  1. Our big yearly Lego convention here in Melbourne Australia, was on last weekend, and we managed to put on a pretty good GBC layout Thanks to @rasikaa this year for coordinating it! Here are a few videos: My video, on Sunday Saturday: (most modules running - 111) @9v system's Akiyuki-only layout: Everyone else in the team, incl @Captainowie, @Cadder and others did a great job keeping everything running so well... We only had 76 modules last year, and the jump to over 100, especially with so many brand new modules, is a lot of work! I was happy that a couple of new ones of mine (eventually) worked really well.. and I'll probably do a separate post on them all
  2. Hey guys, Since completing work on my Tri-Sep module, I've completed what I'm calling the Greyline Series of modules. This series includes: Greylime, Reservoir, Bucket Boost, and Tri-Sep. It is all running off of two 9 Volt Train Controllers. Please enjoy the video. Individual videos for these modules are available on my channel, the Bucket Boost video will be released later this month. It is the most complicated module I've made.
  3. Greetings all. I've recently been playing with Stud.io, and teaching myself how to create instruction .PDFs using LPub with the intention of modelling/creating instructions for some of the GBC Modules I have (physically) built, both MOCs and Mods. To start off while learning, I used something that 's quick to build and only uses a small number of parts. So I present Cadder's "Found Ball Bucket". Backstory: This is a little something I knocked together while displaying at Brickvention 2017 and fine-tuned at BrisBricks 2017. Originally it was a 'catcher' that I made for a high module displayed at BV2016, essentially because I had 4 spare Lego Sports arena corner units... but it quickly became more useful. Occasionally at GBC shows, a rogue ball will "escape" and be picked up by young kiddie spectators who will invariably try to reach across the displays with an ever-helpful "'Scuse me mister! I found this!" Rather than risk knocking over or bumping/misaligning the working GBC modules, it became really handy to reply "Awesome! drop it into the blue bucket!" This had the great side-effect that it engaged said kiddies.. and with an added "See if you can make it spin...", makes the GBC display somewhat interactive. It's also versatile enough that it can be placed pretty much anywhere on the GBC circuit and feed found balls back into the circuit without too much disruption. It's deliberately built high enough that the return chute is higher than the 10-brick standard GBC input size. Returned balls should just drop straight into any module's Inbox. I dare say it could be double-purposed for its original use as a catcher - for, for example, a tower drop, shooter or flicker module. So. At first I really wasn't sure where to post this, and although not strictly a GBC module itself, it *IS* a very handy tool (I've subsequently built more than one) for GBC displays that I hope other GBC organisers/displayers might like to adopt. I also intend making a sign to stick on the front, something akin to the "Hey!" logo on the back of the City boxes. (ie, Along the mines of "Hey! Find an escaped GBC ball? Drop it in here!") Instructions in form of PDF file here. Also, because it was modelled in Stud.io, you can use Bricklink's Step view builder instructions here. (and buy parts) cheers!
  4. Hi. With the quality of entries I've seen so far, I don't like my chances of winning, but it would be nice to get a badge! I'm going to use this contest as an excuse to redo a previous model of mine - a GBC module powered by pneumatics. This is what the old version looked like: I have used it in a previous display, but it has numerous shortcomings as a GBC module. The output is not in line with the input, violating the spec. It was what I needed at the time, but it's not suitable for general use. The output is impolitely high. Again, it was what I needed at the time, but I couldn't put this into a normal circuit. It would frequently jam. It spilled lots of balls. I will be using the same sequencing (basically the simplest alternating sequence possible). I had toyed with the idea of something more complicated, but 1) I couldn't get my head around how to make the sequence I wanted, and 2) it would have been too slow anyway. I probably won't make a compressor for this one, leaving it hand-operated. The idea being that in a display it can be somewhat interactive - the audience gets to power the Contraption (or at least some portion of it). Best of luck to all entrants! Owen.
  5. For Brickfete 2016 and the Friends contest, I made a Friends-ly tree slide GBC module. The input and output are to GBC standards so it should play nice with other GBC modules. During the event I had make various modifications and fixes. Although, it worked great at home. I think I got the bugs out of it now. It had pretty good response and feedback from girls and moms.

  6. Back in 2013, I built and posted about my first NXT ball machine (you can view the original post at http://www.eurobrick...topic=87788&hl= if you are interested). While that machine worked, I learned a lot while building it, so I wanted to create an entirely new machine that incorporated what I learned. I also wanted to make it bigger. Now, in 2015, I have completed my second NXT ball machine. This one is almost 6 feet tall, and over 7 feet wide. The longest span is over 4 feet. It uses simpler lift mechanisms that are more reliable (though they do still jam occasionally -- I have an idea about how to fix that which I am planning to incorporate if I ever build a third one). This machine is also much less sensitive to how level the surface is that it is sitting on. As a result, this machine is a lot nicer to set up and display at a show. It is also much more open, giving people a better view of the balls as they move through the machine. Here's a YouTube video showing the machine in action: There are two possible paths through the machine. The path splits at the top of the left tower with some balls following the gray track that crosses the width of the machine several times. The other half of the balls follow the silver track that spirals down the left tower. Let me know what you think! Ben
  7. Hello Eurobricks, I'd like to present you with a collaborative build that I made with BrickJunky for Brickworld Chicago. The idea was to present our interpretation of a themed GBC (Great Ball Contraption), though this build does not follow the established standards for a GBC. For those unfamiliar, a Great Ball Contraption is essentially a machine that moves balls from one place to another in creative ways. We were incredibly honored to be nominated for Best Mechanical build at Brickworld and I'd like to thank everyone who came up and talked to us at the event. It was my first Brickworld and I was blown away by the support from everybody! In particular I'd like to thank Steve Hassenplug and everyone from the GBC section for their help and support and we look forward to incorporating a similar build into the actual GBC layout! Be sure to watch the video! Enjoy!
  8. This LEGO ball machine was constructed using 10 motors and thousands of bricks. Its 14 balls move continually through the machine, taking approximately two minutes to complete a lap. Two Mindstorms NXT bricks control the green lift, blue lift and ball counter. A combination of Power Functions and traditional 9V motors drive the remaining lifts. The machine is built entirely from LEGO -- even the balls are LEGO parts. Width: 63.5 inches Depth: 24 inches Height: 30 inches A video showing the machine in action is available on YouTube: Let me know what you think! Ben
  9. 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.
