  1. 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!
  2. 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.
  5. I’m really excited and happy to share with you the first video from Planet GBC, taking the form of an online magazine. In the video, you will: → Discover GBC → Have an overview of the best GBC modules released over the past weeks → Learn how to build a GBC module from A to Z (get the instructions, buy and order parts you need) and reproduce Sawyer Scissor Lift module → Find and buy GBC balls for your module I hope you will enjoy this video. Don't hesitate to leave comments on this video via this forum thread
  6. After buying two bucket wheel excavators for parts I had to do something with the Rings and Buckets.So I designed and build this GBC. It rests on 4 wheels and all 4 wheels are powered. This GBC has very tight tolerances almost everywhere.

    [MOC] Scrooge McDuck's Money Bin [GBC]

    When I saw the Scrooge McDuck mini-fig in the Disney CMF2 I knew what I had to build as my next GBC module! I present to you Scrooge McDucks Money Bin, which is loosely based on the vault seen in the Ducktales cartoon. It's built primarily with white and bright green brick, I used flame orange for the $ on the front of the building. The build was a little bit different then most GBC builds. Usually in GBC you build the lift mechanism first, but this time I built the structure first. I then built the conveyor and fitted in in the back. The last part of the build was getting the recirculation feature working inside the "chute" the balls fall through. I hope you enjoy the build !
  8. Lego GBC Bucket Conveyor Module This Lego GBC module uses a conveyor mechanism with the buckets from the bucket wheel excavator set attached to it. It is a slow but reliable module, and it can (surprisingly) hold the GBC standard of 30 balls. The yellow rail you can see in the back is part of the mechanism that keeps the buckets at the correct angle. It works well but I would like to change it to use small technic wheels to reduce friction on the mechanism and make the parts last longer. The ldd file and instructions are of rebrickable here. The two gray 6L half beams help to stop the buckets from catching on the bottom of the module. I am not using clutch gears in the video but I have tested it with them. It would probably be a good idea to use them, the module ripped itself apart several times throughout the build and testing process. More photos on Flickr.
  9. Hi. I’m a long term Lego fan but only just getting into GBC and need some help. I want to build one of Akiyuki’s modules (strain wave gearing) and not that there are instructions and a link to a bsx parts list. I have successfully managed to take xml format parts lists and copy/paste into BrickLink to manage parts buying under my wanted lists but I don’t know how to use BSX? I have researched that I need brickstore/brickstock or possibly Rebrickable but when I click on “parts list” link in eurobricks it opens a new web page with the bsx text and seemingly no way to save down or export this other than copy and paste the text. My question therefore is this: how do I export or utilise the eurobricks parts list (which states bsx forms) into either brickstock/brickstore or Rebrickable in order to be able to create and import an actual .bsx file into BrickLink? Sorry if this question seems stupid but I’m really struggling to find any guidance for this seemingly simple task and would greatly appreciate the help. Otherwise I’m stuck manually looking at the pictures parts list page at back of instructions and manually finding the parts one by one in BrickLink which is easy and doable but naturally takes A LONG time. Thanks in advance for any help on this. James
  10. Update from 2019 I have made a new and stable version of the GBC module for which there are building instructions: The new module has a latch and lifting counterweight mechanism to make the tipper function reliable. The building instructions can be found here: https://brickhub.org/i/425 The tipper fills up: The counter weight lifts until the latch comes undone and the tipper tips: And empties: Closeup of the latch mechanism, which doubles as a stop mechanism for balls, so they do not fall onto the tipping tipper: The module can be placed in self-feeding mode, just like the old module from 2008: And circuit mode: In the back side there are skirts to catch potential escapees: Rendering of the model from the building instructions: See the brickshelf folder for "action shots" where series of pictures are taken in succession to show the functions: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=315097 The initial content below this line ------------------------------------------------------------------------------------------------------------------------------- It has been a long time since I have presented a new MOC in here. I have been busy preparing for Klodsfest 2008 in Taastrup. Here is my contribution to the GBC-layout. (Those space ships are made by Sir Bugge from Classic Space forum - the red Z-fighter is new and contains some superb building- and SNOT techniques. The white tower is also a GBC module and the builder brought enough extra modules to complete a circuit) The big ring lifts the balls up and it's random whether they fall through the first or last hole. The first leads directly to the glass tower while the last guides the balls into the deer scarer (Shishi odoshi in Japanese). I don't have a video camera, but I was able to make this little movie using my regular camera: http://www.youtube.com/watch?v=CQ00fXpgQOs The module has a self-feeding mechanism so it can work alone and is remarkably reliable. Anyone who has seen my previous modules would be surprised. If the wheel gets blocked, the big PF motor will try to budge it free. It drops a ball now and then - that is my trademark
  11. After my experiences at the full week of Lego World Utrecht I decided to do a complete redesign and rebuild of my stand alone GBC version of the Akiyuki based marble run. Only the method of clamping the tubes as tracks is the same as in the previous version. The ball shooter had proven it's reliability during Lego World and because of the improved design only one shooter is used. Very pleased with the now reliable result. https://www.youtube.com/watch?v=olx4JmtnVq4
  12. Technic Master

    Hello Everyone!

    Hi All! Long time lurker first time poster! Happy to have joined the community! Im an avid lego fan (albeit a bit of a lego hoarder) and I have been collecting lego since the 90s. I really enjoy working with the technic theme theme, creating random machines and creating GBCs, however working with classic bricks also works for me. I have approximately 100k pieces available at disposal (mostly sourced from bricklink), which is probably not as much as what you guys have :) I’ve also recently started a youtube channel to share some of my creations, please have a look and subscribe! Technic Master’s Youtube Channel Looking forward to sharing more of my custom creations. Louie
  13. I took sawyer's Spiral Lift to a higher level xD Sawyer's thread 7 levels and Akiyuki style and input.
  14. This Lego GBC Module uses a Scissor Lift mechanism to lift the balls up. The mechanism is quite reliable and sturdy, I never had problems with the balls falling out. The gear train is long but it does not have much friction because the stepper does not use much power. I would like to make one with more lift mechanisms similar to Akiyuki's six heads module but I don't enough of the cup pieces. The LDD file is here. More photos here.
  15. GBC 25 Sweeper This is a slightly different review than normal. This is not a set review; it's an instructions review. PV Productions publishes a line of GBC instructions, made from existing Lego sets. This makes it very simple for new GBC builders, since you don't have to hunt down an array of parts via Bricklink. If you have one of the Technic sets, you have everything you need. Name: GBC 25 Sweeper Set Number: uses parts from 42049, Technic Mine Loader (originally retailed for $50; currently used sets are available for $30-40 on Bricklink) Pieces: n/a Price: €9.95 for the instructions Minifigs: 0 Theme: Technic, GBC I (and my sons) love watching GBC setups. The mechanisms used are fantastic and just fun to watch. I've seen the massive discussion threads in the Technic forum here recreating Akiyuki and other GBC designs. One drawback is the need to assemble an array of pieces, and there's often the need for rare pieces (like the chrome silver reflector dish that's beloved in GBC setups and so sells for multiple dollars EACH). PV Productions publishes a line of GBC instructions, where each design is a "C model" of an existing Technic set. As long as you have that set, you have all the pieces you need to build the GBC (except for the balls, which PV Productions also sells compatible, non-Lego balls). I bought a couple instruction sets to convert Technic sets I own into GBC modules. I did not buy the PV Productions balls - I didn't want to pay international shipping. After some googling for alternatives, I saw recommendations for 9/16" Delrin bearings. I ordered a bag of 100 of them on Amazon for $11.25 shipped. The Instructions PV Productions provides their instructions as downloadable PDF files. They are designed to be printable, but that would be costly, since they have the solid light blue backgrounds like many Lego sets do. Instead, you can easily use a computer or tablet to view it electronically. The files are password protected and have your account information (email, purchase date) across the bottom of each page to prevent piracy. Given that, I don't know why they restrict you to 3 downloads of each file. It seems like an unnecessary complication to the process and would cause extra customer support issues to arise. The instructions are reasonably easy to follow. The image quality is slightly less than Lego and occasionally the steps are difficult. It's obvious that they're generated by computer rather than hand-curated. Some steps aren't turned the best way to view the connections being made, and some steps would be easier to do in a different order. None are TOO difficult, so it's not too much of an issue. It is definitely a significant step up in difficulty though - not for small kids or someone who hasn't done much Technic building. Personally, I liked it. I'm a fan of the older instructions that added more pieces at once and were more complex. The current instruction style feels over-simplified to me. The GBC This GBC is designed to look like a trailer. There are wheels and a tow point at the front. However, it's not really usable as a trailer. The wheels are attached to pins, not axles, so they don't roll easily. That could be modified if you wanted; there's axles left over. And when you are operating it, there's a tool to lock the wheel in place (it's the assembly with the dark grey axle connector just above and to the right of the tire in this photo. The light grey axle goes through the pinhole in the wheel and into the frame of the GBC to keep it from rolling) There's also a few spots that feel like part usage just to use up pieces - such as the "light" made of a stack of clear studs on the upper edge. PV Productions also followed the Technic standard of including a piston engine in the set. In this case it's a tiny single cylinder design, but it works. It is pretty fragile and fiddly during the build process though. At the front, there is this axle with a pair of light grey 3L perpendicular connectors on it. It can rotate, flipping the connectors up. The only purpose I see is that adjusts the angle of the GBC by the tiniest of amounts. The feed tray for the balls is connected by this single point. That does make it wobble around, but that also is part of how it works. I have a feeling that if it was more rigidly attached, you'd have more ball feeding issues. The right-side tire is held out from the machine by this red bush. That is because it'd rub on he yellow liftarm if it wasn't out so far. That does make it feel a little unstable though. Since you can't really roll the unit around anyway, I removed that red bush on my setup to make it a bit more compact and stable. The Video This GBC runs very smoothly most of the time. If you don't put enough balls in, it does sometimes mis-feed and the ball not drop under the "antenna" piece. With 5 or so balls, it runs great. The manual does walk you though how to get the timing right of the lifting mechanism, but I found that if you just position them as shown in each step of assembly, it comes out working right. If you weren't paying that much attention to detail, you just need to remove the black gears, rotate each tan gear correctly, and put the black gears back on. The video also demonstrates the other party trick of the set. If you rotate the exhaust piece at the top of the path, the balls fall straight ahead, making it able to feed into a different GBC instead of returning them. The Conclusion This is a great introductory GBC set. It's easy to get the parts for, since it's all from one set. It runs well, and is a nice level of challenge to assemble. I think it makes a nice display on its own, but there's also room to modify it if you want. You could make it longer, improve the return ramp, etc, and that's part of the fun of GBC. The price seems reasonable on it's own, but when I look at the other, much larger, GBC designs that they sell, in comparison it feels a touch overpriced. This small set was ten euros, but instructions for much larger models are 13 to 25 euros. Given how much work must go into designing and then digitally modeling each set, none of it seems unreasonable. Now time for me to go work on the GBC 14 Strandbeest, built from the 42054 Tractor set...
  16. This lego GBC module use 3 brick separators to lift the balls up. I came up with the idea to use them like this after looking at a pile of them that I have and thinking that having more than 2 of them is kind of pointless. The module is quite reliable and in in theory could be made much higher easily. The loading mechanism is designed so that the ball can role back into the module if it does not role onto the brick separator properly, this happens sometimes when the batteries run low. (you can see at 0:46 in the video) The LDD file is here. More photos here.

    [GBC] Separation Anxiety

    Hey everyone, here is a sideways conveyor I've made using 25 brick separators. It is quite a simple build, and has some input restrictions. It can handle a fast stream of 1-2 balls but would fail the 30 batch standard rule. I think it looks great even when turned off. Some people have said it looks like an insect, and I think it has that nice baggage carousel effect when it's turned on. Please enjoy the video.
  18. Hello, I present you my "washing machine" Two drums turn in opposite directions, inside each of them there are guides to advance the balls. In the 2nd there are small skips that go up the balls until the exit. The two drums rotate on tires then allows sufficient grip and allow stalls in case of jamming ball. This also makes it possible, compared to the sprockets, not to synchronize the rotation of the two rows of tires. The frame is rigid to hold the two drums in place.

