  1. The Sun is a GBC module created by @PG52 The video of it in action is here: With his help, regarding additional images, I have created some PDF Instructions for it. The PDF file and Parts lists can be found here: http://kanatta.com/GBC/TheSun/ If you want to link to the instructions etc., please just link to that page, as it contains mods, additional images, credits etc. The parts list isn't included in the PDF as Stud.IO isn't very flexible with that sort of thing. The digital file is not currently available. Known issues: I can jam and doesn't have a clutch system to deal with that. It is also a self feeding module. @dunes is currently working on a GBC circuit friendly version. In the instructions, there is a mod to replace the curve at the bottom of the top ramp. This is to remove the twist the flexible hoses cause which pushes the top ramp into the wheel. Notes: For the most part I have used commonly available pieces in regards to certain axle/pin colours. Where this isn't the case, it was done for specific aesthetic reasons and you can of course use the more commonly available colours. I think I mainly just did this for "The Sun" sign. Thanks to: @PG52 for creating the module in the first place and for the additional images. @Doug72 for helping to test the instructions. Additional: I have also added a mod for the Cardan Lift and will be doing instructions for Akiyuki's Cup-to-Cup v1.1, which is the version he is currently running, rather than the one which got reverse engineered close to the time he created the module. These are and will be available here: http://kanatta.com/GBC/ Enjoy.
  2. A new topic to attempt to centralize information, improvements and discussions about the most iconic Great Ball Contraption made by Kawaguchi Akiyuki, The Ball Factory GBC Version 0, July 2008 by Superbird28. Akiyuki stated himself he was inspired by Superbird28 when designing and building the Ball Factory. Why can be clearly seen in this video dating back to the pre-digital age. Thanks @Jonas for noticing. Version 1, June 2011: with color sorter as input: Version 2, november 2011: picker for 2 balls and optimized for higher speeds (1.3 balls/s) Februari 2016, @Blakbird and @TheRebricker reverse engineered the Ball Factory over a period of two years and posted the below: Video instructions by The Rebricker PDF instructions by Blakbird 4428 parts MOC Review by Blakbird LEGO Digital Designer file by @TheMagician The Akiyuki Project topic by Blakbird April 2019: Ball Factory New Style GBC compliant, reliable and easy to move: A big thank you to Blakbird and TheRebricker for all their hard work! This reverse engineered version adds the option to circle balls within the ball factory, here my build from December 2016 Many have build the Ball factory in various colors and versions. Below an overview of suggested and quoted improvements with pictures out of the 77 pages in The Akiyuki Project topic, up to you what changes you want to make. Feel free to add your builds, improvements or questions about The Ball Factory to this topic. ___________________________________________________ Spiral Lift platform improvement by Jonas: used a SNOT technique to get a stronger platform. It allowed me to remove the gap and to fix the superstructure to the studs. Moreover, I used the remaining stud of the 30414 brick to stabilize the tower column by a vertical 1x6 tile. Now, each column is fixed from 3 sides and the tower is really stable. It will survive even an accidental kick.  And, I added another (third) black pin to strengthen the vertical support (shown on page 186 in Blakbird's manual) ___________________________________________________ Ball picker improvement by Jonas: I have also made a small improvement of the ball picker - the part that picks a pair of balls and puts them into a bucket. It happened quite often that the right ball dropped before it reached the bucket. When I analyzed the construction of the picker, I noticed that the rightmost axle is significantly looser than the other ones. While the other two rear axles are attached to the rail construction, this one is not and cannot be attached. In my version, I fastened this axle to the rest of the assembly by replacing a 3L liftarm by an L-shape liftarm (not necessarily in yellow color). -> Since that time I have not observed any earlier drop. ___________________________________________________ Back pivot point by @Ankoku I have used the 5.5L Axel with Stop just like the original. You could probably get away with a 5L, but the connection may be hanging off slightly. The main piston rod has been changed from 20L to 19L in complete length. I used the "Technic, Plate 1 x 5 with Smooth Ends, 4 Studs and Center Axle Hole" which Akiyuki used, just because I did have them kicking around spare. A 6L Plate would be fine. I have gone with a 11L and 7L lift arm. Akiyuki went for a 15L and 3L, thus far, I haven't seen any reason for using those particular lengths. One bonus with using the plate to connect the two lift arms, is that the connection is rock solid, so you no longer have the wobble of the altered version. As you can see on the right, the