made a nice video of it in action and even including an epic slow motion part where you can see the GBC Balls fly. See around minute 00:40. See also his review here below. Thanks for sharing with us!

GBC 52 Flight Fair - 42152 Building Instructions

Szilard Gyalay - December 7, 2023

GBC 52 is a new twist on moving the balls. The catapult mechanism is a new and simple one. I loved the incorporation of the propellers to "propel the balls" so all can yet again line up for being deployed. All in all a solid build, some fine tooling required. Motor speed needs to be experimented with. Because of the lunching mechanism design, used a stronger engine. Simple . low cost and efficient.
