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:


If you want to build the leave me alone box, then move on to the next step!

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-Co4 months ago
Try making the lid heavier by adding a weight to it. And thanks!

Shadowman39 (author)  lolboy8769 months 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)  lolboy8769 months 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

Nice!
I tried to make it again and I works
Shadowman39 (author)  jackson98821 year ago
Yay!
I built it, looks good but something is wrong with the motor part to make the switch turn off
Shadowman39 (author)  jackson98821 year 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.

Nevermind about that. I sorted it out. Im having a new problem. Ive finished the machine.
However, when i flick the lever, It turns on, but the mechanism inside the box doesnt turn off.I have to manually pull back the off mechanism to make it stop. Please help me shadowman :)
Shadowman39 (author)  The Cannoneer1 year ago
Does it take a few cycles for it to turn off, or does it not turn off at all? You could try adding more weight to the lid or a rubber band on the arm to make it push the off switch easier.
It does not turn off at all.
I have to break open the box and pull back the arm to get it to stop.
I was thinking that maybe the motor wasnt strong enough but, who knows? :)
