  1. This lego great ball contraption miniloop uses a Cardan mechanism to lift the marbles up, after that they role down the strings and back to the start again. It is very reliable and can be powered by a motor or a hand crank. If you want the free video instructions they are here.
  2. This lego great ball contraption module is designed to look like a lego molding machine. Their are flashing lights on the top and a screw mechanism to get the marbles back up to the proper height. The flashing lights on the top are powered by this switch (They are a bit hard to see in the video)
  3. Hello, this I'm my GBC zig zag module inspired by Akiyuki. This is my first time using eurobricks and I am not quite sure how to use it properly, is this the correct way to post? Any help would be great :-) The module is here.
  4. Hi there, Click here to download the building instructions on my website! It has been a while since my last GBC. But I have made a new one with new modules in it;) Click here to watch the video on my website with more information etc.: Here's some information about the LEGO GBC 8. To download the building instructions and watch the pictures, please visit my website: http://pv-productions.com/lego-gbc-8/ This time I used over 2000 LEGO pieces. I used 2 XL motors. One for all the modules and one for the airpump. I also used the LEGO NXT to control the LEGO GBC with your smartphone, so you can wireless turn it off and on again. You can also control the GBC with a mechanical switch. I also used the LEGO NXT for measuring data for more details. So now you can see the balls that have passed by, the average amount of balls per second and a clock to see how long the GBC is running. The mechanisms and functions, which I used, do not all have names. So I named them again by function. 1. Stop-go mechanism 1: Stops balls and let them go by at the right time. 2. Sinusoid: Moves the balls by making a sinusoid motion. 3. Stop-go mechanism 2: Stops balls and let them go by at the right time. 4. Elevator: Lifts the balls to a higher level. Every time 3 balls can fit in the cabin. 5. Bridge: Leads the balls of yellow tower to the blue tower. When the elevator(4.) is down the bridge will go up and when the elevator is up the bridge is down. 6. Stop-go mechanism 3: Stops balls and let them go by at the right time. 7. Vertical pushers: Pushes the balls in a vertical way up. 8. Color sensor: takes measurements of the balls. 9. Ball pump: Pumps every time one ball. A new ball takes a place beneath another ball and then pushes them up. 10. Android app: Controls the LEGO GBC Website: http://pv-productions.com/ Facebook: https://www.facebook...206638589482664 Youtube: http://www.youtube.c...op?feature=mhee Support site: http://lego.cuusoo.c...deas/view/51642
  5. Hi everybody, here is my new GBC module, using a particular "In basket" following and improving an idea of Platystick (a Techlug member) : the balls fall out of the basket by its side, no possibility of locking. The six-arms wheel system is already known for a long time. The chassis is optimized, the mechanics very simple : M-motor, 16t-20t, and on the one hand, worm gear-8t for the in-basket, on the other hand worm gear-24t for the 6-arms wheel. The module can be used in a classic GBC circuit just moving a flex axle (the same as the four on the 8285 front racks), then the balls are redirected to the end of the module using the ramp which isn't usend in the video :)
