Knex Ball Machine: Elysium




About: Hey! I'm Sandroknexmaster. I like building with knex, especially ball machines. I live in Belgium. I speak Dutch, but also English and French. I hope you like my stuff, and like always comment, rate &...

Hello everyone!

I am proud to present you my big ball machine Elysium. It is the biggest and most complex machine I have made so far. There are some unique features like a moving floor, 8 new lifts, and multiple new elements.

The lowest floor is not like any other white knex ball machine floor, as it is motorized. The floor makes random movements, so you never know where the balls will end. The surface itself is also different than white connector floors: this one is a combination of white a red connectors. This pattern was much more flexible, necessary to make it move.

If you want more than a moving floor, take this: All lifts in this machine are new. 9 lifts in total, 8 new lifts, because one lift has been used twice. Some of them are small and simple, others are bigger and more complex. The last lift also serves as a path separator.

Besides the new lifts, there are also multiple new elements. You can find one new path separator as well.

Because this machine's networks are not very clear and interconnected, the video is split up in so called 'parts'. There are 4 parts in total. This machine has 18 paths and 7 connections. Connections are smaller paths (that are not really long enough to be called paths) that connect one part to another. Here's an overview:

Part 1: 2 lifts, 4 paths

Part 2: 3 lifts, 3 paths, 2 connections

Part 3: 3 lifts, 5 paths, 3 connections

Part 4: 1 lift, 6 paths, 2 connections

    Awesome ball machine! I really liked the moving floor. Will you be posting instructions for all the lifts, or just some of them?

    I still have the rest of the lifts and I won't take them down before posting instructions, I just don't know when :p Thanks!

    Hallo Sandro,
    Ik ben jou balmachine Elysium aan het nabouwen. Ik heb al verschillende elementen gebouwd en ben nu bezig met het platform. Kun je mij vertellen hoe je het platform laat bewegen? Ik kan het op de video niet goed zien hoe het verbonden is met de motor.

    Op ware grootte of een kleinere versie? Ik ben benieuwd :)

    Eigenlijk zijn het gewoon verschillende stangen die de vloer naar omhoog duwen, naar benden gebeurt door de zwaartekracht. Ik heb de vloer nog altijd staan en hoop er ooit nog instructies voor te maken.

    Veel succes!

    how long does it take you to want to take apart your ball machine(How long until you decide to take it apart)? I really don't want to yet I have lots of k'nex ideas and are really inspired to do more k'nex Instructables! I'm already thinking of doing so however should I keep it up in case people want more information on it? Epic ball machij btw as usual!!

    Usually around 1-2 months then I take it down. Well that's why I told you to add as much information as you can from the beginning, then you can take it down whenever you want.

    Who am I to judge about that? :)

    Besides all this knex I have some lego sets as well and I've always liked to build them. But I have a lot more of experience with knex.

    I don't think one of them is better than the other, it's just what type of parts you like most to build with.

    Yes I know, it's taking a lot of time, I don't (can't) work as fast anymore as I used to. But normally I will post them all, though it could take months.
