Lego Marble Pump

The pump mechanism is copied directly from the cad drawings provided at www.foxbox.nl. The rest is my own. It uses 3 flip-flops to take 4 routes down. The music is Chemical Brothers.

I had the same problem- it kept jamming until I used two 40 tooth gears & two motors. I also put a 45 degree angle into the bottom of the tube the marbles travel up. This seems to reduce stress as there is less weight from marbles pressing down on the mechanism.
