Hi everyone!

Here are the 13 new elements from my knex ball machine Paradox.
I tried to make the instructions as easy as possible to follow, and I hope I succeeded.
If you need more help or tips for your own ball machine, you can always comment or PM me.
Thanks for watching this guide and good luck with building!

Step 1: Simple Green Path

A simple element for warming up ;D

Step 2: Multi-clickers

Small wheels and vertical clickers in one. You can make it as high as you want.

Step 3: Easy Flipper

An easy flipper design,  like the title says.

Step 4: Wheel Path

This is a nice element to use some of your small wheels.

Step 5: Leapfrog

A pretty big element. The first ball enters and waits for the second ball, then they both fall down.

Step 6: Confusing Ferris Wheel

Instead of a regular ferris wheel, this is a cool extra you can add. The orange spokes can be changed in every pattern you want, this is just a basic pattern to show the effect of the gears.

Step 7: Catch 'n Spin

An easy but handy element.

Step 8: Geared Double Ball Drop

A cool looking element, perfect to add in your ball machine. For this version the big green gear is needed, but if you dont have one you can modify it.

Step 9: Flat Cross-Tie Spiral

This element works best with rollercoaster track, but you can also use orange tubes.

Step 10: Bended Trampoline

A restyled rubber band trampoline with good looks.

Step 11: Simple Flipper

Step 12: Spiral Clickers

You can make the spiral as long as you want. This one is for a standard red rod.

Step 13: Double Arm Drop

This element is originally invented by knexpert#10829476 and was first used in his ball machine ionization at 1:40 in the vid.
Here is my own version of that element.

I also made a instructables account today. But I can't make a instructable, because

he constantly says I have to verify my emailadress, do you know what I have to do?

Verify your email adress :p If it doesn't work, I don't know. You can always ask for help in the forum.

in step 8 it's spelled "modify" (constructive criticism) :P

sandroknexmaster (author)  www13910 months ago

Changed it, thanks :p

ok! I'll delete the comment above (it's embarrassing right?)

sandroknexmaster (author)  www13910 months ago

Haha no problem, everyone makes mistakes, and English isn't my native language :p

Whats your real language?

Dutch :)

Sweet. Just wondering, did you make the confusing Ferris wheel before clockwork?
And about the ferris wheel, I already saw it before I built it, but I never saw the mechanic (Serious). So it's not a reinvented concept, but I figured out the gears myself.
Let's say that I semi-invented it ;)
Ah, ok. Well nice job on the elements. I like the one with all the small wheels as it uses some pieces that are rarely used in machines. I might use it for my machine.
Yes, I always have more than half my wheels left, so I tried to invent an element that uses many wheels, and it turned out great :p

Haha, thanks ;D
Great job, my friend. Ingenuity shines through in these elements! :-)
Haha thanks :D
Dude, that is so freaking cool!
Thanks! :p
Oh my gosh, you used my element! This makes me feel so good inside:D
Haha no problem :p It looked good so I rebuild it from the vid, and offcourse I gave you credit for the whole concept.

Nice elements! In step 4 picture 14 good job on making the wheels stay in place. :-P
sandroknexmaster (author)  Shadowman391 year ago
Haha yes, but it was easier then I expected to keep them in place :D
Those are great bro. I kinda wish I was into ball machines.
It's never too late to start building ball machines ;)
Maybe not, but I would have NO idea as to where to start.
Same for me with guns ;)
Hmmmm... I would really like to see a gun from you. I bet you would be really awesome. BTW, I was wondering if you would make a guide that shows all the K'NEX guns that YOU have built, I would be really interested to see it.
I can always try! But first I have to finish instructions for new the lifts and path separators, I'm still busy with that. (and I'm going with vacation for 2 weeks, without knex)
BTW have you seen the question about Paradox in the description?
Oh, O.k, you do that, and I hope to see that guide from you soon. What question about paradox?
I'll probably start with building 1 gun, not a complete guide.
I mean the question in the description of this 'ible.
Wow, that leapfrog path is amazing! I defiantly really liked that.
