The Maze of the Lost Electronics Technician

Ariadne, Theseus and the Minotaur, Chartres, ‘The Name of the Rose’, to name but a few – there’s no shortage of mazes in our imagination. What’s more, to please the calculator wizards, Elektor has already published a number of labyrinthine puzzles that have proved pretty tough. Now this time we have a variant in the form of a circuit diagram, which we’ve kept deliberately simple so everyone can have a go. The grid contains only passive components, whose DC behaviour is easy to understand.
Enter the maze and leave it with a prize worth over £800.
