I build the Ball factory and it is tricky to get timing right so that everything runs smoothly. I used the 5.5 axle.To assist you, the Rebricker created a complete video on the timing setup for the Ball Factory.

A nice variety of GBC modules and I especially liked the Mountain diorama at 3:10. The use of themed modules and themed minifigs throughout the loop was a nice touch. Overall a very nice GBC loop to watch. Thanks for sharing so others can enjoy and appreciate the hard work and creativity presented in this collaboration.

I see the Zig-Zag Steps module was removed from the list and replaced by the Pinball module. I like the Zig-Zag Steps and was wondering if it's a temporary or permanent removal?

Yesterday, I wanted to order one from Lego online but they were out of stock, so I picked one up from a Lego store at Potomac Mills Mall in Woodbridge, Virginia (USA), and they had several sets available (when I as there). The Lego store only allowed one set per customer, which is encouraging. Hopefully Lego has the same policy all around so folks won't be able to horde the sets. I'm looking forward to the build.

I use a Surface Pro, which is very handy. It's thin, very portable with a built-in adjustable stand to change screen angles and a detachable keyboard. It also has a touch screen, so you can zoom in on the instructions to get a closer look at certain parts or building steps. Has a video player to watch video building instructions and other software like Word and Powerpoint for other building instruction formats. Another big plus is It also has a USB port, so you can attach an external hard drive or USB stick to expand your memory or access a large library of PDF instruction files. IMO it has advantages over an iPad and a little more portable than a PC.

I totally agree that GBC is (very) addictive. I was bitten by the GBC bug in 2011 and since then I have built more than 20 GBC modules and have been part of several GBC loops at LEGO events ever since. My first Akiyuki module was in 2012, when I built the blue Archimedes screw, from watching the video. I also built the cup-to-cup from photos and the video. Then last year, I followed the Rebricker and built the Ball Factory (my favorite module) and this year the lift triggered by a stuck ball. I greatly appreciate all the effort by everyone who put everything together and for sharing Akiyuki's creations. This forum also adds fuel to the GBC fire

That was funny and entertaining. Thanks for your efforts to create and for sharing the video.

I attempted to recreate Akiyuki's GBC module two years ago from watching the video and using the few photos that existed at the time. I made some progress, I built the input, cup-to-cup ramp and part of the spiral lift but never finished the project. Seeing this post has given me additional reference material and new energy. I'll have to get my partially completed module out, dust it off and finally finish building it. Thanks for the thread and inspiration, nice work David.

There are no instructions for this module. I was able to recreate it using the photos Torso posted on this thread, watching the video and a 3D model of the Cardan Lift posted on Swebrick. The 3D model was made with LeoCAD and many of the parts are not aligned properly, but I was able to create a functioning module from the resources provided. The only tricky thing about it is to synchronize the arm.

With Torso's permission, I built a version of his Cardan lift design and put it on display in a GBC loop at Brickfair Virginia 2015 (July 29 - August 2, 2015). The module ran flawlessly during loop testing and two public sessions. Each public session was about six hours of continuous running time and there were no issues or problems at all during operation. In my opinion this module is designed very well and capable of running very long periods of time without error. Excellent work Torso.

Awesome review and the photos are fantastic. Thanks for taking the time to create and for sharing your review, it is greatly appreciated.

I picked one up at my local Lego Store the other day and am looking forward to the build. From the reviews I've read and videos I have seen, this should be a fun build.

My best bargain has been a complete 8547 Mindstorms NXT 2.0 set (retail $280 USD) for a mere $25 USD.
