The previous cipher seems to remain unsolved, even though it is indeed solvable. It was originally created by a hermit living in the Adirondack mountains, and was first deciphered by Dave Greene. He subsequently wrote a message in the cipher and passed it to me as a challenge, which I managed to decrypt in a couple of days.
Anyway, here’s this week’s cipher.

This is just a string, by the way, rather than a matrix. And here’s a completely arbitrary picture of a rod connecting two wheels:
Good luck, and enjoy!
