knock detecting box

unlocks when knock in the correct way

So basically it's just a box that unlocks when you knock the secret knock, the locks when you get it wrong

If anyone else wants to make one here’s the instractable i get most of the code from http://www.instructables.com/id/Secret-Knock-Detecting-Door-Lock/


For power I’m using a phone charger from a nokia that passed away.


Probably should have use a smoother rod, but this one works fine, it has not jammed so far.



my crappy soldering );




In case you did not know the box is a replica I made based of the game minecraft .
