Hi Everyone. I'd like to show you my GBC Module that I made called "To and Fro". Definition: to and fro /ˌto͞o ən ˈfrəo͝o/ adverb - in a constant movement backward and forward or from side to side. verb - move constantly backward and forward. noun - constant movement backward and forward. I wanted to design a GBC module that I hadn't seen done before. The main feature of this design uses a string and pulley system, with different levels of mechanical advantage implemented to get the timing of the mechanisms just right. This GBC module adheres to Type 1 of the GBC Standards, processing one ball per second on average (http://greatballcontraption.com/wiki/Standard). The main focus of this module is the 'ladder' in the middle which raises and lowers using string and pulleys. You can see this in the video between 1:48 and 2:04, and I'll try to describe what is happening. First of all, the end of the string is attached to the frame, and goes down to the cranks. The exact length of the string can be adjusted, similar to how guitar strings are tightened. The cranks have pulleys on them, so the string actually moves twice as far as the diameter of the cranks as they rotate, but at the same time the force is halved. Next, the string goes up to a pulley fixed on the frame, then down and around another pulley, and back up again. The bottom pulley is attached to the moving part of the 'ladder'. This halves the distance that the 'ladder' moves compared to the string, but also decreases the force required to do so. The string goes over another static pulley at the top, and then back down to the outside edge of the moving part of the 'ladder'. To move the outside edge of the 'ladder' requires the full force of the string to move. Due to the mechanical advantage of the different parts of the pulley system, the 'ladder' wants to move up first since this takes less force, but once it hits a stop at it's upper limit, the string then provides force to the outside edge of the 'ladder' which causes that last little 'kick', which lets the balls roll to the other side. This module can also be broken down into four smaller sections for easier transportation: The motor which is part of my Automatic Motor Shutoff and Alarm System, The 'hopper' and 'ball diverter', The 'ladder', and The 'waterfall'. There is only one M-motor powering this module and that helps ensure the timing of each section is in sync with the next. The motor section is attached to the 'ladder' section with a universal joint, and the 'ladder' section is attached to the 'hopper' section with a CV joint. The 'waterfall' section doesn't need any motor input, so it is attached to the 'ladder' section with a single axle that allows it to be detached easily. Between the 'ladder' section and the 'hopper' section is differential (hidden away underneath), and I can manually adjust the rotation of this differential via a worm gear to get the timing between each section just right. Apart from this one worm gear used to make timing adjustments, I haven't used any other worm gears as I have seen the damage they can do to GBC modules if something gets jammed (although, in theory, my Automatic Motor Shutoff and Alarm System should stop this from happening anyway). There are quite a lot of gears within the drivetrain, but it runs quite smoothly. When I was creating it I thought the weight of the 'ladder' would cause a lot of strain on the motor, but when one side is going up gravity is making the other side go down which cancels out a lot of the strain. Jams sometimes occur in the 'hopper' and 'ball diverter' sections, and are typically caused by too many balls in the hopper, or the timing of 'ball diverter' not being adjusted correctly. I have had this running at a public expo that my LUG held, but I was too busy to baby-sit this module, so it was only running part of the time, but when it was running it ran without issue. This is the first GBC module that I have made, so I spent a lot of time trying to get it working consistently. I hope you like it. Any constructive feedback/comments/questions are welcome. UPDATE: I have created an LDraw/MLCad file of my GBC module. Read more here. Music:

I rarely post but I check this site and other Lego Technic sites like Sariel's and GBC websites and I am stumped on a way to mechanically make this work. I am trying to use the Lego differential in a way that I have not seen others use it, at least in the searches I have performed. Limitations: Input motor needs to constantly run I would like to do this purely mechanically. Cannot use Mindstorms. Would prefer to not use switches unless necessary. Problem: I am trying to use a Lego differential to power two separate sections of my build. I don't have access to easy pictures so please see the simple diagram below. I have power on one axle and the two other axles will drive separate sections. I would like Section A to run constantly (or could potentially stop when Section B is running). Section B is currently being held up by a ratchet that completely stops the gear from turning until it is released, When released, Section B will run one full revolution then stop again until the ratchet is released again. The ratchet release is not on a pattern. It can be released 20 times in a minute then not released again for an hour. The issue that I am running into is that Section B currently has a higher load than Section A; therefore, when Section B's ratchet is released for the gear to run one full revolution, the load is heavier than Section A and Section B does not move. Solutions I can think of: Make the load on Section A larger than that on Section B so that when the ratchet releases, Section B will be easier to move than Section A and the differential will transfer power to Section B and it will work. I would rather not arbitrarily add to Section A's load unless that is the only way. Otherwise, maybe engage a ratchet on Section A to stop that section completely but then disengage exactly after Section B has completed one revolution and at the same time, stop Section B from running. I would think this is more difficult since at least one Section will need to run at a time so the motor and differential don't break but I could be wrong. I'm currently using the 28-tooth differential with 3 - 12-tooth bevel gears (BL: 62821b) inside a 5x7 technic frame Simple diagram: Section B ----------|---------- Section A -----| Differential |----- Input Motor Any help is appreciated. Thanks. -
Lego GBC Ball Batch Module
sawyer klegr posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This great ball contraption module uses I mechanism that holds the balls until there are 13 in it, then the mechanism gets triggered and it started lifting the balls and dumps them into the next module. It is quite a complex mechanism, it works well, as long as it runs at the same speed you set it up for. As far as reliability, it is quite reliable when it is set up to get triggered by 13 balls, and even more reliable when you are ok with 12 or 13. (if you have not guessed by now, this was built for the Great Ball Pit challenge to build a module that only outputs 13 balls at a time) I don't know how log it can run, I have ran it for about 45 minutes and it has not had any problems, but I would not be surprised if it stopped working after a few hours. Hope you like it, there are more photos on flickr here. -
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:

Lego GBC Engine Block Conveyor Module
sawyer klegr posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This lego GBC module uses a conveyor built out of technic engine block pieces to lift the balls. It is powered by a lego XL motor and fully meets the GBC standard, infarct it can actually run reliably at almost twice the required speed for the great ball contraption standard, although it runs more reliably at slower speeds. I originally made this module after chatting with some friends about how we all have so many of the engine block pieces that we almost never use any. This is basically a product of trying to use theme in some way. If you would like to build it I have the free instructions and 3D file on Rebrickable, created in BrickLink Studio. If you have any trouble feel free to contact me and I would be glad to help, hope you like the module! :) Photos on Flickr. Don't know what is happening with the Flickr and YouTube links but they are not working, here is the youtube video. https://youtu.be/nr-HMLtBgqU Lets see if this works..... YES! Not sure what was happening before. -
[GBC] 100% Mechanical/LEGO Ball Counter
Berthil posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
All mechanical and 100% LEGO Ball Counter. Numbers do not always line up perfectly because of backlash in LEGO gears but it counts every ball. I tried to minimize amount of gears but as many of you know, backlash is almost unavoidable. The wheels can be taken out the GBC to set to zero. 1:10 ratio mechanism by Parax77. -
Hello everyone! This is my first post, so comment on any questions and request for GBC modules. Just a few days ago, I was on Rebrickable for a little bit, and thought of finding GBC modules. Well, I wasn't very lucky, because the only one I could find was a back-forth style lift. It was made using the First Responder set. I did not even have that set, as my largest Technic set was Street Bike. I decided to get my Street Motorcycle set, and make this:

Lego GBC Lifting Sprocket Module
sawyer klegr posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Finally finished another one ;) This lego GBC module uses a large Lego technic sprocket on it's side to and lift the balls. It is a reliable module and meets the standard, it can hold over 30 balls in the input bin and runs just over 1 ball per second. The mechanism runs a lot smoother in real life then it look in the video, it also runs a bit better slightly slower. You may notice in the video that sometimes it doesn't pick up the full 6 balls. This could be fixed by changing the agitator design or running it a bit slower so that the balls have more time to roll into the sprocket I did not change the design because it is very reliable like this and still meets the standard.

Lego GBC Mindstorms Robot Arm
sawyer klegr posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This lego GBC module uses the lego Mindstorms EV3 to power the module. It uses a robot arm style mechanism to lift the balls from the previous GBC module to the next one. It is quite reliable and has had almost no issues while I have been testing it. It is quite simple and small for a mindstorms GBC module but it is the first thing that I have ever made and programmed with it. (Do you recommend using the EV3 programming app or Python? I know Python quite well but have not tried using it for mindstorms before) I think it turned out ok for my first MOC using mindstorms, hope to make the next one much more interesting :) Instructions.

Lego GBC and Mindstorms EV3
Hanso posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I am planning to create new GBC modules in the coming years. It will be a combination of Lego Mindstorms and Lego Technic. So not mindblowing mechanical constructions like Akiyuki, but constructions that can only work because they are controlled by the intelligent Mindstorms brick. My first module that I am trying to build (still unsure if I can make it work), is based on the Planar Parallel Mechanism that I saw on Youtube: I find it really cool how it moves. And I thought: let's build this, and use the grabber (visible from time frame 1:23) to pick up balls at the left side of the GBC module and bring them to the right side. Here is an LDD sketch from the first prototype: And a small movie of the first test. The green markers are there, to put the prototype in the start position. That's my major issue right now: how do I now where the four legs of the mechanism are? Working on that now, will keep you posted. Suggestions and compliments are welcome ;-). Regards, Hans aka Mindstorms GBC -
[GBC] Akiyuki compatible stream split module
9v system posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
i have been designing a module that splits the GBC stream into two straight lines. when i was playing with the cup to cup by akiyuki i came up with a good use for that spiral at the start of the module. the idea is the balls roll up then land on a tilting ramp which randomly distributes the balls left or right, but i also included a driving ring so the ramp can be permanently set left or right to use as a turning module. what do you think? -

[GBC] Modular Tipper Module
Lasse D posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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! -
Finally got the instructions finished and you can find them here: ( The instructions PDF will take a few seconds before it starts downloading. Be patient, it will get there. No need to click it multiple times. ) http://www.kanatta.com/GBC/CupToCup/ There is a single set of instructions (PDF), but it comes in two versions. The main version, which uses less common pieces, which are more aesthetically pleasing. Then part lists for a version which uses more common pieces and colours. I have included BSX part lists for both versions and BSX part lists which only contain the pieces needed to upgrade the previous version to this one. The previous version, BSX part list etc. can be found here: The instructions will allow you to create the Cup-to-Cup Type 1 module which you see in Akiyuki event videos from 2013 onwards. I don't think I would have been able to do it without the additional photo provided by Akiyuki and obviously, it builds on the work done by @djm and @Blakbird It is not a faithful copy of Akiyuki's module. The differences are: I changed the hopper so balls won't get stuck behind the spiral lift. I left the support used to get the balls from the lift to the first cup unchanged from the very first version. It works fine, so didn't see the need for a change. The offramp has been redesigned to work with this version. Akiyuki dispensed with the offramp in 2013, using a separate module to do it. The original offramp doesn't work with this version. I tried to keep it similar. Feel free to rework it though. There are some minor changes to the spiral lift to make it work better. It has been good to get this done, as I never liked the motion of original design. Having the motor so far from the cup-to-cup mechanism meant that it wasn't as smooth as you might like. Which is why I think Akiyuki changed it. It is called v1.2 since I class the original grey version as being v1.0 and the yellow version as being v1.1. v1.2 denotes the change in drive mechanism. This has not been event tested. I would advise testing/modifying as required before using at an event over a prolonged period of time. -
[GBC] The Mine - an Interactive Ball Contraption!
RohanBeckett posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
After 2 months of building, here is my latest, biggest, and most complex GBC yet! The Mine I've had an idea in my head for a couple of years now, to build a really solid, fun, and original Human Powered GBC, and this is what I came up with. There are three modes: Fully automatic - where the GBC 'runs itself' Semi Automatic - Humans operate the Detonator, and the Conveyor/Stepper run automatic Fully Manual - One or Two Humans operate both the Detonator, and the Hand Crank Generator. It has a built in bypass lane, so if no one is operating it, balls will continue to flow through to the next module in the layout. Video includes a Behind the Scenes section, as well as a photo diary and commentary of build progress It's been a lot of fun to build (and play with!) and I'm super happy how it came out. It will be shown in public for the first time at Brickvention 2020 in January - Melbourne Australia. -

