I built a K’nex ball machine that I call Concatenation. It has 3 networks and 10 paths. It doesn’t work as well as my other ball machines, but I think it is cool anyway! When building Concatenation, I tried something I had never done before: combining two building systems, K’nex and Tetrix Prime. Tetrix Prime is a building system designed for building robots, but I used it to build parts of Concatenation. Below are some pictures and the video of Concatenation. See if you can spot the 5 places I used Tetrix Prime on Concatenation!

I made an Instructable for my very first K’nex ball machine path separator! I created this path separator accidentally while taking apart my ball machine Rolling Illusions. Below is the video and a link to the Instructable:
Flipper Separator Instructable
I made a new Instructable for an element I call Two Ball Flipper. I call this element Two Ball Flipper because when the second ball goes in, the balls flip over each other. Below is the video and the link to the Instructable.

My latest Instructable is for a simple K’nex ball machine element called the In and Out Spiral. I call this element the In and Out Spiral because the ball enters close to the back bone, and as it goes down, it moves out away from the backbone but then moves in toward the backbone as it exits. Below are the link to the Instructable (be sure to click on it) and some pictures:

Many ball machine builders (including me!) use the same basic idea of an element I call a Seesaw. For this element, a ball rolls back and forth on the curved track until it stops. Then the dumper releases the ball. I made an Instructable for my version of this Seesaw element. Below are the link to my Instructable, the video and some pictures.
Seesaw- A K’nex Ball Machine Element
I made another ball machine element and an Instructable for it. I call the ball machine element Trick Flip-Flops. It looks like an element containing normal flip-flops. However, I call it Trick Flip-Flops because the flip-flops are weighted on one side and go back into place once triggered by a ball.
Sorry there is no video. I just couldn’t get the element to stand up on its own for a video. It will be in my next ball machine, though. You can see it in action then.
Below is the picture and link to the Instructable.

I published my first Instructable for a K’nex ball machine element. For my first Instructable, I decided to do a simple element. I call the element The Catch Basket Zigzag. Here is a link to the Instructable:
