This is my Lego automatic marble contraption that has power functions in it. It barely works because the conveyor belt goes WAY too fast for the marble, but don't worry, I will make a video when and if I get a Power Functions receiver. ;)

  • to make it go slower without the reciver is have a very smalll gear connected to a mediem gear conected to a large gear and the small one attached to the moter the small gear takes longer to make a full rotation of the mediem gear therfor making it go slower and that causes the lardge gear connected to the conveyer belt to spin slower than it without the gears

    i hope that helps

  • Thanks. :)

  • Sweet. Giving me a lego urge even though I don't own legos. :P

  • Nice video, but you can fix it by putting a small gear wheel from the motor to larger one going to the conveyer belt, just to gear it down. :)