connect on the end of the 8L axel is flipped. In the ReBricker instruction video, he has it this way round and then adds a later correction to show it the other way around. This way round is the way it is in the Akiyuki video and it is required to make this pivot point work. ___________________________________________________ Bucket shift timing mechanism by Ankoku Here is the piston itself. I have changed it to the original format. This is obviously the left one of the two in the video, as you can tell by the connector end, but other than that, the two pistons are identical. The crucial change is Technic Beam 1x3 Thin between the two year 1x5 Technic Beam Thick. The reverse engineered solution doesn't have that. That provided the extra travel I was looking for. As you can see, the connections for the yellow beam on the right aren't as pretty and you lose the symmetry. That said, the new motion is as smooth as butter, which is immensely pleasing in comparison to trying to make the other method work. ___________________________________________________ Bob improvements by Ankoku The initial changes to the height didn't do much to improve smoothness and I found that the paddle seemed to now be an issue. It was also the source of quite a bit of friction. As you can see in the image, the paddle is 3 deep in total. You can tell this from the light grey 3L axel. The bottom part of the paddle is a Technic Beam 3 x 3 L-Shape Thin. Using that piece makes a lot of sense and seems far better than using 3x Technic Beam 1 x 3 Thin, where the 1st of those completes the light grey 3L axel length and the other two are at 90° to create the L shape. Unsurprisingly, this approach is smoother as there is less friction. ___________________________________________________ Bucket unloader by Ankoku So I was playing with it and it didn't seem to work very well and certainly didn't reflect the motion I was seeing in the Akiyuki video. Having watched the video more times than I care to remember, I noticed that the lift motion seemed to be in a single motion, not two. I also noticed that the lift arm used seemed shorter than the one in the instructions. So in the end, I changed it from a Technic Beam 1 x 5 Thin with Axle Holes on Ends, to a Technic Beam 1 x 4 Thin with Axle Holes on Ends, using yellow ones to reflect those in the video. This seemed to work well and reflect the video. Then I checked on Bricklink and it seems that Technic Beam 1 x 5 Thin with Axle Holes on Ends don't come in Yellow. So yeah, that bit needs to be a 4L not a 5L. ___________________________________________________ Back slider by Ankoku, There is definitely these two beams there, length unknown. Below I am using 2x Technic Brick 1 x 15. You can see both in the Akiyuki video, although only 1 at any one time. This also explains why the bottom Technic Axle and Pin Connector Perpendicular is attached differently to the two above it. For the forward back motion you see in the video, this is not possible with the use of a pin instead of an axle. The axle you can see here, allows full motion in one direction, but slightly limited in the other, which is exactly what you see in the video. It is only possible to put the top Technic Brick 1 x 15 in there if you remove the plates from the bottom of the slider. If you look in the Akiyuki video, those plates are not there. I still don't know how either piston connects to the slider exactly. I am still hoping to hear back on that. That said, these two beams seem to be correct and answers a few questions. ___________________________________________________ Bucket slide by Ankoku The area that the buckets slide along for the shifter is actually offset by half a stud in the Akiyuki version. This is not reflected in the instructions. This answers why the shifter itself is half a stud over the sliding area at maximum backwards reach. I always thought the shifter didn't do full travel, but it does, it is just the sliding area which is misplaced. Here you can see how the sliding shelf is connected to the conveyor with a Technic Brick 1 x 2 [2 Holes]  Anyway, changed the length of the slider my one, so that is now correct. Removed the plate from the bucket stopper just before the slider, so that is now working correctly and is the same as the video. Bob now actually aligns correctly with the buckets at maximum reach. ___________________________________________________ Shifter changes by Ankoku This removes the need for any universal joints and thus removes the variable speed of the conveyor. ___________________________________________________ Shifter changes by Ankoku It seems Akiyuki has reworked the pivot mechanism and beam length. This new approach removes any potential bend in what would have been an 8L axle. The new approach requires a shorter piston beam, a longer beam under the shifter. The brace is 2x Technic Beam 1 x 6 Thin. Here, you can see the positioning of the pivot point, the indentation in the conveyor tower, which is 2 bricks deep to allow the pivot arm to travel that far. You can also see the black axle instead of the grey one, as it requires that extra 1L for the back and forth arm to pivot