Contrivance is a wooden modular mechanism machine. Plans for Contrivance include patterns and assembly instructions for: three different size spur gears, elliptical gears, kooky gears, a geneva wheel, a linkage, a scotch yoke, a ratchet, a hypocycloid reducer, and a tourbillon.

Plans are available at: http://www.derekhugger.com

For the knowledge collectors out there, I've worked out and documented the math governing the motion of some of the mechanisms. You can download free PDF files of that math here: http://www.derekhugger.com/tools.html
