Here's my newest project - Enigma Minor. It's compact, has a lot of paths (5!) and looks cool. The name was suggested in my question "how shall I call my new K'nex ball machine" It looks like project Splat, but I modified it. My add - ons on Splat:

- 1 extra path: Freefall
- 2 kinds of path separators: the classic version and the Infinity-Switch
- 1 new element, that I've designed: the dual ball element. (on path 4 and 5)
- less pieces!

Good luck with building!

Step 1: Pieces

Here's the piece count!

- Green: 244
- White: 138
- Blue: 289
- Yellow: 64
- Red: 1
- Grey: 9

- Grey 1 – way: 71
- Grey 2 – way: 9
- Orange 2 – way: 25
- Red 3 – way: 144
- Green 4 – way: 29
- Purple 4 – way: 106
- Yellow 5 – way: 137
- Blue 7 – way: 51
- White 8 – way: 35

- Blue: 50
- Gray: 37

- Blue clip: 4
- Tan clip: 4
- Y – clip: 26
- Blue hinge: 4
- Black hinge: 4
- Red gear: 6
- Chain: 46
- Battery motor with short lead: 1
- Original K’nex balls: 2 or 3

Total: 1537 pieces.

Step 2: Base

Let's start building! In this step, you'll make the base and the bottom gear. Good luck again!

Step 3: Receivers

A receiver's a path that brings a ball back to the lift. In this step you'll make them. Look carefully to the amount of spacers and where Y - clips are placed!

Step 4: Spiral-Bottom

Here's where you'll start building the Spiral. In the middle of the Spiral's the freefall. You'll also make that part yet. Look again carefully to the amount of spacers.

Step 5: Path 4 and 5

Now you'll make 3 elements at once; the new element, the switchback and the maze. It's a lot of work, so start with it!

Step 6: Spinner

This is the Spinner, a well - known element. This could be painful for your fingers, so be careful. 

Step 7: Spiral-Top

Again a part of the spiral. These 2 elements (spiral and freefall) are the last elements you're going to make. Make sure to check the last picture. It includes a few changes to the rest of the pictures, if you don't change it it wan't work!

Step 8: Top - Left

Now you'll make the infinity-switch and a path separator. Good luck with 'em!

Step 9: Top - Right

This part includes 2 path separators. Look carefully to the connection points with the other parts!

Step 10: Motor-house

You're almost done! Just make the motor-house, and after that the chain.

Step 11: Chain Lift

Last part! Make 2 sets of 15 chains, and one of 16, with at the end a chain-claw.

Step 12: Finished!

You're done! If you're maze is stopping the balls, use gray connectors to stop the maze from going up. Thanks to tardis fan for this.

Have fun watching or changing it! Please give me pictures of your finished model, I'll add them to this step.

<p>are you still alive? please make more ball machines!! :)</p>
I'm about to install the chain right now... after spending several hours on this project, the only thing I can find bad to say is.... You must have the tiniest little girl hands..... it was tough to get into many of the places to make connections.... I has been a much fun build and I can't wait to see it in action.... I'll be sure to send you a pic... thank you for a nice project <br>
cool i mite build later or when i have time
Are all the cogs needed? I only have 3.
Are all the cogs needed? I only have 3.
how far are you into the enigma major?
I started designing. I've 3 new lifts in mind, I'll go build it within a few weeks.
when is it done?
hey RNB this ball machine is awesome!!!!!!!<br> this is going to be my first ball ive built so thks for that!<br>can i keep u updated on how im going because ive never made one before!<br>thks if i can<br>=D<br><br>
Sorry for the late reply! How far are you?
Ik ben trots op Nederland door jouw SUPERRRRRRRRR ballenbaan!!! <br> <br>Dankjewel!!!
Bedankt! Omdat deze baan zo'n succes is, heb ik besloten om door te gaan met de 'Enigma's'. Ik ben nu een gigantische baan aan het bouwen die Enigma Major heet, later komt er nog een Enigma Micro
Eigenlijk zou je ook instructies moeten moeten maken voor de Enigma Micro <br>(hoeveel stukjes gaat die in beslag nemen?) <br> <br>Alvast bedankt!!!
Enigma Micro: Nog geen enkel idee :-P. Eerst bouw ik de Major, later komt Micro nog.
waneer komt de major
Ooit hopelijk. Ben nog steeds niet gestart :(
maak dan een micro,dat lukt vast binnen 2 weken ;)
EPIC imma build it if i have enough blue rods <br>god i hope i have enough
I just finished the machine (pretty cool, by the way) and everything works but the Spinner. For some reason, the ball seems to fall out a fraction of a second too soon, landing on the track below. Then its momentum carries it in the direction it's supposed to go, however, the Spinner, which is still spinning at high speed, stops the ball and causes it to go backwards off the track. Is the Spinner supposed to carry the ball all the way down until it starts to go back up, or is the ball supposed to fall out but then roll through without the Spinner disturbing it?
The Spinner is supposed to disturb the rolling. Still, the spinner is spinning in the same direction as the ball goes, and it should work. If it keeps giving problems, add an extra fence at the back of the track.
I fixed it by replacing the red connectors and y-clips with gray connectors so that the track was slanted.
if this is an enigma minor, then what is an enigma MAJOR?
Thanks for the name! I'm gonna build an big ball machine soon, do you mind if I call it Enigma Major?
Can i see then plz on skype, when you started?
Just started, building a new lift as start... (tell ya on skype!)
awsome! :) :) :)
Nope, go ahead, i look forward to seeing that :P
looks relly good! <br> <br> <br>10/10 <br> <br> <br> <br>MUST MAKE IT.
Make it, and gimme pics of it, I'll add them to the last step!
well....... Later on but I will make it. <br>
is it the big chain not the small<br>
Big one.
i made it and modified it so you can use only one ball
what is the coaster in the background of the first pic?
That's the DoubleDare Racing Coaster<br>
is that a standart set?
got a video? <br>
Nope, I'm sorry. My cam sucks at taking vids. When I get a better cam I might rebuild it to film it though.
Excellent Ball Machine 10/10 - I'm defanitly building this
Thanks! Gimme pictures when done, I'll add them to the last step :-)
Nice job! I'm going to try to make this soon.
Cool! Gimme a picture when it's finished, I'll add it to the last step!
Here are some pictures.<br>This ball machine is great! I'm glad I spent the time making it. I made a few changes (such as the motor) but didn't change the design.<br>I also added grey connectors on the maze part, which used to stop the ball.
Thanks! I added your first 2 pictures to the last step, and some text about the gray connectors. Have fun watching it or changing it!
My one won't be as clean as this,<br><br>Because on part of the spiral i had to use a bendy rod with orange connectors because I think i did something wrong.
The spiral is a bit hard to get good. You'll have to push quite hard to get it in position.
Iv finished the step for the spinner and there's loads of problems,<br><br>The spiral doesn't work<br>When the ball is in the Maze it always stops<br>When the spinner drops the ball it doesn't roll along the track and if it does it gets stuck<br><br>The switch back path, works until when it gets on to the track back to the lift the spiral is a tad low so it blocks it.<br><br>Only the Freefall works!
