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:
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:
