I’ve published the Instructable for 1 of the 3 lifts I designed for my ball machine Ribdul: the Separating Chain Lift. I originally made the Instructable back in August 2021 so that I could take apart the enormous original Separating Chain Lift, freeing space in my living room for making other Instructables. Here is a video and a link to the Instructable.
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.
