We are here to pump you up. Presenting a simple ball pump GBC module. LEGO GBC Ball Pump Module by dr_spock_888, on Flickr YouTube video: (no music to avoid DRM issues in some regions) Enjoy. -
Hi everyone, Of all the things made with Lego, my favorites are inevitably the Great Ball Contraptions. GBCs, as they are known for short, are Rube Goldberg-style machines designed with the sole purpose of moving tiny balls through a circuit. The GBC is an elegant ballet of Lego, and the ultimate contruction feat of these balls as well as their robotic NXT counterparts. The mechanisms that move the balls through the loop are generally as complex as possible, using clever actions that are reminiscent of the workings of a factory right out of How It’s Made. I think, the Great Ball Contraption is just about the greatest feat of Lego engineering that there is. So I mostly make LEGO GBCs with in particular GBC-plans with more modules mixed in one big great ball contraption. I only publish the final videos on youtube. So subscribe if you don't want to miss anything. For interim updates you must visit my facebookpage or my website. So make sure to check them out as well!

GBC: Lego balls vs Chinese beads
dr_spock posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
My eBay order of 14mm beads arrived in the mail from China today. Big thanks to EyesOnly for providing the eBay link. They costed about $5 USD. Since I have a few Lego balls, I thought I do a comparison. Here is a picture of the recent Lego balls from Friends sets and the Chinese bead on the right. As you can see the bead is shinier and smoother than the Lego balls. Also the bead has a bigger hole that goes all the way through for the strings. The hole in the Lego balls do not go all the way through, therefore, you can't make a necklace or bracelet out of them without drilling. With the bigger hole there is probably less mass. I weighed 8 Lego balls and 8 beads. 8 Lego balls = 12 grams 8 beads = 11 grams The slight weight difference didn't seem to cause a problem with my ball accelerator module since I am not flinging the beads that far. GBCs that shoot long distance may need some testing and adjustments. There is also a size difference with the beads. They don't have the exact size consistence as Lego when measured with a caliper. Lego ball = 14.07 mm beads = 13.5 to 13.7 mm In general, they seem to work well with my 4 GBC modules. One issue I found with the bigger hole is it can create a flat spot that the beads can't roll over if it doesn't have enough momentum. Some of my GBCs uses incline with gravity to feed and the beads some times get stuck until another bead knock it loose or I manually free them. Summary. At 5 cents USD each, they are a bargain compared to Lego balls. They are lighter than Lego balls and the bigger hole can cause the balls to get stuck on the path. So more 'babysitting' of the GBC module may be required. Overall, I think they are great for doing public display of GBCs where balls tend to get lost throughout the day. -

LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
After the success of my previous GBC Counter module, I decided to upgrade the app and also release it to the public along with a detailed tutorial for building your own GBC counter. How it works explained here: http://www.eurobricks.com/forum/index.php?showtopic=83844 The app & module support the GBC standard of 1 bps. New features: -Balls per second display -The new app & module can handel more bps than the first version -GBC timer -Better design Tutorial download (includes a PDF file, LDD file and the app itself) http://www.mediafire.com/download/wmfxy3ny1rbdrtc/GBC_Counter_Tutorial.rar The video: Thanks for watching! -

GBC - Balls and sets where to start?
DS613 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I am afol and I own a few lego sets, and I am very interested in starting GBC bulds but I dont really know where to start. Any help would be nice. What sets to buy to get started with GBC builds? where to get the basket and football balls? where to get the gears? where to get the power? Web sites etc. Thanks in Advance DS -
GBC Marble Pump - Version 3
LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi! I made a new GBC module. This one wasn't aimed to be complex or very clever - It was aimed to be simple and easy to operate. I built it because many people on youtube asked me for a simple,not motorized GBC module,and only uses common Lego pieces. It's very fun to operate as you only need to press a button and the ball elevates,unlike previous marble pumps which were hard to operate by hand. I think that the video & description provide enough info...so...here's the video (there is also a LDD file in the description) -
GBC Module - Drag & Tilt (Fixed Video)
LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
My new GBC Module(s). These are actually two modules working together,both using the same motor. The tricky part was to sync everything up - making the motor switch the cart direction just when it reaches it's extreme. Everything stays in sync without any drift (tested for ~2 hours,stays in perfect sync) The motor always spins in the same direction. Here's the video Thanks for watching! (It's very hard to name GBC modules ) -
GBC Ball Counter Module
LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello! I had this idea of making a ball counter for a long time,however,I don't own an NXT and neither have enough pieces (and the knowledge) to build a mechanical one (like Nico71's) So after some work I came out with this - I've built an app for my Nexus 4,which uses the phone's built in proximity sensor to detect proximity change. The app then adds one to the ball counter,and waits 700ms before measuring again (because of the lever sometimes jumping a little after it moves) The first prototype was a rail going in front of the proximity sensor,so every time a ball crosses it will block it. This,however,wasn't reliable at all because of the sensor's low refresh rate. So I built what you see in the video - now,a ball goes up in a threads lift,moving a lever which then blocks the proximity sensor. It's 100% accurate. Here's the video,thanks for watching! -
GBC Loop 3 : 4 Modules
LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello! I completed my 3rd GBC layout. It has 4 modules: Accelerator,Mini Ferris Wheel, Up & Scissors lift It required all the pieces I have (and some improvising,like the long axle used in the Accelerator module because its motor's cable didn't make it to the battery) Anyway...Here's the video: Thanks for watching -
LEGO GBC Module - Mechnical Chain
nxtstep101 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Here is my latest GBC module! It was inspired by . It was rather simple to build, but the turning mechanism took me awhile to figure out.Here is a short video I made: I am almost finished with my GBC layout, so be looking for a post about it soon! I just noticed I accidentally spelled "Mechanical" wrong in the title, sorry. -
GBC Module - Scissors Lift
LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
My very own GBC module It uses a single M Motor to elevate (and lower) the platform. There is a small 'gate' on the platform blocking the balls from falling until the platform reaches its highest point. There is another gate on the ball input to make sure the balls dont fall to the ground,only to the platform. The platform can carry about 5 balls at once. Here is the video Thanks for watching -
GBC Module - Mini Ferris Wheel
LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Inspired by nxtstep101's ferris wheel,I thought I should build my own. Mine,however,is very different from the original:only the concept (of spinning axles which carry the balls up) is the same :) The video: Thanks for watching. -
GBC Module - Accelerator
LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello I made a new GBC Module. Its a pretty simple one which will be used to bridge between the end of my GBC loop and the beginning ,with low part count. The runway in this video is only temporary in order to demonstrate the module. Thanks for watching. -
GBC Module- Clicker
LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello :) After a lot of time I didn't have time to build,Iv'e finally found the time to build some GBC. So I built this module..named it clicker (because when the balls switch between levers there is a click. cant be heard in the video,tough) There are 2 issues with this module: 1) it cant take more than 2 balls at once at the queue so I need to build a seperator for it. 2) This module took 90% of the liftarms I have,because I don't have any other technic set rather than my 8043. I think the video explains the rest. Thanks for watching. (Sorry for the shaky camera) -
GBC module: Ring with deer scarer
Lasse D posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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