one. At the top, you can see where the slider platform connects and how it is moved 0.5L across. Shifter Changes in action: ___________________________________________________ Ball dumper by Ankoku It sits at the right height, the ball router works well and the axle housing is aligned correctly. As you can see above and below, I have added blockers to either side, which means that a renegade ball can't escape up hill. Balls can only pass when the router is in the correct position for that route. Inside is only 2 wide now and doesn't have any pins etc. ___________________________________________________ Ball unloader by @smdzucladoc After seeing Ankoku's mods as well as his detail photos of the bucket shifter, My ball factory has been much improved. I was still having a lot of friction in the ball loader until I add these mods. Now the ball loaders is very smooth. I add a 1x3 liftarm in between the two Axle and Pin Connector Perpendicular Triple and it seems that the loader doesn't bind to the axles anymore and it is very smooth. I also added some additional bracing to the back of the ball loader. I added two additional Technic, Brick 1 x 2 with Hole and a 1/2 bush to the bottom axle. I also change the axle 3L to 4L and added 2 Axle and Pin Connector Angled #1 and then a 6L axle perpendicular to try to brace the 12T and 40T gear as perpendicular as possible. ___________________________________________________ For inspiration, this extended version by @Jonas and black version by @Thunderthumbs
  3. G%$ #@&% it. Thanks to Akiyuki, The Rebricker, and the rest of you &%$*ers, I've now caught the GBC bug and it is going to cost me a lot of time and money. It all started with Akiyuki. Well, GBC didn't start with Akiyuki, but I was more or less "meh" on the whole concept until he came along. His ingenious mechanical solutions are mesmerizing, perplexing, and wonderful. Although I admired them from the start, I figured there was more or less no chance of me replicating them from the videos, especially since the one I was most interested in was also the most complicated: the ball factory. My involvement therefore remained stagnant (and non-existent) for a couple of years until The ReBricker showed up and proved that you really could reverse engineer the Ball Factory and then went one step further and posted video instructions for the whole thing. "Fine", I thought, "I'll just build that one." A few months of LDraw modeling, part collecting, building, testing, and display case building later I was hooked. It was one of the greatest building experiences I've ever had. This forum has repeatedly wished for a comprehensive set of instructions for the GBC modules of Akiyuki, and I've decided it is my responsibility to help make your dreams come true. With that in mind, I've compiled a list of all of Akiyuki's 28 non-Mindstorms modules with the goal of creating and/or finding complete PDF instructions for as many of them as possible and compiling the resources here. I've made a lot of progress already. Here is the list along with whatever I know about building material available.

I'm a stickler for accuracy, so I'm trying to get as close to Akiyuki's originals as possible. I already have PDF instructions ready for 4 of them and just need to test them out. As I build each model, I'll post a mini review about what I've learned and then I'll post links to the instructions and parts lists so anyone else can build them too. (Update: See bulleted list above for which instruction files are currently available.) As always, help is welcome. If you have successfully built any of these modules and are willing to share your information, please let me know here. In particular, I need LDraw files to make instructions. In a pinch, I can make them myself if you have detailed photos. In an even tighter pinch, I'm making everything myself from the videos, but it is slow going. Enjoy!
  4. A new topic to attempt to centralize information, improvements and discussions about the most iconic Great Ball Contraption made by Kawaguchi Akiyuki,GBC Ball Cleaning Machine The thread is also a centralized location for all variations as well as newer design concepts of Ball cleaning machines.
  5. Great Ball Contraption (GBC) - General Discussion and Index This is a topic used for GBC general conversation, questions, hints, tips, etc. This first post will be used to maintain an Index of GBCs here on Eurobricks or other websites. Eurobricks topics LEGO GBC 8 + Building Instructions (5 modules - 2 motors) New Akiyuki GBC Instruction Index Other sources Greatballcontraption.com
  6. On Tuesday October 15, a free GBC workshop is organized for children in the age of 7 to 14 years old. The workshop is organized by Sioux Technologies to promote science and technique for the next generation. Location is Esp 101, Eindhoven (The Netherlands). Two of the models of Philip Verbeek (PV productions) will be used in the workshop. Philip himself will be there as well as trainer. More information can be found here: https://www.sioux.eu/ (please note that the workshop will be available in Dutch only, so is the information at the Sioux website).
