Well, here is a small ball machine, with a twist - No lift!

What?! No lift? How the heck does that work?

Well, it works like this. The track is a smooth flat circle, sitting on the base. The base has four "Arms" that stick out, and at the end of each one is a mechanism that makes a rod go up and down. These up-down rods connect to the circular track and cause it to oscillate so that the ball rolls around in a circle. Watch the video to make sense of it all.

Make the track. It has 48 Yellow connectors on the inside and 48 on the outside. The inner track is solid, but the outside is not connected. It's made of yellows + Green rods. See the following two photos to see what I mean.

1: Make this

2: Add blue rods

3: Make 12 of these

4: Attach them like so

5: Close up

6: Make four of these

7: Connect them

8: Make this

9: Make four of these.

10: Make four of these too

11: Put the first four on like so

12: And the other four on like so

13: Second view

14: Put the track in like so. It's connected to the frame every 6th piece.

15: Close up of what the connections look like.

1: Make these two bits

2: Put it together

3: Make these parts

4: Make this. Be sure you get all the spacers in the right spots

5: Close up of one end

6: Close up of the middle

7: Close up of the other end

8: Build this

9: Make this too

10: Put them together

11: Add that axle thing.

12: Close up of the end

13: Put that one bit on top

14: Add the yellow rod/hinge connection

15: Close up

16: Add on the rest of the frame, like so

17: Make four! Leave out one yellow rod on top of one of them. (you will have to take out one yellow rod later)

1: Make these three bits and get the spacers ready

2: Put the geared rod through the motor hole, and the other two as seen. Put spacers on.

3: The Other side

4: Make this guy

5: Another side

6: And another view

7: Make four!

8: Build this

9: Make This gear assembly from this and the next three photos

10: ---

11: ---

12: ---

13: Make this

14: Build these four corners

15: Build these three

16: Build this

1: Put one of the corner pieces on it

2: Add one of the other pieces and put on another corner

3: Same again

4: And once more

5: Add that center bit

6: Add in a gear bit into all four openings

7: What it should look like now

8: Add the yellow gears with the teeth facing down

9: Close up

10: Put that piece on top now.

10: Add motor on like so.

11: Close up

12: connect the structure you built in the last step

13: now connect the rest of the other structures

1: Turn on your motor until one of the shafts is like so

2: Take your next shaft. Lightly lift the yellow gears so that you can turn one shaft while the others stay stationary. Make it so that it is 90 degrees farther in rotation than the previous shaft.

3: It will look like this then

4: The next one will be like this, and the last one will be pointing down. You may want to double-check that they are all aligned.

5: same as the last step keep going until each one has been rotated 90 degrees

That was confusing, hopefully, you did it right, though. You all done now!

You are now able to look away hours of your life staring at a ball rolling in a circle.
