Introduction: Quadrivium - KNEX Ball Machine

Picture of Quadrivium - KNEX Ball Machine
This is my 10th ball machine "Quadrivium". This is my most complex and best ball machine to date. This ball machine features a chain lift with 2 types of claws in a pattern, 8 paths, 4 new elements, and it only took me less than two weeks to build. My younger brother helped me with a few things on here, balls barely fall off, and works great.


Step 1: The Bottom & Network

This is where the balls come to be lifted by the chain lift and up to the top.

Step 2: The Switching Yards

This is how the balls connect to the four support towers.

Step 3: Path 1

This path features MinnesotaRandomCrap'slowering beam from Phobia and a path my brother helped me with.

Step 4: Path 2

This path features sandroknexmaster's spiral stairs and my new kind of tipping path.

Step 5: Path 3

This path greatly features me and my brothers' simple alternators that we constructed on our own.

Step 6: Path 4

This path features my new mini chain lift bridge with rails.

Step 7: Large Ball Alternator (paths 5 & 6)

Paths 5 and 6 are powered by my new large ball alternator.

Step 8: Paths 7 & 8

These paths combine to act like a mini racetrack where two balls are released at the same time by a two-ball dropper I made for the balls to fall down the chute first.

Nice ball machine. I like path 1 with that ball arm thing. BTW it seems like a lot of people use deadmau5 music.

And actually, the ball arm thing in path 1 wasn't made by me, it was made by MinnesotaRandomCrap

Aww yeaah. Someone finally used my own new element! :3

Anyways, great ball machine, you have definitely improved.

As to all your comments on Exodus, it had to be destroyed, because we got our basement finished. But there is a new one coming with no previews or release date, but it is 50% done or so.

Yes, and thanks. I think it is believed that 95martb (martijnb95) is getting everybody into deadmau5 these days. :l
