Welcome to Planet GBC


My name is Paul G., aka Turbopolofr, and I’m the owner and designer of this Website.

The aim of Planet GBC is to build a central hub focusing on one of my favorite hobby, Lego ® Great Ball Contraption (GBC).

Planet GBC will progressively centralize for you every useful information you need to start or progress with GBC modules building, providing you links to the most popular GBC modules builders, some tutorials on GBC technics, as well as building instructions so as to reproduce easily amazing machines.

There is no commercial structure behind this website, just a single person, passionated by Lego GBC, trying to propose the best experience as possible with Lego GBC to a maximum of people.

Planet GBC is the website I would have loved to find while starting with Lego GBC. I hope you will enjoy it.

If you do, do not hesitate to share its URL with friends and to leave me a message
