So a teenager having our Dutch fall-holiday wanted to make something. We decided on a Cryptex.
The Cryptex is a prop from the movie "The Da Vinci Code" where they have to decode the Cryptex to open it. It is suggested that the Cryptex is a design from Leonardo Da Vinci, but I can't find any proof of that in a very very thick book I have about Leonardo Da Vinci.
I think we did very nicely so here is our try on this already well documented subject.
To open the Cryptex and get to its contents, you need to turn a couple of rings with letters on it to form a word.
The most important (and hardest) preparation for this project is getting four pipes that fit inside each other. Luckily I have bought an old crashed hang glider some time ago and the leading edge of this glider has already three of the four pipes we need. (please don't shoot hang gliders out of the sky for this project)
We started the build without knowing what our fourth pipe would be, but we where sure that we would find something.
