Introduction: Knex Ball Machine: Elysium

Picture of Knex Ball Machine: Elysium

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

Some more information:

Are you posting instructions for the shifting floor? Nice ball machine!

Not sure yet. Thanks!

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.

sandroknexmaster (author)JonaK12015-12-30

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!

sandroknexmaster (author)2015-12-14

That is also true.

sandroknexmaster (author)2015-12-14

Yes it is :p

I_Dont_Have_A_Name (author)2015-11-10

Damn... I wish i could have that much spare time... I mean Knex! yeah... :(

I respect your building skills


Yeah you'll need both if you want to make something like this :p

Linkin_J_Knex (author)2015-09-04

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.

oh OK :-)

is knex better than lego?


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.

OfficialKNEXGUY (author)2015-08-17

Hey Sandro! How are those lift instructions coming along?

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.

lgarg (author)2015-08-01

So what are the parts technically called if I go to buy them in the market

sandroknexmaster (author)lgarg2015-08-15

K'nex. You can buy new sets, but if you're looking for a lot of parts there are also a lot of deals on ebay.

lgarg (author)2015-08-01

So technically what are the elements called if I go to the market to buy them (author)2015-07-19

Incredible! I love it! Admire your work a lot! Look forward to have your full instruction! :)


Full instructions? That's quite a challenge :P There will be instructions for some parts of the machine.

Great job!


seempie (author)2015-06-29

Great inspiration source I'm planning to building own ball machine this summer i hope i succeed

sandroknexmaster (author)seempie2015-06-29


Nice, good luck with building!

ManMister (author)2015-06-16

Awesome ball machine :D!! Do you know specifically what lifts and elements your going to post for instructions?

Thanks! I hope to post them all, I don't know how much time it will take though.

Cool! Looking forward to it :)

MisterBukweet (author)2015-06-13

If this machine could order a pizza... I'd say that this is perfection personified. I am in awe... Awesome work... Now I'm selling all my K'nex, as I cannot achieve what you have done here...

Pizza ordering machine, you're inspiring me. Ha why would you sell your knex, try making a ball machine yourself!

lol... don't worry about me selling my K'nex. I'm just humbled in such talent sometimes. I do build my own machines. and in fact I'm in the design process of a totally new machine that I intend to call Flushed. I start building tonight. Anywho.. I love your work...

Nice can't wait to see it!

hardpunkkore (author)2015-06-14

You got ripped off at second prize. The most innovative ball machine since Metropolis, with 8 new lifts, moving floor, tons of new elements, you should have taken home the grand prize.

Keep working, you and Thibualt Art have gone places eith ball machines no one thought possible a few years ago. Looking forward to your nect creation.


Second prize indeed, but hey look at all those pieces I have, many other people can use the grand prize better!

Lolman4000 (author)2015-06-09

I only just watched the vid, And i'm thinking Wow...

Your first ball machine was bigger than my 10th would have been, and almost every one of your ball machines since then had amazing new elements, new ideas, and awesome layout.

I have to say that in my oppinion, you are a genuis on ball machines.

Thanks for the compliment!

Mysterious_Gal (author)2015-06-05

Hey you made it in time. Yay :)

Yes I did! :)

koolcoasterkid (author)2015-06-02

Very cool machine, nice to see it finally done! Tons of ingenious new elements and lifts, big congrats on it. I especially love the pendulum arm thing.

Thanks man!

Wow. True greatness. I think I can safely say that you are now the premier K'nex ball machine builder! You might even win the contest two years running... ;-) Fantastic job on those lifts, by the way!

Thank you! Do you still make stuff?

Yes, though not as much as I would like. I'm hoping to build at least one more ball machine before heading off to college this fall (after which who knows). So, hopefully something to look forward to later this summer! :-)

Good, looking forward to it :)
