Well, this is technically a thread about a My Little Pony model that I'm doing; something which I don't normally write about outside of the Brony community. But, considering that this also counts as an automaton - and the first design that I've ever attempted - I guess this could be significant enough for its own build thread.
Anyways, what I plan to do is a simple piston-cam model that's based on a strangely-disturbing pony that can be seen at around the 53-second mark here: http://www.youtube.com/watch?v=KXR2usGH_Mo
So, since it's a cam-based automaton, it'll obviously just be that pony bobbing up and down out of his jar of jelly.
I pretty much have the entire piece drawn up, save for instructions and other minor details.
Here's a rough sketch of the mechanism that I worked off of:
The cam mechanism:
and a rather-uncreative housing:
