Maybe I should present myself here. Not much to tell though, because I've only built one module so far. Didn't even invent the mechanism, just copied it from a non-lego marble machine. [1]

Nice! I'd seen that mechanism, too, and wanted to build it. Now I don't have too. It has a lovely organic motion. Don't apologize about the copying bit; take credit for a fabulous implementation!

That's amazing. Just watching the video is mesmerizing. Haha

Love it! The motion looks really smooth and almost natural like Slow said. Great work!

I had some more time to look at this tonight and it's just amazing. It's hard to believe this is your first GBC module. I love the Dr. Seuss-esque character of the build. I love the fine mechanical details, such as where I would have been content with sliding motion (under the stair lift), you used wheels. And it processes at precisely one ball per second. Bravo!

Torso, what's your background?

Glad you like it! I like how it moves too. There is of course nothing wrong with copying, but I don't want to take credit for something I didn't invent. It's not perfect, but I'm still happy with the implementation.

I work as a computer programmer. Don't have any mechanical background even if such things have always fascinated me. Started building MOCs fairly recently, so this is my third Technic MOC. Don't know if adding wheels was overengineered, but it does run smooth. With experience it's easier to know when one can be lazy.

And one ball per second is in the specification. As a programmer that's very hard to ignore. Though I did start by deciding how fast it should move and then made the claw hold enough balls for that.
