Tactile 4-bit maze

[Oskar] has been making puzzles for some time now. In 2000, he made a small electromechanical 4-bit maze that’s really fun to play. Lately though, he’s been working on an improved version that could be the beginnings of a commercial product.

The earlier electromechanical maze (you can play it in an applet on that page) is just a microcontroller hooked up to electromagnets and switches. To complete the maze, find the patterns of bits that move everything from 0 to 1. It’s a little bit like the Fox Chicken Grain puzzle, only a bit more complicated.

[Oskar]‘s latest version uses motorized faders to represent the 0 and 1 states of the bits. The same logic in the electromechanical version is in the newest version. An Ardunio takes care of the motor control and game logic.

As a tiny logic game toy, it’s a great idea; everybody needs to get some hands-on action with Karnaugh maps sometime in their life. Check out the video below for the demo of the 4-bit maze in action.
