I designed a simple marble filtering tile. The gear connected to the motor spins and the marbles fall through the holes made on the gear. Assuming the tile is connected to other compatible tiles, the marbles can fall either on the tile or the surrounding tiles connected to it. I was able to unintentionally (?) make the gear spin in one direction continuously. The gear slides against the servo axis allowing it to spin clockwise continuously Some parts I would like to improve on for my tile is making smaller but more holes to make the filtering more interesting as well making the filtering contraption smaller and centered so the balls can get delayed more.
