How things work.

All sorts of mechanism. What they do and how they work.

An offline version of the mechanisms section originally from the flying-pig website is available in the shop. More details here.

I'm in the process of producing a set of updated mechanism pages with more information and animations that work on more devices. You can see them here.

Here it is: Every download, every project, every e-book, every zine. Dozens and dozens and dozens of projects all in one place.

Mechanisms are used to convert between one type of motion and another. Any machine can be looked on as a group of interconnected mechanisms which convert one type of motion to a variety of other motions.

These changes may be to convert rotary motion to straight line motion or to convert reciprocal (back and forth) motion to intermittent motion. They may also transform a fixed type of motion, for example by magnifying a linear motion or by slowing down a rotary motion.

Here, motions are divided into six basic types. Click on each of the links below for information about each of the motion types and the mechanisms that can be used to convert them.
