Akiyuki Brick Channel | LEGO GBC module : Ball Factory ver.2 @akiyuky | Uploaded 12 years ago | Updated 54 seconds ago
I added some improvements to the ball factory module, because the former module didn't support 1.0 balls/s.This new module can carry at 1.3 balls/s.
All mechanical moves in the new module are driven by only one PF XL motor and synchronized.
I was inspired by superbird28's videos.
