Learn How to Build This Complex Electronic Puzzle Box Using a 3D Printer and Arduino
Believe it or not, but as an adult I actually enjoy shopping for Christmas presents far more than I enjoy receiving them. Not that I don’t enjoy getting presents; I will happily provide you with an address to send me free things, but in my family we always put a lot more focus on finding the right gift for the people in our lives. Of course my family also places a lot of focus on humor and sarcasm, and when you mix both of those traits with gift giving, creatively wrapping presents becomes a competitive eve.
But as much fun as my family has wrapping our Christmas presents, Instructables user Scott Fisher, who goes by esseff3d, is in a class all his own. It seems he has found himself in an unofficial contest with his family to wrap presents in more and more elaborate and difficult to open ways, and that is a dangerous thing in the hands of someone with a 3D printer and some electronics skills. Last year he 3D printed a clear PLA box around a gift card, which is pretty amazing and totally something that I’m going to do this year. In order to top that though he decided to go all out and create the world’s most complicated puzzle box, and he happily shared it on Instructables.
The puzzle box has a total of three individual compartments, each with its own complicated way of being opened. There are two small compartments that are sized perfectly for cash, gift cards or very small gifts, while the center compartment is slightly bigger and can hold marginally larger objects. In order for each compartment to be opened it must be in a specific latitude and longitude that is programmed in using Arduino. Additionally, each compartment needs a unique six-digit code in order to open, so the recipient not only needs to figure out where to open the compartments, but they have to decipher the codes to open them when they get there. To make things even more complicated, the main compartment won’t open unless two switches attached to keys have been turned. That is incredibly inventive, and probably a little evil.
