  1. That is sure to leave some serious damage to the balls at the end of a one or two day display. Hitting the banana gears at high speed will definitely leave some dents on the balls.
  2. [GBC] Brickvention 2018

    @Berthil The Rainbow wave ran well for most of the time and was a heavy modification from the original. The jam in the video was due to some repairs on the ball factory stopping the module just before the video was taken. Both the ball factory and the rainbow wave were on the same controller. Rasika
  3. We use the same product on GBC modules and works like a charm. Best regards Rasika
  4. How about placing a couple of 8 tooth gears around the inside of the banana gears? They are good at giving high torque movement of the gears too. Rather than putting a high load at the center axle, it allows you to move the gear/the central hub much easily. Have used them in a GBC module to rotate two banana gear disks in tandem and works like a charm. BTW, having run GBCs for a couple of years, I can also highly recommend the silicon grease to reduce wear and allow smoother operations. You will need to leave out your purist pride when it comes to practical use. Rasika
  5. Santa needs help

    Hi Luvalot Great to see young kids getting on to GBCs. There are no official LEGO GBC kits as far as I know and there are several people who convert official LEGO sets into GBC modules. There are several threads in here dedicated for GBC discussions and you might find better results by posting in there. However, here are some links that might help you with your quest. http://greatballcontraption.com/ Site which has details about the GBC standard and other stuff. http://www.planet-gbc.com/ Has a very good collection of GBC module details and a good number of them with instructions. It has tags on the side of the blog posts which allow you to easily find the instructions. The instructions are also rated for ease of build which will help you pick. http://www.bricklink.com/v2/main.page is a good site where you can buy selected parts. It is a secondary market place for LEGO. Hope this helps and Santa would be good to your kid. Best regards Rasika
  6. Running in a Loop

    Depending on the layout and the size of the figures, the easiest would be to have a tread link (usually used in excavators) setup sideways and have a Technic liftarm mounted to the stud holes and fix the figure to that. The advantage of this is that you can make the figures go in non-regular paths by cleverly guiding the tread link back and forth using rollers. Rasika
  7. Here is a good start for the mathematics involved. http://robotics.stackexchange.com/questions/344/with-a-6-axis-robot-given-end-effector-position-and-range-of-orientations-how
  8. Ha ha ha... Your modules also had their time. Specially the bucket spinner which constantly had to be helped when a ball got stuck underneath. R.
  9. Here's another site that has instructions for the train loading and unloading modules. http://www.moc-pages.com/search_RESULTS.php?query=akiyuki&total=6&page=1&sort=best_match&filter=moc&personid= There are two unloading module instructions which mirror the unloading station. Two people have got different instructions for the actual train module. There are still no instructions for the reversing station and the track changers, but are easy to implement once you have studied the loading and unloading stations.
  10. We will definitely need a layout area similar to the train layout. Will definitely push the others to the balcony next year.
  11. What about Rohan's dumper truck at the Brickvention GBC? I also recall several truck based modules in some of the GBC displays in Europe. Particularly the concrete mixers and the garbage truck (the type that pick the bin from the front and flip over the top).
  12. It was slipping off because it was a half bush that didn't have enough friction to keep it in place. Adding a full bush fixed it and it didn't come off till the end.
