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:

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

Amazing! I added another one of those grey 1-slots + y-clip to make sure the the other one doesn't fall off, and I had to add double-sided tapeto the turning-off part.

1 more ish Shadowman , the lever does not turn the motor off now :-( WHYY ME

You may have to continue adjusting the part that used to get jammed. You could also try adding a weight to the lid, that has worked for some people that were having problems.

Thx for the tip :-) it works fine now
1 prob the lever always gets jammed when I try to turn it on and I keep having to open it up when the switch breaks off .... Any suggestions btw great build :-)

You'll have to tinker with the part that switches the box off, since that seems to be blocking the lever from pushing. The dark grey connectors (or purple connectors in your case) on the top should slide over the bottom connectors when you turn it on. And thanks!

It dose not slide up properly

Hi Shadowman, my box doesn't always turn itself off. Do you have any tips?
BTW this thing is so cool, I've told my friends about it. :)
Shadowman39 (author)  Fr-Pa-Co1 year ago
Try making the lid heavier by adding a weight to it. And thanks!

I have just found my knew again and saw this link when searching for a useless box for a Christmas present. and thought why buy one when I can build one
Shadowman39 (author)  jdeighton1 year ago
Awesome, have fun building it!
This is really clever! I like it :D
Shadowman39 (author)  epicpenguin131 year ago
Thanks!
This looks neat. ima build this soon :D
Shadowman39 (author)  megustatrains2 years ago
Thanks, and have fun building it!
D: just saw that it uses a yellow gear. i don't have any gear of that size D:
Shadowman39 (author)  megustatrains2 years ago
You can use a red gear instead. To do this you'll have to move the blue gear back one blue spacer (towards the motor), and you'll also have to move the red gear one blue spacer towards the blue gear.
I actually dont have any gear of that size. i might find a red, but i dont know. ty though :D

I tried to make it again and I works
Shadowman39 (author)  jackson98822 years ago
Yay!
jackson98822 years ago
I built it, looks good but something is wrong with the motor part to make the switch turn off
Shadowman39 (author)  jackson98822 years ago
Other people have had that problem, it would be a good idea to look at step 8 and make sure everything is built correctly. If it is built right, you could add a rubber band to make the arm want to go downwards or a counterweight to the lid.