  7. welcome to the mindstorm section of the Akiyuki project, this topic is for the modules of Akiyuki that have mindstorms in them or use mindstorms in any way. I will work with Blakbird to get instructions for these modules done, as always I would appreciate any information (pictures/videos) of these modules working or built here's what I know so far: Ball Cleaner EV3( in progress by @Juroen) program by Akiyuki (instructions not yet available) Container Transporter NXT instructions available here by @Courbet Fast Ball Sorter EV3 instructions by Courbet, built by Courbet and Mogwai, program also by Courbet and Mogwai, Render by Blakbird(instructions available) building instructions, program for the ev3 any help would be good to get these modules made into instructions (programs will also need to be made) 9v system

    GBC Event Kit

    This question is for folks that set-up GBC modules at events. Do you have an emergency/breakdown/set-up kit that you take to events? If so what do you have in your kit? I did my first event this past weekend and would like to make sure that I am better equipped for the next event which will be in October. Thanks, Daniel
  9. Hi everybody. This is my first post (except the "members' introduction"). Not being sure if it is the correct way/place to start I at last go into posting about my GBC projects, which are all only at WIP stage now. I already watched and read a lot of GBC resources (events videos, standards, famous modules and builders, balls sourcing hints...), which gave me a few ideas of custom builds, which will be new ideas as well as "remakes". But my work is currently slowed down by a few difficulties when leaving the dark age (getting used to studless building techniques when designing custom only, missing parts despite a huge initial BrickLink investment), so the results would show up bit by bit only. So, for more concrete stuff, my most advanced work is on a compact cycloidal drive, of course inspired by Akiyuki's one, but being a fully custom from-scratch and trial-and-error build. At its current state, only the core mechanism is available and it runs smoothly. However the ball transport (currently built on only one cycloidal "tooth") seems to be the hardest thing to make reliable, and it is not yet the case. A stiffer chassis (with the input bin and agitator + secondary ball transport mechanism will be required too. I'll build it with bricks mainly (when I'll find an opportunity to pick up my childhood stock). The core mechanism features an outer ring of 8 teeth, based on an octagon made up of 6L axles and 135° connectors, and a 7-teeth cycloidal disc (and some associated tricks), resulting in approximately 2/3 the size of Akiyuki's original design. So is my prototype worth a picture right now ? (a few other modules are planned but I built only draft/mock-ups of the core mechanisms now due to the lack of parts.)
  10. Version 2 of my cup to cup GBC but actually third rebuild. I thought it already had a separate topic but apparently not, hope you don't mind I create this one. After running it at several events, where it was one of the favorites of the public, I updated the drive system to a more direct drive and better force distribution by driving the crank through a 36 teeth gear instead of directly on a single axle. Also added more steppers for better ball entry and exit with basket. Direct drive from the XL motor. According to the gear calculator from Sariel this setup has 46Nm compared to 16Nm for the previous one! This makes the whole GBC run smoother and more reliable resulting in no dropped balls during the half hour I tested. The turntables are mounted with neck brackets in the frame to get the correct gear distance. For reference, version 1 video here
  11. This lego great ball contraption module uses a set of "forks" attached to technic lift arms to lit the GBC balls to the next module. The lift arms have to lift when they can't turn any farther. The mechanism is very reliable, but it can't be running to slow. The mechanism that loads the forks looks weird, but it does work well. I had a hard time getting the design right but it works well now. If you want the LDD or Stud.io file you can get them here.
