This ball machine is tall and has 4 paths so I was wondering if anybody had ideas on where to make a fifth path. I have a lot more knex pieces. So I can build a lot of things. And yes I attached a working ferris wheel to my ball machine with gears and chains.

The ball valve of my air cannon releases the pressure once it climbs above 5 psi. Is there any way to fix this? Or am I stuck with a $30 door stop I'd buy a new one but it just started to leak air, it was working, plus it's glued to my U joint, and really don't wanna rebuild it.

I was wondering if anyone on these forums think they could make one of these. It is such a interesting time piece and i think it would look great in any modern living room. I want to make one but the kits are kind of exxpnesive and its more fun if you can make it on your own. Here is some pictures. Enjoy and thanks for your input :). Toby Mac

Hi everyone. I have ordered my 3D printer and in the mean time, I am building my files I will be printing. 1 of them is rounded and has no flat surface. How do I go about printing this? Do I need to create a base to print it on or will the product I use to make the bas sticky be enough? Any help to this beginer would be appreciated. K

Hello, I want to make some glowing juggling balls (using LED probably), but I have no idea about what ball to use, how to make it turn on and off and how to balance it. I tryed the led ping pong balls (link at the end), but they're too small and light. Any ideas? How do the glowing balls work (those that from Yo-ho, for example)? Thanks.

Hi there! I noticed how hard it is to find elements for your k'nex ball machine. So I decided to make a guide so you don't have to waste time searching for elements! So, if you have made a ball machine with new elements, please tell me and either post a link or attach photos so I can add them to a future instructable! K'nexers who have given me permission to do this with their elements: Sandroknexmaster

This idea just popped into my mind and I thought it wouldn't be that complicated to make, maybe even in time for christmas! I was thinking about juggling balls that would light up upon movement, except I don't know how to make them. I don't know how big/heavy motion sensors are, but couple them with leds and a battery, stick everything inside a plastic ball and presto.. or am I simplifying too much?.. Better than that would be to use the power generated by the movement to light up the leds, somewhat similar to Powerballs, but that I have no clue as how to do.. So, any ideas on how to make them?

Hello everyone! I was hoping someone here with better understanding of engineering or just a fresh take on the problem can help me out. Im working on this art project where I have a metal ball, aproximatelly the size of a basket ball, and i wanted to make it rotate continuously on a stand, in a way that all sides of the ball were shown eventually. I've thought about this 3 axis sytem where each axis would rotate in turns to keep the ball rolling in diferent directions. Basically its like the insides of an analog mouse where the ball would rotate the gears and give the input of the location of the pointer, except here the gears should rotate the ball. I've been trying to build something close to that with some K'NEX and a simple rotation engine that came with it but im not getting nowhere. I thought of building the gears myself but im finding it hard to come up with a plan. What would the gears be shaped like? What size? what distance between them? Even with trial and error would take me forever @.@ Anyways, any input, ideas, comments apreciated, Thx!

I began collecting a few bowling balls with the intention of making decorative art in my flower beds. I have a neighbor across the street who undoubtedly has so much disregard for me that he reported me to the city code enforcer who said bowling balls were against code. I had a supervisor come and look at my yard and the bowling balls and he said it is art. The other code enforcer has required that I "anchor" them down. Does anyone have any suggestions? I'm sure no matter what I do the neighbor will not like it. He hates my trees. I have humongous oaks and lots of plants and shrubs. He has complained for 16 years now. He sits on his front porch and watches everything I do. He reported I had rats. They found the rats nest on his property. He claims the termites come from my home. Believe me, I have a small brick ranch that I do all the upkeep on. I think he just can't stand it that he can't tell me what to do like he does the rest of the neighbors. I'm a woman-maybe that's his problem. Anyway, how do I "anchor" my bowling balls without taking away from the art of them in my flowerbeds? Please help me. I want to abide by the city codes.