Lego GBC Conveyor And Stepper Modules With PDF Instructions
sawyer klegr posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
These two lego great ball contraption modules are designed to be simple and reliable so that they can easily be built by new lego gbc builders but still be cool and interesting to watch. I designed these GBC modules to be able to share the power/motor from one module, this means that you can easily power up to about 5-6 great ball contraption modules from one motor. You can also easily use almost any modern lego motor, including Mindstorms and lego powered up motors to power the modules. One of the reasons I built these modules is because I wanted to build some simpler modules that are easy to build. I hope you like it, if you want to build them I have made the Bricklink Studio file, part list and PDF instructions available for free on Rebrickable here: Conveyor || Stepper -
[GBC] Ballkirk Wheel
DaFokka posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The Ballkirk Wheel is a GBC based on the Falkirk Wheel ship lift near Falkirk, Scotland. If you want to see it in action, go straight to the video: Conception I love the concept of GBC and I wanted to build an original GBC module. Ten years ago I got the idea of using the Falkirk wheel. Its continuous mechanism should be just as good at lifting balls as it is at is at lifting ships. Unfortunately back then the inner hole of a large turntable was not large enough to accommodate a 14mm ball plus lane. The only alternative was to use Hailfire Droid wheels but since I was not quite ready to sell a kidney to support my hobby, I dropped the idea. Fast forward ten years and I revisited the idea. @jojoguy10 built a LEGO version of the Falkirk wheel, but noone had made a GBC module out of it yet. The new large studless turntables have no gears in the centre hole, which means that it's (just) large enough to fit through a lane with balls. So I ordered six of them from Bricklink and started building. Building Process When prototyping I tend to use a mix of colors. This limits search time and makes it easier to discern individual bricks. Once a module is finalised, I recreate it in Stud.io so I know how to rebuild it when my BrickLink orders arrive. This is the first time I used a CAD program during the building process. I had no experience with MLCad or LDD and I started out with the newest kid on the block, Stud.io. There are still a few kinks to iron out but I think Stud.io has a great balance of simplicity and power. Gondola orientation The orienting mechanism makes sure that both gondolas stay upright during the entire rotation. This prevents balls and boats from being spilled. The principle is demonstrated by this video: LEGO was actually used by the designers to demonstrate the mechanism for the Fallkirk Wheel. My implementation is very straightforward. The center turntable gear stays stationary. As the wheel revolves, the smaller gears between the center turntable and the outer turntables cancel out the rotation of the gondola, thus keeping it upright: Retarding Mechanism The most challenging part of the build was the intermittent rotation mechanism. The wheel needs to pause shortly to load and unload the balls. Initially, I wanted to use a mechanical solution for this. I have experimented with many different solutions, none of them satisfactory. I started out using a rotating cam that would temporarily block the rotation of the wheel. This did work but it was very imprecise and jerky: In movie projectors and watches something called a Geneva Drive is used, but I did not succeed in creating a version with sufficient angular precision to reliable loading of the balls. Another possibility involves a sliding mechanism on a piston driver, thus first converting rotating motion into intermittent linear motion and then back to intermittent rotating motion. Although motion was smoother than with the cam mechanism or the Geneva drive, it was even less precise and more bulky. Eventually I caved and just used a Mindstorms NXT to drive the wheel. The program is exceedingly simple: Rotate 900 degrees at 80% power Wait for 1500ms Repeat I'd be really interested if someone comes up with a mechanical mechanism, because using software to solve this issue feels like cheating to me. Loading Hopper Since the mechanism completes one cycle every three seconds, on average three balls should be lifted during each cycle to comply with the capacity of 1 ball per second which is required by the standard. For this, a pusher is located at the bottom of the hopper like in Akiyuki's Ball Cleaner. For the mechanism, I took my inspiration from @Lasse D's ball pump. A counterweight on the back of the hopper smooths pusher movement. I currently feel the pusher is the weak point in the contraption. Because it is driven by the same motor as the wheel, it spends half the time not loading any balls, thus limiting capacity. Since 5 balls fit on the piston simultaneously, theoretical maximum capacity is 1.66 balls per second. But when multiple balls are stacked in the hopper, the pusher loads less balls per cycle, limiting capacity. One solution would be to use a second motor to continuously drive the pusher but I prefer the contraption to be driven by a single motor. Controlling Ball Flow The balls move through the wheel because the entire assembly is tilted. The incline is 1 brick per 15 studs, or 1 plate per 5 studs. This corresponds to an angle of 8% or about 5°. The balls should only move when the wheel runs are oriented with the input and output runs. For this both the input run and the gondola runs are equipped with gates that are closed when the wheel is in transit: As usual, the simplest solution turned out to be the most reliable. A sliding gate is held town by gravity. The input gate is opened by two 42610c02 wheels [LINK] mounted at the end of the arms, which sadly are not available in Stud.IO. The output gates are opened by the gears of the orienting mechanism, as illustrated in the following image: Reliability The biggest challenge of a GBC is making it reliable. Those little balls have a mind of their own and tend to find every nook and cranny of your contraption to escape it, jam it or even break it altogether. I tested the contraption with beads with large holes which get stuck easier than the standard balls. The Ballkirk Wheel has gone through several revisions to improve reliability: Incread the incline to prevent balls from stopping in the middle of a run Like 7 versions of the input and output gates Enlarged the hopper and the pusher for greater capacity Several modifications to the pusher to reduce friction and increase reliability Addition of a counterweight to the pusher for smoother operation Added a shield to prevent ball spillage at the exit lane Added a bumper at the foot of the back support to push back balls that have missed the exit Together, these improvements have resulted in a fairly reliable GBC. I have tested the Ballkirk Wheel for an hour of continuous operation with no blockages and only one ball spilled. Maximum throughput is about 1.4 balls per second. Summary Thanks for reading this far, I hope you enjoyed it! Please let me know what you think! I haven't gotten around to creating instructions and I'm not sure I ever will. However, if you'd like to recreate this contraption, you can download the stud.io file: Ballkirk Wheel.io - Stud.io file. -
Hello, here is my last GBC module: IMG_20191215_160937 by alex peraux, sur Flickr Why two steps ? Well nothing to do with an internal combustion engine but simply a module that works in 2 times ... It all started from an idea (not necessarily new) of a carriage lifting the balls. This cart would pick up balls from a basket, go up the slope and empty once at the top. So I started with this part. To make a round trip to the cart there are several technical options (rack, string, chain ...) I opted for the chain. But I did not want a reversal of meaning at the bottom and at the top. The chain must rotate continuously. So I positioned the chain vertically and fixed a Liftarm on it, 2 axel and pin connector to offset the grip and here I am in the axis of the sprockets. This allows a time delay at both ends (the time the Liftarm goes around the spoket). In red the hook with the cart IMG_20191215_171821 by alex peraux, sur Flickr This done, I made the chassis to hold everything. IMG_20191208_190430 by alex peraux, sur Flickr IMG_20191215_161020 by alex peraux, sur Flickr Then the second part loading the basket, a chain with Liftarm will do the trick very well. We place the top of the chain above the basket, a large input tray that can contain several tens of balls and rolls my chicken ( typically French expression ) Well almost, because what happens when the basket tilts and the loading chain is running? Well, the balls fall to the ground: the nightmare. So you have to stop the loading chain when the basket is emptied CQFD( another typically French expression ). This is where the brain is agitated and lays a magnificent removable coupling of a 24T on a worm gear ! The basket in normal position presses 3 liftarms positioned vertically, these liftarms in turn press on the end of a liftarm. This liftarm is attached to 3 studs at its other end and can rotate around this point. At the end an elastic band allows the assembly to remain in the high position when it is not pressed on it. So the basket at rest pressing on the liftarm drives the 24T on the worm gear. When the trolley lifts the basket to load the balls, it no longer presses so the 24T is no longer in contact with the worm gear. I lost you all 2 small explanatory gif (which must be downloaded because flickr does not animate them): accouplement2 by alex peraux, sur Flickr accouplement1 by alex peraux, sur Flickr or in video, the coupling / uncoupling of the 24T on the worm gear (sorry it moves a little) For more photos see my album. And 2 videos for the price of one loading the trolley: and the full video feel free to comment ! Thanks for reading me

[GBC] Egg Process Machine
RohanBeckett posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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 -

I have no doubts that it will shake itself apart at some point. Images and video below. -
Lego GBC Double Gear Module
sawyer klegr posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This lego GBC module uses two gears for the main mechanism, one with 16 teeth and one with 15. This means that the inner gear meshing with the outer one will rotate slowly and in lean from side to side. The balls roll onto the "forks" at the bottom with the use of a timing mechanism which is attached to the main gear. It is a reliable module when it is on a flat table, but it does take some time to set the timing right. I have instructions on Rebrickable here. Hope you like it! -
A new video has been uploaded to our Youtube channel. In 2019, lots of new elements have been added to our layout. To name a few: the warehouse, able to store 60 containers with candies, with two independent stacker cranes, the four candy circles, and an updated delivery station. Also brand new is the PC software that connects everything. We have worked hard to get the software working stable and with success. You can see the result in the video. Enjoy the video! -- Hans