    [GBC] Solaire

    Hey everyone, Here is a very simple, yet elegant GBC module using the old Skateboard Ramps, and the newer large ring gears. It clears balls very quickly, and is rock solid reliable.
  20. This lego great ball contraption miniloop uses a ball pump style mechanism to lift the balls up, when they reach the top they fall out of the "lighthouse" down onto the rocks and back to the start again. The mechanism is quite reliable and can be made as tall as you want, if it is built higher it might need extra weights to make up for the weight of the balls though. (I am considering using it for the start of my next module). LDD file.
  21. This lego great ball contraption module uses technic "banana" gear to lift the balls up. It does put a bit of stress on the parts but it doesn't leave any damage. They are at a bit more of a angle than Maico Arts original version wich was 1.5 studs apart, this way it can be higher and run smoother. The stepper mechanism uses two lift arms on each step, this helps it run smoother and with less force on the motor. The LDD file is here.
  22. This lego great ball contraption uses a shooter mechanism to shoot the marbles into a castle. The range of the shooter mechanism can be easily adjusted with a gear at the back, it uses a large linear actuator attached to a shock absorber to do so. Part of the back of the castle is made from lego 6L half beams to slow the balls down. I have the LDD file for this module here. Do you like this kind of decorated module or do you think it is better to just focus on the functions? I like this kind but it uses a lot more pieces and takes a lot longer to build.
  23. Update 2 New, more reliable, version of the module is up. The GBC layout now contains 20 modules. See my latest message below. Update The module has been updated with an anti-jamming mechanism. See the updated building instructions on http://c-mt.dk and Rebrickable (http://rebrickable.com/mocs/MOC-8843/LasseD/gcb-conveyor-starter-module/). See my latest post for the process of testing and improving the module. It is about time I did my part for getting new members on board the Great Ball Contraption (GBC) train. Here is my starter module. It is a simple conveyor module with 194 parts where none of the parts should be hard to come by. Here are the building instructions: http://c-mt.dk/instructions/models_gbc-GBCStarterConveyerBelt.htm In the video I also show how the module works in a circuit. This module should be easy to multiply where a single motor powers multiple modules. I will try to do that next.
  24. I'm back with another module and video. This time I've created a small, simple conveyor belt that is proving to be quite reliable. As well I've shown how you can modify it to make it your own creation. Instructions for this module are available on my website. Here is another version I've made. I'll be posting the video for this one next week. Here is the video for the Jade Dragon variant.

    [GBC] Hailfire Loops

    So what do you build, when you have 4 Hailfire wheels? an oversized GBC module! I had an idea to build this a while ago, and finally finished it for Brickvention 2018, in January. However, it wasn't reliable enough, and ended up needing 2 motors to drive it. I recently rebuild the main geartain, using better parts, and working hard to get rid of all friction points. It now runs MUCH better, on a single L Motor. Front loader section is an Akiyuki design, from Cycloidal Drive. The rest, including the Brick Separator down-chute is my design. Due to the design, I was not able to use the inner teeth to drive the wheels... as the scoop would interfere.. so I had to drive it by the outer rim This has been done in the past, by other builders, using tyres. Somewhere along the line, I noticed that the old Samsonite gears from 1965 meshed perfectly! (The Expert Builder ones do not) I attempted to have the stepper/loader synchronised to the wheel, but unfortunately, I was not able to get any combination of Hailfire external teeth + Samsonsite to equal an even/repetitive interval. Turns out that it takes 7 revolutions of the Hailfire, before the same tooth on the Samsonite match up again! So.. that does mean, that occasionally, it'll feed in a ball at exactly the same time a scoop passes... and while most of the time, it bounces back into the main wheel.. sometimes, it bounces back, and spills. There is a small collection point for such spilt balls The Scoops are a simple build, and are held in place via friction the Hailfire wheels are supported by 1L liftarms on an axle, and there are 4 rubber wheels at N/S/E/W, that the Hailfire leans against, to run smoothly The drive-train feeds up and down each module - with the motor attached at Blue, since it's at the mid-point.. At the bottom of yellow, it connects to the front loader section. And since it's SO big, I needed to build it modularly! So it all comes apart easily! Looking forward to running this improved version at Canberra BrickExpo next month! Oh.. and apart from the depth.. it is actually GBC standard! :)
