Introduction: K'netic Energy - K'nex Ball Machine

Picture of K'netic Energy - K'nex Ball Machine
This is K'netic Energy, and largest and most complex K'nex Ball Machine to date!

To see a video of one ball going through each path, click here:

Here are some statistics about the machine:
- over 25 000 pieces
-5 lifts
-4 motors
-16 balls
-20 different paths
-6 months of construction

This machine also featured some new element designs as well. Some examples are the 2 way bridge over the door, the free-fall lift, the free-fall path with large yellow gears, and the trap doors.

An interesting fact about the machine; near the end of construction, carpenters came to redo my floor. As a result, I had to disassemble the entire machine in small chunks, and move it to my basement until the floor was done. Afterwards, I had to re-assemble and -realign all 28 sections that had been taken apart. The finished product looked exactly like before, luckily, and with no damage.

I highly doubt he has. I mean he has not posted any 'Ibles to indicate he has that many pieces and he only joined 4 days ago...

koolcoasterkid (author)hunter9992014-02-12

He may have that many pieces, as he has already recreated Shadowman's Skeeball Machine.

hunter999 (author)koolcoasterkid2014-02-15

Hehe! Yep he sure did

Yeah, he probably got the picture off Google or something

Great mechanism! As a bit of a Friday treat, I showed 5 elementary classes your video, and it was a big hit :D Thanks for putting your ingenuity out there for the countless ways it can open eyes and inspire people! Adam

I'm glad they liked it! :) Thanks

friken awesome!

codongolev (author)2013-09-24

When people say that you have too much time on your hands, just say you were practicing spatial reasoning and creative design. Then ask about their video game/tv habits.

Haha, thanks.

knexpert#10829476 (author)2013-09-24

WHOA!! That thing is awesome!!!

KneXtreme (author)2013-09-21

Nice job!

CrayfishYAY (author)2013-09-18

So were you the only 1 who did all of this? Or did you have someone else help you?

No, it was just me. Some friends do help sometimes but they just do small parts.

Lindie (author)2013-09-19

Wow! This is soooo cool! And your filming of it was great! How long did this take?

koolcoasterkid (author)Lindie2013-09-19

Thanks. It took 6 months to build.

ThePuzzler (author)2013-09-19

Whoa dude... That is awesome.

El Mano (author)2013-09-19

That easily has to be one of the coolest things I've ever seen.

Tazo (author)2013-09-18

One of the coolest things i have seen!!!

blomeclown (author)2013-09-18

Why do some people have this childish fascination with rubber balls rolling across plastic ramps, down plastic spirals, up plastic elevators leading to moving ramps...............
Hang on ... video just ended ... have to restart it ... must watch it again ... and again ... and again ...
That is so neat-----

Awesome! How old are you?

I'm 16 turning 17 in not long.

mwacuff (author)2013-09-18

Nice! Like others commenting here, I'd like to know more about the construction. We would like you to expand upon this Instructable.

Speaking for myself, I'd like to know the construction details of each lift; how it's powered, the supporting framework, and detailed photos. How do you design the various helices and loops?

I think it's obvious that you didn't buy all the K'nex pieces in a single kit. So which K'nex kits did you buy to make up this project?

I think everyone here would love to know more! Thanks!

koolcoasterkid (author)mwacuff2013-09-18

Look at my post about construction.

koolcoasterkid (author)2013-09-18

Since a lot of people are asking about the construction: I do have construction pictures and videos taken at certain points of the construction of the machine. However, these pictures and videos are not the best quality as I used my iPad to take most of the pictures (before I got the new camera). If you guys don't mind this, I have no problem posting a detailed construction Instructable.

fx8 (author)2013-09-18

is awesome and big :D great idea your fantasy.... wow i can't say anything else

Saad 2715 (author)2013-09-18

The coolest homemade structure, I have ever seen in my life

evilmadcow (author)2013-09-18

lumi3005 (author)2013-09-17

I already commented it in Youtube but again...respect about that awesome machine. 25k pieces, did you get a special discount from Knex???

koolcoasterkid (author)lumi30052013-09-18

No, but I wish I got a discount. :p