  12. After looking through the akiyuki project by Blakbird and seeing the success of it. It is time I steped up to the plate and create this thread so we can have a central place for all GBC instructions. so far here's what I have been able to find basic modules (great for beginners) simple conveyor module 2014 workshop module http://alittleslow.w...GBC Donahue.pdf brickworld 2015 wheel module http://alittleslow.w...GBC, rev 12.pdf slightly more complicated modules serpentine gbc module (under construction) http://www.moc-pages.../moc.php/407594 wheel gbc module http://alittleslow.w... Lift 12x12.pdf intermediate modules Akiyuki Lift triggered by stuck ball module If you find any gbc instructions post them here
  13. This Lego great ball contraption module uses mechanism with the transparent food covering type pieces (I have no idea what they are actually called) It is a reliable module, even though it looks like it is flexing a lot in the video. The tightness of the mechanism that holds the balls is able to be adjusted very easily to make sure that they pick up the balls each time. I have (as you can see) finally got some proper GBC balls to run my modules with. This module can hold one layer of them in the input bin before they get stuck, I would guess that that is about 30 - 35 balls. Like most of my recent modules it is compatible with my power sharing standard. The LDD file is on bricksafe here.
  14. Well, I was amazed by this GBC, when I first saw it last year, and decided to try to reverse engineer it. Thanks to a few good pictures from the creator: ykuramata05, I started work on it... That was over 6 months ago.. and I got stumped on a few bits.. so it got put aside Finally had a clear workbench the other week, so decided to get back to it, and managed to finish it off.. funnily enough - 2 other builders - @alanburchill and @Courbet had decided to tackle it at the same time! I will say it is 95% true to the original creation.. I only needed to change a few minor things - I added a Clutch gear in, just before the pot-stirrer, as I had a couple of times where balls jammed in there I also believe that I don't have something right, as the 'shutter' rising up and down the picker column, hits the output chute from the ball input.. it touches it slightly.. but so far, doesn't seem to affect the machine too much it seems to be quite reliable too - 1 ball dropped every few hundred, maybe? and sometimes, it doesn't pick up a ball.. but the next arm around will get it, and any build-up of balls will be cleared very quickly the input bin doesn't seem to like a full dump of 30 balls.. but is fine with 10-20 in there I also took this opportunity to have a good play with Bricklink's Stud.io editor.. and have enjoyed using it.. Therefore, there is now a digital file of this GBC: Stud.io Format: http://bricksafe.com/files/rbeckett/gbc-stuff/eggprocessgbc/GBC Egg Process Machine.io LDraw: (export from Stud.io - hope it's OK!) http://bricksafe.com/files/rbeckett/gbc-stuff/eggprocessgbc/GBC Egg Process Machine.ldr @Courbet has generously offered to create instructions for this - so hopefully he will add to this thread, when done! :) Stud.io reports that this model uses 635 bricks, and apparently will cost $75USD to build! I should probably buy a few Angry Birds Lego sets to decorate it!!! :D
  15. After my Rainbow Wave it was time for something different. Inspired by the Paternoster in the Wall-E movie I wanted to create something like that as a LEGO GBC. I kept the in box as low as possible for reasons I will reveal later. As a result of that the ball pickup after the ball release from the buckets is just 1 brick high. Hope you like it:
  16. Great Ball Pit

    [GBC] Multipath

    Hello, here is my latest module which will allow me to split the flow of balls into two separate outputs. I've wanted to do a path splitter for a while. So after seeing a module in a recent European GBC layout that used the Sports ramps in this manner, it inspired me to get started. This module has a recirculation function, massive input bin, and the ability to move balls out quite quickly. The biggest challenge when building this module was getting the sweeper motion to work as intended. If anyone here has a better solution for the sweeper linkage please leave a reply as it is something I'd like to improve.
  17. This lego GBC module uses three cardan gear mechanisms to rotate the platforms that the balls sit on. It is a reliable module when you have the timing between the loading and unloading mechanisms aligned right. The long technic axle you can see running through the front of the module is how it shares power between it and other modules. I am trying to make all my new modules able to share power in this way, as this way I only need one motor for every 4 to 5 modules. If you wan to build this module I have instructions on Rebrickable. More photos on Flickr. The mechanism to load the balls is quite simple, although it is not the most smooth. I would like to change the mechanism to something easier on the parts, maybe by making the main stepper tall enough to let the balls roll straight on. The unloading mechanism is inspired by Akiyuki's mechanism, although it is not exactly the same. This version uses the 2L rubber technic beams instead of rubber bands, and holds two balls instead on one.
