I have finished building my latest K’nex ball machine, Ribdul. Its name is pronounced “RIB-duhl”. It has 2 networks and 14 paths (and a unique white connector floor).
Ribdul’s name is part of a word in the language spoken by a fictional culture in the book series I am writing. (This is the same culture whose coins I named my ball machine Rujebime after.) The word means “a random number from x to y inclusive”, where x and y are numbers inserted directly into the word. Because the full word, “od-ribdul-x-id-y-od” is quite a mouthful, I used only part of it as Ribdul’s name.
I named my ball machine Ribdul because it embodies randomness. Balls pop in and out of holes in Ribdul’s white connector floor seemingly randomly. The path separators at the top of both of Ribdul’s networks distribute balls randomly onto paths. And Ribdul contains 4 mazes, elements where a ball takes a random route through an array of obstacles.
I built a K’nex ball machine that I call Rujebime. Its name is pronounced “ROO-jeh-bime”. It has 1 network and 9 paths. Rujebime is named after a type of gold coin used by a fictional culture that I will feature in a fantasy book series that I will be writing in the future. I chose to name Rujebime after that type of gold coin because I like the sound of the coin’s name. I designed 1 of Rujebime’s lifts and 11 of its elements. I used 1 of those elements on my previous ball machine Grid Tower II. Below are some pictures and a video of Rujebime. See if you can spot the plush sloth and the 2 plush binturongs in the video! (Note: While filming Rujebime, I frequently moved the binturongs.)
There are 10 kinds of people in the world: Those who understand binary, and those who do not.
10 is the number 2 in binary.
I made an Instructable for the path separator I designed for my ball machine Grid Tower II. The binary counter is my most complicated path separator. It separates balls while at the same time counting in binary. Below are the video and link to the Instructable.
I made an Instructable for the second lift on my ball machine Grid Tower II. The lift originally had 8 arms, but I removed 4 of them to make it work better. Below are the video and a link to the Instructable.
I built a K’nex ball machine that I call Grid Tower II. It has 1 network and 8 paths. The reason why it is called Grid Tower II is because it was originally based on my previous ball machine Grid Tower, but as I was building it, I decided to make it a castle-themed version of Grid Tower. I designed 2 of Grid Tower’s lifts, 1 of its path separators, and 15 of its elements! Below are some pictures and a video of Grid Tower II. See if you can spot the sloth and the binturong in the video! (Note: in the video, every time a new path starts, I move the binturong.)
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:
My latest K’nex ball machine is called Rolling Illusions. I called it Rolling Illusions because it is optical illusion themed. It has 8 paths and 1 network. It has a total of 15 elements and 5 lifts. See if you can spot all five optical illusions attached to the ball machine!
Below are some pictures and the video of Rolling Illusions:
Sorry, I forgot to put the name of the music in the credits at the end of the video. The name of the music is:
“Spring Mvt. 1 Allegro” and “Spring Mvt. 3 Allegro” by Antonio Vivaldi
My latest ball machine- Balls That Play The Piano- did not work out. The reason why it failed is because I tried to build it on furniture (a piano). I find that K’nex and furniture are not compatible because it is hard to build K’nex structures that can accommodate the inconsistencies of furniture sizes and shapes. Here are the reasons why some of my earlier failed ball machines failed:
-Ball Machine in the Dining Room- I tried to build on countertops which like furniture are hard to build on because of inconsistencies.
-Crazy Moment- I tried to build it on a rug which in that case was an uneven surface.
-Trampoline Factory- I tried to build it on a rug which in that case was an uneven surface.
