Introduction: Knex Leave Me Alone Box

Picture of Knex Leave Me Alone Box
Hello everyone! What I have here is a small project that I worked on for a few weeks: a leave me alone box! I've seen lots of these boxes around on the internet, so I decided to build one out of Knex. :-) It is purely mechanical and uses things like an arm, crank, and a more compact version of the motor switch system I invented in my skeeball machine

Note: If you use the mechanism anywhere else, please give me credit. 

Here's a video of the box in action:

Step 1: Time to Count! (Optional)

Picture of Time to Count! (Optional)

These are the pieces I used to build the leave me alone box. The box uses a lot of pieces, so if you don't have enough you could make it with blue/yellow rods instead of green/white rods. The pieces below are listed with their classic-colored names. Counting is so much fun!

Rods: 436

green- 263
white- 156
blue- 8
yellow- 7
red- 2


Connectors: 265

dark gray- 24
light gray- 9
red- 29
green- 7
yellow- 24
orange- 13
white- 51
blue- 14
purple- 94


Other: 57

blue spacer- 20
silver spacer- 11
tan clip- 11
black Y clip- 10
medium yellow gear- 1
small blue/brown gear- 1
newer-style battery-powered motor (green)*- 1
blue hinge- 1
black/green hinge- 1

Total: 758

*You must use this type of motor. Keep in mind that motors of different colors go different speeds.

Step 2: Bottom Panel

siamesederp (author)2017-04-17

any1 know where i can get micro knex for cheap?

Shadowman39 (author)siamesederp2017-04-18

There's lots of them on eBay, most likely good deals.

siamesederp (author)Shadowman392017-05-19

yeah, I got a Screamin Serpent, Loopin Lightning, and a Doubbledare Duelling Coaster all for $40 plus an extra 470 pieces because the Screamin Serpent shipped late =)

Shadowman39 (author)siamesederp2017-05-21

Haha that's cool, do you like micro coasters more than SS?

siamesederp (author)Shadowman392017-05-22

I like them both because they both are so fun. I can't decide which I like better

Shadowman39 (author)siamesederp2017-05-23

Hehe, it's good to like building a variety of things.

siamesederp made it! (author)2017-05-19

Here are the pictures, Sorry for the track in the background

Shadowman39 (author)siamesederp2017-05-21

Looks nice! I've added the picture to the last step.

siamesederp (author)2017-05-19

Nevermind, Fixed! =D It is sooooooooooooooooooooooooooo awesome though, ju st had to replace a few pieces =D

siamesederp (author)2017-05-19

Lever moves twice! Plz help! D=

dynamite_kid (author)2017-05-05

this looks really cool and i want to build it, but the only problem is that i dont have enough pieces

but its AWESOME!!!!!! i wish i had enough pieces to build this

Shadowman39 (author)dynamite_kid2017-05-06

Thanks! Is it the box itself that you don't have the pieces for?

dynamite_kid (author)Shadowman392017-05-09

yes

siamesederp (author)2017-04-02

Going to try to build it, not sure if I have 263 little black/green rods tho....

Shadowman39 (author)siamesederp2017-04-03

Most of the green rods are used in the box itself, so you could make most of the box out of different pieces if you wanted to, like this white rod lattice:

siamesederp (author)Shadowman392017-04-29

Ordered $40 worth of knex, half of it was for this, the other half for my new K'nex roller Coaster I am going to post the preview for in a minute or two ;)

Shadowman39 (author)siamesederp2017-04-30

Cool! I'll go look at the coaster.

siamesederp (author)Shadowman392017-05-04

oh yeah, I had even less whites than greens soooo.... I couldn't make the white lattice

Shadowman39 (author)siamesederp2017-05-06

:-(

DukDukboy101 (author)2017-04-02

Man, where do you get all this knex?!?

Shadowman39 (author)DukDukboy1012017-04-03

Mostly from eBay.

NobleD4 (author)2017-02-26

Ive built this but i cant switch the lever ): please help

NobleD4 (author)NobleD42017-02-26

Fixed it, works great

Shadowman39 (author)NobleD42017-02-26

Cool, thanks for building!

random_builder (author)2016-12-31

AWESOME!!! I think that this is the best knex anything on instructables. It is very cool and the instructions are very good. I had to tweak it a little but it still works great.

Thanks man! I'm glad yours works well.

Jedi_man (author)2016-07-04

This was a very fun build! Very good instructions.

I've always wanted to make one of these boxes :)

Shadowman39 (author)Jedi_man2016-10-09

Thanks!

Proassault (author)2016-10-08

Nice job! I made it but I needed to make 1 or 2 modifications to make it work

Shadowman39 (author)Proassault2016-10-09

Thanks, I'm glad you got it working!

The Knex Inventor (author)2016-06-04

Looks like a fun little project. I will have to build it sometime.

Thanks!

You're welcome! :-)

GuppehsWorld made it! (author)2016-03-06

This is such an interesting build. It took me about 1 hour 15 minutes to make. I love all the complex mechanisms in that small of a place. :D

Shadowman39 (author)GuppehsWorld2016-06-27

Thanks for building, nice job!

dlux3888 made it! (author)2015-10-06

Just finished the "Leave Me Alone Box" last night. Fantastic build, fantastic design, and fantastic instructions. I had a few snags but nothing that couldn't be fixed with a little bit of tweaking. Loved it! Thank you Shadowman39 for the design and instructions!

Shadowman39 (author)dlux38882016-06-27

Thanks for building, glad you were able to work things out!

random_builder (author)2016-06-01

this thing is awesome!!!!!!!!!!

Thanks!

NorthernF (author)2015-12-30

Hey shadowman I hope its ok but I used a bit of your mechanism in a K'nex ball counter I made I just used the casing for the motor switch system but I changed all the other parts of the auto turn off I hope thats ok I credited you in it :)

Shadowman39 (author)NorthernF2016-06-27

That's ok, I saw your ball counter, nice job! And thanks for the credit.

SacredSpriter (author)2015-11-05

I'm just wondering, how did you put this into the skeeball,have it release the balls (hahahaha
) and be activated by a quarter?

This was used many times in skeeball, there were 6 of the motor switch modules: 4 for the counter and 2 for the startup/shutdown.

Linkin_J_Knex (author)2015-10-17

Hehe great idea! I have to remember to build this!

Thanks!

crestind (author)2015-08-26

Had to watch the video to understand what was happening. Double crank to reverse the rotation. Brilliant!!!

Shadowman39 (author)crestind2015-08-27

Thanks! :-)

SirDaftBunny (author)2015-07-05

This was a really cool project to build! I had a few difficulties though. The part that is supposed to turn it off worked a lot better when I wrapped a rubber band around it, adding more grip and size. One more thing, please highlight the importance of connecting certain gears! I forgot to and ended up having to basically dismantling half of it :P