  18. I came up with the mechanism for this module by accident when I went to put a axle through the middle of the gear, and thought "I wonder why I have never used the other axle holes for anything" and that is how this module started. The mechanism quite reliable, as long as you have the timing between the two parts of the module is right. The timing is easy to set up by holding back the last gear while the mdoule is running. Instructions are on Rebrickable here. I know that I am still using non-lego balls. Yesterday I went to buy them from lego bricks and pieces, I added them to my bag and then went to add the lego hogwarts express set to my bag as well. In the time that it took me to do that they went out of stock, hopefully they will be back in stock in the next few days. More photos.
  19. I've designed and build this LEGO Great Ball Contraption for Lego World 2017 in Utrecht in The Netherlands. Last year almost over 100.000 Lego fans visited Lego World. This GBC will be part of a circle of over 150 machines. The kids control the Ball Catcher Mouse with LEGO power functions and are thus responsible to keep all balls circulating as part of the 150+ machines. I hope that is exciting enough for them :) http://www.youtube.com/watch?v=s1ZZsKZlan4
  20. This is my take on Tom Atkinsons‘s „Perpetual Prototype“ module in classic GBC style. Often seen in Beyond the Brick GBC videos,
  21. This is my latest version of my very first Great Ball Contraption module - the simple tipper. I have made a video showing the details and how it can be combined in a circuit of similar modules with bridges and common motors: HISTORY The first version was quickly made to a competition in my LUG back in 2007 The deadline was coming up and I did not have a video camera. The pictures (see them cut together in the video) were taking using one of those $20 'stick' digicams that were popular back in the early 2000's. The module was shined up for LEGO Fan Weekend in Skærbæk, 2007: The theme was Aquanauts, but this is unfortunately the best picture I have of it. I brought this and the green 'Logo Roco' module to the event. The other module had a tendency to tear itself apart due to being built using normal bricks and having a hammer to shoot the balls up - similar to the gameplay of the game Loco Roco. The next version of the module had the normal bricks replaced with Technic, the blue rails replaced with a tile and is much more open, making the balls easier to follow: Unfortunately lifting the ramp caused the motor to wear out prematurely, and the outbox was not easy to align with other modules. You can see it in action in the first video, and in this at 6:45: IMPROVEMENTS The latest module has a counterweight in the inbox to reduce wear on the motor The outbox is now to the side to avoid the moving outbox alignment issue: BUILDING INSTRUCTIONS For this reason there are also two building instructions: One for the outbox left and one for outbox right: Left: https://brickhub.org/i/445 Right: https://brickhub.org/i/446 MOTORIZATION The module can be powered by both an M or an L-motor The motor can be mounted both in the middle and at the sides (see the video for how) FUNCTIONS The inbox is 'antagonized' by moving back and forth: And the module is fairly open to make it easier to follow the balls move through: The holes in the ends can be used to connect other modules of the same kind using pins: You can use bridges to make things more interesting, and common rail motorization to reduce the amount of motors required: This will be my last 'simple' module for a while. My plans are to make a couple of really interesting ones for the upcoming LEGO event in Fürth. Take care, and remember if you follow the building instructions: Colors are not important in GBC!
  22. I've designed the below GBC called Rainbow Wave. It has 38 Lego colors and about 1150 moving parts. It is powered by a single motor, with each of the colored pistons sitting on an 8-tooth gear. Each piston’s gear is exactly 1 tooth offset from its neighbors making one wave 8 colors. The GBC is level so the balls are moved by the waving surface. Free building instruction for version 2 and parts list is available on Rebrickable with a thank you @Courbet for the improvements and creating the digital model! https://rebrickable.com/mocs/MOC-7456/Berthil/rainbow-wave-gbc-v2/

    [GBC] Upslide

    I forgot to post this last week, here's my latest module Upslide. It uses a helical pusher to push balls up a friends slide, and it's powered by a PF M Motor. I tried to run it at BrickCan this weekend, but it only performed for a few hours before having a bunch of issues I'll need to fix. I need to reinforce the input bin walls, tweak the output at the top of the slide, and fix a small gearing issue for the helical drive. Stay tuned for a version 2.

    [GBC] Old Town Road

    Here is a GBC module built using a conveyor, and the older "Racer" track. The theme is based on the song of the same name. The conveyor is powered by a PF-M Motor, and the Sweeper is using a PF-XL motor.
  25. I’m really excited and happy to share with you the first video from Planet GBC, taking the form of an online magazine.
