My Great Ball Contraptions (GBC) Modules

Recommended Posts

Made another module. I think this GBC thing can be addictive.

Looks like you need a few more balls, I always find GBC interesting to watch

Yup, more balls would be good. The ones I have now are from Tom @Brickworld 2013 on the promise I build a GBC with them.

Very nice! I find these fascinating as well.

Is that a yellow frog in the second module?

That ball pump is incredible. It's also got a very simple mechanism, which it really doesn't appear to have!

I've seen such a design years ago. It is nice and surprisingly simple despite looking very advanced. The problem however is that in order for it to work there has to be a full stack of balls as tall as you want the pump to pump. This locks up lots of balls at the time. Nice to see one that feeds itself though.
